general problems of the 2016 GMC Sierra 1500

Noticed the bed of my truck was touching the cab when looking under truck the frame is total structural failure rusted all the way threw on the driver side and beyond.

January 17, 2025 on January 14, 2025 at approximately 9: 30 . P. M. I was returning from walmart. 3 doors from my home I heard and felt a loud pop thinking maybe it could be a hose or something because it was extremely cold 7 degrees but everything seemed fine. Today I decided to have my vehicle washed and waxed since it’s 40 degrees but on my way to the shop it sounded like a window or door was open. When I got there the young man immediately said that my rear window was broken I said it couldn’t be because I really leave my home but I looked closer and it was shattered, he said he had heard of that when it’s cold and using your defroster heating up the wire causes it to explode is probably what happened and there may be a recall on it and there is n192265660.

Welds on condenser are leaking freon. I had a shop evacuate a/c. I keep getting told my truck VIN does not have a recall for condenser even though I am seeing recall info for condenser.

Rear window exploded make it a full recall finally. Jeez.

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 nauseous and scared of fire issue. He said he would get it fixed. Received call yesterday stating that they found a small crack in fuel pump and my truck was ready for pick up. This is the same recall notice I have read about on major recall of GMC vehicles due to crack in fuel pump. My truck is a 2016-2017 but I don't see it on the recall list or have I been notified of the issue. #n192283991 safety issue pressure regulator cracks fuel pump. 19v837000.

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.

Air conditioning condenser cracked not working.

The a/c condenser has a crack and leaked out the refrigerant. Is the manufacturer covering this repair. It does seem to be very common. 2016 GMC sierra. I did put dye in to locate the leak.

The ac condenser failed and ac will no longer work. This puts my family at risk during the hot summer days and can no longer use it to transport them due to extreme temperatures while not constantly in motion. Problem was confirmed by mechanic when I brought the truck in regarding ac no longer working. This is a known issue and I am requesting gm to finally release an official recall.

Similar to the canadian recall that effected those models, the rear defrost on the power sliding window malfunctioned, produced a weird smell like fire and promptly exploded, shattering the window. Vehicle is being used normally with no aftermarket products.

While driving a hissing sound was heard from rear window, smoke appeared and rear window shattered. Dealer states that there was a short in the electrical system consistent with recall # n192220470 and that my vehicle does have rpo a48. My vehicle was not included in this recall due to geographical location of vehicle (pennsylvania). This is a known potential fire risk and glass shattered into the vehicle. It should be noted that the outside temp was 60 degrees and my husband did not turn on defroster or open the rear window. After the smoke clear and window shattered he noticed that the defroster light was on and he shut it off manually. Had there been rear seat passengers they would have had glass on them and subjected to smoke and possible fire. God forbid a child in a rear facing child safety seat was back there, they would have been at serious risk of harm. Gm has been notified and at this time is refusing to include this vehicle in their limited scope recall. I know of several others with similar stories (avail upon request), one lives in south carolina, proving that this recall should not be limited to northern tier states. The current recall must be expanded to all 50 states ASAP. Lives and property are at risk.

I used my remote start to start my 2016 GMC sierra to warm it up while cleaning the snow off my other windows. I smelled smoke and noticed my drivers side back window completely shatter before my eyes. Upon further investigation I see many ppl that have reported similar incidents occurring in GMC vehicles years 14-18 some even with shards shooting into their vehicles. This is completely ridiculous, and extremely unsafe and could seriously injure someone. The vehicle was stationary and started by remote start.

Smelled electrical burning and then seconds later the driver side of my rear window exploded into pieces with a loud bang.

A/c stopped working. Great on Friday, did not drive over weekend, hot on Monday.

When is riding it on the road it shake ,on the road is when it do it.

Here is what happened regarding the rear sliding-window shattering (and nearly a fire) in my 2016 sierra: on January 1st, 2020, I was driving straight at approximately 30 mph on a smooth, level city street (no potholes or road defects, etc. ) in 25-degree weather with my rear-window defroster on when I smelled something burning and looked in mirror and saw smoke and a few seconds later the driver's side glass-panel of my sliding rear-window shattered. There was no ice on window at the time and I had been driving approximately 7 minutes. I know that gm has acknowledged this problem and issued a recall #n192220470 on canadian vehicles, and that there is a major fire hazard. I spoke with anderson Chevrolet and grossinger GMC this morning (January 2nd) and was basically dismissed and told to call gm about it, they won't help me.

Rear window glass on driver side of sliding rear window exploded after using defrost in cold weather while driving on the interstate.

My truck was parked at a business. I started the truck after being inside for about 10 minutes and started to smell an electrical burn/shortening. I turned the truck off, told my wife to get out and I popped the hood. By the time she walked to the back and me to the front, the rear window behind the driver shattered, sending glass inside and outside the vehicle. After opening the doors for a few minutes, the smell was gone, since I work with electronics for work, is normal for the smell. I think it was defroster and/or the sliding rear window wiring. This happened on 12/03/2019. I had escalated this up general motors customer relations and after level 2 was told it was not their issue, even after I referenced the canadian recall for this very issue. The truck, per my service writer todd, has since been recalled but I cannot find anything anywhere. My truck is still at the dealer, woody Buick GMC, naperville, IL and has not been repaired. That's also why I can't send a photo.

The vehicle shakes at high speeds of 40 mph and higher.

Ac condenser failed at 40000 miles. Gm has extended warranties for their suvs related to this common and known issue, however has not included their trucks in the warranty extension. The faulty condenser is the same exact part for the trucks as the suvs and as such should be included as well.

