      Other headlight not placed in at all
      Nathan A.

      I brought my car to OC Automotive Diagnostic to repair a busted headlight lens. From the start, the experience wasn't great--the front desk staff had a dismissive attitude when I first dropped off my car, which already gave me a bad impression. After the repair, I noticed that my headlights were dim while driving at night. When I checked under the hood, I found that one bulb wasn't plugged in correctly and the other wasn't installed at all. It's frustrating to deal with this kind of sloppy, careless work, especially on something as important as lighting for nighttime driving. Between the poor quality of the repair and the lack of professionalism at the front desk, I won't be returning and can't recommend this place to others.

      OCAD is on Whittier Boulevard, across the street from LHHS.

      Everything was excellent. They even picked up my car from my house. I will definitely be coming back.

I got my car serviced about a month ago by this business. One Saturday, my dashboard had lit up with a bunch of lights and it was rattling on the freeway. I was referred to them by AAA and brought my car to the shop after a quick phone call to give them a heads up. In the office, I spoke with Kevin, who kept me informed and updated on the plan. After leaving my car at the shop for diagnostics, I expected to hear back later that afternoon, as they closed a little earlier at 3 PM. However, I didn't hear anything back from them (this is why I removed one star). Since they were closed on Sunday and Monday for Memorial Day, I had to follow up with them on Tuesday morning when they opened at 8. Kevin told me the issue with my car's ignition coils, recommended a tune-up, and ran the numbers, which I found to be a reasonable price. They told me that my car would be ready before the end of the day. I was honestly pretty skeptical, but it was ready before 3 PM! They do take Zelle payments which lowered the cost a little bit. It's been a little more than 5 weeks since the service and my car has been running excellently so far. Thank you JJ Star!
