Diaz auto Mechanic

Took my lady's car in (2019 Toyota Camry). Had a problem with the Coolant bypass valve (a common issue with these models) and Jesse (the owner) diagnosed it immediately. Even showed me a place to get the parts at the best value and did the repair in UNDER 1 hr!! Fast, effective, and a FRACTION of the price that any auto dealer would've charged me. Seriously saved so much money and time, and his expertise with vehicles made me certain that I'll never be going to any other shop in Moreno Valley ever again. Trust me, this place is your place. Nothing like it.

On January 23rd, I am visiting from Las Vegas to LA for business. On my way to a meeting on the 24th, I am staying overnight in a city called Moreno Valley. I got a battery sign on my way to the hotel after eating the enemy. For your information, I'm own a lot of vehicles because I run a travel agency. So I also have a little knowledge about vehicles. I found out at once that the problem this time was the generator alternator problem. But it was evening time, so I decided to just stay at the hotel for the night. Then, I searched for a nearby Meckenic shop. Then, I found a 5-star Meckenic near the hotel. It was the Diaz Auto Mechanic shop. After I got the information that it opens at 8 a.m., I arrived at around 7:50 a.m. the next day and was waiting for it. And the boss arrived at 8 a.m. ex

Perfect place , found a super dangerous ball joint tear that both 2 different (separate) mechanics missed and could of potentially caused my entire car to lose control while driving ! Forever grateful to them for my safety photos of my bushings. My new automotive repair go to !!! 100 stars

This family owned mechanic center is the best I have ever encountered. Even as a woman they respect your service. They are honest, reliable, and loyal to their customers. I have been taking my 2005 Toyota Highlander here for two years. They report the history of any service for better detection in the future. After taking my car here it has been running a lot better. I recommend this place 100%! Best prices as well.

In November 2025 I took my 07 nissan 350z into this shop because I started have idle issues. The car would shutter as if it wanted to shut off. The car would still would idle within spec. They diagnosed it said let's start with a spark plug ,throttle body cleaning and throttle relearn. These services would cost over 700 dollars. I agree to the services. 2 weeks later I pick up my car to a undrivable surging idle. The car is reving up and down on its own. I pay for the services he provided, spark plug and throttle body cleaning. It cost me over 500 dollars. The mechanic said some one else was working on the car. I've owned the car for about three years and done nothing but oil changes and brakes. Took my car to so cal Z in Colton and the diagnosed it top to bottom and said your 1st problem
