2022 CHEVROLET TAHOE Electrical System Problems

Vehicle continues to experience flashing air bag light and service self-restraint system warning. Brought in twice in 2025 for self-restraint system but dealer refuses to cover under warranty. On December 18, 2025, experienced complete power and electrical failure while in transit on a turning lane. The vehicle was unable to start, or open any windows, and the transmission would not shift back into park or neutral while obstructing traffic near an active railroad. Vehicle battery was replaced and was able to safely put vehicle into gear. Vehicle battery replacement allowed for normal driving; however, from that date on the transmission started shifting harder and jerkier. On December 31, 2025, vehicle was being driven on the freeway to then experience difficult shifting and reduced power. Subsequently, the drive indicator began flashing red and a service transmission indication appeared. There has been at least three instances, since vehicle purchased, where sudden loss of power and control of the vehicle in motion has occured.

I'm submitting this complaint regarding an ongoing electrical defect on my 2022 Chevrolet Tahoe. The vehicle has experienced repeated sudden battery drain & no-start events, occurring approximately once per week. These failures happen without warning, sometimes after the vehicle is parked for as little as 6 hrs. All dealer updates & software campaigns were completed. Despite this, the vehicle continued to suffer no-start events. After further troubleshooting, we removed fuse F35RA (which powers only the hands-free liftgate module). Once this fuse was removed, the issue immediately stopped — confirming that the parasitic draw originates from the liftgate module, consistent with GM Technical Service Bulletin 24-NA-039. This indicates a known electrical defect. This problem has caused multiple safety concerns: The vehicle has left my family stranded late at night. My husband works in Chicago & relies on this vehicle. A sudden no-start or complete electrical failure in that environment is dangerous. We were unable to transport our children to scheduled activities due to the vehicle being completely dead. Repeated deep discharges are damaging the battery we purchased only months ago. A family vehicle shouldn't unpredictably become inoperative. This is not normal wear — it's a safety-critical electrical defect that could strand owners in unsafe conditions, especially in winter climates. GM hasn't issued a recall for this issue despite issuing a TSB documenting the defective behavior. The frequency & severity of electrical failure suggest this should be investigated as a potential recall. I'm requesting NHTSA review this matter due to the safety implications & the repeated nature of the failures. Incidents: No-start after 6 hours parked at a friend’s home Multiple weekly no-start events before fuse removal Occurred before & after software updates were performed Location: Incidents occurred both at home & away from home. Thank you for reviewing this complaint.

To Whom It May Concern, I am writing to express my absolute shock, extreme frustration, and profound distress regarding the catastrophic and recurring failures of the BRAND NEW $86,626.50 2022 Chevrolet Tahoe RST we purchased from Community Chevrolet (200 W Olive Ave, Burbank, CA 91502). We did not purchase a used, low-budget vehicle; we invested a life-altering sum of EIGHTY-SIX THOUSAND DOLLARS in what we expected to be a safe, reliable family SUV. Instead, we have received a death trap that the dealership refuses to fix permanently. This vehicle is fundamentally unsafe to operate. We have brought it to your dealership four (4) times for the same critical safety issues, and each time, we receive the same insulting explanation: a "software update" or "recalibration." These are not fixes; they are negligent bandaids designed to clear error codes long enough for us to drive off the lot. We are experiencing terrifying, random SYSTEM FAILURES while driving: "Service ESC" warning "Forward Collision System Unavailable" "BRAKE SYSTEM FAILURE 62MPH TOP SPEED" Let me be unequivocally clear: the braking system has failed twice while my wife and three young children were inside the vehicle, nearly resulting in fatal collisions on the freeway and city streets. This is not an inconvenience; this is a life-threatening defect that you have failed to remedy. The negligence displayed by returning this vehicle to us in an unsafe condition is staggering. The financial and personal toll is immense and completely unacceptable: We have paid for tow trucks three times. We have missed work, leading to a formal warning for my wife's employment. We have incurred costs for rental vehicles and arranging essential transportation for medical appointments and school runs. For $86,000, I expect a vehicle that adheres to basic safety guidelines, not one that endangers my family and others on the road. The vehicle had approximately 56,000 miles when these critical issues became severe, yet it is

The Onstar telematics control module failed and the dealership says the repair parts are not available with no expected delivery date. This disables the Onstar system and GPS.

