I have spent a year trying to get a brand new 2024 to pass smog. GMC keeps telling me to "just drive it" as there is no other way. In Cali there is another way and the dealer is chaging me $900.00 to do it. The truck has not been road legal for a YEAR!. The dealer still can't get it to reset. The BAR is involved and GMC keeps dicking me around. DO NOT BUY GMC you have been warned.

Just horrible. Broke down on the interstate and couldn't even pull off the road because it just stopped running. Dealership says "no codes" and nothing GM will do to find out what caused that life threatening ordeal. Fast forward to 1.5 months later and I get a warning that my transmission needs serviced and will stop shifting soon. Took it in and now it's out of the bumper to bumper warranty so they won't cover the transmission shifter module that isn't in the power train warranty. Of course, had they fixed it 1.5 months earlier, it would have been under warranty. Also, the advisors on the GM customer service line are simply awful. I spoke to many and none of them had a clue of my issues, and the last one verbally abused me, calling me a child and blaming me for the lack of service I was getting. I will NEVER own anything from General Motors again. Period. No way. I've had better customer service at Dollar General.

I am so sick of Chevrolet products I love how you have parts replaced under warranty then drive 75k miles and the transmission and valve body go and Chevrolet customer service say there is no warranty on those parts and they cant do anything for you I’ll never buy or tell people to buy Chevy i would of gave a zero for my review

I purchased a 2026 GMC Yukon in December for my wife, and within 7 months of owning it my engine is blown. The vehicle only had around 4K miles on it, and it hit catastrophic failure on the interstate traveling 75mph with 18-wheelers behind me and my family. Nearly killed my entire family, and the customer support I've recieved has been dismal at best. They never return your calls and when you call, you always get a different customer service rep. They always say, that your rep is not available, or not in the office. A couple of them were so rude, that they just hung the phone up on my wife and I. Also, we requested a buy back, as we've already been without my truck for over 30 days, and of course GMC denied that. When I say, this has been a nightmare, that's an understatement. I wish Congress would step in and do something about this, as this is ridiculous. Millions of customers are complaining about the exact same issues, and nothing is seemingly being done about it. What is it going to take? Multiple families being killed as they travel in this unsafe vehicles? I caution any customers thinking about buying a GM product to stay far away from buying anything remotely related to GM!

BEWARE — My 2021 GMC Yukon needed a complete engine replacement at only 88,191 miles. My Yukon 5.3L was properly maintained, including regular oil changes, and I have the service records to prove it. When it began consuming excessive amounts of oil, I followed GMC/dealership instructions and completed five oil-consumption tests, documenting approximately 3–4 quarts of oil consumption every 500 miles. I then paid approximately $3,000 for an engine teardown and diagnosis. The dealership found no external oil leaks but documented oil contamination in the cylinders, carbon-packed piston rings, cylinder-wall scoring, burrs, and excessive internal wear. The engine requires complete replacement. This truck is not even five years old and hasn't reached 100,000 miles, yet I'm now paying $15,500 out of pocket for a replacement engine. What makes this worse is my experience with GMC Customer Assistance. I followed the steps they asked me to follow and repeatedly requested calls from management, but I never received those requested callbacks. I bought a GMC Yukon expecting a reliable, long-lasting SUV. After this experience, I cannot recommend GMC based on either the reliability of my vehicle or the customer support I received when the engine failed. I have retained the maintenance records, oil-consumption tests, dealership diagnosis, teardown photographs, and repair paperwork supporting my experience.

My wife and I were traveling over the 4 of July in our 2026 GMC Sierra AT4 3.0 diesel with only 24,000 miles on it. We were over 700 miles from home and 29 miles out of Ellensburg Washington at 5am when our truck went into decelerate mode. No check engine warning or dash notification other than decelerate mode. We were able to pull off the highway within about 1/4 mile. Shute truck down waited for a few minutes looked under hood for anything obvious and found nothing. Started truck back up and the decelerate notice was gone, so put into drive and went 20 feet and notification again. I turned the truck off and could hear a ticking noise this time. Opened the hood up checked the oil and there was no oil on the dipstick. Done some google research and everything I found was not promising. This truck and motor has a bulletin sent out to dealers and has to do with the thrust bearing having issues due to imperfect machining that causes a catastrophic failure of the motor with low miles on it. Even though GM knows about the issue the choose not to do a recall but yet send the trucks to dealers to continue to sale them. We contacted roadside assistance and were told someone was on their way to tow us to the nearest dealership which was in Ellensburg Washington (University Auto Center) after an hour of waiting we were contacted by Roadside saying we were on our own for a tow truck because no one could come and get us. This was a Sunday morning and when we called tow companies not one of them had been contacted. We had Belko Towing take us to the UAC in Ellensburg and drop the truck off. I was at the dealership the next morning at 7:30am when they opened. I was met by a service rep (Rachel) that was the most unfriendly unprofessional person I have ever met. I told her our situation and that we were over 700 miles away from home and had urgent business back home and needed to get out of there and was informed they don't have loaner vehicles and don't help with rental cars. Under the GM directive on this truck/motor and being over 100 miles from home they are to put us in a loaner car or rental at their expense and get us on our way. She (Rachel) also indicated that there were customers ahead of us and she may not be able to get it in to diagnose the problem that day. Again I indicated there was no oil on the dipstick with a ticking noise and most certainly the motor and turbo were blown. She told me that I didn't know that and it could be a sensor that was out. Not likely but I asked if they could at least get it in diagnose it and get us in a rental car to go home in. Again complete refusal from RACHEL. I called GM customer Service and they was no help at all as well. Telling me the rental car and hotel was completely on my wife and I. I went back to the hotel and waited for the call from the dealership saying they would try to get it in and then call me by 11am. I called back at noon time to find out they had ordered a motor and Turbo for the truck and it would be anywhere for 2-6 weeks for the repair to get done. I said I was going to try and get the truck to Hansen Motors in Brigham City Utah where I bought it from. I was told by Rachel that they diagnosed it and they would not release it from their dealership. I own the truck but not sure how that works. My wife and I couldn't get a rental car for two days and was stranded there without any help from the dealership. When asked to speak with the service manager I was told he wasn't there. I called back two days later to get update on the truck and when Rachel answered the phone I asked for the Service Manager and was told that I didn't need to talk to him and when I call in I should ask for her. After going a round about way I was able to in touch with a very professional person named Beth that was amazing and put me in touch with Bryan Swanson the Service Manager. He was much better than Rachel and I received my truck back on August 4, 2026. There were some gaps in communications still but Bryan was much better. I wasn't informed my truck was headed back to Utah until 2-3 hours after it left UAC. Im still waiting on my money to be reimburse from GM and they are being resistant in the reimbursement but Im sure it will happen soon I hope. Hansen Motors in Brigham City when I spoke with Cody their service manager and told him about the situation he talked with Mark Hansen and they put me in a loaner car to use until my truck was. done. I don't have much faith in GM and University Auto Center and quite concerned about my truck. I do know if I owned the dealership in Ellensburg Washington that Rachel would not be working there anymore. GM and UAC YOU NEED TO DO BETTER. Get me reimbursed .

