2017 GMC Yukon XL complaints

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.

AC stopped blowing cold air. Took it to the dealer and they are saying based on where the leak is it needs a new compressor. There is a recall / special coverage for other GMC 2015-2017 for this exact issue.

The paint on the hood is peeling/flaking and is degraded. Right air shock is leaking causing the vehicle to continually pump up. I have the tow package, and with the air shock leaking, it does me no good. My air conditioner has not been cooling for a while. I started noticing it when it was hot in December, 2022. Would have thought it was a simple leak. The port valves have been changed. Air is still not blowing cold. My vehicle uses the R1234YF which is very expensive per can. After spending $72,000 on a vehicle, you would think that it would not be failing so soon. I understand 1) there is a class action lawsuit regarding the peeling/flaking of the paint; 2) that the ac condenser has a recall and also, the "leaky" air shock; however, my VIN is not included in any of these recalls. Upon the pleading and begging for recall information on brake lights and the brake system, those after sometime, were actually fixed by the dealer. I feel like I purchased a lemon. This was supposed to be my forever vehicle. To make matters worse, my vehicle display freezes when you are driving down the road, which includes while you have navigation on, I guess I will just get lost. I have had warnings about parking/collision alert just not working and will not let you push the button to turn it back on. I am not understanding why all of what is happening. I work everyday and have to take off work to take it to the dealership. I have never been so disappointed in a GM product, my vehicle is a piec

My driver side tail light is not working. The passenger side tail light flickers in and out.

Rear brake light has stopped working. GMC dealer quotes $990 to replace one tail light assembly. It appears to be a common problem caused by a weak conductor that breaks inside the assembly. Because of the high price quoted by dealerships, people are resorting to fixing it themselves, like in this video: https://www.youtube.com/watch?v=NxluJqB0gWU This is dangerous. This part should not be breaking so quickly. It should not be allowed that fixing brake light be so expensive by the manufacturer.

The contact owns a 2017 GMC Yukon XL. The contact stated while driving approximately 70 MPH, the vehicle stalled. There were no warning lights illuminated. The vehicle was towed to the local dealer where it was diagnosed that the cam shaft, manifold, and lifters needed to be replaced. The vehicle was repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The approximate failure mileage was 104,000.

The transmission begin to cause the vehicle to shudder and shake. This caused shifting problems that cause the vehicle to be unable to safely drive down the road. We have confirmed with a mechanic that has seen and fixed this same issue multiple times. Causing the transmission to need to be replaced. This is due to the issues that many vehicles like this one that continues to be a problem. This issues has caused my vehicle to be unable to accelerate and has caused it to stop in the road. This is very unsafe and needs to be fixed for all those with this similar vehicle so no one is severely injured.

The contact owns a 2017 GMC Yukon XL. The contact stated that while at a stop, the vehicle hesitated while depressing the accelerator pedal. There was no warning light illuminated. The contact stated that the vehicle was jerking while driving forward at a slow speed. The contact was able to drive the vehicle to the dealer where the vehicle remained. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 110,000.

Transmission failed with no symptons. No indications of potential issues prior. All recommended service checks done with vehicle, oil changes etc... 75,026 miles. Pulled up to a red light in heavy traffic and transmission would not engage. No forward, reverse, or in Low 1. Tried 4 wheel and 2 wheel drive. Nothing. Yukon 2017 XL SLT model.

Not sure if this is the correct raea to notify regarding this incident. I had windshield replaced by Safelite Auto Glass in Cadillc Mi.After the service the technician said he calibrated everything and all is fine. Upon my initial driving after the windshield service the vehicle engine light was flashing and the display was telling me the advanced collision and lane departure warning systems were inoperable. Additionally the vehicle would not accelerate. The vehicle could not be driven safely. I contacted Safelite in Cadillac Michigan the next morning and was initially told the warnings have nothing to do with the service they performed and they do not have to do anything to help me. The manager advised that they ran 3 scans with their equipment and all scans came out good. The manager is saying that confirms everything was OK. I see that as an admission of something being wrong since the technician ran 3 scans. Why run additional scans if all is good. What he was seeing is that the vehicle was displaying warning lights and was not running properly. That is why he kept running scans over and over. Even after 7 scans now they are still saying it's not their problem. Obviously their equipment is incapable of calibrating the new windshield to the vehicle. Additionally they have caused a problem within the engine control module by hooking up faulty electronic device. The vehicle is inoperable. Additionally Safelite knows that they are incapable of performing windshield replacemen

