2015 Chevrolet Suburban Problems

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.

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.

Hello, While driving my Chevy suburban last week as I was pumping gas with my two year old son in the back seat. I saw smoke leaking and rolling out from the bottom of my vehicle. I had shift the vehicle off and inspected thoroughly. I couldn’t see and understand where this was coming from. It wasn’t the engine block and no check engine lights had come on. So I let the vehicle cool and started her up. No issue until I was a mile or two from my family summer rental and all of a sudden the vehicle felt as though it slipped out of gear. I was left without any power and realized I was smoking again. I pulled or what I would call drifted to the break down lane and pulled my little man out of the vehicle. This happened on Saturday and after almost a week in the shop, the dealership sprung me a nice $5200 price for a transmission. I am now looking and seeing two different recalls for this vehicle. Ironically the these two issues look exactly like the two recalls they have for the power train.

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.

The Day Light Running Lights will not go off preventing the low beam light from lighting properly. 08/21/2025

Headlight assembly leaks and retains significant amounts of water resembling a half filled fish tank. This causes the bulbs to burn out or corrode the light power supply leaving you with no headlights! This is a very common problem across many GM platforms. I am surprised the Government regulators have allowed a safety problem this wide spread and known to continue unaddressed.

When the air temperature is in the single digits the seat belt buckles do not latch or unlatch when pulled on. I thought my seat belt was latch no warning sounds indicating that it was not latch, but when i went to reach for something on my dash it unbuckled. When temperature is above 9F degrees buckles work fine. Both driver and passager side seat belt buckles do not work properly when it is cold out. Just wondering if others have brought this up.

I HAVE JUST OVER 84000 MILES ON MY SUBURBAN. I HAVE HAD TO REPLACE THE A/C CONDENSER DUE TO FAILURE IN A WELD AND NOW HAVE TO REPLACE ALL FOUR STRUTS AS THEY HAVE NOW FAILED. I ALSO HAVE PART OF THE HEATED SEATS NOT WORKING AS WELL AS SENSORS THAT NEED TO BE "UPDATED" ALL THE TIME. I FIND IT RIDICULOUS THAT CHEVROLET WILL NOT STAND BEHIND ITS PRODUCT, ESPECIALLY WHEN SO MANY PEOPLE ARE HAVING ISSUES WITH THE SAME PARTS OF THE VEHICLE.
