FUEL/PROPULSION SYSTEM
Driving long distance from Florida to New York and in VA, experienced a check engine light after fueling. Vehicle started, stalled and trembling excessively. It was taken to the Chevrolet dealership across from the gas station (total luck). It was diagnosed after 1 day in the shop that all 8 fuel injectors and the two fuel rails were corroded and had snapped upon inspection.( photos were sent to me). Vehicle could not be driven. If stall would have occurred while driving on the interstate at speed of 70 -75 mph, the potential for a major car accident with other fast moving vehicles was totally possible. I had to remain in a hotel for 3 days as the dealer had indicated that the parts were on back order because this was a recurring issue in the Tahoe/Suburban/Silverado L87 6.2 HP engine. I rented a vehicle to drive back to NY and got my truck back 14 days later after paying for it ($4600) as GM stated that they could not honor the 5 year/60K warranty despite my truck having 52, 182 miles and less then 5 years because they went by the build date of the vehicle which was March 14, 2020 to March 14, 2025, not the calendar year.

FUEL/PROPULSION SYSTEM
Check engine light illuminated then went off and came back on after another drive cycle. Vehicle began to idle rough and experienced hard shifting and acceleration hesitation. I checked the oil and noticed a fuel odor smell on the dip stick and the oil appeared thin. Upon mechanic inspection they found a malfunctioning high pressure fuel pump. This part was recalled on other vehicles of the same model year due to bad welds. This could have resulted in fire if left unchecked.

Zero warnings. Driving one day and the vehicle started shaking and running very hard even when just in idle. Dealership has determined engine failure, due to piston one failing and braking off into engine. Car has had routine oil changes and maintenance. Has not been inspected by manufacturer. GM is not assisting.

We are concerned that the transmission recall should be including ALL 2020 Tahoe’s. We were driving at 55 MPH and our RPM suddenly excelled and the vehicle felt like it was in neutral. This happened several times in a short distance. When we arrived home and tried to put in reverse it hesitated to move and then finally engaged. Getting it into dealership this week.

ENGINE
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. I could have been driving over 65 miles on the highway and this could have happened, causing extreme danger to me and my children.

I was at a red light and when I tried to take off the RPMs reeved up and my car would not move so I turned it off, opened and shut my door, restarted my car and it would move 100yds if that, then the RPMs shot up again (acted like it couldn’t shift out of first gear). Car has 101,647 miles, was serviced on time, no issues before and no warning lights on the dash came on before or after the issue happened. Car has not been repaired yet and still no lights on the dash.

While driving, the vehicle's RPM's accelerated quickly and then the vehicle stopped in the middle of the road and would not move. I could not even get it to the side of the road to be out of traffic. All regular maintenance has been performed. The mileage is almost 100,000, but not there yet. This could have been a very dangerous situation as I was heading to an interstate highway. No warning lamps ever lit up and no strange sounds or vibrations ever came from the vehicle. This happened suddenly. No warning whatsoever. The vehicle is being repaired today. The transmission is being replaced at a cost of $5500.00.

ELECTRICAL SYSTEM
I writing to complain about the "Trailer Brake" warning light that suddenly appeared on my 2020 Chevrolet Tahoe. After visiting the internet I then saw other complaints about the module on the dash for the trailer brake adjustment having repeated complaints. I have never used the 2020 Chevy Tahoe to tow a trailer that had its own braking system. The only thing I have towed was a small U-Haul Trailer. All the complaints about this module is the same: Warning light on the dash display. If so many other Chevy Tahoe owners have complained ... what hasn't there been a recall for this repeated electrical malfunction?

TIRES:SIDEWALL, TIRES:BEAD, TIRES
Brand new set of tires. Less than 100 miles on them. During a left turn at roughly 15-25 mph the entire tire separated from the rim on the rear passenger wheel. The tire is in a secure location and can be inspected if needed. This led to an accident. There were no warning indicators such as low pressure indicators. The low pressure indicator came on after the tire came off the rim. The car went from make a 90 degree turn to making a 45 degree turn and cause my SUV to smash into a house. Tire size was 285/45/R22.
