Review Time
GMC Sierra is the worst truck in the world. Customer service is the worst I have ever witnessed. Some lady named Tykieia claims she is in charge when you ask to speak to someone else. So according to her there is no one else to talk to about my 3 month issue. Her answer is to put in the same failing part that went bad. This is not a fix at all. It is at best a band-aid DO NOT BUY GMC/GM/CADILLAC/BUICK OR ANYTHING THEY OWN. THEY HAVE PROVED THAT THEY DO NOT CARE ABOUT YOUR SAFETY AT ALL. WORST VEHICLES AND CUSTOMER SERVICE I HAVE EVER HAD TO DEAL WITH. IF YOU WANT TO DRIVE SAFELY BUY ANYTHING BUT A GM PRODUCT! NEVER WILL I OR ANY OF MY FAMILY PURCHASE A GM PRODUCT.
I never imagined I’d have to write a review like this, but after weeks of frustration and fear for my family’s safety, I feel it’s important to share my experience.My 2023 GMC Acadia, only two years into its lease, has now been in service four times in one month for the same dangerous issue — a sudden and complete loss of power while driving, even at highway speeds. Each time, the vehicle abruptly decelerates without warning. Thankfully, there hasn’t been an accident yet, but I’ve had my 4-year-old son in the car when it’s happened, and the thought of what could occur if this happens again is terrifying.The dealership has replaced the pedals, wiring, and management system — yet corporate instructed them to replace the pedals again, as if repeating the same failed fix would somehow change the outcome. Meanwhile, communication between the dealership and corporate has been inconsistent and painfully slow. I’ve spent over a week trying to get clear answers, only to be met with silence and excuses.To make matters worse, I was told the dealership could no longer provide a loaner car, meaning my family and I are expected to drive an unsafe vehicle that has already failed multiple times. That is unacceptable.This experience has completely shattered my confidence in GMC’s commitment to customer safety. A company of this size should never allow a known safety issue like this to drag on without resolution or urgency. I’m still waiting for accountability and a real solution — ideally, for GMC to stand behind its product and do the right thing.Until then, I urge anyone considering a GMC vehicle to think carefully about what kind of support they’ll actually receive if something goes wrong.
I purchased a brand-new 2025 GMC Sierra at the beginning of September with zero miles on it. About two weeks after purchasing the truck, I noticed the tires had dry rot on the sides. I contacted the dealership immediately, and they dismissed the issue, saying there was “nothing there” and tried to wipe it off with a wet towel.After getting nowhere, I contacted GMC directly to report the problem and ask for support, but they were unresponsive. I eventually contacted a Firestone dealership, and they confirmed the tires were in fact dry rotted and replaced them. However, I had to pay the installation fee of about $190 out of my own pocket.I reached back out to GMC requesting reimbursement since the tires should never have been in this condition on a brand-new vehicle. GMC refused, stating the dealership told them it was “normal wear and tear” despite the vehicle only having zero miles at purchase and under 2,000 miles when the issue was reported. There's no way a new vehicle with only a few miles, and perfect tread should have dry rotted tires.I am extremely disappointed with both GMC and the dealership in Bunkie, Louisiana. I expected better customer service and accountability, and this has left a very bad impression after purchasing a brand-new vehicle.1 star was generous for both GMC & the Chevy dealership in Bunkie Louisiana.My Resolution Specialist Echo was NOT HELPFUL AT ALL. This was a horrible experience with the GMC, the dealership, and the Resolution Specialist.
My 2023 GMC truck has been sitting in the shop for almost two months. First they said it was the turbo, then the radiator, then the air‑conditioning system, and now they claim the turbo shredded metal and sent it into the engine, so the entire engine must be replaced. Before this, the truck had already lost power; they changed the turbo, and just 10,000 miles later it broke down again, leaving my family and me stranded on the highway. It took them more than two weeks to give me a clear diagnosis. I pay over $1,000 per month for this truck and yet they’ve left me with a Malibu loaner I cannot work with. I’ve spent a lot of money on rental cars and lost income.It gets worse: two months after buying it, on a trip from Florida to Virginia in 2023, the brakes failed completely; the shop never figured out why and didn’t fix it. While the truck was at the dealership, they even hit it and dented the fender. Most frustrating of all, GMC has not reached out to me—I always have to call and wait on hold to get updates, and no one has offered any solution or replacement vehicle. After years of buying GMC products, my trust is gone.This is my personal experience—I’m not exaggerating. There are also public reports: in May 2025, General Motors recalled nearly 600,000 trucks and SUVs from model years 2021‑2024 because manufacturing defects in connecting rods or crankshafts can cause engines to failcbsnews.com. Consumer protection lawyers note that 2020‑2024 3.0 Duramax diesel engines have suffered turbocharger failures, fuel‑pump defects and emissions issueslemonlawfirm.com. If you own a GMC truck from 2020‑2025 built in Mexico, please have it inspected so you don’t risk your family’s safety.
