ENGINE
Driving my vehicle in the mountains pulling a 16000 lb 5th wheel trailer, the engine goes into Reduced Engine Power due to a Turbo Vane Position sensor / Turbo Over Boost or Under Boost fault. This has happened 4 times in the last 3 months and has nearly caused an accident following each occurrence. The vehicle is a 2016 GMC Sierra 3500HD with the 6.6L LML Duramax Diesel engine with 75000 miles. I believe the Reduced Engine Power protection is far to abrupt in the loss of Engine Power to safely move the vehicle out of the flow of traffic. During each occurrence I was in the left lane of a 2 lane expressway attempting to pass a much slower vehicle going up a 5-8% grade and was unable to complete my pass due to the loss in propulsion which nearly caused an accident.

ENGINE
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.

My transmission jerks randomly. It's done it since it's been brand new. When it does it, it is usually when it deaccellerates. I don't know if it's dangerous but I was hoping they had a fix for it by now.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
January 17, 2025 On [XXX] at approximately [XXX} 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.

ELECTRICAL SYSTEM, POWER TRAIN, STRUCTURE:BODY
Paint bubbling on roof. When turning on key, the radio makes a loud buzzing sound. On 11/16/2024, when leaving a traffic light, the truck began surging and shuddering. Tachometer was revving up and down like the transmission was slipping with loss of power while trying to take off and accelerate. While attempting to return home, loud booming noise was coming in from under floorboard. I was unsure if I would make it home before the transmission totally failed. People were passing around me because I was unable to acceleration fast enough because of the shuddering and loss of power. No previous signs of any powertrain issues or failures before. It happened for the 1st time today, and my truck is no longer safe to drive. GM has known about this transmission issue for years on several different models and has failed to broadly rectify the mechanical problem on all affected vehicles. Instead, GM has allowed the vehicle owners to continue to drive a vehicle with a known problem while it waited for a failure. This put me and my family at risk because I am driving around in a vehicle with a known transmission problem not knowing when it would fail or where I could be located when it failed. GM needs to pay for all repairs on all vehicles with this transmission failure because GM has known about this problem for years before someone gets hurt or killed. GM knew about the shuddering problem from the beginning, and they fixed the problem by tuning the transmission which then caused the total transmission failures over time which vehicles owners are not dealing with. Metal shavings are being located in the pan when inspected. GM should be held responsible for the cost of these transmission repairs. I would have never purchased the GMC Sierra 1500 if I have known GM was installing defective transmissions in new vehicles. That is shady, reckless, and unsafe. GM, pay to fix these problems.

ELECTRICAL SYSTEM, STEERING
While driving and making a turn at slower speeds, such as parking lots or intersections, the entire dash cluster including the radio screen will go black. The steering will completely lock up and jerk back to the opposite direction. At the same time the Park assist, stability control keeps flashing on and off. Sometimes the truck will shut off and then tell you to roll down the driver window and roll it back up. It is random and you never know when it is going to do it. The only fix I have found is to stop in the middle of the road and restart the truck. You can not drive off the road to do this because you cannot control the steering. I almost drove into oncoming traffic when it did this during a turn at an intersection. I have taken it to the dealership and they say then cannot duplicate it therefore don't know what the fix is. I have read multiple complaints on this on line. I have video but it is too big to send in this email.

FUEL/PROPULSION SYSTEM
i began getting a service engine light that went on and off a few times randomly. the vehicle would not switch down to 4cylinder as designed. there was an odd shudder as the vehicle slowed at 10mph increments which would randomly happen or not happen dependent upon the moment. i was outside of warranty so i went to a shop which has been very good in the past as opposed to risking dealership costs on top of the fact the dealership had no availability for quite some time. ultimately, i ended up replacing all fuel injectors and related equipment at my own expense. just happened to be online looking around after the announcement of gm reimbursing for similar issues on larger sierra engine and ran across a bulletin that only went to certain states in order to replace these injectors as they failed or reimburse for costs up to 10 years or 150000 miles from the time they were put into service. just curious as to why this happened in some states and not others when there was obviously and issue. i know this is probably not the forum, but a complaint is a complaint.
