2016 GMC SIERRA 1500 Complaints

Paint is failing and delaminating from both rear doors around windows and also the truck bed.

The vehicle stopped dead in traffic and would not restart. No warning lights. This is a huge safety hazard. Had to be towed to a dealership. The dealership and other diesel shops said the issue is a known catastrophic CP4 fuel pump failure. The fuel pump shreds and metal shavings are found throughout the fuel system. Requires a full fuel system replacement...quotes have been obtained from GM dealership and local diesel mechanics, ranged from $15,000-$17,000. There is a known fix and could have been solved by replacing the fuel pump with an alternative one, without putting us in a dangerous situation. There is also a settled class action lawsuit directly associated to this fuel pump and issue, however the vehicle was purchased in GA and therefore not included. Based on the VIN the truck would be included if sold within a qualifying state. GM corporate and dealers know about this problem and the safety risk, but are not even suggesting the fuel pump conversation as a repair. They are putting customers in dangerous situations and leaving them with high bills.

My vehicle a 2016 GMC Sierra 1500 upon lower idle speeds loses vacuum pressure. As the vacuum level drops the brake assist decreases, increasing the braking effort, extending the distance required to stop the vehicle, which increases the risk of a crash. I have had a warning light come on advising to service the brake assist system. I took my truck to a local mechanic who confirmed the codes and learned that there had been a GM recall associated with this failure at one time, with GM recall # N192268490. There is also NHTSA recall bulletin 19V645000 regarding this matter as well. Upon contacting some local GM dealers in the area, I was informed that my VIN was not listed as one of the vehicles affected by this recall, so a recall notice was never sent regarding my vehicle. I was also told that I just fell outside their 10-year window regarding this matter and that they would not repair this safety issue under warranty. I called the GM customer service who could not explain why the VIN associated to my truck was not listed and they said I should contact NHTSA and start a claim for potential reimbursement in the future after repairs are made. I feel that this is an unnecessary step as I believe GM should honor their product and repair an obvious safety issue with the truck, especially since they knew this was an issue in thousands of their trucks where it was not my fault my vehicles VIN was not included as a potential recall issue, but I am following their suggestion

Catastrophic engine failure while traveling 40 mph. Dealership diagnosed as cylinder walls being scorched and rods blown through. No warning signs existed - just had a loud thud before the check engine light started flashing and grinding sound started coming from engine.

I noticed a "ticking" noise a few years ago, it wasn't that bad and while taking my truck to the dealer for an oil change I ask about it and the representative told me that in this models that was normal. Since it wasn't that bad and the truck didn't show any problems at that time, I just decide to let it be. This weekend I took my family out of state for a fun trip, and while going in the highway around 55-65 miles per hour, the truck suddenly lose power, it felt like it the truck "sits" the cars behind me had to dodge me and I lost control of the truck and had to steer to the right getting out of the highway and almost go into a ditch, thankfully nothing scaleted to a big and disastrous accident. The engine light started to flash. And suddenly stopped, I turn off the truck checked back for my family and after a few minutes, I started the truck again, the truck started right away and but I noticed the "ticking" got a little louder, talking to my neighbor about this he told me he had the same issue and hes motor went bad and they said it was a bad AFM system causing this, I started searching on line for it and see there been the same issues with the AFM with other drivers, and seen that the have the same issues Im confident that it is an AFM problem. Truck is been running and is my daily work car and I notice is loosing power, I contacted the dealer but haven't had any answer yet. I cant take it to a mechanic shop because they would charge me in between 2,500 to 5k to fixed, money that I dont have, while in the call with one shop he told me about this place to put a claim and notify about how dangerous this can be if in a highway.

The local dealer was contacted, who confirmed there were no open recalls. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was unknown.

1- transmission issue, it’ll occasionally slip from 1-2 gear and engine rpm’s will shoot up making it when you release the gas pedal it’ll kick into second gear it’ll also do minor kicks into other gears (8l90 transmission) 2- breaks issue, unsure of what the problem is but at very low speeds like parking or going in slow traffic the break pedal will get really hard making you have to press extra hard for it to break, releasing and pressing again doesn’t help either

since we have had this truck the transmission has not worked right to where no longer works plus we have paperwork from other dealship have said this truck should have never been sold to us by the other deal they told us this truck has a lot of issues and is not road safe we where told by that dealer they cant help us so we need help with this the truck don't even have 100,000 on it the truck also pulls to the light sometimes and sometimes to the right .....

Engine has developed a serious lifter / cam issue. dealer identified it as a result of Displacement on Demand design. Total engine replacement recommended by dealer but since the mileage on that vehicle is over 100,000 warranty, the repair is not covered. Known issue, should have been pointed out by dealer / manufacturer before warranty expiration. FYI _ I do all repair work at dealer. Vehicle looses power intermittently is is not drivable at any distance. Manufacturing / design issue known over different versions of this engine since 2010, I believe.
