Monrovia Auto Repair

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.

Only place I’ll take my Subaru for maintenance and repair. They’re very honest and you can eat off their floor. Everything in the shop is labeled and in order. The work is top tier and haven’t had an issue. Seiko is truly the real deal. They don’t play around when it comes to service and quality.

I needed to bring in a vehicle I recently purchased for a full inspection. I called 4 other shops in the area and all of them were either rude or too busy to have a normal conversation with me. When I called Seiko's, however, I was assisted by Sergio who took the time to explain everything their inspection would cover, in great detail. They were busy and didn't want to squeeze me in for an appointment if that meant they couldn't take their time and do the best possible job. I appreciate that kind of honesty. We scheduled an proper appointment and he laid out all items in order of importance, and went over preventative maintenance items as well. Very kind and knowledgeable team who took their time to make sure the work was done right. Their inspection came back in a beautiful webpage with amazing User Interface that shows a complete breakdown with plenty of pictures, making it extremely easy to follow along. Great communication -- Sergio checked in with me several times with updates on progress. Would definitely recommend this shop for someone who is looking for an honest and patient crew. Will be returning to this shop for future maintenance!

Great service and punctual completion. 1st class quality

Professional and detailed.

Extremely detailed approach to servicing my car. I walk away knowing what needs to be fixed and they give me estimates and photos of all the work that is recommended. I will always want to come back because Seiko and his team there make me feel important. 5 star service every time!

Experts who take the time to explain what each item means. Excellent service.

We've used Seiko's for several years for our 2008 Toyota Highlander and recently for our new Subaru Crosstrek and have always been very pleased with their services and recommend others consider them for their autos.