The drivers seat broke and front airbags did not deploy. The seat broke during rear end collision which pushed the seat back so I was no longer able to reach steering wheel or brakes to stop. Went thru on coming traffic to end up on wrong side of road in ditch. Police inspection, insurance inspections, auto repair inspection No warnings.

UNKNOWN 4 times in the past 6 months, while parking the vehicle (turning into a spot, left or right) or slowly turning to pull up to a security code box, the car completely begins to lose power in drive, and has lost power while in drive twice. The dash begins to flicker to the point that you can't decipher which error codes are showing up. Most recently, the Trailer Brake Service message was on before it died. We were not towing anything, did not have tow mode on, or anything like that. The parking sensors were on for all these instances...regardless if we were parking or not. I can't confirm if that is the issue or not. It was pretty dangerous when I was pulling into my parents driveway along a busy road when the car did this before I was completely off the road...with my 3 young children in the back 2 rows. I know the battery is new. I did have the dealer look at the brakes about a month ago, because I felt they were soft. They said they were fine. They and myself checked the reservoir for brake fluid low. Was in normal range. Starter was replaced in March time frame. I feel this is related to the factory trailering system wiring harness or something.

The contact owns a 2017 GMC Yukon XL. The contact stated that while reversing, the brake pedal became hard and unresponsive. As a result, the contact crashed into a guardrail. There were no reported injuries. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the brake assist pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified and a ticket was submitted. The contact stated the failure was related to NHTSA Campaign Number: 19V645000 ( Service Brakes, Hydraulic). The failure mileage was approximately 59,000.

SERVICE TRAILER BRAKE SYSTEM

Brake peddle get hard while reversing at low speeds

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

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.

The contact owns a 2017 GMC Yukon XL. The contact stated that the check engine warning light illuminated on the instrument panel. The contact stated that the vehicle was running rough. The vehicle was taken to the dealer for diagnostic testing. The dealer stated that the fuel injector had failed and the vehicle was experiencing the failure stated in TSB: N182198000 (Engine). The manufacturer was contacted and stated that the vehicle was not included in TSB: N182198000. The manufacturer offered no additional assistance. The approximate failure mileage was 32,000.

I was driving and all my sensors came on stating they needed service including front camera, blind spot notification, lane departure, emergency braking etc. upon parking I exited my vehicle and walked around the rear of my car to find multiple wires hanging down burned from my exhaust. I took my vehicle to an automotive repair shop and not the dealer since it was no longer under warranty. They said they had never seen anything like it. It appeared the harness that holds the sensor module/wires disconnected from the car. It appears to be held in place with some sort of industrial glue. When it failed it was hanging in front of the exhaust and melted all of them. This disabled all of these sensors. I now have to pay for a new harness and to replace all of these sensors. In researching online it appears water intrusion has caused issues in some models and caused these harnesses to fail. I’m wondering if this is the cause even though this model isn’t part of the recall.

Running lights on rear keep failing. This is a known issue with these models.

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.

Just driving along yesterday in my Yukon, and when I stopped another driver pulled up to me and informed me my right rear brake light is not working. Upon further investigation, it comes in and out (sometimes it works sometimes it does not). I had this same issue with my 2015 Yukon, I would have thought GM would have this fixed by now, very expensive fix on my 2015, assuming it’s the same cost or close. Very dangerous to have a brake light out and reduce another drivers reaction time to stop and prevent a rear end collision. Furthermore the vehicle has no indication that a light or bulb is out, a lot of vehicles have that programming, surprisingly this does not.

