2015 Chevrolet Silverado 1500 brakes problems

Filed Sep 29, 2026 · Brakes, Transmission · TN

At 124,000, the transmission started slipping and not grabbing gears. Coleman Taylor Transmissions ended up having to do a full rebuild which costs about $4000. At around 20,000 miles, the vehicle started to shutter going 45 mph. The vehicle still does shake violently at 62-75 mph causing a safety concern. The brakes wont go if Ive been standing still for a long time like in a drive through or backing down a boat ramp. You have to stand on the brakes with both feet to get the vehicle to stop and thats only going 5 mph. We still own this vehicle and still have issues with it.

When applying brakes at low speeds the brakes are unresponsive they sound rough and the vehicle does not come to a stop it skids forward, and an electric low whine occurs. This doesn't happen everytime. I took it in for Carvanas 30 day warranty and was told its because I drove it down the mountain grade while applying brakes and they didnt find anything wrong with the brake thus wouldn't be covered. Been seeing this vacuum issue with the brakes on this particular issue and seeing if I can get this resolved.

I test drove a 2026 Silverado 1500 at Hanania Chevrolet in Saint Augustine Florida on [XXX]. Before the test drive, I advised the salesperson in the rear seat that the Service Brake Assist light was on at the instrument panel. He advised that the light needed to be reset and he would have it taken care of. I returned to the showroom to complete the required paper work and the vehicle was cleaned and returned in front of the showroom. I drove the vehicle on [XXX] after driving a short distance the "Service Brake Assist" light again came on. I notified the service department on 6/1/2026 and drove the vehicle back to the dealership. The service advisor indicated he was going to have his best Technician repair the vehicle. I arrived at12:33 and the vehicle was completed at 12:56 PM I drove the vehicle back to my home without any issues. I left my home on [XXX] and as I turned onto the Interstate Highway, the light came on once again. After researching this issue, it is not advisable to drive the vehicle as the Antilock Braking System will not operate correctly. This vehicle should NOT have been available for any prospective customer to drive on the highway until the issue is corrected. The sales person should have verified that the brake issue was properly repaired before offering anyone a road test in the vehicle. The vehicle is currently at the Dealership.

Driving the truck, a nut fell against my foot. I pulled over and looked underneath to where this Nut could have come from. I realized that the brake pedal was very loose. I did a Google search to see what break pedal Nut could have loosened and Fallen off. I identified that there was a recall for the brake pedal pivot nut on these trucks. From that, I looked up to that section and found that the nut did indeed come from that part. I called the local Chevrolet dealership and they informed me that my VIN number was not part of that recall list. It is obvious that General Motors left the numbers off of that recall for vehicles that are still being affected by that problem. I called General Motors customer service and spoke to Brandy at customer service and she was not willing to help and only told me to contact this government agency. In order to prevent fatalities of innocent lives, I am reporting this.

I am the original owner of a 2015 chevrolet silverado 1500. The vehicle's brake vacuum pump has failed, resulting in a sudden, significant loss of power braking assist. This requires excessive pedal force to stop the vehicle, creating an immediate safety hazard and increasing the risk of a crash. General Motors previously issued special coverage adjustment N192210240 ( or N182202780 ) to address this specific component failure, extending warranty coverage to 10 years or 150,000 miles. I never received notification of this coverage or the potential safety defect. The dealership has confirmed the vacuum pump failure but denied coverage because the 10- year window has recently expired. I contacted GM Corporate on 12/16/2025 and 12/17/ 2025 they declined GoodWill Assistance. I believe it is unreasonable to deny coverage for a know safety defect on a vehicle owned by the original purchaser who was never properly notified of the extension on N182202780.