Wipers failed during heavy rain in heavy traffic on 7/3/25. Wipers randomly started working. The wipers failed again during a heavy rain on 8/13/25 again in moderate traffic. Wipers failed during heavy rain, was unable to see while driving on an Interstate. I was able to navigate to the shoulder of the highway but was very scary being on an interstate highway in heavy traffic. Dealership repair occurred on 8/14/25. No warnings of any kind prior to the failures.

I along with many owners have experienced the widespread OnStar/telematics module failures in the current generation Tahoe and GM vehicles, which cause onboard system outages like navigation, safety alerts, city emergency services, cellular connectivity, Android Auto/Apple CarPlay, and even instrument cluster functions sometimes going offline. The part is often back-ordered with no ETA, while GM denied warranty coverage causing the owner to pay for the replacement part and all labor.

The windshield washer fluid pump began smoking and has burnt electrical smell. Fuses for the washer pump did not blow to disconnect power from the pump. The pump continued to receive power after the key/pushbutton was turned off. This is is potential fire hazard while driving. Also a visibility hazard when the washer pump fails. This vehicle is a City of Cripple Creek, CO police vehicle. This failure has now happened on two of our Police Defenders (Tahoes).

Odometer Fraud. The contact purchased a 2022 Chevrolet Tahoe. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 55,305 and at the time of registration, it was discovered that the mileage was 88,822.

Mileage: 88,822

On May 9th, 2025 we had to have our 2022 Tahoe towed to the local dealership. There was a transmission error message and the battery was completely drained. The dealer put a new battery in it for $485 and we were told it was good to go. The next day, the car would not go into Reverse. Had to have it towed back to the dealership and was told that the Transmission failure was a recalled part and would be covered. Later we were called and told even though the part that had failed is in fact the same part in the open recall, that our VIN was not on the recall list and the cost to fix the vehicle would not be covered. In addition to all the headaches and money out of pocket (rental cars, tows, new battery) we now have to wait at least 4 - 6 weeks to receive the recalled part but since our VIN is not on the 2022 Tahoe recall list (even though it is the same part as the recall that failed), we are having to pay out of pocket for the repairs. Chevy needs to stand behind this recall and cover the cost.

The Onstar module has failed. This part is the Telematic Control Unit or TCU. This is a widespread issue with no ETA of part replacement. This is an issue that is not often covered under warranty especially for vehicles outside of the age/mileage requirement of the company. This should be investigated and issued as a recall.

Dear. My name is [XXX] . Phone # [XXX] . My email: [XXX] On [XXX] my Tahoe suddenly shut off while I was driving over 70 mph on the highway. It was towed to the South pointe chevrolet dealership in tulsa. I was told a fuse had failed and paid nearly $400. On April 17, 2025 they returned my Tahoe and said it fixed. [XXX] When i tried to start engine, then it acted like something almost can't start, then i text dealership and told them situation. On [XXX], the same failure occurred again — again at highway speed — nearly causing an accident with an 18-wheeler. The Tahoe was towed a second time. 2 times i was able to re-start engine drive until i stop then can't start it agian. Both time i smell something burned when i tried to re-start it. On April 21, I texted the service manager about GM TSB N252494000, which describes propulsion loss involving the L87 engine — the same engine in my Tahoe. Two days later, I was sent an invoice for $865.30 for a starter replacement. I was told the repair would not be covered under warranty — despite the vehicle still being under 60,000 miles at the time and the defect appearing to fall under a known GM issue. This is a recurring, life-threatening failure that GM and its dealer have not fixed. The vehicle is still under warranty, yet GM is refusing to cover the repairs.

