Auto inspection service near Fontana, CA

Probably the most honest place in town. I came because Econo Lube told me I needed new brakes which sounded fishy since they were about a year old. Came here and after a few minutes they said I didn't need them. They just needed some tweaking and cleaning. Boom! Worked like new, no more terrible noise, they wouldn't even take my money. The whole team is super nice. We've been here tons of times, they might not always be the cheapest game in town but they've got a customer for life. Erick Uribe

This establishment offers great customer service on top of their excellent auto services. They go out of their way to make your day easier. Kelsey Freitas

Today 8/8/2015 I took my truck to SmogZone at 12365 it was about 3:45PM, they closed at 4:00PM. I was greeted by John Yang who speaks limited English. In short he ran a SMOG Test on my truck, he never brought it into the bay to run any RPM tests. At 4PM he tells me "Oh your truck didn't pass." On the form he points to Smoke Check. He said "I do not know what that is, you must go to a SMOG Certification to have it checked, I'll charge you $35 to retest in 30 days." I was so upset, the truck has 36,000 miles, not a hint of smoke. I came home and looked up Smoke Check and found he is the one who enters Smoke Check. I plan to dispute the $49.75 he charged me. I should have known based on their previous bad reviews not to go there.

this business is a giant scam. they live and feed off people failing smog tests for no real reason. hard working people come here to have their cars tested by an honest business and get shafted with bull crap excuses and misinformation. im angry cause my car failed smog twice and as business owners these guys should except people to be angry when hard earned money is being flushed down the toilet. the first time it failed was because my car battery had died and apparently the car cpu resets its monitor checks so even tho my car passed smog with flying colors since the computer hadnt done its own monitor checks they failed it. this second time i bought a code tester to see when all the monitors were ready to go which they were when i showed up. i thought all was gona go well until the young smog technician who cant explain his way out of a paper bag tells me my car failed due to a vacuum leak. having failed smog before i asked him did the car fail smog or did it fail because of a vacuum leak. thats when these weasels start to work their magic and all they see is a big fat $$$ on hard working peoples faces. he starts to tell me it failed because of the vacuum leak then he says theres a cracked vacuum hose if i wana take a look at it... he told me there was some tape on the hose and he removed it and saw there was a crack on the boot of the hose. i was angry he even removed the tape. i thought this was a visual inspection not a remove anything you see from my car and do what you want. he didnt even ask me if he could go into my engine and star removing things from it. granted it was just tape the state laws say VISUAL inspection. im not sure if these guys are thieves or if they participate in unlawful activity to make sure people dont pass smog. on what planet does visual inspection mean start pulling tape and componets from my car ? the owner walked in and hes just a big an idiot as his technician . using word manipulation and scare tactics to get people to pay for their crooked thieving practices. they make so much money from failing people its not even funny and they know this. just before my car was smogged a gentleman had also failed because he was not aware you had to drive your car an X amount of files to reset your car monitors or regardless if your car passes the actual smog portion of the test they will fail it.. these guys are very unprofessional and its obvious they live to rip people off. yes i was angry for my car failing but what made it worse was these guys obvious scam tactics and manipulation . visual does not mean start fooling around in my car removing things you should of asked me before you did. i will never go back again and i hope no one else does either. you have been warned.

ou. The owner Lary is a great guy and will work things out for every customer to totally understand what's happening to their vehicle . I trust this place and it's service and would definitely recommend this shop to my family and friends. =) -Kat Critchfield

I bought my Pontiac brand new in 1988. 277,000 miles later it's starting to have a few problems, especially with the fuel injection and passing smog. IS&R fixed its current issues in one day and charged far less than I had expected to pay. Good work done quickly for a fair price. Now I'm trying to decide which of its other problems to have them look at next. Craigs great to work with as well!!!

I was on vacation with my family and I had a tire that kept losing air. This place hooked me up with a new tire valve and got me back on the road in no time! I came in with 20 minutes until closing time and they still provided fantastic service! Great customer service. Highly recommend this place for any tire needs! -Kristie Phillips

Amazing work. The owner Kenni is an amazing woman. It makes me feel so comfortable taking my car somewhere to get an oil change especially being a woman because I know they will always be honest with me. I will always come here for any of my car needs.

As a lady needing my car smog I was treated with the upmost respect and they explained everything in detail so I could understand. Very hi honors to them THANK YOU! Deb

really nice guy! he knows his cars especially specific cars and what goes wrong. they were budget friendly, i will go back! 5 stars

Decided to give this repair shop a chance since it's close to my house. The facility was clean and the manager Jonathan was very courteous. Oil change was done in reasonable time and price was great since I was able to use coupon. Jonathan was patient enough to answer any dumb questions I had after the service. Great shop!

1 year ago my brother-in-law referred me to Midas Diamond Bar after I told him I felt the Toyota dealer I had been going for 3 years up-sold some unnecessary services to me. Since then this place has been my go-to shop for all my car maintenance and repair. The staff (Nitin) was really nice and very honest. Doesn't try to push some unnecessary services to you. They make sure that they take care of you nice and fairly and that you feel comfortable with them so you will come back. And I will def come back. -Jared Wu

Got a flat and got it towed here because it was close to Cal Poly. People here are really nice and they fixed my tire for free! Brian was really cool and we had a friendly conversation while Mynor was fixing my tire very quickly. Probably the best experience I had at a car service location. Highly recommend! Jose Jimenez

I'm tow truck driver and this is the only place I recommend to any of my members the employees are great and with that you get great service Tamara Garvey

Horrible just horrible! They insisted I make an appointment. I dropped the car off knowing what needed to be done on my car. Three hours later I call and ask what time it would be done. They say they were going to be calling, they hadn't done what I asked them to do. They had found more codes along with I already knew needed to be done. I end up having to pick the car up the next day because of their ridiculous prices to fix the new item they found. Paid $85 for them to not do the work I agreed upon, and for them to tell me other codes were popping up. Don't think about arguing with them, when I did they refused to take my debit card and made me go get cash in order to pick up my car. I would never recommend these people! They might be cheap to beginning with but definitely not in the end. They turned out to be a huge waste of my time and money!
