2020 Chevrolet Tahoe

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.

My 2020 Tahoe stabilitrak has gone off approximately 5 times over the past 2 months April and May of 2025 in one incident my vehicle did turn off all incidents were at low speeds less than 5 MPH. Four of the incidents the stabilitrak light turned on and an audible beep, I also lost power to my steering and breaks. When I had the oil change the service Tec at the dealer stated they can not test it unless the light WAS on? Has anyone reported or experiences this issues What can be done to fix this issue. Please email me at [XXX] if you have any questions or helpful hints. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.
