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.

- Ray City, GA, USA

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.

- Omaha, NE, USA

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.

Steering wheel jolts aggressively from the drivers hands. All electronics shutdown, engine shuts down, stabilitrak error & trailer brake on display. These conditions occur at any speed, going straight or turning. 25mph in city, driving 45 mph country roads or when stationary. Very dangerous!

- Medina, OH, USA

While driving the vehicle home from work, the vehicle shut down in the middle of traffic on a street while stopped at a traffic light and would not move after attempting to put the truck in "drive". I had to call for an emergency roadside service (tow truck) which towed the vehicle to a GMC dealership service dept. I was told by the service technician that the transmission torque converter has disintegrated and it would cost over $5000 to repair. This vehicle did not provide any warnings (no warning signal displayed on the instrument panel) that the transmission needed servicing. I have owned this vehicle for 3 years. This vehicle needs reviewing for a recall.
