Shifting 1st to 2nd and 2nd to 1st is very hard and jolting. It hesitates and doesn't go immediately which could cause an accident.

At 48k miles with all service maintenance performed by GM dealer I experienced a ticking noise and loss of engine power. The vehicle was taken to dealership and I was told it was a lifter problem with no explanation of how or why this has happened. I was without a vehicle for 3 weeks. I picked up the vehicle and was told the vehicle was repaired only to still find the vehicle had hesitation while driving and still had a ticking noise in the engine. I returned the vehicle and am now told the engine needs to be replaced. I was also told that I am responsible for the cost of repairs. I found a class action has been filed against GM for this issue. I have been told that GM does not have a recall issued yet I was told at the dealership they have seen this happen and GM has a Service Technician report on how to fix this issue. At this time my vehicle is sitting at the dealership awaiting a response from GM to see if they will take any responsibility. My truck has been at the dealership since August 7, 2023. I have paid almost $2k and was told I would owe an additional $9300. to replace the engine. I do not have paperwork from the dealership to show service work performed. The dealership has not closed out my ticket however I have paid almost $2k for work performed. The dealership said that they matched the cost I have spent but I have no record of their costs.

Like so many others, I have persistent transmission or drive train problems in my 2017 GMC Sierra. This has been documented on multiple visits and test drives with the dealer where I purchased the vehicle and to another GMC dealer. The first occurrence was after about 4,000 miles. A loud clunk sound occasionally occurs while shifting thru low gears and the transmission shifts very hard. To the point that the transmission hesitates between gears and then jerks me back into the seat. The selling dealer has witnessed this and tried various repairs (supposedly flushed and replaced the fluid, supposedly replaced an unknown computer component, etc). None of this helped. Now the transmission also hesitates and seems to slip during a downshift thru the low gears. The selling dealer finally told me "nothing is wrong with this truck, so don't bring it back again". I assured them that I would never be back, especially when I'm in the market for a new truck. GM should take note of this, also. Online websites show many posts of owners having this issue. And neither the dealers nor GM are even acknowledging a problem, let alone offering a solution. Unfortunately for me and many others, the value of this vehicle is impacted by so many complaints, no action by the federal safety agency and questionable practices by GM and their dealers. Buyers beware!!! The transmission in this truck is junk and you won't receive any assistance from GM or its dealers. The only hope for owners of this truck is for the federal safety agency to step up, launch an investigation and require a recall. This a known issue to owners of this truck, GM, its dealers and the federal safety agency. It's time for all of them to step up and do what's right for consumers.

The contact owns a 2017 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle would hesitate and jerk upon acceleration without warning. The contact also stated that while driving at an unknown speed, the vehicle stalled with the check engine warning light illuminated on the instrument panel. The contact had taken the vehicle to a dealer and was informed that there was a service bulletin that was linked to the failure. Moisture could enter the vehicle through the headlights and cause the electrical and transmission failures the contact was experiencing. The contact was given an estimate for the repair. The contact then called Tameron Buick GMC (27161 US-98, Daphne, AL 36526) and it was stated that they were unaware of such a failure. The manufacturer had yet to be notified of the failure. The failure mileage was approximately 12,000.

My truck shifts very hard between gears, especially 1st to 2nd. Feels like getting rear ended sometimes. It also hesitates daily when backing out of my driveway and putting it from reverse to drive. You don't know when it will actually engage making it dangerous when pulling out into the street. Its definitely an issue with the transmission but no fixes offered from dealer yet.

"have taken my 2017 gmc sierra into the dealership twice for transmission issues, the last time was a month ago. Both times I was told that there wasn't anything wrong but that the transmission software was 're-flashed' and that the transmission would have to 're-learn my driving habits'. My truck is still having problems. While upshifting from 1st to 2nd gear, the transmission sometimes hesitates before it engages and then causes the truck to lunge forward with a huge slam. While downshifting from 2nd to 1st gear, the transmission will make a very noticeable 'clunk'. I'm about to take it back a 3rd time. This is extremely frustrating my bought my truck less than 2 years ago and it only has 25,000 miles."

The vehicle which has under seven hundred miles on it does the following: when I try to accelerate the vehicle starts to misfire, starts to chug and jerk, it starts to hesitate and becomes rough. When I called gmc service department I was told there was a code for this problem #pip5457b but that currently there is no known reason and no known repair and no known computer code to repair the problem. I tried to merge onto the interstate highway and needed to speed up but the truck started to lurch; I nearly got rear ended. I can't drive up a hill in the city or on the interstate and keep up with the flow of traffic because the transmission starts to sputter. My wife and I are afraid to drive this vehicle. We just paid nearly $49,000 for this gmc sierra 2017 and only owned it for one week when this started to happen. It does this all the time. Very dangerous!
