While driving at night, the vehicle instrument cluster suddenly blacked out. All driver information pertaining to speed, fuel, tachometer, oil pressure and convenience lighting failed. The entire instrument cluster was an unlit black hole. I called GM and they advised there was no reports of this issue and no recalls pertaining to my specific vehicle number. A quick on line Google search revealed service bulletin [XXX].The GM associate I spoke with said they could not confirm or deny that other complaints of this problem had been brought to their attention. She stated that all parts in all their vehicles are vin number specific and that it’s possible I’m an isolated incident. I feel GM Is aware of this dangerous issue and should immediately issue a safety recall before the effected vehicles are involved in fatal crashes after being startled by this blackout event. This is clearly a driver safety issue that GM is not being proactive addressing.

Service brakes, May 19, 2023
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.

Suspension, Apr 14, 2023
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.
Engine, Apr 10, 2023
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.

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.

On three (3) different occasions, I put the SUV in Park and the car engaged, and the "P" lit up as engaged. As I took my foot off the brake, the SUV went into Drive and rolled. This last time, the SUV did this at my kid's school Ater putting it in Park, I took my foot off the brake and turned to get the kids unbuckled, and my foot accidentally pushed the gas pedal. The SUV went into drive on its own and the SUV drove over the sidewalk hitting a rock staircase causing an accident with all 4 kids in my SUV. This is the 3rd time, and I don't know what to do about it. Thankfully there were no kids in front of the SUV.

I have an on going problem with the emissions system on my 2021 Tahoe. The vehicle discharges raw diesel fuel and DEF from the exhaust tail pipe during cold startup. This discharge is overwhelming and is so strong it can be detected by smell from over fifty feet away. In addition to this issue the fumes enter the inside of the vehicle and at times it is so bad you need to open the windows. I believe this problem is unsafe as it poses a fire risk and a CO exposure risk to the vehicle occupants. The vehicle has been in the shop repeatedly for the past eighteen months with various parts replaced. To date none of the repairs have fixed the problem. In February GM issued a statement saying that this is normal operations.
