Costa Mesa GMC

Bait n Switch. They show SUV at 67k, yet have 4700 in added crazy dealership add ons to the vehicle. Some items you can’t even understand what they are. They are misleading and dirty sneaky and give all car dealerships a bad name. When I search cars… i do not even look close at anything car that says Costa Mesa GMC.

Very complicated and disappointing. I've bought so many vehicles in my time and I've never experienced anything like this. It was as if they were doing me a favor. They made my transaction a miserable experience. I seriously regret going to them. If you are cash buyer they will do everything they can to prevent you from paying cash. They make money on financing your car. They wanted to run my credit and provide them with all my financial details in order for me to pay cash for the vehicle. Never again.

There communication is terrible, they are intermenten , so i have gotten nothing accomplished with them on buying a truck. They have left me hanging.

Very rude and unprofessional! Cynthia was a.rude and uncaring as.they come. Unhelpful and uncaring dealership! I would look elsewhere!

Worse dealer. Came here twice for the same car. First they would sale me the car without the 4700 add-on but we couldn't agree on the price. 2nd time came back for the same car, this time, the price was lower so we agreed on the internet price and do not want the add on. The floor manager said nobody in this dealership would do that. We told him about the person that we talked to last time and he said that person was fire. Lame. Wouldn't trust anything come out of this place salesmen !!!

Another 1 star review for this dealership. I was trying to make a quick lease happen on a $100,000 vehicle, but I was met with passive emails from a member of the sales team. They wanted me to tell them what I wanted my payment should be instead of simply talking price, and they wanted me to show up in person to get the best price. How silly. Then they would get back to me several days later saying dumb things like "Thanks again for your consideration. We really appreciate it" rather than just being direct by saying "is there any way we can earn your business?" I will take my $$$ and business elsewhere. This dealership is a joke.

READ THE REVIEWS before you choose to spend your hard earned money on this establishment. I’ve been texting with a salesman from here for a little while now and was very upfront about what I could afford on a lease in a specific mentioned truck. The salesman advised me in order to get those figures, my manager would be more inclined to make it happen if you are here in person. I drove for two hours and asked for the salesman that was speaking to me. While the salesman gathered my name, zip etc. He came out with the figures, mind you, I had told him my budget was $600 a month, he came back at $1,000 plus monthly on same exact truck I had been texting him about. So, then the back and forth game ensued. I told him, I was very clear to you guys that I could not go over my budget. Then they came back at $699. Which was still $100 over my budget. So, I left. While I got on the road, the salesman called me and asked me if I could meet them at $657, to which I agreed. I sent in my credit application and had them run my credit etc. I came back to sign the wet signatures and the “Closer” came out and flat out told me, “I didn’t know you were in the car business and that you pulled a fast one.” Yes. The closer, whose job is really to capture everyone’s business including whether or not the customer is in the car business blatantly said “you pulled a fast one.” As if I fraudulently attempted to lease a vehicle from here. So, do yourselves a favor and avoid this dealer at all cost. If they treated someone in the business this poorly I can only imagine how they treat their day to day customers.

Awful experience! We called as very serious out of state buyers for a 2025 Yukon Denali Ultimate and they pushed us off “stating they were too busy”. They low balled our trade saying it’s because of how different the CA used car market is compared to other states even though another dealer in CA offered us a reasonable amount similar to where we live. The initial salesman, Fonzi disappeared and we had to call multiple times to get answers basically just to get nowhere. The second Saleman, Erick just relayed useless information from the manager and said there was nothing they could do even after we had a standing pre-qual in their online system. Costa Mesa GMC made us feel unworthy and unwanted of our business. Absolutely shocked and appalled this is how we were treated after attempting to purchase a $100k+ SUV, especially after being loyal to the GMC brand for so many years.

Shut them down. Absolute fraud. Shut them down. Absolute fraud. Shut them down. Absolute fraud.

It was the most terrible experience I've ever encountered. I bought a 2024 GMC 2500 Denali Ultimate for $115,000 with plans to travel the country using my 2023 Airstream Classic. Unfortunately, problems arose when the truck's trailer brakes repeatedly malfunctioned while towing. After several incidents, I found myself going back and forth between the Airstream and GMC dealerships. Eventually, I sold the Airstream six months later because the brakes kept disconnecting without warning, making it impossible to stop safely. I then purchased a new 2024 DRV 5th wheel to ensure reliable braking and avoid dangerous situations while driving my RV. However, during a trip home with the new RV, the brakes disconnected again about 400 miles in as I was descending a long hill with an 18,000-pound trailer. This was extremely hazardous due to the trailer's size and weight. We immediately visited the GMC dealership, who claimed the problem was with the truck. Weeks later, we received a letter from GM about a recall addressing the issue of trailer brakes disconnecting while driving—a problem experienced by many other trucks. I took the truck in for the recall fix promptly. After it was supposedly fixed, we set off again, but 20 miles in, the brakes failed once more on a steep, two-lane road. We ended up in oncoming traffic—it was terrifying, and we barely managed to stop, disconnect the trailer, and head directly to the dealership that had done the repair. I was extremely upset. The dealership suggested pursuing a lemon law claim with GM. I spent a month on the claim, but GM denied it without providing a clear reason, only a brief phone call. I assumed they were trying to avoid liability by not giving any documentation. Frustrated, I reached out to the dealership about my situation, as I had a new truck but couldn't safely tow my RV, leaving me stuck in an RV lot. The dealership informed me they'd coordinate with a GM representative to explore the next steps. I returned the truck for the sixth or seventh time, leaving it for a week. Today, they notified me the truck was ready and concluded the issue was with the trailer, not the truck. I was taken aback by their conclusion, especially since GM engineers had inspected it a second time. My dissatisfaction was evident, but the service manager, Sergio, took offense and told me not to return to the dealership. I bought this $115,000 truck specifically for towing, but the trailer brakes constantly fail. I am utterly shocked by the entire experience. If you're considering purchasing here, beware—they may tell you what you want to hear until you make the purchase, but if something goes wrong and there's a recall, you're on your own.
