Emissions testing service near Rancho Cucamonga, CA

I have always taken my vehicles to the dealers for service but this place came highly recommended and so I gave it a try. The service and price were great. The owner and office staff are friendly and very knowledgeable and the price savings when compared to the dealership is significant! Bonita P

This company doesn’t take responsibility for damage caused by negligence of their mechanics. After four tows back and forth to their shop and a fifth to the shop that actually fixed the problem they don’t want to pay for what it costs to fix what was damaged caused at their shop, instead just want to offer a refund. This is like if they didn’t fix your brakes properly and you crash, they would just offer a refund on the brake job and not the damage caused by their negligence. It cost $650 to repair what their mechanic messed up and they want to offer me a $380 refund. Be aware, this company takes no responsibility for their actions. Off to small claims I go...

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

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

The reason I go to Rays Auto service is simply because I trust they give the correct diagnosis and repair it correct. its hard to find a place that is not trying to make an extra buck and up sell you.

I was facing this problem last two months and repair this someone repair shop but no solution found. My friends suggest TL Motors and when i call him they give me a quick response as well as quick repair solution. thanks guys
