2015 CHEVROLET SUBURBAN Complaints

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)

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.

Odometer Fraud. The contact purchased a 2015 Chevrolet Suburban. The contact stated that while attempting to have the vehicle inspected, it was discovered that the catalytic converter was missing, the wires were cut, and a pipe was inserted to muffle the noise. The contact was told that the check engine warning light was turned off and the carbon monoxide was not being cleaned, and that fumes were entering the cabin of the vehicle. The contact also discovered that there was a mileage discrepancy on the vehicle. The vehicle was a dealer sale. At the time of purchase, the mileage was 131,000 and at the time of the inspection, it was discovered that the mileage was approximately 231,000.

The transmission was acting weird and felt like it was revving up and down while going 20-30 mph. After turning into my neighborhood there was a loud clunck like some dropped off the truck and it completely fell out of gear and just rolled to a stop. Shifted it into park, turned the truck off and back on and put it back in drive it went into gear and allowed me to drive to my house but still acted like it was about to drop out of gear completely again. My neighbor has a 2015 Silverado and 2017 Tahoe and both transmissions did the same thing and had to be replaced, all between 100-125k miles. The blind side system constantly goes off when there’s no threat
