My car made a grinding sound before bringing it here. They did a free inspection of my vehicle and proceeded to fix the problem for me free of charge since the problem wasn’t that bad. I highly recommend this auto shop. They are affordable, honest, and friendly people.

Went to LA to visit family and my car started rumbling. Took it in to Mendiola And they did a great and honest job. Turns out my rack and pinion had a bolt loose. I'm glad they didn't try to sell me a new one. Antonio and Arturo Sr. are very honest and professional. Definitely appreciated their work

It was after hours and my car ran into some trouble. Came across this guys. Not only did they rush to help me, but they ordered car parts last min. One guy got in his car to go pick up my car parts, while the others started working on my car. Got a great price on top of all that and they still made time to have a friendly conversation. I'm so grateful I came across those guys and I will go back for my future oil changes, because why? They use great motor oil and great prices, that's why! Thanks guys! I'll be back.

Arturo told me to sell my car or put in a new engine for 2600 dollars. A real steal of a deal. I asked him: can a tune up fix the problem? He said "no there is water in the engine and the engine needs to be replaced". I worked on the car myself and had Pep Boys in Pomona do a tune-up and voila I avoided giving this man $2600 dollars. If I had sold it and been a total NPC, I would have lost a lot of money. Don't trust this guy. What solidified my opinion of him was the work he performed on my secondary car. I took it to Arturo for an oil change and was returned it with leaks to which he said the gasket was messed up and he needed to order a new part straight from the dealer. It would take weeks. I took it to Gabriel's in Chino and they told me the leak was due to an oil pan that needed re-threading and a part that costs pennies. Arturo was not even busy on the Sunday when I took him the car yet he feigned interest in fixing it while wasting about 20 minutes of his and mine time looking at the car, seeking for an origin of the leak. I don't know if it is a skill or intelligence issue. I would avoid. He actually wasted his time and was not able to identify the leak. I was even willing to pay him for fixing the car but no. Under other circumstances, regarding the primary car, he could have been held liable for foregone use. He is truly lucky I am not an NPC.

They repaired the water pump and ac on my work truck. They did a fantastic job and was very professional and courteous. I highly recommend them for your repairs. I enjoyed their work so much that I took my wife’s nonprofit GMC 2500 to them for repairs. 👍🏾

These guys are amazing! Got the best price ever on oil change, also he noticed my coolant, power steering fluid, windshield cleaner tank were empty, he filled them up for free. Nice, honest people! I'll definitely go back again, even if I'm not from that area!

Arturo and his team has helped me greatly with my BMW with oil changes, brakes, radiator leak and right now my starter just to list a few. He is someone I can trust with any car troubles and is always reliable even after hours. I am so excited to see the journey paid off and him always be a strongly recommended mechanic that is truthful! I hope you get to experience the care and hard work they will provide for you and your vehicle! They are the absolute best and have great prices!!

I own a 22.5 high country 3.0L (lm2) silverado 4wd, found this family owned shop and they were great in servicing my truck. They removed and replaced my #2 glow plug for a great price. Met Arturo and Antonio who worked on my truck- great guys down to earth in helping me out. Pretty much found my "go-to" shop to take my truck to have services done..

It’s very nice to get to know MENDIOLA AUTO from a oil change place. They are not only skillful, knowledgeable and professional in most of brands vehicle but also very honestly and responsible as one of our friend. Arturo was accidentally charged my credit card twice more in the first time use new digital machine and don’t know how to refund. He said he will call bank to refund in the next day. He have responsibly texted the next day that money has been redounded by his bank before I call my credit card bank! What’s an honest and skillful person in here. 👍👍👍

These guys have never let me down! I've never felt cheated or lied to by them! I've come in thinking it was a major issues and they inspected and found out the cause was something so minor they didn't even charge me.

This is my top mechanic shop to go to. Mendiola diesel and auto has never failed me. I have gotten my transmission changed here, my air conditioning fixed, lights fixed, oil changed, anything that would go wrong with my car they have fixed. They have reasonable pricing and they are the friendliest people. I would highly recommend you to check this place out if something is wrong with your car.

Another mechanic wanted to charge me $3500 to fix my engine on my 2016 civic with 100k miles as it wasnt starting. Took it here a few days later to get a second opinion and all I had to do was pay $400 for a tune up and maintenence. Honest people
