Lost brakes and couldn’t stop the truck
Lost brakes and couldn’t stop the truck
The windshield defroster and heater blower speed reduces and/or shuts off shortly after accelerating to highway range speeds. Blowing snow from Alaska roads will melt and refreeze on the windshield reducing visibility creating a safety hazard. The truck has not been successfully repaired after multiple and lengthy attempts. The heated steering wheel also malfunctions intermittently. The blower motor does seem to come back up to speed when vehicle speed is reduced to city speeds but is intermittent also.

1.)When driving the vehicle it will randomly shutoff while driving with loss of brakes and steering until it will randomly turn back on.The vehicle experiences intermittent electronic and drivability malfunctions. The issue appears to involve one or more vehicle control modules and/or electronic systems. At times, warning lights and system messages appear, and vehicle performance is affected. The vehicle is available for inspection upon request. 2.)These failures create a serious safety risk because they occur without warning while driving. The vehicle may lose normal functionality, display multiple warnings, or behave unpredictably. If this occurs in traffic, at speed, or while maneuvering, it could increase the risk of a crash or leave the vehicle stranded in an unsafe location. Furthermore on 3 separate circumstances I came close to crashing the vehicle putting at risk lives in the vehicle and outside. 3.)The problem is intermittent and has been difficult to reproduce on demand. I have taken the truck to the dealership multiple times. The dealership has stated that because the issue is not actively occurring when they have the vehicle, they have been unable to duplicate the concern and have instructed me to continue driving it until the issue happens again. Despite this, the problem continues to return during normal use. 4.)The vehicle has been inspected by the authorized dealership on multiple occasions. To my knowledge, it has not been inspected directly by the manufacturer, police, or insurance representatives. 5.)Intermittent warning lights and system messages appear, including at times a check engine light and other alerts. These warnings may appear suddenly as the truck shuts off and then disappear after the vehicle is turned off and restarted. Another thing to point out is that the audio and turn signal chime cut off randomly. The issue first began while the vehicle was already in normal use and has continued to reoccur since.

Tailgate unlatched by itself, first time I was connected to a trailer and it damaged the tailgate. Multiple (4+) times afterwards while being parked in garage tailgate opens by itself all during the same day could not get this to stop. Called dealership today for appointment where they could get me in the shop in the middle of the week, but they told me that this issue is known but not covered under my VIN.

Telematics module failed directly after update, vehicle is outside of warranty (by mileage) but only 3 years old. no GPS, Onstar, and several other features that rely on this system to operate. several dealers would not even look at it when calling for appointment, one dealer stated that the part was on back order for up to 2 years and did not want to waste the time to look at it. Upon research, this appears to be a very common problem on all GM models with similar outcome

Every time I pull the truck into my garage or a parking stall at low speeds while using the front park sensor it will shut off with the automatic start stop while still in motion. Then you have to let off the brake pedal for it to start and sometimes the vehicle will search forward.

My 2022 GMC Sierra 1500 shows message "Shift To Park" when turning off, even though it has been shifted to park. Have to play with shifter to get it to stop, sometimes turning it back on and off will do trick. Locking it with remote works most of the time but this last time it took over 10 minutes .

The dealer is telling me there is a faulty engine coolant, flow control valve on this vehicle and multiple other people are having the same issue. The part is on backorder and takes months to arrive. They are telling me I can drive the vehicle, but it becomes a safety issue because the engine thinks it is overheating And goes into reduced acceleration mode, which can impact safely driving the vehicle. Pulling out in traffic and not being able to accelerate can be extremely dangerous.

Driving 70 mph on highway and the engine shut off. Dash says shift to park to restart. Pulled over and put the vehicle in park and pressed engine start. Vehicle did not start back up. (No crank no start) Vehicle locked in park and wont shift. Vehicle was towed to my house. Replaced battery bus bar and vehicle started back up. Test drove and shut off again in my driveway. Will not restart. No engine light on. 124k miles on it. No warning of this happening. Vehicle randomly will shut off. Sometimes it turns on. Been parked since January in my garage for safety concerns until I learn of a repair.

