What 2020 Chevrolet Tahoe owners say
Engine & cooling
this year vehicle is also part of the engine problem GM is experiencing with the V8 Engines. I purchased this vehicle in January 2024. With less than 40k miles on it. I drove it for approx 2 months and the entire engine seized up. I was told by the Chevy Dealership that GM is aware of the engine problems on these V8 Engines and did not issue a recall. It took GM over 9 weeks to send me a new engine. In which 6 weeks they had me rent a vehicle and then finally allowed the dealership to give me a rental from their lot. I had to wait several weeks to be reimbursed for the rental, and pay my high car payment during this time, without having my vehicle in my possession. I have asked for reimbursement on my car payments, and they denied it. My car seized up while doing 35 MPH on a road near my house thankfully, but it is a danger that they knew about, and did not recall these motors. …
The 6.2L L87 V8 engine in my 2020 Chevrolet Tahoe Premier RST suffered a catastrophic internal component failure while operating. The engine experienced a sudden, severe internal mechanical breakdown involving the crankshaft or connecting rod bearings, completely disabling the powertrain.This failure causes an immediate and dangerous loss of vehicle propulsion, creating a severe safety hazard on public roads.General Motors has already issued Safety Recall N252494001 (NHTSA Campaign 24V924000) for identical L87 engine bearing failures, but has arbitrarily limited the scope to 2021-2024 model years. …
Transmission & drivetrain
The contact owns a 2020 Chevrolet Tahoe. The contact stated that while driving upwards of 80 MPH, the vehicle would violently shake without warning. The vehicle was not taken to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000.
I was starting to accelerate to a higher level of speed onto the highway; 55 mph going up a hill. I was unable to accelerate much as I pushed on the gas, however the RPM's would get higher. while I was at 45 mpg the RPM's were at 3.5. All of sudden my service engine light came on. I knew something was wrong. Turned around took my car back home very slowly, had my husband come look at my car, who has mechanical experience. Transmission fluid is dark and gritty; when its suppose to be a red in color and smooth. I am now needing to replace a transmission in a vehicle that is 5 years old. How is this possible? I have owned the car for 2 years. Why has these not been recalled yet? Why has these not been looked into further? We are paying a lot of money for these vehicles to turn around and put a new transmission, which isn't cheap into a vehicle that is 5 years old. …
Electrical system
The contact owns a 2020 Chevrolet Tahoe. The contact stated that the service trailer brake system warning light illuminated intermittently. The recurrence of the warning light being illuminated had increased mostly while driving at highway speeds. The contact had not taken the vehicle to the dealer to be diagnosed. The vehicle was not repaired. The manufacturer was not made aware of the issue. The approximate failure mileage was 60,000.
On multiple occasions, my car has locked my keys on the INSIDE of the vehicle. I have put things inside my vehicle before leaving and closed all the doors, upon returning, even just a few minutes later, my doors are locked and I am locked out of my vehicle. Additionally, my car is not detecting my remote. I cannot unlock my car with the buttons on the door and need to have my keys in hand for my car to detect the fob. Additionally, if someone opens the door while the car is running but in park, and then closes the door, the Car will beep as if there is no longer a remote detected. This has happened on multiple occasions. I have changed the batteries in the fobs multiple times, switched out my fobs so I was using a different fob and it has happened with both of my fobs.
