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.

- Lakewood Ranch, FL, USA

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.

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.
