ELECTRICAL SYSTEM, STEERING
I recently purchased this vehicle about five months ago. I took it to Riverside Chevrolet to get a diagnostic on it because my steering wheel is locked all the lights on the dashboard are on in the vehicle is not drivable almost a month and a half of Riverside Chevrolet and they could not get a diagnostic on it. Apparently the technicians there were not able to figure out what’s wrong with it. The vehicle is not drivable and it is a safety hazard

ELECTRICAL SYSTEM, STEERING, EXTERIOR LIGHTING
The 2015 Chevrolet Tahoe seems to be known for thermostat failure. My thermostat gauge while driving would drop from 210 to 160 and stay pinned on 160 and the fans would turn on. I was told by an auto body shop that it seemed to be electric issues. I also had a wire under the car catch fire and the auto body shop said that is why my standing lights would not work in the rear but my brake lights would work. It’s very dangerous that the electrical failure caused a fire to start under the car. Then, I ran into another issue just this week where the vehicle has a cracked AC condenser and is slowly losing coolant. It’s a manufacturing issue because all of them seem to crack and we’re not made with a proper seal. Another electrical issue I have is when I turn the wheel all the way to the left or right, even when the key is in and engine is on, the engine will shut off. The car completely shuts off and then I have to turn the key to the off position and then it will turn right back on. The steering wheel is also losing power steering and gets very tight when I have to make a turn. The fuses for my radio are blown and when you put new ones in, it blows immediately and doesn’t turn on. I have MANY issues with this vehicle and it’s obviously a manufacturer issue. This is not ok for a vehicle to all around have such horrible electrical issues. I have had issues driving over a pothole and I lose my radio screen or my whole dash screen and then the dealer and auto body shops say the electrical work is too in depth for them.

SUSPENSION
I have a 2015 Chevy Tahoe LTZ I bought used 10/12/2024 with 100,000 miles on it. I purchased it from a family member that took great care of it. Always garaged and kept up with all the maintenance's regularly. In March of 2025, we noticed how uncomfortable and terribly bumpy it was riding. I looked it up and discovered that many people with this "Magnetic Ride Control" installed on many other vehicles had to replace them. I thought for sure this would have a recall. And to my disappointment, it was not a recall. I had to pay over $3000 dollars to repair this, which I don't have. Can you please look into this and make the manufacture or someone accountable for such a terrible design. Thank you bumpy it was riding.

POWER TRAIN
Transmission delays in shifts. Whine coming from transmission as well. New torque converter and thermal bypass installed with new transmission fluid and filter. Truck was diagnosed and it’s okay in Chevrolets computers. This is a scary and unsafe way of feeling scared if transmission will fail.
