This has almost caused us to get in an accident several times now. While driving and taking a curve or while gradually turning, the power steering failed. The steering wheel was extremely difficult to turn, and my wife could barely turn it. The message “Steering Assist Reduced – Drive with Care” was displayed. When we pulled over and turned off the engine, and then later re-started the Suburban, the power steering worked again. The dealer conducted a diagnostic on it and could not find the problem at first. They later said the Power Steering Gear needed to be replaced. This is a very dangerous problem.

I experienced a serious brake failure in my 2015 Chevrolet Suburban with 112,500 miles that nearly resulted in a collision. After approximately 90 minutes of driving, I pulled into a parking lot and attempted to stop. Without warning lights or prior symptoms, the brake pedal suddenly became extremely hard to press, and the vehicle nearly failed to stop. I had to stomp on the brake pedal to stop. The same dangerous condition occurred while reversing into a parking space. This created a serious risk of injury to myself and others. The problem appeared primarily at low speeds. After sitting for several hours, the brakes seemed normal again. This intermittent failure is especially dangerous because it occurs without warning. A GM dealership inspected the vehicle and confirmed: "Vacuum pump has failed internally causing a stiff pedal at times when pumping brakes. Pump can't build vacuum fast enough to keep up with demand to fill brake booster." The failed component is available for inspection. I discovered GM Special Coverage N182202780 addresses this vacuum pump failure. However, GM refused assistance because my vehicle exceeded the 10-year coverage period, despite having only 112,500 miles. In approximately 2020, I had a GM braking safety recall performed. The dealership reprogrammed the vehicle and installed a thicker brake pedal pad rather than replacing the vacuum pump. Despite this previous recall repair, I experienced the dangerous braking condition. I believe this is a serious safety defect, not simply a warranty issue. A critical braking component should not fail without warning, making the vehicle extremely difficult to stop. I request that NHTSA investigate whether the previous recall remedy was adequate and whether GM's special coverage should be expanded into a safety recall regardless of vehicle age.

When coming to a stop or backing from my inclined driveway the foot brake requires a hard push because it seems to lock up. I couldn't stop when braking. The problem is recurring. It has not been inspected for this recurring problem and no lights or warning signal appears on the dashboard.

Fuel line leak caused by design flaw in which line plastic fuel feed line (GM part #84200271) is installed too close to the undercarriage, causing it to rub against the frame due to vibration and wear a pinhole. This is known by gm in service bulletin Service Bulletin 17-NA-304. This is a fuel leak, that can causes significant fire danger to people, property, and nature. Eventually putting first responders at risk. Also the environmental risk of continuous leaking fuel. Luckily, I could smell it before anything bad happened. But if GM knows about this issue, it’s big enough they should do something about it and so should the NHTSA.

When our new mechanic was checking over the car, he and his other mechanic both noticed that there was an increased brake pedal effort even though the brakes were in ok condition. Every time I’ve had the car serviced I have them check the brakes because they feel off. The car stops and the brakes check out with previous mechanics but something doesn’t feel right. Our new mechanic then gave me a recall bulletin from GM N192268490 and said he thinks our car is experiencing this issue. The recall was attached to our VIN when the mechanic pulled it up but when we called the dealer and checked the NHTSA website, my VIN number was apparently not part of the recall. I am writing to state that I believe my car may be experiencing the issue stated in the recall bulletin as per my mechanic’s findings. Attached is a copy of the recall bulletin given to us by our mechanic. Please advise.

Pulling off from a stop sign on a hill, the car wouldn't accelerate and rolled back hitting a pedestrian and then jerked forward aggressively burning rubber on the tires. I smell the transmission burning. Luckily the lady didn't want to press charges.

On at or about November 1, 2025, I experienced a sudden loss of power steering. I was backing up in a parking and experienced a complete power steering failure. Since that date, it has failed multiple times. There was a recall on the EPS Module in 2015. I have contacted a dealer, they could not find a recall for any power steering issues, when there clearly has been. If there has been a recall for the steering of the same model and make and year, and is clearly a SAFETY ISSUE, this recall in 2015 should cover my vehicle also. I was under the assumption that my vehicle was low on power steering fluid. Proceed to look for power steering pump to check fluid level, no reservoir! Start to investigate, find out I have an Electric Power Assist Motor, and an electric module that can not be replaced when it fails, the entire assembly has to be replaced, no way to replace fluid! I’m in the process of getting an estimate of repair as of 11/25/ 2025. There was no indication of any kind, of possibly failure! There is no data stored in the computer indicating any failure, electrical or otherwise!

The braking system on my 2015 Chevy Suburban LTZ failed at slow speeds in a parking lot. I have replicated the issue in both forward and reverse. My family's safety was put at risk in that while backing up out of a parking spot the brakes failed completely and I had to push extremely hard on the brake to get the vehicle to stop. That same behavior occurred while pulling forward into a parking spot, almost hitting the car in front of me. I took the vehicle into a Chevrolet dealer today indicating the symptoms and they said there was no recall attached to my VIN. This exact same behavior in my vehicle is described in [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns 2015 Chevrolet Suburban. The contact stated that while inspecting the vehicle, the contact saw rust on the frame and saw horizontal lines that became progressively worse over time. A dealer was contacted. The vehicle was taken to the dealer, and the contact was informed that wax could be added to the rust spot and that the repair would be out-of-pocket because the failure was not under warranty. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 19-NA-255 (Wax Coating on Frame Peeling, Metal Shows Corrosion/Rusting); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 114,481.

If I pull up to a parking spot and I’m slowly creeping into the spot, say at a popular supermarket, and slowing down the brake pedal stiffens up and it’s almost impossible to press. I feel like my truck may not stop. If I’m on a slight incline and in a line behind another vehicle, I’ve noticed the brake pedal stiffens up then as well. Awhile ago I thought there was a recall for this for my truck and it was something about the vacuum in the brake pedal. This is a super problem. I have five kids and we are on the road a lot. This has been happening a lot but most recently would be today.
