GMC Arvostelua 

I’ve tried to contact them by phone and email to resolve an issue with the dealership and they have yet to respond. Have emailed them numerous times over the last 30 days and not a response.

Purchase 2023 GMC Denali love truck with too many issues for me to be happy with my purchase. I made a lot of bad decisions in my life purchasing. This truck is certainly in the top 10 it went through so much oil that they actually had to rebuild the engine I was told that it still is going to go through oil about an quart every 2000 miles. They said it’s normal. I don’t see how that’s normal. Additionally, I have to pay double for my oil change because they changed the viscosity of the oil and I have to buy a premium oil on the market. Furthermore, they did a computer update which I never requested that was done automatically and now my run boards and Radio are messed up and they want to charge me $200 to fix it. All I have to say is that’s a fine How do you do?

Never buy a GMC. It has been a huge waste of money for me. I bought my truck 4–5 years ago and I’m still making payments on it.

When I purchased it, I also bought an extended warranty that was supposed to cover the vehicle for 10 years and up to 160,000 km, including engine coverage. Now that the engine has failed, they are refusing to cover it and want me to pay for a full engine replacement myself.

I have completed all required maintenance and services on time, yet they still won’t honor the warranty. I am extremely disappointed with GMC and would not recommend their vehicles to anyone based on my experience.

GMC is trash made to make you go to the dealership for everything. The engineers should be dragged from their home and horse whipped. What idiots put a starter under an exhaust manifold and catalytic converter. Starters have to be changed as well as the alternator which you have to pull the entire fuse block out to change it. If you mess up well you are up shit creek. DO NOT EVER BUY A GMC

I purchased a brand-new GMC Terrain in the UAE expecting reliability, safety, and peace of mind.
Instead, within 8 months of ownership, the vehicle spent approximately 4 months in workshops due to repeated concerns, including an ABS warning while driving with my family, steering and braking concerns, and a cruise control issue.
After multiple investigations, repairs, software updates, and workshop visits, I was ultimately informed that some of these behaviors are considered normal characteristics of the vehicle.
I continue to pay installments, insurance, registration, warranty, and service costs while having completely lost confidence in the vehicle.
I hope @General Motors and @GMC review this case objectively and help reach a fair resolution.

I leased my Hummer EV from GMC Fresno 2 years ago.

I brought my truck in for the 2nd time for a squeaky wheel. Service said the tires were too worn to drive safely and that they would order 3 new tires, but refused a loaner in the meantime. I have to leave for LA in 2 days and this is my only vehicle.

Service Manager Mike Templeton was condescending and said: “You’re bringing the car two days before a trip and you expect me to give you a loaner??” I told him I felt his treatment was racist. He did not deny it and told me not to come back to him.

I requested to speak to the GM. GM Jarrett Marks came out and was sarcastic and even more rude than Mike. When I complained about Mike, Jarrett Marks supported him and said “Mike didn’t do anything wrong.”

As a covered Muslim woman, I felt targeted, humiliated, and dismissed by both managers. I had to drive home with the unresolved squeaky noise while waiting for the new tires to arrive.

This is unacceptable for a $100k+ customer. I am filing complaints with GM Corporate, BBB, and the California Civil Rights Department.
GMC Fresno is now refusing to service my vehicle because of my review. This is retaliation. I am adding this to my discrimination complaint against GM Jarrett Marks and SM Mike Templeton.

General Motors does not care about their customers at all. I've purchased multiple $100,000 + dollar trucks, cars and have always been a loyal GM customer. Always. My 2024 denali ultimate has been in shop for months. Your engineers say its the worst one they've ever seen. They still havent fixed it they've put thousands of miles on it and continue to give it back broken. Its scheduke for the engineers again this week. And guess what hmc offered me $500 dollars in GM bucks or $1500 certificate towards a new vehicle. This is the biggest joke ever. Ive been making payments on this truck while yall have it and cant fix it and yes ita under warranty still. They replaced so much stuff but wont buy it back because im the second owner. Although I bought it with low miles in 2024. Do not buy from this company take your hard earned money elsewhere. My case manager is a joke. She doesnt reapond. She doesnt even know what's going on ever but is supposed to be updating me. She wont let me talk to anyone else. Truly dont know why they employ her. Im reaching out to every news outlet. Talking to attorneys, I will not let this go.

1. The female mechanic was awesome!
2.The heat was blasting in the waiting room and it was unbearable!
3. The same channel and commercial played for 2 hours straight on the TV!
4. I waited over 2 hours to get an oil change because you sent all mechanics to lunch at the same time. One mechanic was left to do all the work while every chair in the waiting room was full!
After 10 years of going to your dealership, I am considering taking my business elsewhere.

