I was driving on the highway at approximately 35mph when I noticed there was no response from the accelerator. I shifted the vehicle into neutral and coasted onto a side road and call OnStar for assistance. The dashboard indicator said to restart engine. I attempted to restart, but the engine would crank but not turn over (start). The vehicle was towed to the dealership where the fuel pump assembly was found to have failed and need replacement.

Having to replace the radiator due to it leaking around a plastic connection to metal. Was told by the dealership this has an updated part from GM due to it being a known issue.

My Tahoe was making a loud noise, I took it to the dealer to look at it and they said I need to replace the rear driveshaft to the tune of $4000. I don't have $4000 to spend on this. This Tahoe is only 4 years old and was supposed to drive us to Minnesota next week for Christmas and now that is not possible. This is a known issue and a recall, but my VIN not included in that recall. How can this happen - you know it is a known issue in these cars! Power train Recall date 2022-01-27 Recall no. 22V036000 General Motors, LLC (GM) is recalling certain 2021 GMC Yukon, Yukon XL, Cadillac Escalade, Escalade ESV, Chevrolet Suburban, and Chevrolet Tahoe vehicles.

Issue related to the rear-differential fluid, TSB 21-NA-028. Its a known issue where the rear differential make moan/chatter noises on turning (including at low speeds). Dealers are instructed to service/replace the rear differential fluid and perform procedures to address clutch pack chatter. It is such an issue, the fluid to remedy this is on back order!

2021 Tahoe Z71 with 70000 miles making a roaring and whining noise on reverse and turning, especially when cold. Took to shop and they changed the rear differential fluid. Now its worse. Needs a whole new rear end. This veicle is 4 years old and does not tow or use four wheel drive. The shop said there has been so many complaints and services on the same issue. Why is there not a recall on this yet? We spend $70,000 and up and expect a more quality vehicle without having to spend $4000 dollars on repairs.

vehicle infotainment system will randomly "restart" or shut off completely when vehicle is being drove, but will still be playing music also all time and temperature (outside temp) will freeze when this happens. it also make the battery drain when this happens. the only way to get the screen to come back on weve tried is to disconnect battery. weve replaced the battery, weve had a chevy dealership look into it. no one can figure out what is happening. Now it is happening more and more. we also do not receive updates anymore to the infotainment system. the dealership had to manually do it a year ago. also will not keep our proifile signed in at all. always says were stuck in guest mode. says we have full storage when there is not any apps downloaded.

Received an Over-the-Air update that rendered my vehicle unless. My vehicle would no longer start, or power on, or power on in accessory mode. It was stuck in Park, the electronic Parking Brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the Parking Brake. The battery was fully charged. I also started receiving messages through my Chevrolet APP that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. GM could not find any

Car stalled while driving on the highway, no warning, car became unresponsive and we almost had an accident attempting to move car off the highway. This was an extreme safety risk. Car was dead, unable to start. Towed car to dealership, told it was the fuel control module that was not working.

On November 9th, 2022 my wife was returning from the store when our Tahoe lost power and the engine shut off. She was able to pull off the highway onto a side street prior to the engine shutting off. I met her at that spot to see what was going on with the vehicle. The car was parked on a slight hill and after checking the oil and other fluids I could not see an issue with the car and the car would still not start. I was able to tow the car to a flat spot and checked the fluids again. After about 45 minutes the car did restart with the check engine light on. We were able to get the vehicle to an auto shop about a 1/4 mile down the road where they were able to hook up their reader and see what the check engine light was for. A code of P129F came up which is the fuel pump module, pictures at

As many have already complained, the headlight adjuster screw for the drivers side of the headlights of the vehicle always break or get stripped out even at low mileage, causing the headlight of the drivers side to point down onto the road and being unable to illuminate anything past the very front of the vehicle at night. This is a serious hazard that is not possible to fix or adjust without a large bill at the dealership. The drivers side headlight is pointed down and me myself, has resorted to adjusting the passenger side headlight to point up to compensate for this issue. This is causing many safety issues as I cannot see anything past 1-2 feet from the front.

The REAR end of the truck needs to be repair. The dealership says multiple people have needed to order the rear end.

GM decided to use Brembo brand brake pads and rotors on the front of the newly redesigned 2021 PPV Tahoe. I have 16 of these vehicles in my fleet at the Sheriff’s Office and everyone one of them squeals really loudly when the brakes are applied. I now have one Tahoe out of service due to the fact it needs pads and rotors on all four corners. The main concern is there are no rotors available anywhere for these units.

Air bags did not deploy after significant frontal damage. No warning that the air bag sensor was bad.