Purchased brand new. Had for awhile and the veh shook. Took it in and the replaced with all brand new lifters. Still not correct than replaced with all new fuel injectors. Now when I take it in for the last several months it’s 1.5 to 2 quarts low on oil. Told that GM standard says 1.5 quarts low between oil changes is normal!!! I’m currently on an oil consumption test at each 1,000 miles snd I’m at 2 qrts with 1,500 til my next oil change. The volume on the radio goes up and the computer is stuck and you cannot turn the radio off or use the computer screen at all. You have to turn off the vehicle and start it again in order for the buttons to work.

The contact owned a 2022 Chevrolet Tahoe. The contact stated that, while driving at an undisclosed speed, the center console armrest suddenly burst into flames. The contact was able to pull to the shoulder of the roadway and evacuate the vehicle. Within moments, the front end of the vehicle became engulfed in flames. The air bags did deploy. Local emergency services were able to extinguish the flames but did not investigate the cause of the fire. The vehicle was towed to a tow yard and deemed a total loss by the contact's insurance provider. A fire report was filed. A police report was filed, and injuries were reported. The contact transported himself to an area hospital and was treated for a second-degree burn to his left pinky finger. The manufacturer was notified of the failure, and a case was opened. The contact was informed that the manufacturer intended to send a specialist to inspect the vehicle. The VIN was not available. The failure mileage was 73,000.

Mileage: 73

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at various speeds, several unknown warning lights were intermittently illuminated. The vehicle was taken to a local Auto Zone where it was diagnosed with an ABS - U1006 (Loss of Communication). The vehicle was taken to a local dealer where the vehicle was repaired under Customer Satisfaction Program: N242435631; however, the vehicle was left for further investigation and further repairs. The vehicle was not yet repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 60,000.

Mileage: 60,000

The check engine light illuminated cause us to park the vehicle until diagnosed. The diagnosis is the Onstar system has failed causing the check engine light to illuminate. Even without paying the fee for onstar the light still illuminates rendering the vehicle “disabled” under Indiana clean air requirements. They will not run the required emissions test to certify or plate your car with a check engine light on. The dealer stated the vehicle can still be driven however we will no longer know if there are ancillary issues because the check engine light goes on and off. Ironically this happened two months after a software recall performed by the dealer. If the vehicle is safe to drive with an onstar failure there should be no reason the check engine light illuminates taking attention away from more serious potential issues.

Continuous alert(3 months)- service transmission, unable to shift gears. Safety concerns due to possibility of transmission failure.

Vehicle reduced power and displayed many errors on the dashboard, including reduced function of forward collision avoidance, reduced acceleration, ESC SES TC. A vibration/rumble was observed (unsure if it was steering assist or propulsion surging), as well as increased engine speed without vehicle acceleration and no engine speed increase while pressing the accelerator. Turns seemed to make the symptoms worse and cycling power on the truck would temporarily clear the faults. Root cause was determined to be TSB 21-NA-149 Cause 3 and diagnosis and repairs took more than a week.

Transmission Failure/Windshield Wiper Failure- While traveling approximately 48mph, the vehicle completely locked up. Tires screeched, vehicle came to a grinding halt. Two of my children were in the vehicle (15yrs and 7yrs of age.) This was sudden and without warning! The vehicle almost rolled, and we were lucky that no vehicles were behind us or we would have been rearended. At that time, we pulled over and the vehicle was towed to the service department at the local dealership. Just days before, the windshield wipers completely failed while driving, in the middle of a downpour. I had to pull the vehicle over and wait for the rain to calm before returning home. Also, the entire display panel went blank while driving, as if the vehicle was turned off. I was unable to determine speed etc. There had been a cascade of odd malfunctions days prior to the major events, the clock stopped working, the compass stopped working. The service department informed me that there was a "Bad Valve Body." I was told by the service manager that he had "never heard" of a vehicle doing this. My children and I are terrified to get back in the vehicle, as we almost had what could have been a fatal accident. I am in contact with GM/Chevrolet on possible remedies. I should note again that there are several other defects with the vehicle, that all seem to surround microchip/electrical components. They all seemed to have failed at once, which leads me to believe there is a larger systemic problem with this vehicle, the processors, and components. Again, this was a sudden cascade of failures. I have video of the windshield wipers non-functional during the rain. I was able to take the video after I had stopped. This is exceptionally dangerous. This vehicle is available for inspection. There were NO warnings lamps or messages. NO insurance has been involved. To my knowledge the dealer has not re-created the failures, but I have video of the panel black out as well.

