Our Reviews

Great customer service, friendly staff. A bit of a wait before meeting with Chris in Finance but understandable because of two customers in front of us. They did what they could to help speed us through given the circumstances, and Darryl was very kind in letting our kids stay in his office during part of the wait so it was very much appreciated. Very good experience overall.

Honest Service Department

Friendly, efficient completion of the work. Thank you Steve and Emily.

I was treated great

Tom was great. Very helpful and friendly.

Very professional and a great job working on my car. Service representatives are friendly and knowledgeable.

Great Service Advisor. The diagnostic work by the technician was quick and fixed the problem.

You guys had my truck for 2 1/2 days, it took 2 hours to fix, I get it that you guys were backed up but I did hear anything till the end of the second day about my truck. Shouldn’t except appointments if you’re that back up…it’s not the first time this has happened

fast and efficient

My truck needed an oil change and to have the infotainment system “recalibrated” according to the error message that occurred as a result of my battery dying. I changed the battery before bringing the truck in. The recalibration seemed to stump the team for a couple of days before suggesting a diagnostic process they needed to charge for. At one point they suggested I take the truck back without the recalibration fixed. We got there, but it wasn’t confidence inspiring.

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.

Emily is awesome!

Got air filter and oil change did not reset the warning signals. Still says he needs new ones.

Courteous and knowledgeable service agent. Easy check in. Work completed on time.

Always have a good experience. I feel appreciated as a customer. The receptionist/cashier is always friendly and fun to talk with.

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.

The job was done to my satisfaction. I was kept informed of the progress.

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.

The Best Ever!!!

Everything was smooth from the check in to the finished delivery. Lehmers always does a great job!

Took car in for major repair, got car back in less than a week. Fast work!!

Great service as always, fast professional and courteous. They even washed my truck.

Friendly staff. Vehicle was ready before time promised.

Always efficient and helpful. Work was done pretty quick as well.

Like all other times for 20 years. Lehmers has great people, good mechanics, and keep my investment(Car) running great!

This place lives up to the 'slimy dealership' reputation. From the sales person who was clearly only interested in selling the car, to the negotiator that wouldn't even speak to me directly- I would never be a repeat customer. The icing on the cake was that they couldn't even through in free floor mats despite buying a $104k car in cash. Take your business elsewhere.

First time at this dealership, great experience! First service, beat expectations

As always, top notch service with a knowledgeable, friendly staff.

Easy to schedule; car done when promised

Completed the work needed and got me back on the road.

Tom M is the Best!

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.

On time service and very courteous personnel.

did a great job

Great as usual. Vehicle was ready on time!

They really care about consumers demand

Everyone that I came into contact with was pleasant. This is the first time that I'm able to say this as a customer of this dealership since 10/2006 when I purchased my truck. Thanks for the pleasant experience!

Always good

Recall was completed quickly, no complaints.

Service manager Tom was great

Overall the finance person and I believe the sales manager were great. Now Chico the salesman, false promises after the sale. Promised something and completely disappeared. After he gave a speech of he’s a man of his word, red flag warning.

Thank you so much Marty!

Very straightforward process. Was in and out as they had communicated and planned.

Lehmer's service department has been my go-to for many years. The service writers are so pleasant they make doing business a great experience. I found the same with the sales team. 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!

Everything was great! Daniel was extremely helpful, he let us drive 4 different trucks until we found the one that we wanted. He was patient and answered all of our questions!

Good

I had to bring my car back 3 times for the same problem. I just found the same error message on my dashboard today, February 18th.

Flawless experience. Needs a tire rotation and oil chance for my truck. Made an appointment, showed up on time out in less than 90 minutes and the they washed the truck. Price was great, I only take my truck to them. Give them a try, ask for Stephanie.

Did a oil change and glow plug issue. Great Service Thank you.

Very Good dealer, everyone was very happy to answer any of my questions and concerns and the buying process when very smooth

Lehmers dealership has always been a respectable place of business over the years for me and my family. The service representatives are friendly and thorough.

Great job

Service was fast & friendly.

Like always Marty explains everything and helps thru a fast and easy way to complete any service appointments. Thank you Marty.

I wish there were more varieties with the interior. I had no choice on the leather, moon roof or upgrading to get the wireless charger

Gerard was very helpful in explaining the various details about our Terrain and the financing options.

All service items completed on time.

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

Best dealer around, super friendly staff and was out in no time. Would recommend

excellent service from emily/always friendly and professional!

Outstanding service and staff. Stephanie is knowledgeable and so helpful when I have my vehicle serviced. Everyone is polite and knowledgeable which makes dealing with vehicle issues so easy.

Staff are great and friendly, service excellent

My vehicle was serviced in a timely manner. Staff were friendly and courteous.

Tom has been my go to guy for years. He knows what we need and makes suggestions to maintain our vehicles effectively. I was glad to see Stephanie move. It says a lot about Lemers mgt.

Great service!

