2016 GMC SIERRA 1500 Engine Problems

The contact owns a 2016 GMC Sierra 1500. The contact stated that while her and her husband were driving on several occasions at various speeds, the brake was depressed; however, the braking distance was extended, and the vehicle took longer to slow down. The contact also stated that occasionally while driving at undisclosed speeds, her husband observed a loud sound coming from the engine compartment. The vehicle was taken to the dealer where it was diagnosed and determined that the engine and braking system needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

I have not experienced a failure as of yet. But the CP4 fule pump is prone to fail. With that failure the engine is destroyed as well. So why is there no recall to get the CP4 fuel pump replaced? GM has been sued correct? A settlement of $35 million due to the failure of the CP4 fuel pump. So why is there no recall to address the issue before it happens? I have contacted GM directly and got no assistance. They just told me to fill a complaint. My Vehicle is a 2016 GMC Denali 2500 with the Duramax motor. This issue needs to have a recall! Why should owners of these vehicles with the CP4 fuel pumps have to wait until it fails and cost thousands of dollars to get assistance or reimbursement. Would appreciate any help with this matter. Thank You.

Having the same issue as the recent recall on the 6.2L v8 engine failures. This has been an ongoing issue from well before the 2021 and up manufacturing dates according to many online complaints. My vehicle now needs a motor due to complete failure.This came out of nowhere with no warning very recently. It is not drivable and a new motor is not in my budget when I still owe money on the truck. GM needs to step up for the rest of these failures.

My truck uses excessive oil .i bought my truck on [XXX] and we decided to take it to pipestone camping for the weekend in August of 2023 . I still had roughly 3000miles before my next service . We left on a Saturday night to go home around 12:30 am . it was a 4 hr drive and about 3:00am my oil light came on . Before we left i checked the oil and it was full I stopped at the nearest gas station which was 10 miles and it took 2 and1/2 quarts to hit the full mark then went to Arkansas with the truck, just had it serviced prior and checked myself before we left and it was good . We drove there and back I checked at every gas fillup. The light never came on but when I checked the next day it was 2 1/2 quarts low this was this past January of 2025 it’s gotta be blowing past the rings or something with the pcv system ,but this is far from routine and could destroy the motor or at the least severely diminish the longevity of my truck and [XXX] knows of all safety concerns anywhere from engine seizing up all of a sudden driving down the interstate at speed and losing power to everything. Degrading the oil like that is not good for any internal parts . Now every time I start it the lifters tic and it only has 84263 miles .This is a very expensive truck . I take care of my vehicles to make them last and I can’t afford another pickup in this price range which was 38,000 in 23 . I know I can’t be the only one complaining about this issue . I’ve had it serviced by a outlet of the dealership I bought from it only been serviced 2 times that I know of since I bought and well before the service it’s been drastically low on oil with well over half the miles left before the next service . To me that’s insane . I have a ford fusion I’ve never added oil since I bought it and it has twice the millage . Gm needs to take responsibility for this and get these autos fixed before there is a fatality because of the faulty cheep parts they put in these trucks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

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?

My 2016 GMC Sierra 1500 (5.3L 8-speed). When on the highway or in the city when the truck is changing gears it has a shake almost like hitting small bumps on the side of the road. I have several friends and family members with the same model truck and have spent thousands of dollars to fix the problem by modifying the whole truck. Is there anyway a recall could be made since it has to be a huge issue with all models with the v4 mode? I brought it to a transmission shop due to GMC dealerships being booked for weeks..the receipt is attached! They said the fluid was burnt and changed it but need new torque converter!

The engine light has come on with issues for transmission and the engine is shuttering/skipping. The tech found lifter failure and truck needs a transmission. I have been in contact with GM about this issues and submitted the repair cost for review.

When placing the truck in Drive, there is a very hard 'clunk' between first and second gear. Additionally, when driving, the truck shakes/shudders, mostly on the highway, but sometimes in town when driving between 25 and 70 m.p.h. The first instance was in March, 2019 whereby the dealer indicated this was normal operation for this transmission. As it seemed to get worse, I took it back and was told the transmission fluid was the wrong type and I had to pay to get it evacuated and changed out, even though this was an error on GMs part.

