I had a very poor experience at the Firestone on Hamakua Drive. I paid Firestone $449 for a power…read moresteering service and $148 for a coolant exchange. Shortly after, I found power steering fluid leaking onto my driveway. When I brought it back to Firestone, they attempted to quote me an additional $900 for a new power steering pump, which I suspected was inaccurate. I brought my vehicle and the Firestone invoice to TENN'S on Keolu Drive for a second opinion. They correctly diagnosed the issue as two leaking power steering hoses, which they promptly replaced. My steering is now perfectly normal with no leaks. Furthermore, TENN'S inspected my coolant system and realized Firestone had failed to refill the antifreeze after flushing it. TENN'S pressure-tested the system and correctly topped off all fluids. I am sharing my experience in this post to prevent others from being misled into paying for poor or unnecessary services.

It's been a couple of years since I've brought my cars here, since I've been doing my own repairs…read moreand maintenance, but a safety check is something I can't do on my own. They're usually pretty accommodating, but when I drove in for my a few weeks ago for my online appt, they told me that it would take about 3 hours before they could get to it. Since I couldn't wait that long, I scheduled another appt, for today (20 days later), at 2pm, and they said they could get to it right away and be done in an hour. The actual service here is okay (not great), but they're fairly proficient in expediting the service, once they get to it. One thing that shocked me, was how much the showroom degraded. It used to be a rather clean and convenient place to relax in the past (for a tire service shop). I can't believe they let the floors get this bad. They were covered with dirty scuff marks, and they removed the little coffee table, and the TV wasn't working. Just from a business standpoint, as a customer, when I see how dirty the sales showroom is, it makes me wonder how much care they put into their actual repair service. I'm glad I'm just here for a safety check.

Tenn's absolutely saved the day for me! I originally took my car to the Firestone on Hamakua Drive…read morefor a power steering fluid change ($449) and a radiator coolant exchange ($148). When I got home, I noticed power steering fluid leaking onto my carport and saw the fluid level was at the absolute minimum. I went back to Firestone, and they told me they hadn't actually changed the fluid, but rather replaced a leaky hose. They then claimed the low fluid was due to a bad power steering pump and quoted me an additional $900 to replace it. It just didn't sound right, and I felt they were being dishonest. I took my car to Tenn's for a second opinion and showed them the Firestone invoice. Tenn's quickly found the real issue: two entirely different power steering hoses were leaking. They replaced them, and now my steering is perfect with zero leaks. On top of that, Tenn's inspected my coolant system and found both the radiator and reservoir levels were dangerously low because Firestone failed to properly refill the antifreeze after their flush. Tenn's pressure-tested the system and topped off the fluids for me. Mahalo to Tenn's--they are honest mechanics you can actually trust!

I also got help when my a/c failed and they were able to keep my a/c going without a lot more expense on my part. But then my 2010 PT Cruiser seemed to have some serious problems about 4 months ago --initially a dead battery which was replaced on 10/17/25 --but then my car died again within a month and was towed back to Tenn's with what I was told was an anti-theft problem with the key setting off the car's alarm system. Then my car sat for 5 WEEKS while nothing was done until around 12/23/25. I kept calling for updates every week and would be told by the front office staff that they were "short-staffed" and just needed "another week". I also talked directly to the mechanic (Blake) who told me that the car was actually running but he hadn't had time to really investigate what was going on but that he would be able to set aside a few hours before Christmas to figure out what was going on with my car. In the end, the only thing the mechanic could do was put in a temporary battery disconnect system to bypass the key setting off the alarm when I tried to open the car door or turn on the ignition. Except it didn't really work. I texted Blake right after I got my car home and he suggested I wait longer than 5-10 minutes to reset the battery; I should try waiting 15 or 20 minutes. I waited an hour. I tried the next day and the next. I got my car to work once or twice in the next 5 days. But not after that. Tenn's was closed for the holidays until 1/6/26. There was never a way to leave a phone message and my texts to the number that I had previously texted went unanswered. Eventually, I decided to sell my much-loved car for parts since it wasn't running. Two different people showed up who looked at the temporary battery disconnect lever and they were each rather surprised at how it had been installed since it was 1) on the positive battery terminal rather than the negative and 2) it was loose and so close to the metal frame of the car. Evidently this was a risky situation for creating a spark and potential fire each time I used the car. The Tenn's mechanic said on my receipt that my car needed parts that weren't available from their vendor or the dealership (SKIM and PCM module) but as it turned out, I sold my car to someone who was a very experienced mechanic who replaced the worn ignition and got the car running again. It didn't need the two modules that were recommended at all. I'm still really upset because I don't think the Tenn's mechanic knew what he was doing at all but he never gave me the option of taking my car elsewhere; instead he put in a potentially very dangerous and completely inefficient "solution"; wasted a lot of my time and money but most important of all, he undermined my confidence in mechanics in general and Tenn's in particular.

Six weeks later, the car wouldn't start. AAA towed the car up to Tony's. Tony was there to assure me he would diagnose and fix the problem.