Hello, I wish to report this injury / incident with the failure of the power running boards on my 2022 GMC Sierra 1500 Denali Limited. There are no warning Lamps on the vehicle. The truck is regularly serviced and inspected. The truck recently had a multi-point inspection at the dealer. The power running boards started to come out after I opened my door, as I stepped down, the steps retracted and went back in causing me to fall hard on the ground and smash my knees. Driver and passenger sides are now acting up, even with the truck parked and locked, passenger side wants to go in and out on its own and sometimes extends to the tire. As I researched this problem, I found out that others have had similar issues with the same vehicles that have these power running boards. I removed the fuse now to prevent further injuries.

While driving my 2022 GMC Sierra Denali 6.2L truck, it somehow turned off. I placed it on neutral and tried to turn on, but it didn’t. I maneuvered to stop at the side of the road, but I was not close enough to the curb making it uncomfortable for others to drive around. I tried again to turn on the truck, but it didn’t. Before and after everything looked good, there were no symptoms or warning lights on the truck. I gave it a break and tried to turn in the truck, but it didn’t. I called GM roadside asst., and I got towed to the closed GM Services. They found out that battery was damaged, and an open starter fuse damaged. They changed the battery, the fuse block, and did the multi-point vehicle inspection (MPVI), and everything seemed good. I picked up my truck, and on my way back home the engine stopped running. At this time I get into a left turn lane, and I was able to stop before the stop line. This time I was in the middle of the road. I turned on the Hazard Warning Lights, but too many cars turning left pass through making it dangerous to my safety and others. I called the service department where my truck was serviced and GM roadside asst., and it got towed to the same service place. All this process was again around 2 hours in the middle of the road. They checked the truck, and found out that the battery was damaged, and an open starter fuse again. They changed, but this time they kept it on test to the next day and the starter fuse was damaged again. They found that the engine was locked, which is why the starter heats up and the amperage consumption increases, opening the fuse, the engine does not turn easily, the oil is at the correct level, it does not indicate low pressure in the initial driving test. They removed the oil pan and found metal particles in the oil and in the pan. After that they removed the rod bearings and can see that they are scratched and overheated, crankshaft scratched as well. Need order a new engine, oil cooler, oil cooler lines.

Tailgate comes unlatched and tailgate came down multiple times in motion and parked. Safety concerns loosing cargo and causing accidents. My vehicle is not included in the recall and dealer cannot help only repair for 146.80. I feel that my vehicle should be included to the already existing recall and reimbursement for repair.

During the first approximately 10 minutes of most drives, the vehicles speaker systems intermittently cuts in and out. This includes the turn signal audio and seatbelt chimes. It does not happen on every drive, I would estimate that about 2 out of 3 drives this issue occurs. All sound will cut out for about a half a second up to 2 seconds. After I begin the drive this issue will go away usually within 10 minutes however sometimes it is quicker than that. I have not taken the vehicle to be looked at due to others stating the dealer has no fix for the issue at this time. The turn signal and seatbelt chime cutting out can create confusion and may cause occupants to forget to buckle their seatbelt. No warning lights or messages have appeared in relation to this issue

Hi, I was driving on [XXX] and my radio volume went to full volume 100% by itself. The radio would not shut off and none of the controls would work, everything froze. I kept turning the volume button down and the volume bar on the screen showed that it was trying to minimize, but it wouldn't stay. It kept going to full volume. Finally, after I kept pushing the off and mute buttons, the radio shut off and was unresponsive. When I reached my destination and shut the truck off and restarted it, the radio then worked as it normally should. This happened to me yesterday, and I'm still having trouble hearing and my ears hurt. I researched this online and found that there are many other people that had this same scenario with their sierra. I wanted to reach out and report this.

Radio software glitch (bulletin 23-NA-183) cuts blower fan speed to 50% or below resulting in ineffective defrost during winter months. GM knows of the issue and has a radio software update but will not complete this as warranty and/or recall and will demand you pay for the correction. Due to the uncontrolled and loss of power to fan that cannot be corrected by the owner (ex. turning radio off/on will not fix it) this has become a serious safety concern as the windshield can fog, frost, or freeze while driving the vehicle.