I purchased the 2016 GMC Sierra new. From the very start I felt there were issues with the transmission. I took the truck in for the shaking, vibrations and clunking in the trans with 5058 miles. Over the next 36 months I had the truck in 7 times and 3 different dealerships to get the trans fixed. Only once did they really do anything where they changed the fluid. I lived with the issues after the warranty expired as GM would not do anything to fix it. Now at 66,000 miles the vibrations have gotten so severe I am afraid to drive the truck. At no point has the truck not had vibrations, only they have increased. And now I have had 2 check engine warnings both dealing with the trans.

-Engine gas consumption states 21 MPG Highway, 17 MPG combined and 15 MPG City. -When I started using vehicle during the first weeks and months the best MPG I could geta at the highway was 18.5 MPG with top-tier gas. -Ever since I bought the vehicle, the gas MPG have gone down around 0.5 MPG. The vehicle feels that it has to use more gas in order to perform the level of task everyday. -The motor oil pump at times moves down from the 40 mark to the 20 mark when idle at traffic light and it starts moving, it temporarily goes to the 60 mark. At other times when idle it stays in the 30 mark. -The transmission is an 8 speed automatic. It has issues shifting 1st and 2nd gear, and at times 3rd gear as well. When driving at slow speeds like in a traffic jam, mall parking, do a u turn or when you slow down at the traffic light and then turns green and you start accelerating again it feels harsh on gearing up and down. -This vehicle has the Active Fuel Management (AFM) system, it turns on even at slower speeds and you feel how the engine and transmission struggle to accelerate, go a gear up and push the vehicle with only 4 cylinders. Like in manual transmissions when you accelerate on a higher gear than the correct one, it takes forever to accelerate and properly change to 8 cylinder and establish the correct gear and ratio. -Even if all 8 cylinders on it it feels like if I am running on a smaller engine. -There was a fix done to the transmission for a valve, but the vehicle still runs the same as before. -There is a knocking noise starting to build in the engine. Best mileage I can get driving the same and gas is 13 MPG combined. -The recent safety recall for the breaks is actually making the breaking worse than before. -My vehicle is 2016 GMC Sierra All Terrain V8 5.3L 4WD Z82 with 36,500 miles on it and is doing all this and its getting worse little at a time.

Experienced error code of P0307 after vehicle backfired while on highway. Check engine light and stabilitrak lights immediately turned on and vehicle was shaking violently. Immediately took vehicle to an independent shop to have it looked at. After running diagnostics, pressure tests, and bore scope. It has been determined that piston in cylinder 7 is a complete loss and has a 0 pressure reading. From talking with shop owner he said he sees this issue quite often with GM vehicles due to DOD or AFM (active fuel management) that GM has on their engines. I'm at just shy of 67k miles, out of warranty, and needing to replace the engine.

Truck was purchased on 11:28:20 and had my first oil change in March. Started noticing a ticking sound coming from the motor but it was. Very faint. After a while it went away. After a few weeks later the noise started to get louder and started shaking. Took to the near mechanic and he diagnosed it with bad lifters on the passager side.. I took it to another mechanic where their replaceming all lifters for 4.8k. This truck is not too old and I shouldn’t be replacing any engine parts. It only has 100k miles and it’s a 2016.

-Engine gas consumption state 21 MPG Highway, 17 MPG Combined and 15 MPG City. When I started using this vehicle during the first weeks and months the best MPG I could get at the highway is 18.5 MPG with top tier gas such Shell & Chevron during the first 2 years and now Costco brand. Every since I bought it, the gas MPG have gone down around 0.5 MPG. The vehicle feels that it has to use more gas in order to perform. -The motor oil pump at times moves down from the 40 mark to the 20 when idle at traffic light and when it starts moving, it temporarily moves to the 60 mark. -The transmission is an 8 speed automatic. It has issues shifting to first gear, second gear and times 3rd gear. When driving at slow speeds like in traffic jams, mall parking lots or when you slow down at the traffic light and then turns green and you start accelerating again it feels harsh on gearing down and up, like someone rear ended your vehicle. -This truck has the Active Fuel Management (AFM) and it turns on even slower speeds and you feel how the engine and transmission struggle to really gear up and down. Like it never gears and tries to accelerate at a higher gear. Like in manual transmissions when you accelerate on a higher gear than at correct own it takes forever to reach the needed speed. -Even if all 8 pistons are on it feels as if I am running on a smaller engine like a V6 or V4. -The driver car seat feels that move a little like an 1/8 of an inch. -It just feels that something is wrong with motor and transmission.