Adaptive cruise control system is not properly designed to recognize vehicles that are adjacent to the traveling lane and not directly in front of the vehicle. When traveling on the interstate with adaptive cruise engaged, we came around a bend in the road approaching an entrance ramp. There was a slow moving vehicle on the entrance ramp which was apparently identified by the adaptive cruise system as being in front of our vehicle in the same lane. The adaptive cruise caused our vehicle to brake violently while still in the bend in the road, which in turn caused us to swerve into the next lane where there was a car traveling adjacent, but just behind us. This was a very unexpected series of events, and could have resulted in catastrophic consequences had the adjacent car been any closer at the time. This is a major flaw in the adaptive cruise system. And it is compounded by the fact that the adaptive cruise system cannot be switched over to a manually controlled more traditional cruise system. This is a severe design flaw with the GMC Yukon. Some of this could be remedied by issuing a firmware update that allows the driver to disengage the adaptive cruise and switch to a more traditional cruise control method. But GMC has no interest in providing this update, even with multiple message board threads talking about the dangers of the adaptive cruise control.

This complaint is not in response to an event. It is a safety issue resulting from a common problem with this vehicle model, i.e.: brake light failure. The tail/brake light LED circuit board has a design weakness resulting in cracking of the board in 2 common locations, resulting in stop light illumination failures, which could lead to rear end collisions. GM has not issued a recall and their extended warranty allowance is inadequate, thereby leaving a significant repair expense falling to owners when the problem is encountered. The proper safety response is for GM to recall all of the vehicles with this style tail light in order to repair the circuit board weakness.

Taillights and brake lights inoperative. GMC knows of problem and refuses to repair vehicle outside of manufacturer warranty (lights failed after warranty period). I have seen SEVERAL other Yukons on the road with NO brake lights or tail lights. Extremely dangerous situation.

Rear LED brake light stopped working. Supposed to have a vehicle lifetime lifespan. i.e. never require replacing. This light assembly was found to be defective in the previous year model and not fixed.

Passenger rear tail lamp/brake lamp failure. This is a known issue with GMC Yukon vehicles MY 2015-2019 with LED tail lamps. Metal within the lamp vibrates loose and cause the brake lamp to fail - thus resulting in no BRAKE Lamps illuminating at braking. This would be the second time this issue has occurred in 4 months, with the previous repair occurring rear drivers side and logged with NHTSA for this issue under 11436519. Opening this case as now the other side (passenger failed) with the EXACT same issue.

Car is shaking when accelerating. Feels like it will cause more damage.

We were on the freeway with my 4 small children. The freeway speed is 75 mph. The car had been jerking and hard shifting for over a week and I had it scheduled with a mechanic. As we were driving on the freeway, it lost total power as cars were going to the left and right around us. I was barely able to get it to the side of the road without being hit. This could have been tragic! I took it to the mechanic and the transmission is shaving a lot of metal (that was in the bottom of the pan). I have had to pay to have a whole new transmission redone. This is absurd with a car that is only 4 years old.

LED Taillight failure REAR DRIVERS SIDE. This seems to be a common occurance amongst GMC Yukon Denali XL, where the circuit housing for the LED board begins failure with fissure within the electrical contact points. The fissure soon erupts causing a shunt within the LED semiconductor and causing the brake lights to cease functioning.

Driving on city streets at approximately 45-50 MPH the transmission began shifting erratically and made significant squealing noises. After stopping, the transmission could not be shifted to another gear and was stuck in drive (D) for approximately 30 minutes. After evaluation from a professional auto mechanic, these transmissions were equipped with the incorrect fluid type from the factory that has since been taken off the market. The transmission needed to be replaced at ~99,000 miles.

There is a known issue with the wiring harness that warns the driver by vibrating the driver's seat. The original wiring harness will short out causing malfunction of the safety feature. The wiring harness has been redesigned to correct the defect, yet GM has not issued a recall. The safety feature is an important factor in the operation of the vehicle and when this feature does not work property, safety is compromised.

Brake lights are going out due to cracking in the LED strip. Slight jars to lights will make them work for a short time.

1) LED tail-lights fail intermittently - this is a known problem GM does not proactively address unless customers complain repeatedly. Puts driver and passenger in danger. this began happening at 25K miles. 2) AC condenser fails - GM will not address as part of a broader recall despite extensive late model customer complaints. This put passengers in danger on any road trip across desert terrain. GM has been unresponsive despite numerous calls asking for resolution. This occurred at 36k miles. 3) Electrical failings - numerous electrical failings - from entertainment system (at 10k miles), starter motor and internal lighting - all failing at 36k miles. NHTSA must take a look at these manufacturing defects - they are putting customers at risk!

