2018 CHEVROLET SILVERADO 1500 Electrical System Problems

My transmission blew up and I almost wrecked my truck. No engine lights came on, and still no engine lights are coming on it only has 69,000 miles on it and has never missed a service. Its currently at the dealership where I bought it from

Number one electrical system left side wire harness manufacturer installed in properly, not watertight and ran through a pinch point causing wires to break. Safety was put at risk due to power failure from fuel pump and brake lights failing which could’ve caused a potential accident. Been confirmed by an independent service center. Reached out to the manufacturer. They said there was no recalls. It was very unhelpful. On the failure happened a light did come on. Number two media end navigation system this is a safety risk because at certain times it will switch between screens at will by itself. They will also put calls on hold, causing you to instinctively reach for your phone and taking your attention from driving as well as switch off of navigation moving your attention from driving, this is a clear definition of distraction and not serving the purpose it was created for which is also been confirmed by an independent shop. I reached out to GM. They said there was no recalls. And there is no service light. P.s.I just found out that I could make a complaint here so I do not have any of my old documentation. I just went to the dealership this morning to try and get some help and I had no luck. They would not be helpful at all. They just want to sign me up for a service meeting and charge me another $500 to look at it only to tell me they can’t order me a wearing harness again.

Truck was intermittently losing power steering and shutting off/reseting itself. Was a loss of electrical and was throwing Stabilitrak Service warning. Would not stay on due to truck resetting itself but loss of power happened typically when I was in parking lot or driveway. Could have easily been on the highway which could have been deadly. Dealership found that the battery cables and module were not getting enough power to truck. Replaced these and it seems okay now. Total cost was ~$1200. I see several recalls for battery cable issues but nothing pulling on my 2018 Chevrolet Silverado 1500 LTZ crew cab.

To Whom It May Concern, Below is my support statement regarding recurring safety and reliability issues observed in the vehicle over an extended period: 1. Sensor Malfunction and Resulting Damage The front and rear proximity sensors exhibit repeated failures. During reversing, the system issues false warnings when no obstruction is present. Conversely, while driving forward, the system fails to provide warnings when approaching walls, sidewalks, or other fixed objects. These failures have directly contributed to multiple instances of exterior damage, including impact with hard surfaces, as well as damage to tires and rims. 2. Warning System Deficiencies The engine warning system has proven unreliable. Significant oil leaks occurred without any corresponding check engine notification. On separate occasions, the check engine light illuminated briefly before extinguishing without resolution. 3. Diagnostic Inconsistencies Independent diagnostic inspections identified multiple ECM fault codes. However, upon subsequent service visits, these codes were cleared or dismissed without adequate explanation, creating uncertainty regarding the vehicle’s underlying condition. 4. Excessive Repair History Despite Limited Use Over the past several years, the vehicle has required multiple costly repairs despite being operated only for routine transportation. It has not been utilized in off-road conditions or to its full 4x4 capacity, yet has demonstrated significant and repeated mechanical deficiencies. The issues experienced indicate systemic failures in critical safety systems, monitoring functions, and diagnostic reliability. These unresolved defects have resulted in repeated safety risks, physical damage, and disproportionate maintenance requirements

No check engine light come on until continued driving over 15-20 miles. Transmission slams into second gear when taking off or when stopping it may or may not downshift into first causing safety issues when in traffic. Possible electrical error or clutch inside transmission. On this model it is a sealed transmission so no way of identifying if metal shavings come out with a transmission flush. The issue only happens when vehicle is at temperature, if under and still cool drives perfect but as soon as it hits the temperature of 210 it slams very ugly.

