general problems of the 2017 GMC Yukon - part 1

The contact owns a 2017 GMC Yukon xl. The contact stated that the check engine warning light was illuminated. The contact stated that while idling, the vehicle started shuddering violently. The contact stated that while driving to the residence at an undisclosed speed, the vehicle stalled and failed to restart. The vehicle was pushed into a church parking lot. The contact's father used a scanner to scan the vehicle, and a dtc for engine misfire was retrieved. The contact's father replaced the spark plugs, but the failure persisted. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine was blown. The vehicle was then towed to another independent mechanic, where the engine was replaced. Additionally, the contact stated that upon depressing the brake pedal, the brake pedal was stiff and required to be pumped several times for the vehicle to respond as intended. The contact stated that the failure occurred while starting the vehicle and while driving at various speeds. There was no warning light illuminated. The contact stated that the brakes had been replaced annually, but the failure persisted. The contact stated that the brake pedal shuddered upon starting the vehicle. The contact received a notification for abs from the onstar mobile app. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 148,246.

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.

At low idle speeds like in a parking lot we almost hit another car because the brakes were very hard to press. No power brakes. Felt as I was having to stand on the brake pedal with both feet to stop my vehicle from hitting another car at a grocery store parking lot going 5 mph! a light flashes on and says”service brake assist “ light goes away and drives normal and brakes normal except when you get to a stop sign, or traffic light. This happens a few times and I’m not driving the car because of it because I might hit someone.

Yukon break tail lamp problems. Brake lights work intermittently. Very dangerous! the break lights will work intermittently and then work. This was an issue with the 2016 models and gm issues a recall. There is no recall for 2017 which I don't understand because nothing has changed with the manufacturing process. I researched and there is a class action but in California only.

I am filing a complaint regarding a serious safety issue with my 2017 GMC Yukon xl related to the brake vacuum pump. According to recall information (NHTSA recall n192268490), certain 2015-2017 GMC Yukon and Yukon xl vehicles are equipped with a defective vacuum pump that may decrease in output over time. This defect reduces power brake assist, resulting in increased braking effort, a hard brake pedal, and extended stopping distances. These conditions significantly increase the risk of a crash. I have experienced symptoms consistent with this issue, including vibrating brake pedal with no slippage, a hard pedal, ticking noises from the engine, a 'service brake assist' warning message, and difficulty braking. This issues usually occur under 10 mph. These problems compromise the vehicle’s braking performance and pose a direct threat to the safety of myself, my passengers, and other road users.

Brake pedal gets hard and will not allow vehicle to stop. Intermittent issue, but caused vehicle to hit gate. Same situation occurred later that same week and vehicle almost rolled through major highway crossing.

The pump in the power-assist brakes puts out less vacuum power than needed, increasing stopping distance and the risk of a crash. My car rolls and doesn't stop. I have new brakes so this is unacceptable!!.

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.

I have a 2017 Yukon. There is a recall on this model already for a vacuum pump that decreases the power brake assist. My vehicle is having this exact issue. The back tire sounds like the compressor is always running and when braking it grinds at the pedal like a vibration and doesn’t want to stop immediately. I need my vehicle added to the recall list so I can get it repaired.

Transmission failed at 100,000 miles stalling vehicle brakes pushing back on me.

1. )rear brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2. )the suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3. ) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4. ) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

Stabilitrak warning light comes on intermittently. Cruise or anti-lock brakes do not work when this condition is present.

When backing down a boat ramp for a day on the lake I experienced extremely high rake pedel effort and abs engaging with no wheel slip for skid. In order to keep the vehicle from going into the lake I had to apply the parking brake. No warning lamps illuminated. The dealer states it is a faulty vacuum pump.

Passenger brake light assembly issues.

Tail brake light failure the tail brake lights have gone out on a vehicle that isn't 10 years old yet. Tail lights should not go out this quickly and the dealership will kindly replace them at $1300 per tail light. This is absolutely absurd! it is available for inspection. This definitely puts myself and others at risk! yes, this problem has been confirmed and inspected by a GMC dealer. Advised this is a very common problem with this vehicle. There are no warning lamps or messages to alert when the brake lights have gone out. Instrument cluster failure the instrument cluster is also faulty in this truck. This is the 2nd time within a year that I have had issues with this. Safety concern is that you will not know if the vehicle is running hot because the gauges stop working. Also runs the battery down as the fan continues to run for about 10 minutes after the vehicle is turned off. Yes, the problem has been confirmed and inspected by a dealer. Advised that this is a very common problem with this vehicle. No, there are no warning lamps or messages to alert you of the problem. You just notice a different noise while driving, the gauges stop working and then when you turn it off, the fan continues to run.

The contact owns 2017 GMC Yukon. The contact stated while driving from a complete stop, the vehicle hesitated to respond while shifting from first to second gear. Additionally, the contact stated that while driving at various speeds and depressing the brake pedal, the brake pedal would hesitate to respond, causing 40-50 feet stopping distance delay.

Service trailer brake system.

Brake assist went out. I have to use 2 feet to even stop.

Low speed breaking failure.

My brake lights work intermittently. If you tap the actual brake light they will flicker on and off. This puts others and my self at risk as the indicator for by braking system is not functioning properly. My vehicle has been to my local GMC dealer with a replacement cost of $950. 00. I also received a written warning from my local police department. There are no warning notices.

