2015 CHEVROLET SUBURBAN Complaints

My vehicle started to alert me over and over again about my trailer brake system. It just keeps popping up over and over again and beeps every single time. A lot of GMC and Chevy are having this issue. It could cause hazards when I pull a trailer and the trailer brakes don’t work properly.

While driving, I noticed a significant smell of gas coming from my 2015 Chevrolet Suburban. When I stopped the vehicle, it was even more noticeable. I pulled over and got out of the car only to notice gas pouring (not dripping, more gushing) from under the vehicle between the driver's side door and driver's side passenger door. I was concerned as I had my young child with me and had no way of having someone pick us up. I drove it directly to the mechanic in which they confirmed a leak coming from above the tank and that they would not be able to repair the leak until they dropped the tank. Once dropping the tank, they found a hole in the fuel supply line above the tank due to a poor design and friction from the poor design. There is a service bulletin, 17-NA-304, but it does not protect owners from the cost of the repair. The repair cost was $425.38 despite it being a known issue with GM. This design is incredibly dangerous. Not only is the raw fuel inhalation through the vents a health hazard, it could cause a catastrophic fire as well. I have four children, the reason why we needed to drive a Suburban. The devastation of the risk of this flaw is incredible. This needs to be considered a recall and the cost should be covered by the company, not the owner. I emailed GM's customer service and they stated that nothing could be done because the vehicle was out of warranty.

The trailer breaking system keeps coming on constantly. It comes on randomly while sitting or driving then will keep doing it over and over. It's very distracting and I don't want it to hurt us if it fails etc.

The vehicle component of concern is the braking system. The brake pedal has to be pressed at an unusual rate of pressure to engage the brake system. More concerning is, on several occasions the brakes seem to fail, initiating the ABS system while in fast food lines. This has also occurred while backing up causing the pedal to be jammed to the floor to stop the vehicle. The excessive need for pressure while braking was supposed to be fixed in 2021 by a "simple" recall that simply updated the computer. I had this recall performed, but still have the same braking issues in my 2015 Chevrolet Suburban. I feel that this is a very serious concern and should be addressed. The difference is truly night and day between my wife's vehicle and mine. The braking issue comes with no warnings or alarms. I have had my brakes checked on several occasions to confirm normal brake wear and longevity.

Blind spot detectors failed and shorted out entire vehicle. Caused battery drain and vehicle completely dead had to be flat bedded to dealer Cost of repair 1800$

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 turning at speeds below 20 mph, motor stops lights go out, lights and gauges will come back on and car can be started. This has happened two or three times over the last three months but now only five days apart.

Driving at a slow speed and lost power steering due to faulty power steering module Went into oncoming traffic and drove off road to avoid collision. Recalled 3 years ago for software update but problem happened again and gm would not cover repair

Fuel line running from fuel pump to engine rubs on the frame causing a leak in the fuel line.

Brake pedal got hard and truck didn’t stop until brake pedal got softer, this been happened few occasions.
