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.

7:30 am on a Thursday in Santa Rosa…read more.. My truck broke down on the way to make a delivery... AAA towed it (and me) to Coogler's on a recommendation from a friend who knows these guys. Stressed? You know it! Concerned about the work that would be done and how long it would take and what it would cost? Absolutely! Who isn't stressed out when their car breaks down, and they're going to a new auto mechanic??? Greeting me in the lobby were three of the nicest guys who just got into work and were in a better mood than I was... Things were looking up already... Jeff was my repair coordinator, and he immediately put me at ease and let me know that they would do everything they could to get me back up and running ASAP. I quickly booked a rental truck and Ubered to the rental location to get it and bring it back to swap the goods and get back on track. One of the technicians (Scott maybe?) helped me make the swap (above and beyond? Yup!) Quick communication on Coogler's part with some texts and emails told me they had found the problem and were on the case. Estimated time to repair? End of today or tomorrow at the latest. That's fast, I thought... Good news too because I've got more deliveries coming up. 'Tis the season... Fast forward ~4 hours and I'm getting a call from Jeff telling me my truck was ready to pick up (pun intended). What?!?!?! 4 hours and it's done!!! Got back to the rental shop, got one of their guys to take me back to Coogler's, and was back in my truck at 1:30 pm. Since then, a couple of genuinely concerned calls and emails asking if everything is still going well with the truck. Normally, when I do business with someone, they only call to ask if we can do more business. This was actual follow-up and quite refreshing. Will I work with Coogler's again? You bet I will! And if you've been looking for a dependable auto mechanic who's going to do a good job of both fixing your car AND being pleasant to work with, you should too!