Led lights are malfunctioning on my 2017 Yukon xl. causing my brake lights to flicker and then go out completely. I've been pulled over and almost hit from behind due to these lights not working correctly. they have to be replaced by completely removing and replacing the entire light fixture for the high cost of 800+. they are not built to be fixed, just replaced. What's worse is that replacing them only buys you a little time before those again go out. its unsafe and puts my family at risk daily.

The vehicle is misfiring and rough idling while driving. This vehicle has four of the eight fuel injectors misfiring while in operation. Although the dealership only diagnosed two of them I took it to another shop who diagnosed that 4 and 8 are also misfiring.

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 XL. The contact stated while driving at various speeds, the contact noticed that the passenger rear tail light was inoperable. The contact stated no warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed with the tail light unit needing to be replaced. The vehicle was not repaired. The contact was relating the failure to an unknown recall. The manufacturer had not been informed of the failure. The failure mileage was approximately 106,632.

Passenger side brake light goes in and out and often time stays out. I have read about numerous other people dealing with same issue as it is a manufacturing/quality issue. This is very dangerous. GMG apparently puts the same faulty brake parts back in car while under warranty then when the issue arises again when not in warranty sell customers a pricey part that actually works. Again, very unsafe and terrible business practice as well.

ABOUT 500 MILES PAST THE ORIGINAL POWERTRAIN WARRANTY OF 60,000 MILES, THE TRANSMISSION FLUID TEMPERATURE SENSOR FAILED. I KNOW THIS BECAUSE AN ENGINE LIGHT CAME ON DISPLAYING P0700 AND P0711 AND THE GAUGE ON THE DASH IS ERRATIC. I DID RESEARCH, AND THE TRANSMISSION FOR THESE VEHICLES MODEL GEAR 2015 AND 2016 HAVE SEVERAL ISSUES INCLUDING THIS ONE AS OUTLINED IN SPECIAL COVERAGE N192291660 WHICH EXTENDS THE COVERAGE FOR THIS ISSUE TO 120,000 MILES. IF GMC HAS THE SAME ISSUE WITH THE PREVIOUS YEAR TRANSMISSIONS AND KNOWS ABOUT IT ENOUGH TO ISSUE A SPECIAL COVERAGE, THEY SHOULD DO THE SAME FOR THE 2017 MODELS.

PASSENGER SIDE REAR LED BRAKE LIGHT HAS STOPPED WORKING. IT DOES NOT LIGHT UP.THIS IS A PROBLEM THAT HAS OCCURRED IN THE 2015 AND 2016 YUKONS. I WAS INFORMED BY A FELLOW MOTORIST THAT MY BRAKE LIGHT WAS OUT. THE REPAIR IS ESTIMATED AT $850.00 AS THE WHOLE REAR LIGHT UNIT MUST BE REPLACED.

WHILE SITTING AT A STOP ON A 9DEGREE INCLINE BEHIND ANOTHER VEHICLE I STARTED TO ACCELERATE TO MOVE UP TO THE STOP SIGN. AS I PRESSED ON THE ACCELERATOR THE ENGINE RPM'S INCREASED BUT THE VEHICLE DIDN'T MOVE AS IF THE TRANSMISSION WAS NOT ENGAGING, THEN WITHOUT WARNING IT JERKED FORWARD. I HAD TO APPLY THE BRAKES TO KEEP FROM HITTING THE VEHICLE IN FRONT OF ME. I HAVE ALSO HAD PROBLEMS WITH THIS VEHICLE TRANSMISSION SUCH AS TRANSMISSION FLUTTER, HARSH SHIFTS IN LOWER GEARS, ETC ETC.

BRAKE LIGHTS WORK INTERMITTENTLY. VERY DANGEROUS! PASSENGER SIDE BRAKE LIGHT, STOPPED WORKING COMPLETELY, THEN CAME BACK ON.

