2016 GMC Sierra 1500 complaints

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?

On a recent road trip my family and I experienced an issue with the Brake Assist on my 2016 GMC Sierra. When I returned back from our vacation I took the vehicle to a 3rd party mechanic that I trusted to perform diagnostics. He advised that I would need a new vacuum pump and stretch belt to correct the issue. Upon receiving this information I advised him to move forward with the repair. What I didn't know was that Special Coverage N182202780 covers this exact repair from GM at no cost to the customer. I followed up with GM to see if I could recoup any of the cost and I was told no because I didn't get the work done at a GM dealership. I find this to be extremely frustrating as I did not know there was a special notice that would have covered this defect, and if I had I would of taken the vehicle to a GMC dealership. I feel that GM should reimburse me for the defect that was known even if I had the vehicle serviced at my chosen mechanic. Any help would be greatly appreciated

My truck only has 40,000 miles on it and has the 8 speed 8L90 transmission. The truck bucks hard and has majorly delayed acceleration, especially on the initial startup of the vehicle. At this point the torque converter is going bad as well as the transmission fluid temperature sensor as per my mechanic when hooked up to the computer. It is now causing a fluttering of the RPMs, especially when the vehicle heats up after running for several minutes. It is severely impacting my fuel economy as well as my general safety when operation my truck. This is a known problem with this type of transmission but so far there has been no recall issued, only a class action lawsuit that I am having a hard time joining. It is going to cost me over $8000 for a new transmission and I don't really know where to turn at this point or what to do! Please make GM issue a recall for this known transmission problem that they put in millions of vehicles, all having similar problems as my own! Thank you!

Radiator leak. Low coolant, had to keep adding coolant. Only 76000 miles on truck. No warning other than the coolant temp was going up and down as I accelerated.

While driving I heard “sizzle” sound coming from the rear tailgate sliding window. I had my rear defroster on which I immediately turned off and the sound stopped. I got home 2 minutes later, parked the truck then an hour later when I was about to go back out to pickup my son I noticed the drivers side glass panel had shattered. I’m now aware of this issue under Customer Satisfaction Program [XXX] “Rear Window Defroster Thermal Event” and apparently this was a GM recall in Canada but not the US. I will take it to the dealership tomorrow and know they are going to say it’s my problem but that’s such [XXX]. Hoping they can cover this cost. I’m listing this here as a form of documentation…unsure if this institution can help. Thank you [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission shakes constantly not just when shifting. Repair shop says this is not repairable and is a common issue in trucks like mine. 2016 GMC Sierra. Vibrations are significant enough to cause a safety issue. Getting worse with time.

Braking system is malfunctioning while driving at slower speeds. It has malfunctioned while backing up and almost hit another vehicle. It also malfunctioned while coming to a stop light. Brake system is not working as it should and is feeling spongy upon braking. It feels like the brake pedal is all the way to the floor before it will eventually stop the truck. In researching this problem, there was a recall on the secondary brake system back in Feb of 2020. I bought the truck in June of 2020. I never got any information that there was a recall from the dealership I bought it from. I am unable to drive my truck due to this problem. I have not taken the truck to a GMC dealer as of yet but planning to.

Brakes go out at low speeds, especially in reverse. Makes it really hard to stop vehicle. It happens at least once every couple days and seems to be getting progressively worse.

Lost power steering at low speed, radio, ac and power to screen shuts off. Once the wheel is turned to the middle the power comes back on. Ive fixed this issue already last year and now again its happened a year later, they say now at 65,000 it is a rack and pinion when last year they said it was the battery.

The transmission overheated due to a poorly manufactured torque converter which caused my truck to come to a sudden stop on the interstate nearly being struck by several semi tractor trailers leaving my family and I in a dangerous situation. Upon research the torque converter and the thermal bypass valve fail causing the transmission to overheat with no warning whatsoever. It massively blew smoke out of the tailpipe blocking all lanes of traffic, completely unable to see that I'm broke down and nearly caused several accidents. Police was not notified since no accident occurred. The transmission preformed as its supposed to. No hard shifts or slipping between gears. This needs to be addressed by the NHTSA and GM as it's a huge safety issue. With no warning light indicating the transmission is reaching critical heat levels and shutting down poses a risk in the event you're towing a trailer/camper (As I was). Or even worse happening to those who live where they drive up and down steep mountain grades.