I would leave zero stars if possible. I wish people would not purchase GM vehicles, they don’t care about their customers or their safety they did not want to help me at all just kept telling me the vehicle was operating as intended. I guess I didn’t get the stop option in my 2024 Terrain, and it was intended to drive me into a bush. I will never buy GM again.
Bought a brand new 2024 3500 Denali, the truck has been breaking down every 3 months since. The most recent breakdowns were in Texas and Colorado. Truck broke down in the Dallas area, transmission completely failed, could not get to Vegas with my haul. Went to 5 dealerships in the area, some were closed on Saturday, some were open with one guy behind the service desk doing nothing. I was told that no technicians were on site and that they will re open only Tuesday. No dealership was able to provide me a courtesy vehicle as well. I still haven got any refund and compensation for that major break down (travel expenses, heavy truck rentals…) I picked up the truck in Texas, the very next day the transmission was acting out again but I was able to make it to Las Vegas. Stopped by my dealership regarding the issue, was told that the truck needed to be driven for a month so the transmission could synchronized with some modules and sensors. After a month I went to Colorado, transmission failed again and the top of it, there is a also a big leak underneath the engine, the master cylinder leaks as well…the truck is just falling apart. Took the truck to the nearest dealership in Denver, was told they will look at it in 7 days….then a few days later got a phone call from them to tell me that they won’t look at the truck for weekS… unbelievable!I called the GMC customer service and got the truck towed to another dealership that was supposed to look at the truck on Monday…. then same BS, got a phone call about three weeks ago to letting me know that they will only look at the truck on the 8th….Haven’t heard from the dealer since so I called today to check in on the repairs…. The Dealership can’t find my truck !!! They never had it ! The truck is nowhere to be found, called multiple dealerships, GMC towing assistance, GMC customer service… nobody has answers and they just don’t care.I am still trying to get compensation for the breakdown in Texas, trying to get compensation for the breakdown in Colorado, trying to get my truck repurchased and now trying to locate my truck… it’s just been a nightmare.My case manager Allie is incompetent, she sounds like she is 12 and just apologized on the phone in repeat mode, I think she is AI !GMC is supposed to be the top of the top…. Well it’s not !It’s time to lawyer up
I want to share my experience with roadside assistance through GM, 2023 Silverado zr2, 6.2L engine leaves my son stranded on hwy, told multiple times tow on the way, Just to be told 3 hours later no one is available. It did get towed 6h after the initial call forcing us to go pick them up an hour away, ruining all our evenings. On top of that because the dealer i purchased it at was a bit further then the closest dealer about 35km more they wanted to charge that at about $135. Money not the issue for me but the complete lack of customer service and car to waste all our time sure is. On top of this we put in a claim with customer service about 2 weeks ago with a logged customer reference number (CI.....) and told someone will call us back in a couple days. I guess a couple in GM world is different then mine, but completely rediculous how much the customer service is lacking. Even the supervisor after 3h could not solve anything. Time for GM to credit all customers for this service and just discount vehicles vs offering a service that clearly does not help you when you need it.
Had purchased a new 2024 Canyon, and it was simply amazing. Never had any problems with it in 1 year of ownership and about 9K miles on it. Wonderful truck. I wanted to go back to an SUV, so I traded it in on a 2025 Acadia AT4. So far, with 1700 miles and a few weeks in, it's also flawless. I haven't anything to complain about. Everything works, everything is nice and I feel like it's simply the perfect vehicle for me needing legroom and space so as not to feel claustrophobic. It has plenty of power, it gets 20mpg around town in AWD mode and 22mpg on the highway in AWD mode. Simply nothing to complain about. Now, I have heard and seen reviews about both of these new vehicles and have concerns about writing a review without any issues to report, as I hope it's not a jinx and I end up having issues. But I waited a year and the Canyon was flawless. Never owned a new car without any issues before. Hoping the Acadia turns out to be the same way. I have had good luck with the GMC and Buick brands in the past, two Encores, one Terrian, one Envision, etc. All of those were cars that just ran without issue as well. I'm hopeful that things continue on as they have, and that things continue to work well. I know that all cars have had issues, a big name hybrid SUV I bought new in 2020 had a need for a new steering rack under warranty in the first 3 months, and a new fuel tank in the first 6 months. So as to say no matter what it is these days, there are cars that need work and as for the solutions, I'll wait to pass judgement on GMC until I see how they perform if something bad happens. The simple service stuff like oil changes and inspections have been fine.