1. The components that failed were the transmission because the vehicle was driving and continued to slow down until it came to a complete stop gradually, and had to be pushed home. And also, there was an issue with the doors unlocking on their own and all windows rolling down by themselves. 2. The safety risk was the issues that happened without any knowledge of any issues at all with the vehicle. And the vehicle could have stopped on the highway, and another vehicle could have run into it, and it could have been a very bad incident. And with the doors unlocking and the windows rolling on their own could be exposed to unsafe environments and possibly theft of the vehicle or harm to the occupants. 3. Had a scan done, which showed the issues that were going on with the vehicle 4. I haven't had a chance to have it taken to the manufacturer because it broke down, and I was waiting for some help to get these issues repaired from the manufacturer. And needed from ACC. 5. There wasn't no indicators or lights on when this happened? I was told by a coworker about the windows being down, and with further investigations, I found the doors were unlocked as well, which was done automatically without my control.

I’ve had to have the transmission replaced before hitting 123k miles There is a constant shake, tremble in the car that dealer mechanics cannot figure out and they relate the issue to the transmission Electrical dashboard and ac lightning fixture burnt out

Doors automatically lock with the keys in the ignition and running locking in anyone who is still in vehicle who cannot open to door physically. It will also prevent you from entering the vehicle without a second set of keys or other methods of unlocking the door (onstar, locksmith). This could put occupants in danger and exposed to the elements unexpectedly and also place inside children in danger. Diagnosis - Keyfob - If battery in keyfob is low, the programming of the vehicle is set to automatically lock even if vehicle is in the ignition and running. when unlocking vehicle with the defective fob, vehicle will unlock, then immediately lock preventing entry. Remedy - Replace battery in key fob and truck works as normal.

The truck started shuttering one day it was like I was driving on the drunk bumps but I wasn't. Also it will drop gears when it shouldn't and at times it will kinda jump like it's losing power and don't want to go. I have taken it to my step dad who has been a transmission mechanic all his life and he said the transmission needs to be rebuilt but even rebuilding it won't solve the problem because it is a flaw in the way it was made so rebuilding it they use the same parts and everything so it will eventually do the same thing again it's all just a matter of when. He also had me go to another really good transmission guy and he said that we could replace the torch converter but still may need a rebuild l. I don't know if any that has to do with my passenger tire wear or my wheel bearing coming loose while driving only one bolt was holding it on when my husband checked it. The wheel bearing coming loose is pretty big safety problem. As for the transmission my step dad works at a transmission shop and he said they get probably 3 to 5 trucks a week having the same problem mine is having and I know they have been recalls on other trucks that have the same problem as mine just my one wasn't in the batch they recalled .

Have had 3 rear door actuator locks fail. Refer to complaint 11538814. Will be able to upload files at request.

Entire system (everything) shut down without warning, sometimes kick back on, and other times not at all. Extremely dangerous as it will occur no matter traveling on highway or turning a corner in a parking lot. There are discussion boards in which many people have experienced this problem and clearly it is because of "Bad Battery Cables" and common within the 2014-2018 models. My truck is currently in a dealership garage to have the cables replaced and I have to have a rental car while the cables are on backorder for 5 to 10 days (maybe longer). How is this not a "recall" when so common and so dangerous? Dealership could see in a diagnosis that power had been lost and communication lost, over and over and over. There has never been a dash warning light come on at all.

Hi i toke in my truck twice because of it was jerking was told it was fine noting was wrong my truck is now doing it so hard it feels like I been hit by another car

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds and in also while reversing, the “Trailer brake system Service” and "Stabili-trak Service" messages were displayed.

Mileage: 95,000

Vehicle shuts off while driving in traffic at low and high speeds stabilitrak service light comes on and the vehicle dash goes dark Radio and temp control panel go dark/ black

The trailer brake signal will alert an unnecessary amount of times randomly.