The electrical system keeps throwing a code for short to ground as well as low voltage codes. The voltage gauge on the dash shows either over charging or under charging. The in dash radio and screen shut off and turns back on by itself while driving down the road. Occasionally while backing up or pulling forward the truck completely stalls. The transmission was subject to the shudder issue, we took it to King Cadillac in Lake City, SC for the transmission flush. After the flush we have not felt the shudder, but instead Occasionally when pulling off from a dead stop, or while crossing the very busy highway my house is on the truck looses momentum almost as if the transmission is failing to engage at all, and all of the sudden about 15 seconds later it engages and accelerates at a rapid rate. The steering is extremely loose in the tires, however the steering wheel engages after about 3/4 of an inch. I have taken it to said King Cadillac multiple times and they maintain that the steering is 100%. Although I can not let go of the steering wheel and continue straight for any length of time. I am constantly having to adjust the steering to match the pull of the vehicle to avoid changing lanes or running of the road. After 60mph the tire shake is horrible, after 70mph it is hard to keep the truck in its lane.

Transmission problems. Had to replace at 95,000 miles. Seeing problems online with same GM pickups with less miles and transmissions going out. General Motors has a problem and not addressing it.

While parking in San Francisco after driving for about 100 miles, the brakes felt they had lost all power, the pedal was pressed down to the floor and caused the braking distance to increase drastically. There was a fence post to the left of my truck. So I was going to go forward a little then back up and straighten out to pull forward and finish parking. Going slow 3-5MPH I pressed the brake and the truck kept going forward, I felt a shake from the brake pedal and then no pressure, straight to the floor, then the brake pedal didn’t return up. i kept pressing/pumping the brake pedal but still felt like there was no power at all. When you released the brake pedal the pedal would not return to the top like normal. So the truck would not stop, it felt like forever, but when the truck did stop it had just come to rest on the fence post left of me, causing a small dent on the, rear passenger, driver side door. This was really scary because I was parking on a ocean pier and I though I was going to go into the fence in front of me and then into the water. I know now that that was most likely not going to happen because of the low speed I was going at but non the less SUPER SCARY. So now I have a dent on my truck and I am also scared to drive the truck because the brakes might not work when I need them too.

Power brake booster failed, truck would not stop in a timely manner

The contact owns a 2016 GMC Sierra 1500. The contact stated while driving 65-70 MPH, there was a clicking sound coming from the vehicle.

My truck started having a strong fuel smell by drivers door. 7/11/23 I took to the GM dealer to address strong fuel smell. The dealer at Patriot GMC said they would have to drop the tank and do smoke test to locate leak. They reported no leaks found that it looked like possible fuel on top of tank from over filling and spill. I explained I didn't overfill tank or spill any gas. Picked up truck after being told no fault found. I had to pay $539.91 to drop gas tank for testing and to check fuel pump.7/17/23 [7/11-7-17] I explained no trouble with starting or stalling with fuel pump and I just had gas smell really strong. Engine light came on when I left shop so I called dealer and explained my truck was running fine and now engine light on. I brought it back to shop after a week of testing and put back in shop on 7/17/23 They took the code and it came back as EVAP system issue. Code P0449 They said my EVAP Vent Solenoid valve circuit was open. Circuit tested terminal 1 pin loose. Terminal in connector replaced. Vent valve tested. The mechanic stated now running as designed. Multi point inspection completed. Picked up vehicle and stopped at store because I could smell gas real strong inside my cab and under hood. I contacted dealer for third time about gas smell and this time I asked for shop manager to come to vehicle so I could make sure he could smell how strong the gas smell was and now it was coming from front hood area into ac vents and into cab and it was making me nauseo

Brakes will sometime seize up and not allow car to stop in sufficient time.