While driving on highway radio, turn to full max volume and became unresponsive to any other inputs. Steering wheel volume control as well as radio volume control and power buttons were not responsive. Max volume was only resolved by turning vehicle off and back on 30 minutes later. This has happened several times in 2 years.

The radio volume turned all the way up on its own and would not turn down. The control screen would not work, radio power dial would not work. Steering wheel volume buttons would not work. I could turn the dial down, but it turns back up as quickly as it goes down. This caused me to panic and almost crash as I was on a major highway and there was no place for me to pull over.

Tahoe will not start nor will it allow to be jumped by another vechicle. Tahoe is kept in garage this is the 4th time this has happened. Dealer replaced the battery first time saying that was the culprit, second time they could not find a root cause, and same for third time. I see this is a common problem with engine, battery and electrical of the 2022 tahoe. I do not feel safe in it knowing this could cut off on me driving down the interstate.

DEAD BATTERY 3 TIMES in a 35 day period. We drove vehicle (2022 Tahoe) 15 months without any issues. February 9, 2023 we had the main instrument cluster not come on when vehicle was started, we cut off / restarted vehicle and instrument cluster came back on with no further issues to date. Vehicle did some type of over the air update after February 9, 2023 and before February 26, 2023. Vehicle gave a low battery light on February 26, 2023. Vehicle was taken to Chevrolet Dealership on February 27, 2023 and returned to me on March 1, 2023 with a new battery installed. March 19, 2023 vehicle battery died with roadside assistance called to jump off vehicle. Returned vehicle to Chevrolet Dealership on March 20, 2023 and was told the radio was not turning off as designed and there was an open sensor in the windshield - both items repaired and vehicle returned to me on March 21, 2023. April 2, 2023 vehicle battery died with roadside assistance called to jump off vehicle. Returned vehicle on April 3, 2023 to Chevrolet Dealership. Vehicle has been at Chevrolet Dealership for 3 weeks. As of today, April 24, 2023 Dealership / GM state that they cannot find anything wrong, but want to pull the fuse out for the liftgate module and return the vehicle. I asked why not replace the liftgate module and am being told that they do not know that the lift gate module is the issue, so they will not replace module. At this time I see no evidence that the root cause of battery failure has been identified and GM / Dealership is wanting to return the vehicle to service on the hope that pulling a fuse for the handsfree liftgate module will resolve the issue leaving my family at risk of another battery failure.

With 8500 miles while driving the engine started ticking, jerks on acceleration, Trans shifting very slow and a light warning with “reduced acceleration while driving” came on. Then immediately after the Instrument panels warning lights indicated service traction control, forward collision system unavailable, and check engine light all illuminated. Then car stopped accelerating and was almost rear ended on highway. Luckily no one was hurt. What is GM/Chevy doing to fix this issue. Apparently, this is common issue with the new Tahoes.

Brake control module failed and is available for inspection. It is still at the dealership as the part needed for repair is backordered. I had trouble braking and steering vehicle putting myself and others at risk but fortunately was in a parking lot at low speed. Problem has been inspected confirmed by dealership only. Warning lamps/messages first appeared at time of incident, none prior.

