FUEL/PROPULSION SYSTEM
I was driving down a busy road with my toddler in the car when the car just stopped. Went from traveling 40 mph to a complete standstill. Dead, in the middle of the road. No warning lights or signals at all. Could not get the car in neutral. Wheels locked up and not able to shift to neutral without the car being on, which was not happening. Had to get the car towed to the dealer. The tow truck driver had to drag the car on to the truck. No getting the car in neutral at all. Dealer diagnosed the problem as the fuel pump control module, which after researching is a major problem for this make/model/year. Should most definitely be a recall that has to be remedied by the manufacturer as this is not safe at all. Could have easily been hit due to traveling at a normal speed to stopping so suddenly. Then on top of it, not being able to get in to neutral to get to a safe location out of traffic.

FUEL/PROPULSION SYSTEM
My Tahoe 2021 RST has been leaking what smells like diesel. This goes all the way back only months after I bought it new. This came and went sometimes once a week sometimes once a month. And for the next few years many months I could smell it but no leaks but in the last 10 days the diesel leak has been massive. It leaks from under the engine and if the hood is opened the diesel leak is all over the engine. The smell has been noxious sunce the beginning. Over the years the smell was there off and on. Comes and goes. But the last few months it has been everyday. Apparently the shop had fixed and replaced some parts several weeks ago but the smell of diesel never went away. Now it is in the dealer shop again. Because the fuel leak is too massive and the smell is ever worst.

POWER TRAIN, ENGINE
* Sudden Catastrophic Engine Failure. * The car lost power in the middle of a high traffic, very dark country road, forcing her to stay in the middle of the (undivided) road in the dark hoping cars didn't slam into her. A Collin County Sheriff was dispatched to keep her safe until the tow truck arrived almost two hours later." * The vehicle was towed to a dealer where they confirmed that the torque converter, valves, lifters had failed. Dealer didn't disclose that there was any issues for these engines, which there is. It's a 6.2L V8 Tahoe High Country. * It has only been inspected by the dealer, not the manufacturer, police, insurance representatives, etc... * The vehicle indicated a traction control problem, then the engine light came on, and then the engine failed followed by loss of power. All happened in rapid succession WITH NO OPPORTUNITY FOR THE DRIVER TO GET TO A SAFE LOCATION. * There was no warning or other symptoms preceding this. The vehicle has always been faithfully serviced at Chevy dealerships consistent with the manufacturers recommendations.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS, SERVICE BRAKES
While driving on I-90 in Montana on a clear, sunny day at the posted speed limit of 80 miles per hour for one hour, the vehicle began making knocking noises then, all of a sudden lost power. Upon inspection at the nearest GM dealership service department in Butte, MT, I was told something within the engine broke. I have attached an emailed repair bid from the GM service department and have copied and pasted the highlights here: -Engine, Lines, Radiator, Water Pump, and Tune up ($14,400.00) -Cam, Lifters, Lines, Radiator, Water Pump, and Tune Up ($11,400.00) -Master Cylinder/EBCM ($3,310.00) Previous to the incident, all recommended and routine maintenance was performed at intervals recommended by GM and by GM dealership service departments and/or the Valvoline Oil Change location in Missoula, Montana. The odometer reading was between 95,000 and 96,000 miles at the time of incident.

FUEL/PROPULSION SYSTEM
I noticed the vehicle had intermittent hesitation while accelerating to merge onto a freeway on the previous evening. We drove straight home from there and the next morning as we prepared to go somewhere the vehicle lost power in our driveway and now will not start. Trouble code P129F Fault code is being thrown. This seems to be related to the GM issued TSB PIP5964 and the also GM Recall N252516900 . However, GM is denying that our VIN should be affected. I'm concerned that they're not aware of or intentionally excluding vehicles that could have this issue. Had we lost power while in motion, like on a busy freeway or crossing an intersection, this could have been catastrophic.

EXTERIOR LIGHTING
I recently purchased this vehicle from a dealer in FL, but unknown to me at the time was the headlight adjuster on driver side was broken, causing the aim to drop to the bottom limit. This causes only the passenger side light to illuminate the road. I discovered this problem about a week after purchase. The dealer does not seem to be willing to correct this issue. This is a common problem for these vehicles, verified with online search's. The fix is to replace the entire headlight housing which is quite expensive, and then the labor to remove and replace the front bumper assembly.

FUEL/PROPULSION SYSTEM, POWER TRAIN, UNKNOWN OR OTHER
This vehicle has experienced multiple substantial defects, several of which directly endangered my family, including an infant, and rendered the vehicle unsafe and inoperable for extended periods despite warranty repairs. Summary of defects and failures: 1.Electronic door locking failure The vehicle experienced an electronic malfunction that caused the doors to randomly lock, resulting in my infant being locked inside the vehicle when we exited. This wiring defect was later repaired under warranty but represents a serious safety failure. 2.Fuel pump recall and highway breakdown While driving my family of six on a major highway over an hour from home, the recalled fuel pump failed while in motion, leaving us stranded on the side of the highway. We were forced to arrange an Uber for transportation. This incident placed my family in a dangerous situation and constitutes a major safety-related defect. 3.Transmission failure and extended inoperability The vehicle suffered a transmission failure that rendered it unsafe and inoperable. The dealership required over one week to schedule service and more than two additional weeks before the vehicle was inspected and repaired. The vehicle was out of safe driving condition for approximately one month. Upon return, the vehicle experienced additional failures, including a dead battery. 4.Known poor design defect – rear entertainment screens The rear entertainment system screens cracked due to a widely known poor design and placement issue, unrelated to misuse. 5.Rear headrest internal mechanism failure The internal mechanism of a rear headrest failed and requires replacement, further demonstrating ongoing quality and safety concerns. Due to the number, severity, and safety-related nature of these defects—combined with cumulative downtime exceeding 30 days—I have lost all confidence in this vehicle. I no longer consider it safe or reliable for transporting my family.

EXTERIOR LIGHTING
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.

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.

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.

FUEL/PROPULSION SYSTEM, ENGINE
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.
