Emissions testing service near Diamond Bar, CA

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.

very good job

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...

A Godsend. My car broke down in LA while I was on a trip from N. Cal.. One call to Ray, a complete stranger to me, and my anxieties were put to ease. He took my car in right away and fixed it as good as new. Even though he could have charged me anything and I would have paid it, the job was done for less than the original, very reasonable quote. Thank you so much Ray. Muchisimas gracias! Tim G. Brentwood, CA

Let me tell you about JCW Auto Repair. On 8/9/2024 I was traveling from Berkeley CA after visiting my son, daughter in law and toddler grandson back to my home in north coastal San Diego. I had my 5 month old Corgi puppy with me, (she was a champ the entire trip). I noticed during the grapevine approaching the LA National Forrest the engine seemed to be working hard. I saw freeway signs recommending drivers turn off their AC during the steep grades and incline and I did so. Google maps redirected me to go through Pasadena to SD vs LA as LA rush hour traffic was slammed on Friday. Travel slowed considerably and I noticed my temperature gauge starting to rise in the stop and go traffic. I turned off the AC again, it was 107 degrees outside. Across the freeway from me was a Subaru car dealership, but it was now 5:01 and I know the service dept would be closed. I took the very next exit as I could see it was an industrial area and there had to be something there. I pulled over in some shade to let the car temp gauge to cool down. I saw the car repair shops were all closed. I thought about calling AAA, but what could they do other than tow me? I called my brother in law in SD, he had me pop the hood and check the coolant which was almost empty. He directed me to drive a few miles just west of my location to an O'Reilly auto parts store and he would coach me how to add the coolant. I started to drive about a block and found JCW Auto repair with the bay doors still open. It was clear everyone was closing up but stayed to help me. Jed immediately went to work, I popped the hood, he could smell the radiator heat. Jed immediately noticed my radiator cap was broken. I explained I had taken my Subaru to the dealership two days prior to my road trip to have the oil changed, tires rotated and the fluids all checked. Jed said the service department should have caught this broken radiator cap. Two jugs of coolant. Jed tried to find a used radiator cap that would work, he finally took one off his own personal vehicle that fit my Subaru. Jed cautioned me to drive the rest of the way to SD at normal speeds with no AC. It was blazing hot out there. He even gave me a jug of water if the temp gauge started to rise again and explained do not open the cap until it cools down. Jed seemed genuinely concerned and worried but felt I should be able to make it to San Diego if I take it easy. I asked Jed how much I owed him and Jed told me to give him whatever I thought was right. I am a widow traveling alone, I am beyond grateful for Jed dropping what he was doing to take care of me and get me on my way. He had along day at work and was ready to go home. Jed really saved me and my little puppy. He saved me an expensive repair bill or even my car breaking down on the freeway. I shudder at the danger of that. My sons and my family are exceptionally grateful too. It should be noted when I got to San Clemente I turned the AC on and the temperature gauge never moved from the middle center line. It was so chilly in the cabin my fingers and feet were numb with cold air. I would definitely, most assuredly take my vehicles to JCW Auto repair for all my service needs and might even drive to Azusa from SD for such quality excellence in service. This is the America I grew up in, where there was honesty, integrity and high moral character among our car mechanic professionals, where a handshake was considered to have as much value associated with it as a man giving his word of honor. JCW is exceptional car service care. Jed and his crew are consummate professionals. Again my profound heartfelt thanks

Star Auto Service is amazing. They really do the job right and take care of their customers. From the shuttle service to calling and giving me updates, I really appreciate their attention to detail. They even gave me a loaner car -- a Mustang which is considerably cooler than the minivan I left for repair. I've had a problem with an automatic side door that wouldn't stay open. The dealer spent an entire day and insisted I'd have to replace the whole door. I brought it to Star Auto and they were able to fix it for a fraction of the cost. They sent me a diagnostic of the whole car with pictures identifying the problem. Excellent service and great repair. A+++++ Jodi B.

Brought my vehicle in to have it diagnosed because it didn't pass the smog test. In short, dropped my vehicle off at 9:30 am, he didn't have it ready for me until after 4 pm. Billed me over $100 for 1.2 hours of work. When I picked my vehicle up, the drivers side window was stuck half way down. Couldn't roll it all the way up or all the way down. When I asked the mechanic if he could take a look at he told me he couldn't look at it because he had "other" customers and I would have to either leave it or bring it back in the morning. Told him I needed my vehicle for work. That didn't matter to him. Ended up taking my vehicle to a friends who was able to remove the door panel and fix the problem in about 30 minutes. In summary, they had my vehicle for 7 hours for a diagnostics check that took a little over an hour, was charged over $100 for that diagnostic check and then wouldn't take 30 minutes of their precious time to take a look at a problem that happened while they had the vehicle.

Took my car there to have smogged today...they failed me and told me that I would have to pay $175.00 to have my vehicle repaired to get it to pass...I said no and went to another station where my car passed smog no problem.. Never again!!!