The following Recalls were found on Kelly bluebook, that matched the issues I have been having with my vehicle perfectly. When calling the recall center, they stated my vehicle year 2018 Chevy Silverado and serial number were not listed for this but it's the exact diagnosis of what I'm experiencing. The Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash. As the vacuum level drops, the brake assists decrease, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash. What component or system failed or malfunctioned, and is it available for inspection upon request? The brakes inflate on their own as if someone is pressing them down while driving. The vehicle begins to jerk horribly causing the inability to steer or maintain control of the vehicle or the ability to stop. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes How was your safety or the safety of others put at risk? This is very dangerous. I have no control over the speed of the vehicle or if the brakes will fail, or if the brakes will burn up due to fighting with the accelerator while driving. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, the manufacturer inspected it and stated they could fix the issues, paid but then the same malfunction kept happening even after payment and supposedly being fixed. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None related to the issues, Stabilitrak warning and then random hill assist to inflate the brake vacuum

Rear window defrogger overheated and caused the back electric sliding window to shatter and when door was closed the window blew out!

I have a 2018 chevy Silverado 1500 crew cab, I’ve been having problems where the truck warning light would come on saying “service stability control” and the truck would turn off when reversing and while driving on highway and the light flickers and the steer wheel would lock up as well, please help me out, I have searched over the web and have seen other people posting about it and having the same problems but yet Chevy has not done anything about it, this is a safety hazard

The component or system that failed or malfunctioned, FUEL PUMP ( METAL FLAKING IN FUEL SYSTEM ) has caused 1 or more CYLINDERS to FAIL. It is available for inspection upon request. My safety as well as the safety of many other motorists was put at high risk due to the fact that I had a 40ft. trailer hitched to the truck at the time the engine power was reduced. thus causing my vehicle to loose power while driving on a major highway. The 2018 Chevy Silverado was diagnosed by the Chevrolet Dealership doing-business-as ASCHENBACH CHEVROLET located at 925 East Main Street, Wytheville, VA 24382. The vehicle has not been inspected by the Manufacturer. When pressing down on the gas pedal, the truck would not accelerate as normal, then a message appeared on the dash-screen ENGINE LOOSING POWER.

The vehicle has just completely died on me at least twice while driving it, the power steering keeps cutting out, and the headlights will dim significantly upon pressing the brake pedal or using turn signals. This has been going on intermittently for months. Upon an internet search, this does not appear to be an uncommon issue.

The control module for the passenger side air bag failed. A warning light depicting the air bag was continuously displayed until the module was replaced According to the dealer service department, the air bag would fail to deploy with this failure.

My trailer brake system service light is on. This is due to a faulty wire harness. This issue is also causing the Stabilitrak service light to appear.

UNKNOWN The ignition, steering wheel, and electrical. While driving it flickers off and on, turns off the engine, unlocks my doors and turns on again. Yes, our safety as well as others are put at risk this can cause an accident to happen on the road while driving, most likely to get rear ended. Today it gave me a scare because my 2 year old granddaughter was in the truck.

Vehicle started to fill with smoke. I exited vehicle to look in the back seat when all of a sudden the rear window exploded causing glass to come flying at me. There was a recall for this exact same issue, however gm says this vehicle is not included in it. Obviously there are more vehicles that need to be recalled!

Service parking brake system keeps coming on, switch has been replaced and it still comes on. I have had the traction control light and service abs light come on. Took to shop they told me there was a broken wire the first two times in the harness

While driving down the highway, I heard a ding and the service trailer brake message appeared. Several minutes later, while driving about 30 mph and coming to a stop, I heard the ding again, the service trailer brake message appeared again, then all electric components died. I had no lights or gauges working, the radio turned off, the a/c turned off, I loss all steering capabilities as my steering wheel locked in place, and the engine died. All of this occurred while the vehicle was still in motion. As I pressed the brake and came to a stop, the electronics regained power. A message appeared telling me to lower and raise the driver's side window. I came to a complete stop. Even though the electronics returned, I had to restart the engine. I put the vehicle in park, turn it off with my key, then start it again with the key, all while stopped on a very busy highway. I was able to drive the vehicle home with no further issues. I have not contacted the dealership yet, as they are currently closed as I write this. I will be contacting them and informing them of the issue. I had mentioned a similar issue to the dealership a few years ago. They made a report of the incident, but said there is nothing they can do if they cannot replicate it. This is very dangerous. Losing all electronic functions, including the ability to steer and having the engine die while driving is scary. I can lose the ability to guide my truck and crash the vehicle into something or someone. This puts my family at risk and anyone else on highway that may be in proximity. There is no telling when this will take place. I have had electrical issues randomly happen while starting the vehicle, but not while driving. I may go weeks or months between electrical startup problems. My vehicle is available for inspection upon request.

