very helpful and understanding of what my situation was. was able to work with me on price as well! I will definitely recommend this shop out to my Friends and family. read more

Came here the first time to get a belt replaced along with a change of oil and coolant. Came back for a brake and rotor replacement. Each time they gave me quality service from mechanical to customer. Will be returning for future maintenance/repairs because the workers are kind and hardworking and the owner of the business is just the same. No wonder, everyone else is the same easy because the owner expects quality. Definitely recommend! read more

Monroy's Auto Repair - Auto Repair Near Me - Fontana, California

DO NOT BUY A USED CAR FROM THIS MAN! HE IS DISHONEST AND DOES NOT LIVE UP TO HIS WORD! My family went to Monroy's for over 15 years and had no problems with their service until he sold us a car. He said that he had a 2009 Subaru Outback that was not working but he was going to get a brand new engine for it and would fix it all up, make it right, and sell us a great car for $7000.00. This thing was never working from the day I got it from him. It kept on breaking down in the middle of the road in the mountains after only a few days of using the vehicle. I say only a few days because I barely had the car in my possession a few days since it was always back at his shop being fixed for serious issues. I took it up to work and it over heated and would not start. I had to wait a few hours before I could drive it again and slowly got it home and then to his repair shop. He said that he fixed it, (It was never actually fixed) but that he would not work on it again without me paying for the bill. I told him he sold us a hooptie and would never go back to his shop again. We only had it for 4 month! Most of that time it was in the shop for weeks at a time. We only have driven the car for 2000 miles over the span of a year because of all the smog it spews out and fear that it will not start again. Well, today the car did the same thing to my wife as she was driving down to Ontario Mills where it stalled in the middle of the road. She was terrified. I had to drive down to give her my car and try to take the car back to my house not knowing what was going on with it. I couldn't make it back to my house without it oveheating and stalling out on the side of the road. This car was the most costly mistake of my life. We have put over $1000 trying to fix the car. It would not even pass the smog test a year after we bought it. Now it does not even work and is currently sitting on the side of the road with steam spewing from the engine bay. Very disapointed and very dissatisfied. Please don't buy a used car from this dishonest and unscrupulous auto mechanic. read more

Been coming to Monroy's for years, never have I had an issue or problem with their work, service, professionalism. They are truly honest and will not beat around the bush.

We've had basic maintenance done, oil changes, a/c work, fuel lines replaced, suspension work, brakes rotors etc...... it's truly been a problem free experience every single time. Thank you again for everything Jose & Luis . We really appreciate your work and honest ways. Definitely made a customer for life from us read more

Monroy's Auto Repair - Auto Repair Near Me - Fontana, California

My car was leaving coolant and I had originally been quoted for around $2000. I called Monroy's and right away was told a estimate that was $1000 cheaper. Not only was the price good but so was the service. The turnaround time for my service was less than 24 hours. So far my car has been running smoothly and I have no complaints. I would highly recommended and will be back for future services! read more

Took my car here and Jose was sure my car needed big work on the motor which he quoted 2,200. He Had the car for over two weeks not giving me updates throughout. A year later my car starts acting up and Jose said it had nothing to do with the job he did so I took it to two other mechanics. To my surprise both said almost the same thing, the person who worked on my car's motor (Jose at Monroys) did a bad job and now I needed a motor replacement. So I wasn't sure and took it to Chevy dealer which there I was confirmed the same thing. Due to bad job Jose did on my car I ended up paying another 7k for a new motor. Stay away from this place, Jose will take your money and mess up then say it's not his fault. It's what always happens when mechanics such as him do when a woman comes in hoping to get good honest work. They will take advantage. Ladies, just don't! read more

Check your vehicle with another mechanic after coming HERE ! They did so much to my truck that they shouldn't of according to a specialist. When truck was received oil stains were everywhere and screw were laying around my seats ! Not an HONEST SHOP ! read more

First of all, I have been a loyal customer for many years. I've known Jose Luis since they were located at Citrus Ave. Recently I took a Nissan Rogue that needed a front driver side replaced and they quoted me $450 and they said it would take 3 hours. So I decided to take the vehicle to another shop up the street and they charged me $175 and it took them less than an hour to replace it. I think I will be taking my business someplace else from now on. I can't even get a hold of the owner anymore. read more

This guys have been maintaining and fixing my cars for the past 6-7 years. I've never had a problem with them, if fact they always exceed my expectations. Reliable, thrust worthy and easy to deal with. They always do a good clean job. I highly recommend Monroy's Auto Repair! read more

ABSOLUTELY satisfied. I walked in and simply said my car is overheating and Jose dissected the car and got right to the problem which his neighboring competitors could not do.

