2017 GMC SIERRA 1500 Complaints

The contact owns a 2017 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle experienced severe transmission shudder and was vibrating while driving up inclines. The vehicle was taken to the local dealer who diagnosed that the transmission torque converter was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 80,000. The VIN was not available.

The incident occurred on [XXX]. My vehicle has 54,571 miles on it. The power brake assist function failed. I was backing into a parking space at a local fast food chain and experienced near brake failure. I had to stand, nearly full body weight pressure, on the brake pedal to get my truck to stop at very slow speed. I, again, backed a short distance of a couple of feet at the most and experienced the same issue when I tried to stop. I placed the vehicle in PARK and turned the engine and ignition key off, thinking the system possibly needed to reset. I started the truck and drove forward, very slowly, to another parking space and applied the brakes. I experienced near total brake failure again. I had my truck into Brogden GMC in Olathe, Kansas on [XXX], for general maintenance and a “brake pressure recall.” I had experienced a slight brake pressure issue on a couple of occasions prior to the recall. After the recall service was performed I did not experience a braking concern for some time. I did experience “soft braking” a couple of times after the recall was performed and attributed it worn brakes. On [XXX], at 50,596 miles, I upgraded my brakes by installing a Power Stop Z36 brake kit with slotted rotors and ceramic pads. I have not had a repeated experience of soft braking or brake failure until the [XXX] incident that I am currently reporting. It appears to me that the earlier recall did not completely address the brake failure issue with my 2017 GMC Sierra 1500 pick-up.

The info system starts to change screens and jump around. We had it on navigate it locked the screen. You couldn't touch anything then. It started messing with the controls on the -Changing it from the speedometer to music and again would not allow you to touch anything calibrated or anything along those lines. After googling it, several vehicles are having the same problem. All around 50000 miles, our vehicle has about 80000 miles.

Transmission temperature sensor has failed. It is available for internal inspection within the transmission pan. Safety has not been in issue, but, apparently it can cause hard shifting when the sensor starts to go bad. You can also easily tell when the sensor is going bad by watching your trans fluid temp needle. It will erratically bounce up and down, sometimes slightly and other times it's big jumps, so you will not be able to tell if the transmission is overheating or running at normal operating temperature. The problem has been confirmed by a local service center. The vehicle/component has not been inspected. There has not been any problems prior to this issue. The check engine light came on 1/24/24 in the evening time. Check engine codes are P0711 & P0700. This is a known issue between 2015-2018 GM vehicle equipped with the 6.2L & 8-speed transmission. There is/was a special warranty number, #N192291660, that qualifies with the 2016 models.

I was driving my truck home from work, when all the sudden the car at a stop sign lurch forward, with the brake applied and was not moving, or I would have hit the car in front of me. Upon, the green light, truck started to shift and go faster, while making a whining noise, at only 26 miles per hour, then, the vehicle, tried to speed up with nothing engaging, and came to a complete stop very aggressively and abruptly, while in traffic, I almost was hit from the sudden stop. Getting to the side of the road, the truck wouldn’t move anymore, and except in rear gear. Called OnStar service and vehicle was towed to the closest GM dealership, about a mile from my house. This was on a Saturday evening, On Monday, the dealer service agent called me, had already diagnosed the problem as a failed 6L80 GM transmission, this was at 930am, asked if I wanted it repaired I said yes. The dealer called back at 3pm that same day and said the transmission had already been repaired. Which to me is a bit surprising as it needed a new transmission, which should take longer. Glad it was fixed so fast. The cost was to be around 6700 dollars. From my knowledge this is a known issue with these transmissions. My concern, is that I could have been in an accident from a known defect in manufacturing that GM knew about and did nothing to address.

Transmission has stalled many times from shifting through 1st and 2nd gear going across divided highways and nearly causing accidents, also it has a very bad shudder and hard shifting.

When I hit the brakes it has no stopping power, hard to push brake pedal and when sitting at a complete stop it has been known to start going even though I have foot on brake.

The contact owns a 2017 GMC Sierra 1500. The contact stated that while coming to a stop at slow speeds, the brake pedal was depressed; however, the brake pedal felt spongey, causing the braking distance to become extended. There were no warning lights illuminated. The contact learned of NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic) and linked the failure to the recall. The dealer was contacted, and it was confirmed the VIN was not included in the recall. The vehicle had not been taken to the dealer. The vehicle had not been diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 60,000.