Infotainment system volume shot up full blast on its own with no operator control or influence. The volume of music was so high that it was hard to concentrate on driving while trying to reduce the volume and could not. Had to pull over on the side of the road and shut off vehicle to get the volume to go down. This could be a potential safety risk when driving at higher speeds causing the driver to not concentrate on the road and other surrounding vehicles. I reported issue to dealership and have not had it looked at yet as it has only happened one time. The volume indicator flashed on the screen and showed the volume indicator bar going up to full blast. No other indicators or warning were present at the time.

Rear tailgate would randomly fall down without any key fob buttons being hit. Did some Google searches and it sounds like it is VERY common. There is a faulty tailgate switch that will randomly drop the tailgate which could cause damage if you have a bike rack on or things could fall out of the truck bed while driving if it isn't noticed that the tail gate has dropped

This is the second time after already bringing in for service, while driving turning on the radio the volume goes to full volume with a Bose system it is ear piercing, none of the radio controls worked, I could not shut off the radio or turn the volume down it was locked at full volume. I had to stop in the middle of the road in Cambridge MA, Place in park, shut the engine off and open the drivers side door to shut the radio off, it took four attempts of restarting and stopping vehicle before the volume would return to normal. This is a severe SAFETY HAZARD THAT WILL EFFECT HEARING AND CAUSE AN ACCIDENT, I AM SO FED UP WITH THIS VEHICLE. I need to schedule another appointment for GMC to do nothing.

This has now happened twice. While driving down the road, my radio has went to full volume and continues to go back to full volume, even if I twist the volume control knob quickly to lower the volume. This is a very scary situation while driving down the road and your radio goes to 100% volume out of the blue. There is no warning and the volume just goes to 100%

While driving, I turned the volume on the radio a couple clicks louder using the steering wheel controls. After I stopped pushing the volume button on the steering wheel, it continued to rapidly increase volume until it maxed out. It was incredibly loud, in a panic, I verified the VOL+ button was not stuck. The VOL- on the steering wheel did not reduce the volume. I spun the volume button down, on the radio, but it would instantly return to full volume the moment I stopped spinning it. The power button on the radio also had no effect. I was driving at 50mph and had no way to reduce the volume from the max, which was incredibly distracting to say the least. I was finally able to get it to stop by pulling out my phone (which was connected via CarPlay) and hitting the pause button on my phone. Afterwards it behaved as normal, but my man did my ears hurt. Luckily there wasn’t any traffic nearby as I could hardly focus on the road while fumbling with the audio.

On June 8th I started my truck and it made a strange unfamiliar noise before starting. I thought it was bizarre. Shortly after I stopped in traffic and my truck stalled out. It stayed on but when I went to give it gas I didn’t move. So I restarted the engine and the same strange noise was made. Along with the noise I smelled something funny so I pulled into a gas station. Little did I know my truck was on fire. I got the vehicle away from the gas pumps and within 5 minutes the whole truck was on fire. Before this fire I had brought the vehicle in for service due to a check engine light multiple times the codes will be listed below. I also had an interlock device installed in the truck at the time.

On January 20th 2024 I was cleaning heavy dirt and mud off of my truck, after leaving the car wash and driving about 20 miles, once I parked my tailgate started to open over and over on its own. This happened again on March 4th 2024 after cleaning off a lot of dirt from my vehicle the tailgate opened on its own while my truck was parked in the garage. It opened into the garage door, when I left I did not know it was open, so when I opened the garage door the hinges on the garage door scraped and dented the tailgate as it opened. I had not pressed any buttons inside the truck, outside of the truck, or pressed the tailgate open buttons on the key fob. After intense car washes it has opened on its own each time.

On Feb. 27, 2024 approx. 04:15 left for gym and work. When arrived at gym and began to park, I put truck in reverse to check back line and noticed I was looking at my license plate. I then put into park and got out of truck and shut tailgate. Thinking not much about it, I must've touched the button the night before and hit a bump on way into work. Since I have a toneau cover, it fits pretty tight and I typically have to pull it down by hand. I heard about recall that day after I got to work from co workers. Checked my VIN, but did not come up as one of the tailgate recalls. March 7, 2024- Left again for gym and work approximately same time in AM. As I was driving into gym and work, another car coming up close behind me wanted to pass. The car then suddenly backed off to a considerable distance. As I got to gym and put in reverse to check my back line, I noticed I was looking at my license plate again. I know that I did not touch a button either on FAB or tailgate. because I park in garage and leave FAB in a secure place where it can not be pressed. If tailgate was down in my garage, it would have stopped garage door from opening and/or damaged my garage door. In either instances, I did not get a sensor alarm going off on my dash for "tailgate down", If its even equipped with that alarm.

