2016 GMC SIERRA 1500 Complaints

i began getting a service engine light that went on and off a few times randomly. the vehicle would not switch down to 4cylinder as designed. there was an odd shudder as the vehicle slowed at 10mph increments which would randomly happen or not happen dependent upon the moment. i was outside of warranty so i went to a shop which has been very good in the past as opposed to risking dealership costs on top of the fact the dealership had no availability for quite some time. ultimately, i ended up replacing all fuel injectors and related equipment at my own expense. just happened to be online looking around after the announcement of gm reimbursing for similar issues on larger sierra engine and ran across a bulletin that only went to certain states in order to replace these injectors as they failed or reimburse for costs up to 10 years or 150000 miles from the time they were put into service. just curious as to why this happened in some states and not others when there was obviously and issue. i know this is probably not the forum, but a complaint is a complaint.

The 2016 GMC have an open recall for the Transmission Temp Sensor. It is throwing the code P0711 and P0700. For some unknown reason, my VIN is not qualifying for the recall.

Transmission began to shift hard at 55 miles per hour on Highway. Then when I got to a parking lot it began shifting hard and also in reverse.

I towed a trailer last month and noticed some hard breaking issues in slow moving traffic. Las night as I was parking my vehicle under the car port, I had to press on the brakes to straighten my vehicle and as I was moving forwards slowly, my brakes failed, the pedal was stiff and I almost hit my other vehicle and the garage door.

The contact owns a 2016 GMC Sierra 1500. The contact stated while driving at an undisclosed speed, the vehicle lost motive power. No warning light was illuminated. The contact opened the hood and heard a clicking sound. The vehicle was able to be restarted. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 136,000.

Driving at low speed such at in drive thru or parking lot if you press brake couple repetitive times pedal gets hard and you have to press really hard to stop it’s like vacumn assist losses vacumn in braking assist been happening last couple years but I’ve learned to adjust my braking at low speed to adapt

The vehicle has been in the dealership from where it was bought numerous of times for the same problem. Transmission shifts very hard from one to two and Has lots of slippage. Dealer recommended a transmission flush and it did not fix the problem. They would keep telling me that the transmission is normal for slipping and slamming hard while changing gears. I’ve been to multiple shops and nobody seems to know how to give me a correct answer or guide me on how to fix my problem.

Stopping at a stop sign with several cars in front of me my vehicle wouldn’t stop, luckily the car in front of me moved. I immediately called the dealership to have my vehicle repaired. They confirmed my brakes had a problem including the vacuum pump having an internal failure. They replaced vacuum pump and required belts then charged me $800.00 for this service.

Drivers side seat belt cable broke off where it connects to left side of drivers seat. It looks like a clean break I can send pictures

I have a 2016 GMC 1500 Sierra Denali and experiencing a very scary problem that has suddenly developed with this vehicle. As I am parking or in a slow turn, the vehicle completely looses all power [engine, electronics, brakes, etc..] and the steering wheel jerks out of my hands and then a second or 2 later it comes back on and then repeated 2 more times as I was attempting to park. I had this happen while turning into a parking spot at the store. Then the next day it did it a again as I was turning into a different parking lot. I loose complete control of the vehicle. I have been lucky not to hit another vehicle, more specifically a person. I decided to park the vehicle at home and not drive it until I get GMC service to diagnose. I have an appointment at a dealership to diagnose the problem on 08-15-204 at "Chevrolet Buck GMC of Puyallup Inc.". I did some research on the internet and found a site where others have experienced the same problem. I looked for recalls yet none are concerning my vehicle, however I did find a recall# N202325410 that fits the entire issue for some earlier vehicles. Same exact problem. Something to do with the steering column electrical harness. Please advise what recourse I have?