INTERMITTENT FAILURE OF ONE BRAKE LIGHT WHILE MOVING. VEHICLE HAS ONLY 38000 MILES. THIS APPEARS TO BE A COMMON COMPLAINT (JUDGING BY CAR FORUMS). I UNDERSTAND GMC MAKES AN IMPROVED VERSION OF THIS ASSEMBLY. GIVEN THE POTENTIAL SAFETY ISSUE, THIS SHOULD BE A RECALL.

CAR STRUGGLED TO START WHEN I STARTED IT. IDLE WAS/HAS BEEN REALLY SHAKY. ENGINE LIGHT CAME ON. I GOT A DIAGNOSIS FROM 2 COMPANIES FOR MY ENGINE. BOTH SAID I NEEDED TO REPLACE ALL 8 FUEL INJECTORS. GMC HAS AN EXTENDED WARRANTY TO COVER THESE ISSUES, BUT IT IS NOT AVAILABLE FOR MY STATE OF UTAH. HERE IS THE CODE FOR REFERENCE FOR YUKON #N182198000. MY CAR IS A YUKON XL 2017 THAT NEEDED FUEL INJECTORS AT 85,000 MILES! HOW IS THIS OKAY? THE REPAIR COST $1,990.28. THE POWER TRAIN WARRANTY HAS BEEN CHANGED FOR 2016 AND 2017 GMC VEHICLES SO THAT IT IS NOW 60,000 MILES OR 5 YEARS. MECHANICS HAVE REPORTED THAT GM HAS CHANGED THE WAY THEY ARE BUILDING ENGINES IN ORDER TO REDUCE COSTS, BUT IT APPEARS THAT CONSUMERS SUCH AS MYSELF ARE BEARING THE BRUNT OF THE COSTS. I WOULD APPRECIATE IF THE EXTENDED SERVICE WARRANTY COULD BE EXTENDED TO ALL STATES IN THE U.S. VS. THOSE WHO HAVE MANDATED IT BECAUSE OF LEGISLATION OR LEGAL ENFORCEMENT.

PASSENGER BRAKE LIGHT IS INTERMITTENT. CLEARLY ISSUE WITH THE INTERNAL ASSEMBLY.

THE NAVIGATION AND INFOTAINMENT FAILS ON A REGULAR BASIS. CANNOT USE TOUCH SCREEN WHEN IT FAILS. FLORIDA DEALER SAID NOTHING WRONG. THE SCREEN WILL TURN TO A CLOCK WITHOUT TOUCHING IT. CANNOT USE NAVIGATION ON MANY DAYS. HAD TO LOCATE A NEW DOCTOR AND THE NAVIGATION FAILED! HAPPENS WHEN STATIONARY OR IN MOTION. THIS STARTED IN MAY 10, 2018 THROUGH TODAY, FEBRUARY 17, 2021. IT IS ONGOING DAILY.

MY VEHICLE TRANSMISSION WENT OUT MOTOR MOUNDS WENT OUT AND SEAT STOPPED WORKING AT CONDENSOR WENT OUT. AND A FEW OTHER THINGS. SUV IS A 2017 WE HAVE ALREADY SPENT OVER 11,000 IN 2 YEARS FIXING IT NOW THE AC IS 2400 TO GET FIXED.

MY 2017 YUKON IS EXHIBITING THE EXACT SAME BRAKE BEHAVIOR AS THE BELOW COMPLAINT, BUT MY VEHICLE IS NOT ELIGIBLE FOR THE RECALL FOR SOME REASON. NHTSA CAMPAIGN NUMBER: 20V603. GM'S OWN NUMBER FOR THIS RECALL IS N202300860.

BRAKE PROBLEMS WHEN STARTING BRAKES LOOSE VACUUM PRESSURE STILL NO FIX AFTER RECALL. 2ND CHECK ENGINE LIGHT CAME ON AT ABOUT 36,500 MILES FUEL INJECTORS DEFECTIVE 3RD TRANSMISSION PROBLEMS VALVE BODY DEFECTIVE PAID OVER 85,000 AND THIS SUV ITS NOT WORTH IT DEFECTIVE ALL DEFECTIVES UNDER 43,000 MILES
