My experience at the dealership was excellent from start to finish. Abraham greeted me right away, took the time to understand what I needed, and answered every question with patience and detail. The entire process was fast, smooth, and professional. I truly appreciate his outstanding service and the overall efficiency of the team.

Had to get some warranty repairs done. Jeff took care of all the processing and we were informed about the progress from start to finish. Professional, courteous customer service.

I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

Adam Miller in the service department is the best! He is always very friendly, and makes sure my vehicle and I am well taken care of. It seems that nothing has changed at the dealership since it was sold. I am very happy about this. Thanks again for the great customer service!
2026 GMC Sierra 1500 review
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

On April 6, 2023, I took delivery of a 2023 Yukon Denali Ultimate, which was a SUV that I ordered, equipped the way I wanted it. John and the entire sales staff were great! I have purchased/leased 4 other vehicles from this dealership and have always been treated well. If you want to avoid all of the seemingly normal drama that goes along with walking into a dealership, you need to try this one - you'll be pleasantly surprised.

My first complementary oil change service at Temecula Valley GMC was a wonderful experience. I was greeted fairly quickly and checked in then assigned to Quinn as my service advisor. He explained clearly what was going to take place so I understood exactly what his Techs were going to perform. He provided the estimate estimated time of when it was going to be completed and and actually came in about an hour less, which was great! I will definitely bring my truck back and request Quinn as my service advisor!

Ricky was very professional, knew when to step away to give us time to talk without asking him. Did not give the stereotypical car salesman approach. Highly recommend Ricky if you just want to get the deal done. He understood we came in wanting what we wanted and the OTD price, so the transaction went fast and smoothly

2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

Costa Mesa GMC review
The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want
2026 GMC Sierra 1500 review
This is my first GMC and I absolutely love my Sierra 1500 Elevation. The 5.3L v8 is more than enough to pull my camper, I love the stylish interior and it is comfortable to drive. I also felt with the financing and discount specials this was a great deal.
