2021 CHEVROLET TAHOE Complaints

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.

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.

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.

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.

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.

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!