While unlocked, passenger doors go through unlocking phase, door locks click, parking lights flash and tail gate comes open. Along with this, an electric motor sound comes from underneath the vehicle (pre start fuel pressurization sequence?) that goes on and on, doors locked, or unlocked, that, left unchecked, drains the battery. Must be hooked to battery recharger round the clock.

Purchase new in Sept 2022. I did not notice that my trailer hitch Connector was not working until after a year later. when i needed to hookup my enclosed car hauler trailer. And notice that my trailer daytime running lights where not working. Only brakes/,turn signals and four way flashers. I contacted my dealer and again they found no issues with the factory harness. leaving me on the side of the road until morning. As i had no running lights. After arriving back home. I crawl under the rear bumper. just to check the connections. I could not see anything nor would i know what to look for. I called another Gmc dealer and they mention that they been having problems with the module for the factory trailer connector. Still having issues

Tailgate occasionally self deploys. 1 incident resulted in damage to the tailgate while towing a trailer.
The tailgate is opening on it's own. There have been many times it has been open and we were not aware until we go to the back of the truck or put the truck in reverse and notice it on the backup camera. We first noticed it happen around Christmas of 2023, and it has been happening randomly since then.

While driving vehicle with infotainment system playing radio, radio volume goes to full volume that is ear piercing and is going to cause hearing damage. Must pull off the road as fast as possible, place vehicle in park, shut off vehicle and open drivers side door to get radio to shut off. While the issue is happening volume knob does nothing, stereo on off button does nothing and steering wheel volume controls do nothing. This is a serious issue when trying to pull over, I keep ear muffs in vehicle to protect ear drums. This has happened at least 6 times, I plan on bring to GMC dealer.

While driving, on its own, the radio volume surged to 100%. All radio controls were unresponsive, and the volume was maxed-out.. Volume bar on the console display was reading 100%. Was unable to turn the radio down or off. Issue did not resolve until I drove home and turned the vehicle off.

While driving the vehicle, the volume on the audio panel shot up to 100%. It caught me off guard and nearly caused me to steer into oncoming traffic. All volume knobs and switches were unresponsive including the power button to the whole unit. I had to pull over and shut off the truck and let it sit for over 10 minutes in order to get it to stop. There are now numerous audio issues, including but not limited to the audio speakers making a crackling noise so bad it renders the use of any audio completely, also periodically the audio loses all volume and will remain completely silent regardless in AM/FM, Satellite Radio, bluetooth or phone call. All these seem to happen anytime the truck gets wet from either car wash or the weather.

While driving the vehicle, the radio will suddenly and instantly jump to full volume frightening the driver and passengers and making it hard to focus on the road and control the vehicle. The dealership and GM will not fix the issue as it happens intermittently.

Unwanted Radio Volume Ramp Up to Max: The radio volume turned up to the maximum while driving and could not be turned down with user controls including those both on the steering wheel and the volume knob on the dash. The situation lasted about 60 seconds before it began responding again. The vehicle has the optional Bose radio system which is EXTREMELY loud. This issue presents risks with damage to my small daughter's ears, as well a significant distraction from driving due to frantic attempts to decrease the volume while being overwhelmed by the noise level.

The vehicle is brand new with only 300 miles on the clock. Today while driving to work and listening to XM-radio the volume spiked to max and would not respond to controls to lower volume or turn off. I was able to lower by switching to a different output. It was very detracting and potentially dangerous since the Bose speakers are very loud.

On multiple occasions the Radio has went to max volume for approximately 2-3 seconds then shuts off and goes through a reset. This situation can cause the driver to be suddenly distracted put the driver and others at risk of an accident.