The hood latch sensor has gone out and says that my hood is open when it is not. The problem is that the security alarm reads it as someone’s tampering with my hood and sets off my alarm. At this time i am unable to lock my truck because the alarm constantly goes off. The dealer has said this is happening so often that the part is severely back ordered.

The service stabiltrak and trailer brake system warming light comes on. The dealership said that it is a wire harness

The truck has has multiple issues.RR taillight always blows fuse,which I think sometimes stops my back sliding glass,I have no power to it,this has been an issue since day one,always have to carry fuses,then not long after having the truck,it has stabili trak issues,it stalls when first put into drive.delayed take off sometimes the truck jumps forward and revs the rpm’s up to 1000 X rpm sitting then it jumps to a fast hard takeoff.the truck does something called chuggel and buck I believe,it bogs way down,and then again it’ll slip buck it kicks jerks and also harshly engages.I love Chevy and haven’t given up hope just yet.this is my first Chevy.

While driving in the daytime voltage at the dash dropped almost 9 volts but when I turn the headlights on, it goes back up to 14 volts I’ve had this problem since I got the truck January 5, 2022

Service Trailer Brake System message appears and disappears constantly, check engine light.

I have done some research and found other trucks same year and make have had the same problem and have had recalls but the problem is when I hit the break the lights will all flash like the truck is going to stall and it will say service trailer break system and stablitrak system and will even shut my truck off while I’m driving causing me to have to either pull of the side of the road and start my truck back up

Sudden loss of vehicle electrical power as well as steering and break control due to faulty negative battery terminal. Engine will stall and steering wheel will kick back and issue a stabilitrak service message. Vehicle will become inoperable while still moving with no way to control.

2018 CHEVROLET SILVERADO. CONSUMER IS SEEKING REIMBURSEMENT FOR REPAIRS MADE TO VEHICLE.

Radio will not let you use part of the screen that controls the phone system. Can not use hands free calling. Cannot us any buttons on the bottom of the radio or the left side. Complaint #11479518 was also filed

Faulty injector connectors get a loose connection and make truck shutter and check engine light come on . This has happened 3 times already and had to replace one faulty plug . This is all over the internet from other l5p owners. Yet gmc want do anything

Radio changing channels by itself, menus changing by itself, instrument screen changing from info to audio by itself, calls being made to last number by itself, navigation image jumping to different areas by itself not showing the vehicles location, causing confusion when trying to get directions. All this is very distracting for driver and could possibly cause distraction enough to cause an accident.

While driving down the road, I received several non stop alert messages stating "Service Trailer Brake System". The messages were non stop and while I did attempt to acknowledge them and dismiss the alert, I was distracted from driving and had to pull over to attempt to acknowledge or dismiss the alert. After several minutes, I was able to dismiss the alert and continue on my way. This happened on Tuesday evening around 5:00 pm on August 30, 2022. I called Mike Anderson Chevrolet on Wednesday August 31, 2022 around 12:30 pm to advise them about the situation and was told it was water in the wiring.

Radio is malfunctioning. Radio would randomly change channels. Than the radio would have a line in the bottom of the screen. Than the half the radio just quit. Now the radio or phone calls does not work at all. I do not have access to hands free calls. I believe there is a recall on the same stereo for the 2019 models. It has not been inspected but is available for inspection. No warnings lights prior to the radio not working. I have a video but I do not know how to attach.