Although we did not purchase a new truck from VonHolzen, we have used them for service four times during the summer of 2026. We live in a very remote location where there are few GMC dealerships. Several of the dealerships that were closer to us had horrible service ratings. However, VonHolzen had good service ratings, so we decided to do get our expensive GMC truck serviced by them even though going to this dealer is approximately a 140 mile round trip commute. The first visit was to diagnose a service parking brake light that came on. This was the best visit as they found the “problem” that would fix our issue. They claimed that we were missing a parking brake pad and the remaining brake pad was in poor shape. I found this odd as the parking brake perfectly held our fully loaded truck camper and truck on a steep incline with no issues. When I returned for visit 2, they “repaired” the allegedly defective brake pads on both sides. This is a big deal on a 2021 GMC 3500 Diesel Dually Duramax as the GM engineers decided to make the repair super complex (i.e. Expensive ). When I returned home (70 mile drive each-way), I saw an oily smoke coming out from one pair of the rear wheels. Upon further inspection with a flashlight, I saw a dark viscous fluid flowing down the outside surface of the inner tire. I was concerned that the vehicle had suffered serious damage, so I consulted with a diesel mechanic that lives close to me. He told me that the vehicle could not be driven as it was unsafe and the wheel(s) very easily could have fallen off. So I had to have it towed back up to this dealership. This was alarming not only because of the potential serious damage to the drive train but the possibility of a crash during my drive home. The towing bill was also concerning as the tow fee for this size truck was $560. The truck was towed back to the dealership and after examination, the service manager claimed that the damage was not their fault. He said “you just had bad luck” and quoted a repair bill of $650. I again consulted my local diesel repair mechanic (who is licensed to perform safety examinations on diesel trucks for a large international company) and he told me that in his opinion, the mechanic at the dealership did not perform the required service correctly. My wife and I consulted a different GM dealership and got a similar answer. Armed with factual information, we returned to the dealership and presented our case for them to cover the repair costs and towing. After meeting, with the owner of the dealership and the service manager, the dealership relented and decided to cover the cost of the repairs and towing. Upon concluding this visit we drove the truck home. About one week later, the service parking brake light came on again. So I had to make another 140 mile round trip trek to get the issue resolved. The service manager was visibly not happy to see me again which made me feel uncomfortable. When the service was completed he met with me in is office so no one else could hear the conversation, charged us $186, told me they reset the warning light, and informed us that their technicians do not like us and that we should never return for service. On the drive home, the warning light was at least finally out. About one week later, the service parking brake light came on again! Since I no longer had a dealership to go to, I again consulted with our local diesel mechanic. He looked up all of the codes and found that they were identical to the codes that caused a GMC major recall several years ago. He gave me a number at GMC to call to discuss our concerns directly with GM engineers. I called this number and emailed printouts of the multiple error codes to them and was issued a GM case number. About one day later, a customer support person called me and said that there was nothing GM would do to help me. She said that my issues were not part of their recall and would not discuss the code similarities with me. She said that she was not allowed to discuss details and that GM was not responsible. So, after about two months of down time with my truck, over $2,000 of out-of-pocket expenses, driving a truck with defective repairs that could have injured or killed us, being told that we should never return to VonHolzen, and GM effectively saying, “Hey dude, you screwed up by trusting in us!”, we are completely dissatisfied with the VonHolzen dealership and GM. We will never return to VonHolzen and we strongly warn others to avoid this dealership. We are also considering selling our defective truck and will absolutely never purchase another GM product again!