I bought a new GMC, I received 3 vouchers for computer chips to be installed at a later time years ago. They have not provided them. They are selling new fully equipped vehicles with computers chips just fine. Can you handle and have GMC install their backlog of computer chips? There are many safety features that DO NOT work, like parking assit and basically all warnings like when backing up etc. They made me sign a form stating they are not responsible for safety issues stemming from this (our inability to sue) this should be illegal. Thanks.

While driving down the road on two different occasions the volume on the radio went to full blast and would not turn down or turn off. This caused distracted driving and could potentially cause an accident. Dealer states manufacturer is aware of issue with no resolution at this time. No warning of failure and the first occurrence was February 12, 2023 and the second occurrence happened March 5, 2023.

While towing my 7000lb car trailer, I get a message that the trailer brakes need service, then I get another message that the trailer brakes are disabled. At this point the brakes are shut off and no longer work. This is extremely dangerous. The problem is with the truck. It does the same thing with multiple trailers of tried with electric brakes. All of these trailers work fine by my other vehicle with electric brakes for the trailer.

Electrical component- Dashboard is constantly glitching, blue-tooth will not connect properly, electrical appears to turn off randomly while driving to the point we have to pullover because it appears and feels like the truck is turning off. Power step running boards malfunction- They don't open or close when they are supposed to. Power step running boards also malfunction while driving. It is a risk because we've had to pull over in conditions that aren't safe, putting a family of five in danger. The problem has been reported to the dealership and manufacturer and has gone unresolved.

On 05/28/2022 my family was driving my brand new 2022 GMC Sierra 1500 3.0 Diesel at a rate of 60mph. There was suddenly a loud clunk (transmission) after proceeding a little further and getting speed back to 60mph there was a similar “clunk”… the diesel truck then immediately gained several various check engine / sensor lights all over the dash and went into Limp Mode. Speed slowly decreased from 60mph and finally as we were navigating our final left turn to our destination the truck would not accelerate thru an intersection subjecting our entire family to utter danger of oncoming vehicles. As a last ditch effort to save ourselves I put the truck in reverse and was able to reverse about 2mph. Then proceeded to shut the truck down and turn it back on to get out of the intersection, but the truck would not come out of park. Onstar emergency was contacted to call the police as we were in an extremely dangerous situation. This truck nearly caused our entire family to get in a very bad collision. The truck was stuck in the middle of the intersection for over 2 hours. The police even attempted to help getting the truck out of park , but was unsuccessful. The truck was scanned on site and had various codes including C1555 (x4) U0101 (x2) P25A2 U220F Collision assist light Check engine light Service Traction Control Light Service ESC The truck experienced catastrophic failure at only 319 miles. Day 4 of ownership. This vehicle needs to be investigated if it is failing this early on. There also needs to be a manual release for the parking gear. Truck has no way to be placed in neutral upon failure of the transmission relay.

Check engine light came on at 458 miles. Took it in and after an hour they determined it was the ecm. They said it was bad. Now they're on the hunt for one. In the meantime, in a day the truck has started feeling like it's over shifting and then bogging down. 458 miles, really! I'm going to need a loaner for longer than I've had it and still make payments.

Truck drove as expected with no prior warnings. We pulled over for road snacks/drinks upon starting the truck we got a whole slew of warnings and warning lights. The warnings included:. Service ESC, Service Trailer Brake System, Service Brake Assist, Steering Assist is reduced Drive with care and finally Brake System Failure 43 MPH top speed. The check engine light, Traction Control Off and BRAKE light stayed on. We slowly drove to an O'Reilly's and got the ODB Code P25A2 (1 of 2 stored) and P25A2 (2 of 2 pending). I then noticed I had an email notification from OnStar Advanced Diagnostics: This is a Diagnostic Alert for your GMC Sierra. Dear [XXX], An issue with the Antilock Braking System in your 2022 GMC Sierra has been detected. Please service your vehicle within 7 days. The following morning the truck was was started and all seemed normal like nothing ever happened, no warning lights or warning messages Our of concern we dropped off at Garlyn Shelton Buick GMC service center to diagnose the issue. They reported finding code C05B0 for Brake Fluid Leak. Further states No external leaks found, Brake Fluid test passed 2 of 3 times, recommend needs Master Cylinder Assembly but No replacement parts available. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