I have a 2018 Chevy Silverado 4WD, Crew Cab truck purchased brand new in 2018. Over the last year, I have had intermittent, and relentless chiming of the "Service Trailer Brake System". This occurs any time, completely randomly during normal, everyday driving and while NOT towing. it is horrendously distracting, and won't stop once it starts, even after clearing the message, it will continue to chime again every 1-2 minutes until I park the truck and turn off the engine. I have taken it to my local Chevy dealer, they can't find anything wrong with my truck. I have checked fuses, switches and relays, to no avail. I see this is not a "once-off" problem, it would appear 10s of thousands of consumers have had the same issue posted about blogs, YouTube and more around the internet since at least model year 2017. This is a complete safety hazard and unacceptable! The chime is a distraction and prevents other vehicle safety features from being usable when it is going off. In addition, I imagine if I WERE towing, that means my braking system would be rendered unusable. That doesn't seem acceptable and there should have been a recall on this already based on my vast research. I am angered that this keeps happening even under normal driving conditions, and it is a defect of the trailer wire harness system, not something any vehicle owner has done, not due to abuse, or even normal wear and tear. I am angered that even my dealer can't find and fix the problem. However, it should not be my responsibility since this is a clear and obvious defect amongst nearly 100,000 similar model vehicles. I do not feel this is safe in any way and there needs to be a remedy "recall" performed so that other owners and myself can get this taken care of once and for all. Thank you.

Service Trailer brake system audible message appearing due to faulty wire harness between body control modules.

The electrical power steering failed on my way home as I turned in to my street my steering became very hard to control nearly causing me to crash into a neighbors vehicle. This is the second time my electrical power steering has failed. About a year ago the original electrical power steering went out and a new one was purchased from a dealer ship and installed by a automotive company. Here we are a year later and it has gone out again but this time almost causing me to crash during a turn into my street. NO WARNING to me at all that my power steering was about to go out. Yes. My 2018 Silverado truck is available if an inspection request is asked of me.

A faulty internal computer constantly beeps a warning about "trailer brake system" when there is no trailer attached to the vehicle. The beeping is extremely hyperactive and non stop and distracts you from safe driving and interrupts all other audible functions (such as turn signal blinking & navigation voice commands) to render the vehicle unfit to drive.

At a low speeds while taking a turn, the electrical system clicks off and then clicks back on after about a second. Im able to see the voltage drop while taking the turn. When this happens, the power steering goes out while taking the turn. This exact incident is consistent with the recall of the year 2014 Silverado as stated in this article https://www.zehllaw.com/another-gm-recall-800000-chevrolet-silverado-gmc-sierra-trucks-faulty-power-steering/

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 45 MPH off the highway towards his home, the electronic gauge started fluctuating, indicating a low voltage failure. There was no warning light illuminated. The contact stated that he parked the vehicle in the driveway and turned off the vehicle. The contact then attempted to restart the vehicle however, the vehicle failed to restart. The manufacturer was notified of the failure and recommended that the vehicle be taken to an authorized dealer for service. The vehicle was towed to the dealer but was not repaired. The failure mileage was 43,364.

Mileage: 43,364

Rear Back up camera not working. Blue Screen on dash. This is a very common issue with GM

The power steering will randomly go out when turning at slow speeds, or when parking. The entire truck has lost power steering and then lost all power to the vehicle for a split second then return to normal power.

The rear driver side lamp started flickering and eventually was completely dead. On inspecting, it was found that the earthing brown wire pin in the connector was completely burnt and it also burnt the area right on the spot where it connects to the lamp panel.

For months now, my 2018 Chevy Silverado 1500 has a “service trailer brake system”notification on the the dash that repeatedly pops up every 5-15 seconds while the vehicle is on, including while driving. This, along with the pinging sound that comes with the notification, makes the vehicle difficult to drive due to the constant distraction the notification makes. I have tried taking issue with the dealership but they are not helping whatsoever. From my own research online, I have seen hundreds of other people experiencing the same issue. Please help us eliminate this distraction by forcing a recall and thus making the roads safer for everyone. Thank you.