I took my car in for the air conditioner, it just wasn't blowing out cold air. They quoted me over $1,000. I declined having them fix it because that price is way too high.

I can honestly say Monroy's Auto Repair is the best place to take you're car. I work for a dealership around the area and we've taken all our cars here! He's an honest humble guy that'll fix anything, he's been a mechanic for 15+ yrs and he'll tell you straight up whats wrong with you're car most mechanics will try and get an extra buck out of you but he's just here to make an honest living and I can appreciate that. read more

Honestly, I'm pretty disappointed with the work that they did for me. I was quoted a great price to get my back brakes and rotors replaced, so I decided to have them do the job. The customer service was okay and they did finish the work on time, at the price I was quoted. HOWEVER -- Shortly after I took my car home, I noticed an awful grinding sound when I would put on the brakes, coming from the back of the car. I didn't take it back to them, because I assumed it was something else. Why would brand new brakes and rotors be causing this horrible grinding noise? Well, I had my car looked at by someone else, and I was told that the upper caliper bolt was missing on the back right-hand side. So, I'm not saying they forgot to put it back on or didn't put it on properly... But this grinding noise started happening about 1-2 days after I got my car back from them. So, I'm kind of assuming someone here dropped the ball and did shoddy work. I won't be back here. read more

I had come here per a family member's recommendation because of the consistently great service they received. I decided to give them a try over my usual shop and was pleasantly surprised. Jose is so helpful and accommodating. They were able to squeeze us in on a weekend with no hesitation and answered all of my questions. Service was quick and painless-- I highly recommend! read more

This is a honest shop! after going to a couple shops to fix my car everybody recommend expensive and unnecessary fixes because they didn't know the root of the problem, the owner (Jose) found it in a couple minutes and after one hour the problem was fixed! i will definitely bring the family cars over here You can check all the services and coupons on their website http://monroyauto.com/ read more

I definitely recommend Monroy's Auto Repair!! 5/5stars!!

I was leaving out of town (I was actually moving) and going on a 7 hour car ride. I had just bought a new car a few days before and the day I leave the a/c decides to not work! I knew going to the dealership was going to take too long and I was on a schedule. I googled auto repair shops nearby and Monroy's had great reviews so I decided to go there. He was extremely helpful and was able to fix my a/c situation in less than 30 minutes. I would highly recommend anyone to take their car here. read more

My family and I drive from Pomona to Monroy's in Fontana because the mechanics here are excellent. Jose is always honest, he's reasonable and reliable. He knows his stuff. We always leave there satisfied. The latest work he did for us was on my daughter in law's Ford Explorer. The front suspension was replaced, rack and pinion, power steering pump, front and rear shocks, front and rear brakes, upper control arms, lower ball joints, rear drive shaft pinion seal and brand new tires. She was very happy when she picked up her truck. read more

I took my truck in for an oil change and transmission change i found excellent service i would definitely recommend

Every once in a while you encounter someone who is not only expert at their job but also extremely professional and personable. This was my experience with Jose at Monroy's Auto Repair. I called the day before regarding a pre-purchase auto inspection and he was very accomodating on the phone, explained everything I needed to know, and assured me he could do the inspection at my requested time the following day. When I arrived he was very friendly, accepted the vehicle and knowing I was on a short time frame with the vehicle told me to return in only one hour. When I came back he explained the entire inspection in detail, made a good estimate of necessary repairs, and even gave me advice on what price to offer on the car! Jose's knowledge is vast and he answered every one of my newbie questions in a very friendly manner. I left the garage feeling extremely confident and I highly recommend his services to anyone. read more
