I recently purchased a truck and couldn’t be happier with the entire experience. From start to finish, the staff went above and beyond to make the process easy and stress-free. Everyone was knowledgeable, professional, and genuinely friendly. They took the time to answer all my questions, explain every detail clearly, and made sure I got exactly what I wanted. The truck was in perfect condition, and the entire transaction was quick and efficient. It’s rare these days to find a team that truly cares about their customers, but this group absolutely does. I highly recommend them to anyone looking for a vehicle.

Always experience great service when taking my truck here. I feel we've built a good relationship purchasing here and continue to service my truck here. Did experience an inconvenience issue with regards to a recall and no error codes. I scheduled an appointment online to address it, but when I drove in there was no recall attached to my truck. I drive from SF to Concord to get it serviced so when its for nothing, it impacts my schedule.

I brought my 2025 GMC Canyon in due to a major whistling noise when driving at freeway speeds and the first service, in the end it turned out to be the windshield which was ordered. I made the appointment to get it replaced and asked for a loaner, which none were available on the day i arrived, not even rentals so i ended up waiting 5 hours at the dealership for the vehicle. I also was informed the visor tint on the defective windshield that I had installed would not be reimbursable. I love the truck however.

Dean P|2019 GMC Yukon

LOL! I feel like this has turned into a bit of a lesson in patience. I’ve been doing business with Lehmers off and on for the past 15 years or so, and while there have been some great people along the way, I sometimes walk away feeling disappointed. Maybe I just expect too much. As a business owner myself, I tend to hold others to the standards I try to maintain in my own company, which may not always be entirely fair. Still, I believe an organization is only as strong as its weakest link. I don’t particularly enjoy being “that guy,” but when I’m asked for honest feedback, I feel obligated to provide it. If I weren’t being asked for my opinion, I would likely keep it to myself. However, since the requests continue, I want to be candid. If someone genuinely wants to discuss this, I’m happy to have a real conversation at any time. That said, if the outreach is simply going to be another instance of a supervisor expressing concern and then going silent when I return the call, that’s not productive for either of us. If someone—preferably Darin—would like to have a meaningful discussion about improvement, I’m available. At this point, it feels somewhat circular, especially given that others seem to share similar sentiments based on reviews I’ve seen. So I suppose the question becomes: what are we hoping to accomplish? I look forward to whatever the outcome may be. Respectfully, Dean 925-570-9188

No pressure, a great price and they even made a 400 mile trip for a dealer trade to get the exact Sierra I wanted. Lehmer's is in its 98th year of family ownership and it shows. The employees are happy and employee turnover is negligeable. I see the same faces year after year. The best!

The only reason I didn’t give it five stars is the length of time it took to get parts other than that the service and the people were fives. Service personnel did a great job in finding the parts that I needed like the truck strut, shocks, and the tires for my car and the pressure sensor that needed to be replaced. All of those parts took much longer to receive than it should’ve been, but again the personnel were top-notch fives in my book.

My truck had a check engine light come on. I scanned the vehicle and a 4021 code came up stating there was a problem with the cat. When I took it in they told me there was an update needed and there was nothing wrong with the cat. Why wouldn't it say something about an update? I should have cleared the code myself and saved $300.

truck was fully serviced ($1600 spent), brought truck home and hooked up trailer headed down road and all warning lights in dash went on so I pulled to the side then the emergency brake locked on and truck would not move, would start then die. I called service rep as I had just left the service center an hour before and he was not very understanding, first thing he said was we did not cause it, but all my research from my phone pointed to loose battery terminal or disconnected abs sensor and likely happened from servicing. Things happen I get that but it was the rude response and indifference that cause the bad experience, if only they service rep had said we'll take a look and sorry for the inconvenience all would be good. Instead I have to have it towed there at my expense, then no call the next morning, I had to follow up, then again no response once they determined a fuse on the battery shorted out and need to replace the fuse box, and they didn't get the order in that day so would not be ready for 2 days. Then no information and just a call on the next day afternoon that it was ready, which was great, but no explanation of the cause or reason.

I had great support from Chico Dixon to locate the vehicle at another GMC dealership. He worked with dealership leadership to work out a trade for the truck that I was looking for. It took a few days and they were able to work out the details. Chico kept me up to date each day as to the progress until it was fully completed. In addition, he worked to also get me a good deal on my trade. Chico was so kind, friendly and up front about everything. I would recommend Chico and Lehmer's to anyone looking for a new GMC.

We were quoted $125 for an oil change but upon arrival told us it was $170 because of the issue with the 6.2L V8 engine. The engine issues are not our fault and GMC changed the oil type to protect a sub par engine. That cost should not be passed along to the consumer. Sounds like an excellent class action lawsuit case.

Richard C|2003 GMC Savana Cargo Van
Confirmed Service Customer
8/21/2026
It took a whole week to get the part to fix the cargo van. I didn't receive as many updates from my service advisor as I would have liked. Emily only called me 3 times with an update. I realize she may be busy with customers, but I would have appreciated a call every business day to let me know, the part is still not here yet, but I was the one who had to initiate the majority of calls for updates. It should not take a week to get the part, especially since she said it would be coming the next day from Los Angeles. ALSO, I made an appointment for Tues Aug 11 at 8:30 AM, but the diagnostic work wasn't even done until the next day. If I make an appointment for Tues at 8:30, I expect the work to start that same morning. Emily told me that the appointment is just for the service advisor, which I find absurd. Don't book more service appointments if you don't have the mechanics to handle them all. Regarding the work completed: it was done well, and our driver hasn't had any issues with the van. He is happy that it's finally back, so work can go on. To summarize: service advisor can use some improvement (put yourself in the customer's shoes... how would you feel if your car was gone a whole week? Wouldn't you want to know the status of the repairs every day?), parts shipping is slow, needs improvement, mechanic: workmanship is excellent. If you don't have enough mechanics, you should pay them enough to keep them because that is where your dealership stands to earn the most money: from the maintenance/repair services customers need. Thank you.

I brought my car in for an estimate on my radiator and amplifier. The price was double the amount I was quoted for by another shop. I had my car towed back to me, and when I got my car it was all torn apart and nothing put back together. I took it straight to Firestone the very next morning at 9am. By noon my car was back on the road with only paying 1800 instead of 3800 for my radiator. Firestone put my car back together and didn't charge me to do it. You failed big time Lehmer.