10 degrees outside starter motor will freeze up and not want to start the truck. had 3 mechanics not a deal all look at it, tested the battery and came to the starter motor is defective. to have the starter replaced at the dealer for its under warranty.

Circulating air does not engage, toxic fumes enter cabin. Almost causing me to black out, I have thrown up. Have complained,, but chevy calls this "usual or expected" Have read on forums that I'm not the only one dealing with this.

Trailer Brake Service Warning

Bought the truck new. Never towed a trailer till well after warranty. Service trailer brake light keeps coming on continuously. Then no trailer lights or trailer brakes. Found 2 blown fuses but now the same thing is happening again. After my research I found tons of information that lots of other people are having the same issues. I have not pulled my RV since because I'm worried about it not having brakes. It's quite large and without them this truck would not be able to stop in case of a quick emergency.

Twice now GM has recalled the block heater for my truck. The first remedy did not fix the issue and had to be recalled again. This was back in July 2021. It is now the end of November 2021 and nothing more has been done. My truck requires a block heater in order to start in the upcoming cold months. This will make two years in a row I cannot use my truck when the temperatures fall below freezing. It directly affects my livelihood because I need a truck for work. What more can I do to speed this process up? How is it GM can still sell new diesel pickups with working block heaters, but are not required to fix the older diesel pickups?

Trailer brake system failure we noticed the sudden drainage of power resulting in death of battery multiple times alert was present after we notice the loss in voltage in battery to battery drainage after research I found that it is usually a short or a bad wiring harness which causes this and could pose a danger considering how I at one point in time have trilled things this could be an issue and a danger to others on the road

Truck loses power driving down the road. The service trailer brake system warning comes on the dash. The battery dies because of this also.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that the vehicle was parked and failed to start. The vehicle was towed to the residence. The contact stated he replaced the battery and was able to start the vehicle. The contact stated that the failure reoccurred while the vehicle was parked.

Hood latch sensor throws an engine fault code. The code says it cant determine if the hood is open or closed. After about 2 weeks the hood latch sensor keeps faulting every 1 second to 4 seconds for an extended period of time.

The DIC and infotainment both change settings on their own. It will change radio stations or call people on the infotainment and the DIC will change information displayed. The safety issue is it will also flash that the trailer has been disconnected/connected and when it thinks the trailer has been disconnected the trailer brakes will fail to function. It is a known problem with the display issue but I am unaware of any reports on trailer brake function. I have had a few serious conditions on two trailers when the truck does not recognize the trailer being connected and fails to apply the brakes.

The contact stated while driving at various speeds during high weather temperatures, it was discovered that the air conditioning system failed to activate and cool the vehicle.

WHILE WAITING TO ORDER A MORNING COFFEE AT A LOCAL COFFEE SHOP DRIVE THRU (STATIONARY), THE REAR DEFROST/DEFOGGER CAUSED ONE OF THE GLASS PANELS OF THE REAR WINDSHIELD/BACK GLASS TO SHATTER/EXPLODE. THERE WAS ALSO SMOKE & AN UNMISTAKABLE ELECTRICAL BURNING SMELL PRESENT AT THAT TIME. PLEASE REFER TO GM CANADA RECALL N192220470, AS I BELIEVE THIS SHOULD BECOME A SAFETY RECALL IN THE UNITED STATES OF AMERICA AS WELL.

