They are not BBB accredited! They do not abide by their warranties/ contracts! They are sketchy! I was recommended to P&G from sals auto mechanic in fontana, I have a toyota celica Gt 01 that had sucked up water into the intake. I needed a new engine. Sal had told me that this was the place to go. Alex, the owner had quoted me a fair price to install a new 1zz motor (the same kind my car comes with originally) he also said he could switch the position of my intake so that it wouldn't suck up water again.(He didn't) The job was to take 7 days and cost me $2200 with a 1 year or 12,000 mile warranty on all parts and labor. However, upon initial payment of $1100 and 12 days later. I called Alex and he said I needed a new air control valve because the car wouldn't idle right, he also said he needed to install a new "knock sensor", something I've never heard of before. It would cost me an additional $250 and another day of work, I said okay. I just wanted my car fixed. Finally after about 12 days and after I paid the $1450 I got my car back, I understand that cars with new engines have a "break in" period of 3 or 4 months for it be in top condition; so I made sure to drive with caution and made sure not to accelerate over 3000 rpms in between gears. After 1 month, my check engine light came on and my temp was spiking. I took it back to Alex and he said I needed a new temp coolant sensor. I paid $125 for the part and he installed the part. The problem did not go away. Not even a day later the light came back on and he said it was suppose to be a different sensor. He told me he charge me for this new mystery sensor, but after he installed it the problem seemed to be gone. I drove my car for 2 months before I got an oil leak. I took it back and Alex told me it would cost $600 for a new head gasket and seals, he also said that he would not cover it under the warranty because it was because of overheating due to the temperature coolant sensor, the same one that he installed 2 months before! Be warned! This company is not BBB accredited! They are sketchy! And they do not abide by their warranties/ contracts!

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
