Truck has the 8 speed automatic transmission and at times makes a hard shift when pulling out from a stop. Truck currently shudders/shakes at around 1500 to 2000 rpm until the transmission goes into a lower gear. Feels like rumble strips in the road. Truck has only 32,000 miles on it.

EBCM needs to be reprogrammed. Larry Stovesand GMC in Paducah, KY will NOT service my recall because it was closed on 2019, research has shown that this programming may need to be done again. After telling them this info. they are now saying that they will not service my recall because it has a salvaged title. After researching how a salvaged title is still honorable for a free recall service they are now telling me to take it somewhere else.

The contact owns a 2017 GMC Sierra 1500. The contact stated while driving 55 MPH, the vehicle began to shift hard, started shuddering, and lost electrical power.

The trailer brake System sensor keeps going off making the vehicle unbearable to drive. The transmission also jerks when it gets to 7 mph. I've taken the truck to the GMC dealer over 3 times to check the transmission problem and it still jerks. This has been a on going problem since the purchase of the vehicle.

I was driving and my Trailer brake system warning started going off. I ha e never towed anything so not sure why this is happening.

Driving on the highway going approximately 64mph and the traffic lane shifted over and everyone started to slow down and when I went to apply some brake . The pedal got very hard and became very hard to push down effecting my ability to brake properly. This almost caused me to get into an accident and I had to shoot over to the breakdown lane giving me enough time to slow down. My pedal became very hard to push down. This problem continued throughout my travel and service brake assist came on after the fact

My complaint is of the intelilink system in this vehicle. While driving the system would change screens, when turned off would turn itself back on. It would hang up on phone calls, would make all these beeping sounds and change stations on radio. It was very distracting and I feel dangerous in that especially at night as I said would not stay turned off so the beeping and changing of the screen that would make the large(8”) screen go from night mode to day mode and shine into your eyes. When navigating to somewhere system would show that you were in one place, when you were possibly 20 miles from where it would show you to be. Bad because it maybe showing and telling you turn by turn directions and all of a sudden it’s gone. This problem has been diagnosed by a dealer and repaired at a cost of $887.85. Was told that it is a very common repair that they do. Have contacted gm customer service and let them know that I thought a 2017 vehicle with 35000 miles should not have this problem and would like some kind of compensation for the problem and repair

I have carried my vehicle to the dealer 5 different time to report about the hard jerking when accelerating or backing up .First carried it on May 22 2018 and the last time i carried it in was March 2021it had 41083 miles i was told that it normal for the transmission to do that . I should have contacted you after i could not get any satisfaction from the dealership, i have 49800 miles on the truck and it is still doing the same thing. it jerk so hard sometimes it feel like the transmission id going to fall out.I have my paperwork for every time i carried it to the dealership.i just for tired of hearing the same thing I have brought 7 new GMC truck and have never had this problem . I have talk with several owner of 2017 trucks and they said they had the same problem. Will you please investigate . I carried my truck to FLOW of Fayetteville 910 860 9300 for the repair. Thank you.
