Had a great experience and felt well informed about my F-150 EcoBoost repair options for a coolant leak that caused the engine to overheat. I wasn’t feeling my best while facing the consequences of my truck requiring major repairs. The detailed estimate broke down every cost, from clips and hoses to labor, so there were no surprises. My questions were welcomed, and they took the time to explain what to expect. The staff and management were friendly, knowledgeable, and genuinely helpful. I especially appreciated the straightforward, low-pressure approach compared with some of my past dealership experiences. Highly recommend!

I had to tow my vehicle into Tristar at 4pm the Friday before a holiday weekend. I was stranded in the side of the road and didn’t know who to call so, after a brief google search, I called Tristar. They let me know I’d could have my car towed over and it could stay over the long weekend but that they’d get back to me with an update as quickly as possible upon return from the holiday. As promised they did get back to me and let me know that the situation with my car was something that was actually covered by the maker of my vehicle via a class action lawsuit / extended warranty fix (my car is 1.5 yrs out of manufacture warranty). They told me to go ahead and make an appt with a local dealership and let me know exactly what to ask for re: this extended warranty. Additionally, they didn’t charge me for the diagnostic time it took them to identify the situation. I’m incredibly appreciative of their responsiveness and honesty in a moment that was very unexpected and stressful. They absolutely have my business from here out!

I have had a couple recent repairs here including the catalytic converter and brake booster on my ‘98 Tacoma. I’ve been impressed by how responsive, timely, knowledgeable and professional the shop owners are! Thank you for all the high quality work you guys have done! It is much appreciated even though the issues have been unanticipated. It’s been a pricey last six months for me with all the vehicle repairs, but I’m trying to keep it running well for at least another 100K miles. 👍🏻 I hope I don’t have to come in anytime soon… :)

My first experience was great! Ken was professional and fast. I needed a new catalytic converter in my 2014 Kia so it could pass the smog test - Ken was communicative and friendly. I love that they have a company Uber account so I could be taken home after I dropped my car off.

Ken & Zac got me in quickly, diagnosed my issues, and got me back on the road tootsweet - pardon my french. (They even laughed at my corny jokes! Thanks, guys...😇) My problem turned out to be much less serious than I thought, and they were in contact with me the through the entire process. AND they got me a rideshare to and from! If you want a shop with friendly, reliable folks, you won't go wrong with TriStar!

TriStar Automotive began with an oil change. Most recently I received more service to my car. It needed the attention and TriStar Automotive provided exceptional service. I would highly recommend TriStar to anyone looking for quality, honesty, and integrity.

I needed to have my Exotic car's DMV exhaust certification renewed. The car is an 1988. I have quite a bit of angst when every two years the certification has to be renewed. I took the car to TRISTAR. They were WONDERFUL!! They felt my concern. The car passed with flying colors, twice at this time! The people who own/work at Tristar are master mechanics! They were kind enough to give me a referral for an excellent Exotic car repair shop. Since moving to Sonoma County eight years ago I have been in convulsions on where to take my car for engine repairs. Tristar's recommendation was another star on their rating. They should receive 10 stars!!!

Increase the longevity of your vehicle with routine maintenance

Engine Air Filter & Cabin Air Filter 
Your automobile uses filters to clean the air and fluids it depends on to run efficiently. Over time, these filters can become worn, clogged, and ineffectual. They need to be replaced by ASE Certified technicians at Tristar Automotive to ensure your engine and cabin are kept clean from debris and particulate matter. It’s fast, affordable, and extremely effective!

Fuel Filter
The fuel filter in your car or truck plays an important role in keeping particulate matter from reaching your carburetors or fuel injectors. When the filter becomes clogged it can limit the fuel that reaches your engine and cause all kinds of issues with performance. Our fuel filter service includes a visual inspection of your old filter and replacement if necessary. Get more performance, better gas mileage, and the top-rated fuel filter service at Tristar Automotive.

Engine Coolant Level
Maintaining the proper coolant level in your vehicle is an important piece of the automotive maintenance puzzle. It ensures your car or truck is always operating within its tolerances and never suffers internal damage caused by friction. Our ASE Certified technicians will check your coolant levels and add whatever is required to get you back into the safe zone. Come have your coolant checked at Tristar Automotive today!

Various Fluid Levels
Your vehicle depends on a great many different fluids being present in your engine to keep it operating at leak efficiency. If any of these fluids gets low it can cause trouble for your car or truck, so you need to have them checked regularly by ASE Certified technicians at Tristar Automotive. Get brake fluid, power steering fluid, transmission fluid, differential fluid, and more when you bring your vehicle to Tristar Automotive in Santa Rosa!

Hoses & Belts
Your car or truck’s engine contains a variety of hoses and belts that keep your vehicle running smoothly when in operation. These components can wear out from stresses and temperatures long before the metallic components and require additional service to ensure they’re functioning properly. Tristar Automotive can assist you with any of your engine’s hoses and belts with fast, effective, affordable service. Bring your vehicle in to Santa Rosa’s top-rated team today.

Wiper Blades & Windshield Washer Fluid
Windshield wipers lose their effectiveness over time causing reduced visibility when you need it most; like at night during a raging storm!

Should they need replacement we can handle that, too. So, come to Tristar Automotive today for windshield wipers and washer fluid service while you wait!
