Monrovia Auto Repair

Friendly and welcoming - seiko and Sergio explain everything clearly and provide updates constantly. I appreciate their comprehensive work!!

thank you

The guys at Seiko are a hidden Gem in and around Monrovia. Previously all service on my Subaru Outback was done at Glendale Subaru but felt service could be a little better. Seiko auto service has proved to be the place. Sergio was very professional and informative throughout the process. I will be coming back for all my car service needs.

Best in the business, honest reliable work.

These guys are great. I never worry about my car not working because they do everything right the first time

I had a mechanic for nearly 40 years whom I trusted with all my cars....(friends and family did too). When he passed, it took me a few years until I found Seiko's Auto Service whom I now trust with all my family's cars.

They do a very thorough job

While the service they did to repair my brakes was perfect and they were straightforward and great in their demeanor, the repair costs were higher than expected.

Was looking for an honest mechanic in the area. Brought my 2010 Prius in for a blown head gasket at 135,000 miles. They said I needed to buy a used motor for only $5,000 installed! They said the head gasket can’t be replaced, the head can’t be machined, and that a lot of 2010s have this issue. Attempted robbery! I had many other shops say they can do the head gasket replacement and recondition the head, so I did that for about 1/5 of the price and the Prius runs flawlessly. I am so glad I don’t have a used motor with a head gasket on it! Seiko you embarrassed yourself and I will tell everyone to avoid your shop. You should be ashamed.