I was driving down road and back drivers side window exploded. My granddaughters were sitting in their car seats and were showered with glass. The window literally blew up. I called dealer, he said he's never heard of such a problem. I found several complaints on my GMC forum page and wxyz 7 in detroit, mi. Has run stories on this problem.

Ac condendor. I am having to replace the ac condendor on a 2 year old truck at a cost of over $1000. Truck is just over dealer certified warranty by 6,000 miles with 54000 miles. After being told by dealer that this was a known issue and researching online, it appears that is a costly repair that is affect large numbers of owners. Gm has offered extended warranty on similar vehicle that have this engine and condendor setup but not included the sierra. Appears to be a known manufacturer defect that they are not covering.

We have violent shimmy/shaking issues with our truck and have since we got it brand new. We have taken it to the dealer 5 times and even had the dealer witness the shaking the last time while on a test drive. They replaced the torque converter, rebalanced the wheels, and rotated the tires and the problem continues to happen repeatedly. We do not feel safe driving this truck any longer as it happens at speeds above 40mph. The dealer says they can't fix it if they don't know what is wrong.

(1) the truck hesitates and the engine almost shuts off like it's not getting enough gas, it does this for about the first 45 mins. Of startup. (2) the battery has been replaced for the second time and even with a new battery it sounds like it's barely got enough power to start the engine.

Constant vibration and or shake at speeds between 60-70 mph. This issue is commonly referred to as the "chevy shake" this issue has been existing since first purchasing this vehicle. I addressed the concern with the dealership during multiple visits for service. As this was my first full size truck, I wasn't sure what to expect regarding how the vehicle would ride at highway speeds. I was told by the service department that the vehicle was in tolerance in regards to how it rode and the constant vibration. So I excepted this as being the norm and went ahead to add some modifications to my truck. Since the initial complaint the service department has since turned over most of their staff and added people willing to address and acknowledge that my vehicle indeed has this vibration/shake issue. Due to the modifications made they will not address or attempt to correct this issue. Had I pressed the issue in the beginning and not accepted what these so called professionals had told me to be acceptable maybe I wouldn't be in this predicament. My vehicle has also been in for numerous bucket seat issues from sagging and poor seat support. Everything described here is factual as I have all the service records and history with the same GMC dealership and service department in regards to these problems. Long story short, these issues have made long distance trips almost unbearable between the constant shaking and poor seat support.

I have a 2016 GMC Sierra 1500 5. 3l. I've brought the truck down to the dealer 4 times now because the ac doesn't blow cold air. The ac stopped working again this week with the truck only having 2,800 miles on it. I called GMC directly (not the dealer) because I don't want to bring the truck down to the dealer for the 5th time for the same issue. It's 85+ degrees now where I live and driving without ac is unbearable, especially when in traffic. Gm sent me an e-mail informing me the ac condenser is faulty by design and a 'redesign' has been created. The part is on "national back order" with no eta. They said it could be 4-6 weeks which means driving my truck without ac is very uncomfortable and not an option with children in the truck who can't withstand the heat. I'm reading on various forums that people have been waiting since March (4 months) for the new condenser to come in.

I purchased my 2016 GMC sierra sle double cab on 9/13/2016. My truck begins to vibrate/shake at 40 mph and gets progressively worse to 70 mph. The shake can be felt in the drivers seat and floor. The center console shakes and shudders making me feel nauseous and dizzy while driving at hwy speeds. I returned the truck to the dealer within the first 500 miles. The wheels and tires where forced balanced with no relief and then all four tires were replaced. The wheels and tires I purchased with the vehicle were a dealer add of gm 22" wheels and tires. The vibration was not as apparent after the new tires were put on but now that I have put an additional 1700 miles on the truck, the vibration and shake is back as originally reported. During a 3 hour road trip on 11/2/2016 I had to stop and let my passanger continue the trip because I was ill from the shaking and vibrations. My sales person initially told me that what I was experiencing was how 22" wheels feel. I had a 2012 silverado lt z71 and a 2014 silverado lt that had large wheels and I did not have. Any shaking or vibrations. I have made another appointment with another dealer to seek relief.

Since buying the truck new in 2016 it had a vibration , which got worse as you increased speed, at highway speed, 65-75 mph the vibration is so bad it was making me nauseous. I have taken it to the dealer several times, first balanced the tires and said everything was normal, truck still vibrating. Several more trips to the dealer with the same result.

A week after purchasing my new 2016 GMC sierra denali 1500 short bed I began noticing a strong vibration/shake that could be felt while in motion at highway speeds between 75-80mph. The flatter the road the stronger the vibration can be felt at these speeds. I have brought it in twice to the dealership I bought it from and once to another dealership yielding no fix to the problem. Actually, I have been told there is no problem and that is how the truck rides. I have also been told my expectations for a pickup truck "unrealistic. " when the front and passenger seats physically shake at the speeds mentioned I find it very hard to believe that there is no issue with the vehicle and that my expectation should be considered unrealistic. Driving the truck long distances on the highway is unpleasant at best creating at times feelings of nausea. I have zero confidence the issue will be addressed, but wanted to air my complaint for other potential buyers. This truck is supposed to be the top of the line and I absolutely regret buying it with this persistent problem present that nobody wants to address.

Vehicle has a vibration that gets worse as speed increases. Gm not being able to determine the origin of the problem has said it is not a safety issue. The very fact that they cannot find the origin makes it a potential safety issue. After much diagnostic work and parts replacement still no answer.