WHEN THE VEHICLE WAS STARTED, A LOUD SQUEALING SOUND WAS HEARD COMING FROM THE VICINITY OF THE FRONT OF THE ENGINE. WHILE UNDER THE OEM BUMPER TO BUMPER WARRANTED PERIOD, CHEVROLET DEALER NUMBER ONE WAS NOT ABLE TO DETERMINE THE PROBLEM OR REPAIR IT. FURTHERMORE, THE PROBLEM WAS NOT REPORTED IN THE VEHICLE HISTORY AS REPORTED. A SHORT PERIOD LATER, CHEVROLET DEALER NUMBER TWO WAS ABLE TO LOCATE THE PROBLEM AND REPAIR IT AT MY PERSONAL EXPENSE AS THE WARRANTED EXPIRED ON TIME AS OPPOSED TO MILEAGE. I LEARNED THAT THE SAME PROBLEM WAS A PART OF A PREVIOUS RECALL WHICH DEALT WITH FAILURE OF THE BRAKE ASSIST PUMP. GM RECTIFIED THE RECALL BY CHANGING THE COMPUTER SOFTWARE TO OVERDRIVE THE PUMP BEYOND IT'S ORIGINAL DESIGN SPEED. THIS PROVIDED AN INCREASE IN PRESSURE WHICH TEMPORARILY CORRECTED THE FAILURE. THE CORRECTIVE ACTION ADDED MORE STRESS TO THE ORIGINAL DESIGN OF THE PUMP AND NOW THE PUMP IS MECHANICALLY FAILING AS A RESULT. THIS FAILURE COULD POTENTIALLY CAUSE AN IMMEDIATE UNEXPECTED BRAKE FAILURE POTENTIALLY RESULTING IN FRONTAL COLLISION AND LOSS OF LIFE!. THE DEALERS HAVE NOT PROVIDED COPIES OF SERVICE ORDERS OR REPLACED PARTS. I ONLY HAVE RENTAL AGREEMENTS TO SUBSTANTIATE THAT SOMETHING WAS DONE TO THE VEHICLE. GM'S CUSTOMER CARE IS INVESTIGATING THE UNPRECEDENTED BEHAVIOR OF THE FRANCHISED DEALERS WITH NO REPLY TO ME AT THIS TIME.

WHILE DRIVING AT APPROXIMATELY 65 MPH ALL ELECTRONICS SHUT OFF AND TURNED BACK ON MOMENTS LATER. THIS INCLUDES THE GAUGES, RADIO AND ALL LIGHTS INCLUDING HEADLIGHTS. I TOOK IT TO THE DEALERSHIP IN WHICH I PURCHASED THE TRUCK FROM. THEY DIAGNOSED IT AS A LOW VOLTAGE BATTERY AND THEIR SOLUTION WAS TO CHARGE THE BATTERY AND RETEST THE SYSTEMS. HOWEVER THEY COULD NOT TELL ME WHY IT WAS LOW. THE SERVICE MANAGER WOULD NOT LOOK INTO FURTHER TESTING TO CHECK THE ISSUE AS THEY HAD MET ALL THE NECESSARY STEPS LAYED OUT BY GM UNDER THE BUMPER TO BUMPER WARRANTY. HE HAD TOLD ME THAT THEY WOULD BE HAPPY TO DO FURTHER TESTING ON WHY THE BATTERY HAD A LOW VOLTAGE CONDITION IF I WERE TO PAY OUT OF POCKET FOR THE COSTS EVEN THOUGH MY TRUCK IS STILL UNDER BUMPER BUMPER WARRENTY. THE SERVICE MANAGER ALSO BLAMMED THE COLD WEATHER CONDITIONS AS IT IS CURRENTLY IN THE LOW 20'S OUTSIDE. I HAVE ISSUE WITH THIS DIAGNOSIS DUE TO ME DRIVING 60 MILES A DAY FOR WORK AND ANOTHER 30 MILES TO DROP IT OFF AT THE DEALERSHIP, THE BATTERY SHOULD HAVE BEEN AMPLY CHARGED IN THAT TIME FOR THEIR TESTING. ALSO THE DEALERSHIP REPLACED THE BATTERY WITH A NEW ONE 8 MONTHS PRIOR WHEN I FIRST PURCHASED THE TRUCK. I AM CONCERNED FOR MY SAFETY AS THE HEADLIGHTS TURNED OFF WITHOUT WARNING DUE TO A LOW BATTERY AND THERE HAS BEEN NO PROPER DIAGNOSIS OF WHY THERE IS A LOW BATTERY CONDITION.