Factory welds in Condenser coil are faulty, causing refrigerant to leak and Air Condition system to no longer work causing health concerns for children, pets, and driver or an vehicle that cannot be driven in the summer months.

Electronics flash on and off then steering wheel jerks hard back and forth. Total loss of everything.

Torque Converter failed and destroyed the transmission at 79,600 miles

The transmission is almost banging into gear vibrating at high speeds the shifts can jerk the vehicle and cause an accident

The contact owns a 2016 GMC Sierra 1500. The contact stated that her husband had to frequently add oil to the engine.

Air conditioning condenser cracked not working

The contact owns a 2016 GMC Sierra 1500. The contact stated that while starting and driving the vehicle, the engine experienced rough idling with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with a cylinder misfire and that the spark plugs needed to be replaced. The contact declined the repair, and the vehicle was taken to an independent mechanic, where it was diagnosed with codes: P050D, P2099, P219B, and P0300 for the fuel injector. The contact related the failure to Special Coverage Adjustment N182198000 (Engine Fuel Injector); however, the VIN was not included.

Dash flashed Steering assist reduced while I was driving and then I lost all power steering nearly crashing the vehicle. Upon bringing vehicle to a stop I turned off vehicle exited and looked under hood for anything obvious. Upon restarting the vehicle warning was gone and power steering returned. I was advised by GM that a recall for this problem is available for previous year but not mine. I am afraid to drive vehicle, worried the problem will occur again.

When in park and I shift the transmission into Reverse, the force engaging the gear bangs and shakes the vehicle. The transmission is not regulating the power. The vehicle is available for inspection. I took the vehicle in to the dealer service and they were able to reproduce it. They claim that there is a bulletin from GM motors and this is considered normal. The bang is hard and shakes the vehicle, definitely not normal. It started after 50k miles and the truck has 62k miles now. No one else inspected the vehicle and no warnings are indicated by the vehicle.

Out of the blue I am getting constant trailer brake system alarms dinging at me. Even if I select dismiss the alarm keeps coming back. There seems to be no way of getting this to stop.

The contact owns a 2016 GMC Sierra 1500. The contact stated while driving 60 MPH, the instrument panel went blank with white smoke coming from the vehicle. While approaching a stop light, the brake pedal depressed to the floorboard; the contact used the parking brake to stop the vehicle. Once the vehicle came to a stop, the contact was unable to turn off the vehicle. The contact poured water over the engine as the heat melted a switch that connected from one battery to the other. The contact managed to restart the vehicle and resumed normal driving. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 200,000. The contact stated that the failure mileage was at or around 157,000. The cause of the failure was the second battery's positive cable became shorted out.

The torque converter jerks the truck and causes vibration. This does jerk the vehicle unsafely at times of stop lights. As I know this was a lawsuit at one point with GMC itself. It does nothing but get worse with pulling and jumping the truck going down the road.

For over a year now multiple times while I'm driving. My vehicle's power steering will jerk/shake very abruptly, dash lights, radio, a/c & heater flicker on & off, service stabilitrak, trailer brakes etc, will pop up. then once stopped and shut off the engine the battery will act like it is dead and I will have no power to the vehicle at all. I have read the recall report & over 1 million SUV/Pickup GM vehicles (Chevy/Cadillac) manufactured through October 2015 are affected with the same issues. My 2016 GMC Sierra 1500 manufacture date on the vehicle is October 2015. I was told my VIN # was not included with the recall therefore they can't do anything to help. Even though my vehicle is experiencing exactly the same problems as the vehicles that were recalled and fixed with no out of pocket expense I am basically screwed. I also have a video of my steering wheel jerking back & forth, dash lights flickering & the engine stalling. (All in the same video)

I was getting off the freeway making a slight left turn yield and from the no where the steering wheel by itself turned to the right side almost making me loose control of my truck, I was driving about 45 mph when the incident happened. Then a second time happened about two-three weeks later when I was making a left turn to stop by a gas station, I was making the turn driving about 5-10 mph. This is something very serious. If it happens when I’m in the freeway it could make me loose control of my truck and someone could get hurt.