-back brake light system failure. -safety of a rearend accident compromised when tail light does not work properly. -yes, a repair shop confirmed the $975 unit needs to be replaced and is on back order for one month putting our safety at risk. -no warning has appeared. A person behind me reported it to me.

Brake peddle get hard while reversing at low speeds.

Brake light not working.

I purchased a 2017 GMC Yukon denali brand new off the showroom floor. I have maintained the services thru GMC dealership. I had to replace the struts and rear and front shocks due to hydraulic system leaking and locking up my brakes and causing extra pressure on my braking system to stop my vehicle. This cost me over $5000 to replace out of my pocket and I saw there was a previous recall in 2019 for similar problem but I was told my issues were not covered under the recall. I have also had to replace both taillights within 2years of purchasing my brand new vehicle and now they are out again. This will be my second time having to replace the led tail lights that cost over $375 light which were stated as never go out of lifetime guarantee. You cannot just replace the bulb you have to replace the whole tail light which takes weeks to come in and then additional labor costs. The previous.

The rear break lights malfunctioned and will quite working periodically there has been no inspection from a dealership at this moment and driving at night time puts me and my family at risk due to the fact that I could be rear ended and cause a major accident and my vehicle has no warning light or service light for this problem.

Water in 3rd brake light.

The brake lights fail. First the left light failed, and two days later the right light failed. After researching, this is a common problem with gm and these models. The fix is not just a bulb- the whole rear light assemblies (each side) needs replacing with gm price quotes of $900 a side. We were over 1000 miles away from home.

The contact owns a 2017 GMC Yukon denali. The contact stated that while driving on several occasions at slow speeds, the brake pedal was depressed but was stiff. The contact stated that the vehicle failed to slow down as intended. The vehicle was coasted until coming to a complete stop after each failure. The vehicle was taken to a dealer however, the failure was not duplicated. The contact believed that the failure was related to NHTSA campaign number: 19v645000 (service brakes, hydraulic). The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 43,000.

The brakes stop working. Brake assist comes on. When I press the brakes you can feel the pump is not working at all. This is happening at slow speeds mostly in parking lots but in fear of it happening when going faster. This needs to be fixed ASAP- dangerous to drive my children around in a car where the brakes just stop working.

Irregularities when brake is pushed at low speeds. Can feel various issues such as vibrating brake pedal, stuttering noise, loss in pressure of brakes and needing excessive pressure on brakes to stop vehicle. This has happened 2-3 times now, once in a parking lot, in a drive thru and when pulling out/in the garage.

While pulling into a parking space, the brakes shuttered and they wouldn't hardly work. Almost couldn't get the vehicle stopped. A warning on my dash said "service brake assist. " there was a recall issued in canada but non here for my vehicle so far. This is a dangerous safety hazard that needs to be fixed. GMC needs to establish a recall as soon as possible.

Tl- the contact owns 2017 GMC Yukon. The contact stated that when she had attempted to park her vehicle at a grocery store, the contact had to depress the brake pedal all the way to the floor board in order to stop the vehicle. The contact stated that the same failure had occurred twice after the original failure. She also stated that on one occasion the service brake assist warning message appeared on her instrument panel. Lafontaine Buick GMC of ann arbor(500 auto mall dr, ann arbor, mi 48103) was notified of the failure and the contact was informed that there were no recalls on her vehicle. The contact then took the vehicle to an independent mechanic who diagnosed the vehicle with a faulty brake assist that needed to be replaced. The mechanic then informed ## the contact about NHTSA campaign number: 19v645000(service brakes, hydraulic) which he linked to her failure. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 58,000. Jo.

I took my car to GMC because I live on a hill and when I park my car then put it into drive or reverse the brakes don't function properly. The brakes slide and skip and the vehicle has a very hard time stopping. It happens while putting the car into park on any hill, then putting it back into gear. It also happen when driving a slow speed on flat ground. GMC found the problem and stated it's under a special coverage warranty #n182202780-01. I've almost had it towed multiple times because I was afraid to continue driving, I'd have to go extremely slow down hills in fear the brakes wouldn't be able to hold me back if I gained speed. GMC doesn't know when the part will be in and states they won't provide a rental car. I am pregnant, so if I get in a crash going 5mph, it doesn't matter, I'll still have to get checked by a doctor. I'm an essential worker and still needing to have a daily vehicle. I don't understand how there is a found/known brake problem and they are telling me it's safe to drive when there was been over 100 accidents. They need to provide a rental car and fix it.

The latest issue began when driving on the highway, I noticed that the brake pedal would bounce when trying to slow down at highway speeds. I didn't think much of it. Exactly 2 days later, while approaching traffic at a red light at relatively low speeds, the vehicle would not stop. I tried to push the pedal, the pedal would go all the way down like it had no pressure. Luckily there was not oncoming traffic and I was able to swerve onto the left lane and finally into a parking lot where I was able to park using the emergency brake. My vehicle had recently been serviced for the vacuum pump recall since my brakes would become hard to push but only when moving at very low speeds like in heavy traffic or in a drive through service. I am concerned about the issue surfacing for a third time when I have my family in the vehicle.