I've got a 2018 GMC Sierra. My dealership I've got a warranty through has been great about timely repairs when needed. Recently my fuel pump and oil pump needed replacing. My truck is not drivable until it gets repaired. It's been over six weeks and I'm still waiting on a fuel pump. My dealership has contacted GMC. I've contacted GMC. I can't get any straight answers as to why it's taking so long to get this part that I need. Timing could not be worse either. We're selling our home and moving 2 1/2 hours away. Not having my truck for this long has cost me so much money in rentals and in gasoline. Not to mention the difficulties of only having one vehicle to share between our jobs and having to kids.

It's unacceptable to make someone wait so long for a simple part. If you can't find the part sitting around somewhere, then you should be making them. This is a good way to lose my business. And you can get I'll be warning other people against giving you their hard earned money of this is how you're going to treat them.

I bought a new 2021 Sierra GMC 2500 diesel. After about 3 years the drivers head light assembly gave out. I thought it was a bulb and thought i would buy a $60 bulb. aah no, try $2200 to get the part and replace it. Now the other side gave out. So another $2500. You read that right, thats Just short of $5000 for headlights in 5 years. $1000 per year for headlights.... seems excessive?? I tried customer help lines and no help.

3 days after my new vehicle warranty ended which was March 30, 2026 I noticed my front grill was pealing. I brought my car to the dealership where I bought it and they looked at it and told me warranty is done. I opened a claim with GMC and after 3 weeks they called me to tell me they cannot do anything. I am not the first one that has brought this up. It’s a known issue. They offered me a compensation free oil change lol slap in my face. This is the last time I purchase a GMC vehicle.

I bought a 2026 GMC Denali on January 2026.
I had a minor front end accident early January.
My car has been at crash champions since early February !!!!!
Crash champions has NOT been able to get a “rail” part to finish repairs.
I was told by my insurance company GMC is noted as not getting repair parts.
If I would have been aware this was the situation I would have NEVER have purchased a GMC. I would have saved money on rental cars and stress.

I bought a 2024 GMC Canyon and the first few months loved it so much. Then I had issues with the the boss speakers and within a year the water started to leak from the roof . Took it to the delalship and they was giving me hard time to give me a lonar car . Then they finally gave me a lonar car and said the roof drain was clogged after six months the same issue happened and this time they said they could not duplicate the issue. Also the screen got blacked out after the water leak and the delarship could not duplicate the issue. Contacted customer service GMC with the issue and I asked for a replacement vehicle and they said its past an year since I bought the vehicle and they cant give me a new vehicle or refund my money . So after I got my GMC I traded for a Japanese suv which I love so much driving. If you want comfort and reliability dont buy Gmc products . You be having a bad experience and a nightmare. Stay away from that brand. My rating for GMC is zero. My truck has less than 12000 miles and I had the extended warranty which is waste of money . For oil changes I had to drive to the dealership which is an hour away . GMC is the worst with their products and worst with customer service. They just want to play the people and rob money .

Whatever you do DO NOT BUY A GMC UNDER ANY CIRCUMSTANCE. They come with faulty safety sensors which could kill someone. They allow managers of their dealerships to lie and rip off clients. They allow men like Kevin David to treat women poorly and threaten them if they leave an honest review. So steer clear of this company and all their dealerships

Bought a used 2017 GMC Sierra with only 102,000kms. Less than two years later and only 23,000kms, catastrophic failure. Requires a new engine. Absolute trash.

GMC Canada doesn’t care about business ethics and standards. They allow each dealership to make up dealer fees without any oversight. In other words, each dealership can establish their own practices without any accountability. Just be aware..

I leased a 2025 GMC Hummer in November of 2024. In early January I had to take vehicle to dealer with a battery issue. While the vehicle was in for repairs it was stolen from the GMC dealership. The vehicle was recovered however there was $22,000 worth of damage done to the vehicle. The dealer's insurance did cover the repairs however did not cover the contents inside the vehicle. Due to not having parts for repair the vehicle was at the dealership for more than 6 months. I called customer service numerous times to discuss options for them to take the vehicle back and I would purchase a new vehicle. I had only had the vehicle for less than 90 days and due to it being stolen while in their possession I thought it would be fair for them to take it back. I was not asking for anything free nor was I asking for anything that I did not think was fair. Customer service continuously gave me the run around and said the case was under review and they would call me back. They would never call. I would have to call them to repeatedly get the same answer. The case is still pending. After I received the vehicle back, they said the case is closed I have the vehicle now. I have only purchased GMC vehicles for my family, and I based on other family working for GMC. I however would not recommend, nor will I purchase another GMC based on this experience.

This company doesn't care about their customer. I will never buy another GM made vehicle as long as I live.

I purchased a 2025 Yukon Denali xl received 250 dollars toward merchandise.i wanted to purchase weather tech mats at dealership but they weren't in stock.i purchased my vehicle over a hour from my home .so do to free oil changes I would check on it when car was serviced.the voucher was not there.1 was told it had been added back but was not.after several attempts trying to reach customer service.i finally was able to talk with someone and now I was told that the voucher was expired. Very disappointed that gmc would not put weather tech mats in my vehicle for the price I paid for it.its the little things that matter to me no customer service

Aggressive and annoying advertising from the Martin reality group.