Hi, My truck was ordered May 2021. Came in January 22, 2022 as a 22 model year. Its a 4 wheel drive with the Duramax diesel option. Ran great until around 6000 miles where I started to experience a miriad of electril issues including a completely malfunction anti collision system, transmission problems, several electrical problems and worst of all "Reduced Acceleration" otherwise known as "Limp Mode" in diesels. The check engine light came on also and my MPG dropped from 18-28 mpg to 12 mpg.The dealer told me that they were backed up with diesel trucks and to hold off. On July 8, 2022, the truck went into limp mode while trying to accerae onto a major highway. I had the horn blown at me and almost got rearended trying to get on the highway. I had nowhere to go and it took me about two minutes to get up to 60mph. I got off the highway and limped to the dealership. The truck spent 122 days in the dealership and despite me trying to lemon the truck, they said it was fixed after around 110 days. I was forced to pick it up. It broke down in the parking lot before I could drive out of the dealership. I am now taking action agaisnt GM. This is not a Chevrolet issue with the dealership but GM. Their factory reps rebuilt some wiring harness in my truck. Something to do with the transmission module. Again, I dont have a problem with the dealer. The truck seems to be running fine but I have notice some strange behavior with the forward anti collision system and the auto brake. It doesn’t work all the time. I can,t tell when it will work and if it works at all. I will be bringing the truck back to the dealership. Now, this is a major problem because im not the only one complaining about the anti collision system. I know someone who says his same year diesel Chevy pickup has an issue with the camera not working in the front and he doesn’t trust the anti collision system as well and he is in the business. This is a major problem GM is hiding from the public.

Dash was blank when vehicle was started waited a few minutes before driving did not know speed all was blank. Stopped after driving around 5 miles to decide, to drive home or call for help. After 20 minutes started vehicle this time dash working drove home with no issues. Will call Dealer Monday to report problem.

About five days ago, my air bag sensors came on and a strange message on the 2022 Tahoe display. It said “ Service Safety Restraint System” needs to be serviced. I received numerous messages from the app and computer system saying something is wrong. I took the Truck in to GMC Brandywine service in Brandywine, MD. I was told they couldn’t fix it and GM knows it’s an issue and may do a recall. I am riding with my son and grandkids in an Unsafe vehicle. I was told something is wrong with the computer. The way it’s communicating the issue but nothing seems right with this truck. I had this truck in service for majority of my ownership for numerous defects. This airbag sensor has had issues in Jan 2022 and now it’s back. They are not fixing these issues and could cost me or my family’s life. I will upload the invoice later. I have to get it out of the truck. I was told GM knows about these issues. But all year it’s been numerous issues and the trucks are not functional.

Starting about 6 months after I received my 2022 Chevy Tahoe Z71 one day when I started the vehicle the instrument cluster was blank (i.e. black and not displaying anything). I turned the vehicle off, then restarted the vehicle and it was still blank. There was not warning or indication this was about to occur. I only needed to go a short distance, so I went to my destination and turned the vehicle off. When I returned to the vehicle (approx 15 minutes later) and started the vehicle the instrument cluster was working again. This occurred another 4 or 5 times over the following 4+/- weeks. I made a service appointment with a Chevy dealer. There were reportedly no codes identifying an issue, but Chevy had a bulletin ("22-na-130"), which I believe was a software update to address various things, including a blank screen, and the vehicle was "reprogrammed". Now a week after this service appointment, the same issue occurred again. Based on my discussions with the Chevy dealer's service department, I have little confidence they can address this issue without Chevy's assistance and based on the process that was described Chevy's assistance for issues such as this may not be addressed expeditiously. As a blank instrument cluster results in the driving not having access to the speed the vehicle is traveling or any other performance metrics of the vehicle I believe this is a serious safety issue. While I have driven the vehicle in this condition, it is only because I was going short distances on local roads where one cannot travel over 25 or 30 MPH. If I was going to be driving on a highway, the vehicle would be unusable. Please investigate this issue, as Chevy's bulletin "22-na-130" and the associated software update has clearly not addressed the issue, and cause Chevy to develop a fix for the issue and recall all impacted vehicles for updating. FYI - I am in the process of scheduling another service appointment. Thank you.

The vehicle has stalled three times since I bought it a week ago. I will be driving and the engine will stall, putting the vehicle into neutral gear. The dashboard will then instruct me to press the power button, and when I do the vehicle restarts and will be in park. It has happened once while driving on the interstate and twice while making turns into oncoming traffic. When I go to accelerate there will be no acceleration, the vehicle will just be in neutral with no warning.
