general problems of the 2016 GMC Sierra

Apparently, the 8 speed automatic transmission has issues with wiring harness and hard shifting which the manufacturer has 18 service bulletins out on yet still will not recall and fix problems. Also the brake system is faulty and unsafe it loses pressure and even braking at various speeds. After taking it to the dealership they can not figure out why and say it is various parts and should be recalled but it is not as of yet. Gm knows of these issues and the 1000s of dollars customers have to pay for these repairs. This is wrong and needs to be rectified.

Truck lurched uncontrolled for several feet when placed in reverse gear.

The truck has a horrible vibration from around 45 mph and up. Have test drove other 2016 GMC Sierras with same issue. Have taken it back to the Dodge dealership we bought it from and they said it should be a recall.

The contact owns a 2016 GMC Sierra. The contact stated that after starting the vehicle and shifting to drive (d) the vehicle was hesitating and then would lunge forward as she depressed the accelerator. The contact stated that the vehicle was also lunging when she was depressing the brake pedal as the vehicle was down shifting. The contact stated no warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the transmission needed to be flushed. The vehicle was not repaired. The contact stated that the failure was reoccurring. The contact stated that the check engine light had recently illuminated. The manufacturer was informed of the failure. The failure mileage was approximately 165,000.

Truck lurches forward unexpectedly during slow stops such as when approaching a barrier to park, a gate, or pedestrian crossing. As the transmission downshifts, the torque increase causes the brake pressure being applied to become insufficient to stop the vehicle causing it to lurch forward up to six feet. During accelleration while highway driving the transmission may unexpectedly downshift to an inappropriate gear causing the engine rev limiter to engage and reducing power unexpectedly when it should be increasing.

Since I've owned this vehicle I have had transmission problems. Once it went from 70 to 20 on the highway. . It kicks or jerks at any speed. . . Especially going slow. . The shifting is horrible!!! the feeling of it losing power again like it did could cause serious damage to the transmission and unselfish and passengers. . I don't trust it on the highway!!! I keep a monitor connected to my truck at all times. . The dates coincide with the paperwork!! ongoing tranny issues all the time!! I paid way to much for this lemon!! engine vibrates around 80. . And if you don't use your blinker. . They truck fights you to change lanes. . It pulls you back!!.

Truck shifts really hard and is unpredictable. I almost drove through my garage door the other day shifting to drive from reverse. Truck will lunge forward or delay in shifting. There have been a few times I've had to slam on the brakes before I backed into something. I have brought it in 3-4 times for the issue and GMC won't remedy the problem.

Looses brake assistance in parking lot and sometimes on the highway,check engine light comes on with various codes the most common is misfire on startup it happen in different occasions.

8 speed transmission bucks, hesitates, lurches forward, clunks, while startung acceleration or coming to a stop. I try to keep a big gap between my truck and cars in front of me at stop signs because it randomly lurches forward and I almost have bumped cars in front of me. I have had the truck into the dealer so manu times to fix the vibration issues as well, they said 3 tires that came in the brand new truck were defective so I had to replace them all and the shake is still there, the balanced, rebalanced, road force balance and nothing works. Last time at the dealer said it is probably the tires, he said dont rotate them again and when they wear out he will put me in a �better� tire. I am past my warranty so the dealer says any costs are my responsibilitt, if the NHTSA could please step in to assist us to make gm fic theae vehicles which are a safety hazard.

This issue started a few months after I purchased the truck took it to two dealers they say its normal. Called GMC & they have no recall. When driving the truck & have to slow down in traffic the automatic transmission down shifts & has a very noticable jerk. Will actually jerk the hole truck. People who have rode with me tell me I have a transmission problem. What can I do.
