2021 CHEVROLET TAHOE Complaints

The contact owns a 2021 Chevrolet Tahoe. The contact stated that after coming to a stop, upon depressing the accelerator, the vehicle experienced phantom braking. The contact stated that the Forward Collision Avoidance warning light illuminated, and the vehicle inadvertently stopped with no vehicles or objects nearby. The contact stated that the Forward Collision Avoidance system was deactivated to prevent the failure from recurring. The dealer was notified of the failure, but the vehicle was not taken to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 8,500.

I started my vehicle and I pulled it out of my garage. Whenever I went to push the brakes down before pulling out of my driveway, it seemed like the brake pedal was higher than it usually is because my shoe caught the edge of the peddle due to where I am used to feeling the top end of it to decompress it. sometimes I contribute that that to the type of footwear that I have on but I was wearing the same shoes I had worn driving the vehicle only 1 hour ago. I was not sure why that was but I kept pulling out of the driveway (maybe something was stuck to the bottom of my shoe?) I continued to pull out and drove up my road to the next intersection where there were vehicles in front and behind me at that point. As I approached the intersection, slowing down to 25ish mph, I decompressed my brake peddle and all sorts of messages about brake failure started to appear in my control center and the peddle went all the way to the floor without fully stopping the vehicle. It seemed to be able to slow the vehicle down but very so slightly. Luckily, the people ahead of me continued to drive forward and the road was going uphill so the vehicle slowed on its own due to the terrain, at which time, I advised my daughter who was in the backseat to hold on that I needed to put the car in Park while we were still moving slightly. We were slowed to about 2mph and I put the car in Park. I looked down at the brake peddle and there was a fliud that had leaked out on top my all weather floor mats (non absorbent). Luckily, we were not involved in a collision but it was only due to the terrain and the fact the people in front of me continued to drive forward. Otherwise, we would have hit them from behind.

My Tahoe was running fine and then when I shut it off and returned 30 minutes later it would not start. I had it towed to a nearby dealership and I was told that several similar incidents have happened with my make and model where the fuel pump control module went bad. A technician replaced the module while it was in the tow truck so it could be unloaded and it started up. I was told that GM is aware of the issue and I have not heard about it and believe there should be a recall to replace these faulty modules.

I was driving the vehicle and it suddenly lost power - going from 55 MPH down to 0 then the engine just stopped. No warning lights went off, no stalling, no engine noise- completely lost power. Would not start after that for 20 minutes. Started after 20 minutes- and ran fine -like nothing happened. Had it towed to dealership where they diagnosed the problem as electrical. Two weeks later still waiting for the part. Dealer says it could be up to 3 months before they could locate the part.

water leaking in from the roof area. I heard water above me, then after applying the brakes water came pouring in through the LED lights, seat belts, and other areas mostly on the passenger side of the vehicle. After pulling panels and looking, water was dripping down into the car getting airbags wet, the fuse panel, seat belts are soaked, carpet, and water inside LEDs and dripping on other electronics. Dealership unable to locate leak at this time and is a continuing problem.

Fuel pump control module diagnosed by the Chevrolet dealer in Iowa City, IA (Billion Chevy). We were on the interstate when the vehicle decelerated rapidly while passing a semi tractor trailer. I was able to control the vehicle and move to the right lane after the semi trailer went by and other cars moved back quickly. No warning light until the incident.

I’ve been dealing with an alignment issue since last June when I took in my 2021 Tahoe z71 with air ride suspension. It’s chewed up the stock tires at just 25,000 miles. It’s came out of alignment 3-4 times since then and Chevrolet is doing nothing about it. I’ve spoke with others that have the same vehicle and the same problem. I just purchased tires for $1,100 just over a month ago and I checked the alignment last week and it was out again after City Chevrolet fixed it on January 17th of 23.

I bought the vehicle (a Chevy Tahoe) brand new in 2021. After 7,000 miles the lifter in the motor broke. The top of the motor had to be rebuilt to accommodate a new lifter. Now, with 24,000 miles on the vehicle, another lifter just broke, so the motor has to be taken apart again. I am certain GM knows about this problem, as (the lifter issue) it is all over the internet, but GM will not issue a recall of the defective lifters. I would be very interested in joining a class action law suit to force GM to recall the defective (lifter) parts. In both instances when the lifters broke, there is no warning! The engine looses power and the vehicle "bucks and shakes". It is just a matter of time before this issues causes sever bodily harm because of this massive engine failure. I have all of the repair documentation.

Vehicle is displaying service safety restraint system error message which may affect airbag deployment. Dealer advised problem from GM with a harness being too short under seat and seat adjustment can disconnect SRS system which could fail during an accident. Advised no recall but repair parts were not currently available.

My tahoe has shut off several times. I am sometimes at a red light and it shuts off and won't turn on or itll eventually turn off but it has a ton of errors on the screen. This has happened about 6 times. Today, April 6th, it wouldn't even start. It has started at the dealership but the screens are blacked out. Also the back hatch is not working as well and it randomly happened. I just purchased this vehicle in September of 2022. And it only has about 40k miles on it. The first time it shut off on me it had less than 40k miles.
