2017 GMC Yukon owner complaints

This has been going on for a while now, but it’s getting worse overtime. If I push on my brakes more than twice the brake pedal locks up and I have to push extremely hard to get my vehicle stopped.. luckily I have never been going fast and had to worry about this. This is normally when I am pulling into a parking spot or I am backing up that I have to tap on my brakes a few times. A couple of times I have bumped the pole in front of my parking spot due to not having brakes. I just put in a general date as to when they started to get worse.

Driver side rear tail/brake light goes out when open and close rear hatch. Passenger side rear has same issue which was recalled and repaired. Tap the rear quarter panel or hit a bump tail light will turn off or on.

At parking lot speeds, there have been many incedents of brake failure, when pressing pedal to stop pedal pulsates and becomes very hard to stop the yukon. there seems to be a vacume or booster issue. Yukon will be fine for days then reaccure when slowing at stop sign or waitng at red light and moving foward in slow traffic to sign or llight and then in happens again. scary and unreliable when using brakes at low speed intersections or continous stop and go's

Tl* the contact owns a 2017 GMC yukon. The contact received three different letters from the manufacturer. The letter sent in april of 2019 stated that they were extending the warranty coverage. The letter sent in september of 2019 mentioned NHTSA campaign number: 19v645000 (service brakes, hydraulic). The third letter sent in november of 2019 indicated that the issue was not a recall and they were extending the warranty again.

Driving down the highway and brake pedal became hard to push down almost causing us to wreck. Keep seeing there was a recall for the brake vacuum pump and also brake assist warning came on. Also when driving low speed like in parking lot it takes a while for vehicle to come to a complete stop

Transmission shutter causes the car to vibrate which could lead to transmission failure.

Beginning around 56,000 miles the transmission started lurching and stuttering at slow speeds. It is worse when cold but never quite goes away. Dealership kept it for 3 days and felt it but said all was within normal range. Beginning around 65,000 it started stuttering when trying to accelerate while in motion, such as on the highway when trying to pass. This is not only annoying but dangerous when you can't get the power you need when needed because the transmission can't decide when to shift.

The contact owns a 2017 GMC Yukon. The contact stated that after starting the vehicle, the vehicle was vibrating abnormally. The front of the vehicle was shaking. The contact stated that while at a stoplight with the brake pedal depressed, the vehicle stalled but independently restarted. The engine warning light flashed on and off. The vehicle was taken to the local dealer, where it was diagnosed with transmission and engine failure. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and confirmed there were no recalls on the VIN related to the failure. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 50,000.

The transmission or torque converter are shuddering how do we fix, how do I protect family, will the transmission fall out on highway can I keep driving and be safety with family?

Vehicle Malfunction Incident Report On [11/2724], while stopped at a traffic light, the vehicle experienced a sudden and significant loss of power and gear shifting capabilities. The engine accelerated, but the vehicle struggled to move and shift gears, making it difficult to cross the intersection. After a short distance, the vehicle accelerated again, but there was no forward movement. The vehicle was subsequently parked in a nearby neighborhood, where it became completely immobile. Attempts to engage reverse or drive were unsuccessful. The vehicle emitted a loud noise, and a check of the transmission fluid and other fluids revealed no issues. After turning the engine off and restarting, the vehicle was able to engage drive, but it was limited to second gear. The vehicle then lost mome

the lifter is stuck an making a clicking noise an where on the high an truck cut off let it set for a minute then it crank by up an drove to a shop an they said it was a lifter stuck sounded like number 2 lifter this needs to be covered by gmc as a recall.

I started noticing issues with my transmission around 55,000 miles on it. It first started with no noticing that it wouldn’t gear down when it needed to, and then when it finally did gear down, it would really jerk the vehicle. I started calling GMC then and questioning and putting in a claim. Just went back-and-forth four months. Now it was getting worse to where I could feel the transmission slipping it wouldn’t kick into upper gear or lower gear. Again, I was still calling GMC and reporting these issues. I was told to take it and have a transmission oil change, which I did costing me $300. I still noticed this problem and I continue to call. I kept being told that they would have somebody call me back which nobody ever called me back to find out specifics. I took it to a GMC gar

Sitting at stop light engine began running rough and smoke coming out. CEL came on and began flashing, pulled over and had it towed. Diagnosis was PO300 misfire, dead miss on cylcinder 4, cylinder plug 4 is fuel fouled, cois is fine has good spark- caused by failed lifters. Needs engine replacement. Vehicle always serviced, garage kept and in mint condition with 89K miles.

The contact owns a 2017 GMC Yukon. The contact stated that the lifters were previously replaced in 2021 at the manufacturer's expense. Additionally, the contact stated that while driving at various speeds, the engine was running rough. The vehicle was taken to an unknown auto part store, where it was diagnosed with an engine cylinder malfunction. The vehicle was taken to an independent mechanic, where it was determined that the engine had experienced lifter failure or a more severe failure. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle needed to be diagnosed by the dealer, and that the manufacturer might help in covering the cost of the repair. The contact related the failure to NHTSA Action Number: EA25007 (Engine, Eng

My tail light is faulty. It is working some, shorts out, stops working, I hit a bump, it starts working again. Almost caused a crash, the lady followed me to the store to tell me it was out. Took it to the mechanic and it was working again without any repair. Does this everyday.

Pulled over by police for malfunctioning lhr brake light. Entire rear lamp assembly must be replaced since it is an integrated circuit board with LED lamps. $700 plus installation. Several victims on-line discussion forums.

My 2017 GMC yukon’s transmission is defective. The SUV will jerk and jolt when shifting gears. It is extremely unsafe to be driving when you need to release the gas pedal and press down again in order to shift properly. This causes an even more sudden jolting. This is extremely unsafe as a family vehicle especially when you have a newborn. I ask a recall be submitted since I see several reports of a similar issue with the 2017 GMC yukon.

Front magnetic shocks quickly failed, part no. Sk3354. Part has been on backorder for over a month, which means it is failing on many vehicles. Part is known by repair shops to be defective, but they say the replacement part lasts longer. Gm should pay something toward replacing this defective part, which is on many of their vehicles. Failure of this part causes vehicle to bounce excessively which makes the vehicle more difficult to control.
