In June, I had a cooling hose replaced and front breaks there also, but they didn't install the hose clamps properly and caused fluid to continue to spray all over my engine and under neath my car, by july ( a few weeks later) something was dragging under my car and I went in (kinda freaked out, seemed dangerous) but LouLou said they were at lunch and to come back in an hour- (a few people sitting in the office eating) .... so I came back in two hours BUT it looked like tHE mechanic and the Lady were leaving and the lady told me to come back the next MONDAY, very dismissive , but then the man got out of his car and ripped the hanging part out from my car and said it should be fine, .... I was stunned. It was 3:30 on Friday afternoon- and front desk girl wanted to go home- dismissed me again. NOW 2026, I got a new mechanic, of course..and the new mechanic said there are several issues including the battery and under my car there is a small hole in a hose which caused a slow oileak and splashed OIL under my car because there was no cover.... Leaving it exposed to road debris. My car is older but I have taken it in anytime I had the slightest issues. But now $5k later it's in worse shape than ever and would be thousand of dollars to clean and repair all these issues. My car is the shop again, Again because my battery- so Today- I called Sonoma auto to check the warranty on the battery they installed and got nothing but rude helpless answers from the front desk person. . Sh treats me like I annoyed her. Except, I'm a paying customer. Not there to make friends with LouLou. She's rude or she's just covering for the faulty services I received. Or both- sometimes, just taking reasonability for action is all a person needs to hear. But being meet with more dismissive behavior will only add fuel to the fire. Take responsibility, be accountable and treat customers like customers.

They provided me with a detailed estimate for the work and followed up with an illustrated report showing all the stages of the work upon completion. The repair bill was fair and reasonable.

I very highly recommend Coogler's for all your automotive maintenance and repair needs.

I trusted them on their diagnosis. So, flash forward to 2025.... today, I was driving down #StoneyPoint Road, and this dude in a White Nissan Van pulls to the right, into the bike lane.... and then makes an amazing left U-Turn in front of me. OMFG! I have never - NEVER ever hit the breaks and horn So hard!! And when he looked out his window at me, he never as much as acknowledged me. Screeching, tire smoke and noise later, he kept going. I am SO grateful that the team at TriStar Automotive helped me with the breaks on our car. Because I seriously see our car getting totaled because of this d-head.
