I bought the vehicle in October 2024 ever since then I have been trouble with the differential, the automatic starter doesn't start the vehicle unless you are at least one feet away from the vehicle. I drove to work when I got off and got in my vehicle my check engine light was on. The vehicle was saying there was an issue with the battery, antilock braking system. I bought an extended warranty up to 150,000, I currently have 63,400 on my vehicle. Empire Buick GMC of White Plains has not been honoring my warrantee, I had to rent a car to get back and forth to work because of fear of riding the NYC subway.

I was driving my car and it started making "clanging" and "banging" noises and jolting/jerking forward. It was scary to drive because of the noise and the jerking foward. I was afraid that my car was going to just stop working, I would get stuck/stranded somewhere or my car was going to blow up. I brought it in to the dealer two times. The first time they thought it was the battery so they replaced the battery but that didn't fix the problem. The second time I left it there for days and they told me that I needed a new transmission. The problem was reproduced and inspected by them. There were no warning lights or messages prior to the failure. The problem started on approximately January 6, 2025. Online, I have read from other sources that 2017 - 2020 GMC YUKONS are know to have transmission problems. My car only has 58,000 miles on it, has been serviced consistently, and should not need a new transmission at this low mileage point.( 150,000 to 200,000 is the norm for transmission replacement)

I am submitting this complaint regarding a persistent and significant transmission issue with my 2017 GMC Yukon Denali, which I purchased in June 2024. The transmission has been malfunctioning, causing the vehicle to jerk and hesitate, particularly during acceleration. This component is available for inspection upon request. Safety Concerns: This issue poses a serious risk to my safety and the safety of others on the road. The jerking and hesitation during operation can result in delayed acceleration or unexpected speed changes. These problems have occurred while merging into traffic and driving on highways, creating hazardous situations where immediate and reliable vehicle performance is critical. Reproduction and Inspection: The problem has been reproduced and confirmed by an independent mechanic who inspected the vehicle. The diagnosis identified a transmission malfunction, which appears consistent with reports from other owners of GMC Yukon models. However, the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. Warning Symptoms: There were no warning lamps or error messages displayed prior to the onset of the issue. The jerking and hesitation began soon after I purchased the vehicle in June 2024 and have progressively worsened over time. I have discovered that GMC has issued recalls for similar transmission issues in later Yukon models (2021 and 2022). However, despite widespread complaints, earlier models like my 2017 Yukon Denali have not been included in these recalls. Given the safety risks associated with this transmission defect and the frequency of similar complaints from other owners, I urge the NHTSA to investigate this matter. Prompt action is essential to ensure the safety of drivers and passengers in affected vehicles and to hold the manufacturer accountable for addressing this defect.

I was taking my client to school. I stopped at the stop sign. When I pushed gas pedal to go, my truck did not go, it strained did a big jerk then went. The next morning it did the same thing & later on that day, it did it again. Two days later I had to stop at red light. When the light turned green I pressed the gas pedal & nothing. It did not go at all. I turned the ignition off and back on twice & put it in drive still did not go but was slowly going backwards. A by-stander stopped to assist me getting my truck out of traffic.

This happened 5 years ago but I never reported it. GMC 2017 Yukon. I put my SUV in park, and entered and exited it several times while parked in my driveway. When I went to grab my purse (standing at drivers side door, reaching for purse on passenger seat) the car rolled. I was on a sloped driveway. The car rolled backwards, and I tried to jam it into park more strongly, but it just made a grinding noise and kept going. I was knocked over by the car door, pulled under the car and ended up having my legs run over by the car. I sustained injuries which affect me to this day. I was transported to the hospital by an ambulance after a 911 call, so I presume there is a police report. I was injured and dazed. This happened on [XXX]. I am only reporting it now since I never thought about doing so before I read an article today about cars being recalled for this problem. If other people have my model of car and this is a problem, I would want them to know. I was thinking maybe I hit the gear shift with my purse and knocked it out of park, but this should not have happened without the brake depressed. I was standing next to the drivers side door when this happened. I did have the car taken to the dealership to be examined, and they said it was ok, but could not really explain how this happened. I still have this SUV but am very cautious about any situation where the car could roll when in park and cause injury. The car crashed into a tree and that stopped the rolling. Has there been other reports of this happening with this model of car? I would like to know, because if there is a problem that has come to light in this, I will get a different vehicle!

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.

We took the car into the dealership and complained about the AC and the vehicle being new and they said it was a common problem with this vehicle and offered 10% discount.

Air-Conditioning condenser failure (Special Coverage Adjustment 173326 Air Conditioning Condenser (Combi-Cooler) Refrigerant Leak) According to GM they say my VIN is not on the list...however, I'm having the exact same issue on my 2017 Yukon with 38k miles on it.

My husband and I were driving down the freeway with our three children when without any warning, we heard a loud explosion and what felt like something hit our vehicle. There were no other cars near by. When we pulled off the freeway into a gas station to look at the vehicle the sunroof had a huge hole in the center. The remaining class attached to the vehicle was all shattered. There was shattered class on the closed shade. We didn't know what happened. It was very traumatizing. We thought someone threw something at us or something had fallen on the vehicle. If the sun shade wasn't closed, glass would have entered the vehicle and could have caused injury to us or our children in the back seats.

My car A/C has a leak at the condenser, this is a defect known by GMC, they only extended the warranty up to 60,000 miles and 72,000 on Cadillac, my Yukon actually has 71,500. The repair for the GMC defective vehicle A/C is extremely costly to replace the defective parts and overpriced labor.

While driving, my A/C climate control has failed in 2017 GMC Yukon (milage 78,734). This has caused a dangerous problem when the windshield fogged up and I couldn't see out the windshield almost causing a crash. I was scared to death from this incident driving on I270 here in md. I am both shocked and appalled there is no recall issued and that GM used leaky air conditioners that buckle under pressure in many 2014-2017 trucks and SUVS. Whether it's busted hoses or leaky condensors, thousands of GM owners like me are upset that a nationwide recall has not been issued to repair this dangerous problem. It's such a widespread problem that there's a nationwide backorder for replacement parts. Many of the original replacement parts were discontinued to to the defect. See tsb pie0340. Along with the alleged problems with the compressor to condenser lines, a class action lawsuit says the air conditioner condensers are defective because the materials used to manufacture the condensers are defective. I took it to my local shop to find out my condenser needs replacing and the service tech told me it is not under warranty but have had many problems with the condenser on this make and model vehicle. He also agreed with me that it should be a recall since there have been so many vehicle with the same problem. My dealer wants to charge me $160 just to diagnose this problem, although the dealer acknowledged this problem first noted in bulletin # pie0340 date: Jul 2015. Then they estimate replacement of defective parts to be $2000!! I called GMC customer service case # 9-6360482931 I asked why I was never notified of this problem when I bought this used vehicle and they declined to answer. I would not have purchased this vehicle had I have known of this safety defect. I respectfully ask that you have GM issue a recall.

The rear tail-gate has come down by itself when putting items into or taking items out of the back of the car. It has happened at least six times and without warning. It has happened in our driveway and in parking lots. Vehicle was parked and turned off at the time. This can hurt or kill an adult or child. I'm going to report this to the dealer at the next service visit, but I also wanted to report it here because you are the in charge of the publics safety. There is another individual that has reported this same problem. Thank you!

Hands free rear cargo door opens and closes when people are in danger of being struck by the moving door, without an intentional motion of the foot to open or close the door. The door has closed on me several times while loading/unloading cargo. Brought to dealer but they say GMC has not released part number of a software update.