Thanks for finding the oil leak before it became a major issue. Service Advisor. Emily, was very helpful

The service crew is friendly and professional. It sounds cliché but it very fitting

Tom, the service representative, went above and beyond, to address the repairs to my vehicle and work with my extended warrantee company.

I recently purchased a vehicle from Lehmers GMC, and I couldn’t be happier with the experience. The team was welcoming, knowledgeable, and genuinely interested in helping learn about my new truck. They took the time to understand my needs, answered all my questions with patience, and made the entire process smooth and stress-free.

Experience was good from check in to shuttle drop off and pick up.

Tom got my car right in & service was completed quickly.

Friendly always take care of my needs and then some

Excellent customer service. Clean waiting area and service done quickly.

Very nice people in the service department, they were quick and helpful.

Continued great service. Tom Mimiaga is the absolute best service advisor.

Service was excellent. Went in without an appt and the team was able to accommodate and repair a warranty item and a recall

It was perfect. I needed an oil change and a warranty item. Check in was quick, I got a ride home from their shuttle. Truck was ready the next day. It was washed. Great job by Stephanie and Emily.

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.

Marty provided excellent service

My recent experience with service has been excellent and I notice that the entire department seems to be functioning at a much higher level since Stephanie Castaneda has taken over as Service Manager. I would not hesitate to recommend this dealership to anyone in need of quality, efficient and friendly service. Two years ago I did not feel this way, however, due to my recent positive experiences, I am happy to say that has changed.

working with carlos was fast and easy! love my truck!

Just a new battery, But Tom in service , like always he sprang into action and got me a good time to fix the issue. As always.

Humberto was great, answered all of our questions about differences in trim packages and was not pushy, honestly if he had been I would have walked out.

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.

Well I’m not so happy about the service I got. I don’t know why every time I bring my car to get service, there is something that they don’t do.this time they don’t rotate my tires.

A+ service

As always, the service at Lehmer's was great. The service advisor explained everything clearly, and the car was finished on time, for my pick up.

Tom was very friendly and helpful. Everyone goes above and beyond to provide good service.

Had oil change. In and out in less than an hour. Great service!!

Love the love and care I receive every time I bring my car in for service!!

Good service and work completed as promised.

Everything went well from the timing of the shuttle to the service of the vehicle

Great service and advisors as always

Tom is a great service manager explained everything clearly and excellent communication

Emily Is awesome. Always Sets Up My Appointments. Gets Me In And Out Right Away...She Is Awesome....

Very helpful

Excellent Service as always!

Professional, knowledgeable, friendly

Quick

good job.

Lea is a great sales person. She listened to what I wanted in a car& & did an excellent job of explaining everything to me. She was patient in letting me decide what I wanted. I have found all the staff I have been in contact with are very helpful and supportive. Of course the service department is great too. This is my 4th YukonXL & I am very happy with it & with Lehmers.

Everyone was very helpful and eager to satisfy my needs. Thank you

Everything was good expect the comunication I was not being notified when was my car expected to be ready I had to call a few times and leave messages with no return calls.

,Service person was friendly,Price was great, Work done on time

Excellent service and I really like Tom as my service coordinator. If you are at Lehmers, ask for Tom.

Gerald was amazing!

Tom Mimiaga is an excellent service advisor! Everyone I’ve worked with at Lehmers has been great.

Emily went above and beyond as usual!

Excellent customer service, both friendly and knowledgable. The maintenace coupons and gift certificates provided by the dealership can really make maintenance work a bargain. Work was done in a timely manner while I waited and a free car wash was provided as well. Well done Lehmer"s!

Mary is a great service advisor!

Excellent customer service!

Service writer, Tom is great!

Our service advisor Marty was wonderful to work with. Friendly and knowledgeable, Marty made it a pleasure to bring our car to Lehmers for service!

I just needed a lube and oil and a new fuel filter. It was done and my car was ready for pick up in the afternoon.

Defective side mirror was replaced under warranty, truck in good shape.

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.

Great service, accommodated request for quick turnaround

Good response

I have an excellent association with Tom and Emily and I have been having my cars serviced at Lehmer’s for approximately 20 years.

Once Again My Check Engine Light came On And I Contacted My Service Advisor Emily Vanden.. She Advised Me To Bring My Truck In.. When I Got There She Wasn't In Yet.One Of Your Other Service Advisors Asked If He Could Help Me I Told Him My Engine Light Was On. The First Thing He Told Me Was Sorry we Are Overbooked Today.I Asked If I Can Leave My Truck And Get A Rental He Said No There Is A Waiting List For Rentals.They Can Give Me A Ride Home I Told Him I Live In Oakley He Said We Can Drop You Off At BART.. I Said No I Will Wait For My Service Advisor. When Emily Came In She Checked In My Truck And Set Me Up With A Rental Vehicle.. That Is Excellent Customer Service!!!! Emily Is Awesome

Great customer service.

My experience taking my car there for a check-up was very bad.

Always happy with my service

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.

Great service department. Tom Mimiaga always there to help in any way he can.

Very fast and friendly
