April 28, 2026 and I have been stopping every month or so for 6+ months to have an OBDII scanner read the progress of my 2011 GMC 2500HD Duramax (diesel) resetting/updating so that it can pass a smog check. It failed elsewhere 6+ months ago. In the last 1 year and 3 days I have spent more than $5777 at the dealer because of DEF (diesel exhaust fluid) quality errors and fixes... Why the dealership? Because of the 2 year warranty. The DEF smog equipment is a sore subject that is NOT related to this business. At Premium Auto Repair Center, once I explained what I was going through and showing over 1/4" of invoices, they gladly took the time to check the OBD and share the results with me each time I stopped in/by. A shout out to the owner and all employees for your assistance and today it passed the smog check. As a side note, to avoid high emission output the ECU/ECM limits the truck to 55 mph and then limits the truck to 4 mph (so it can be loaded on a flatbed tow truck)... This state is a joke! read more

Owner personally consults and works on your car Has the attitude small jobs deserve the same thorough care as big jobs and he will tell you so! The place is immaculate for an auto repair shop devoid of Tit pics in The bathroom! The guy goes the extra mile to look for things that you would want to know about for preventive maintenance. I absolutely will go back and I fully recommend this shop! Thanks guys! read more

Naj and Premium Auto Repair is my go-to shop. I've been a customer for about 2 years and highly recommend them for great quality at a great value for the area. read more

Over long weekend my Magnum all of a sudden just wouldn't start. I had my suspicions as to the issue (fuel pump). Spoke to Naj and he told me to tow it to his shop in Campbell and he would tackle the problem first thing Tues morning. Car was done by 1 p.m. with a new fuel pump and a 2-year warranty. This was a great experience and I will be coming back Premium Auto. read more

Great service from Naji and his team. The whole process took less than 2 hours and I am happy with the result. Highly recommended! read more

I have been a customer for a long time and I appreciate the quality, honesty, as well as pricing at Premium Auto Repair. In particular I appreciate the courtesy and the fact that I never have to wait a long time for simple things like an oil change or tire rotation. Not only that, Naj the owner at one point personally came out to help me out when my car broke down on the freeway. Can you imagine that? These people are just great! I highly recommend them. read more

We came here for a nail. We specifically asked for a patch for the tire and not the gel plug. Guess what? They put in the plug !!!! I was shocked and disappointed because Naj was nice and explained the details. But the integrity was not here at this shop. read more

Warning: Untrustworthy Business Practices & Confirmed Scammer Beware of Mr. Naj's scam. I had a horrific experience with Premium Auto Repair Center and Mr Naj Jamali. Despite agreeing to use original or OEM parts, he installed aftermarket parts without my permission and charged me for OEM parts. Mr Naj promised a FULL REFUND if all the parts were returned, but REFUSED to honor this agreement, after all parts were returned. To make matters worse, I had to take him to small claims court to recover my money and WE WON. He appealed to Superior Court, but WE WON AGAIN. All this time Mr. Naj is holding on to my money and the aftermarket parts ( from SEPT 13 2023 till present ) Verified Court Records: * Small Claim Court Judgment Date: May 9th 2024 ( APPEALED ) * Superior Court Judgment Date : November 12th, 2024 * Court Records Available for public Review Protect yourself: * Verify parts used before payment * Insist on written agreements ( avoid phone agreements) * Avoid payment over the phone Do not trust : * Mr Naj * Premium Auto Repair Center Do not go to this shop, if you are scammed by him it will take you years to get your money back. Since October of 2023 I am still waiting for him to honor the courts order for him to pay us. Rating : 1/5 read more

Great shop. For me, it's walking distance and convenient to have my car towed there. I have had two things go wrong with my old GMC Yukon; battery drain issue and fan for a/c issue. Naj was efficient and speedy. Thank you Naj. read more

I believe that I can't find better service for my car. It's really quickly, with reasonable price and helpful and nice stuff. You should have to try to work with these guys. read more

My car was needed help. Two back wheels need replace broken pads. Guys made very qualified and fast repair. I appreciate their help. Thank you so much. I recommend this Auto Center. read more

Naj is a top notch guy. He and his crew are professional and trustworthy. I've used Premium Auto a couple times in the past with great value and service. Today he looked at my kids car which has some serious issues. The car will need to be sold to salvage but Naj didn't charge me a dime for his time to diagnose the issues. Anytime I need a mechanic I will see Raj and team over at Premium Auto Repair! read more

I came from Sacramento to see my kid in Campbell after I realize my car is shaking and check engine light on. I called premium auto. They told me bring your car and leave it for one hour. I will check it for you , after one hour. Naj called me and he told me number four ignition coil wire damage , I told him go ahead Fix it , Do whatever you need. I have to go back home. One hour later he called me. He said the car is ready , when I go there to pay and he charged me only $50 with the rainy day. I can't believe that. I recommend you guys go in the shop you would like it , and he's awesome read more

The best mechanic ive ever been to. ive had mechanics in the past who were rude, too busy to talk, and they do the bare minimum. Naj is the exact opposite. His work and his customer service is exemplary, calling me frequently as he went through the troubleshooting process on my 2003 Nissan Altima, which had a slew of problems. He went through the entire car and made sure the whole thing was in perfect working order, in a timely manner as well. No matter how busy he was, he had no problem sitting down and talking to me. Naj is incredibly passionate about what he does and it shows. read more

Outstanding! Naj is the man! He helped me resolve some brake problems with my Honda Odyssey. A few weeks went by and I thought I was having an issue again. Naj, at no additional cost, thoroughly checked my braking system and put my mind at ease. He even drove me around to test the brakes, which was very reassuring. I can't recommend Naj at Premium Auto Repair enough. Straight shooter who tells it like it is, and will not try to upsell you. I look forward to taking our cars to Naj for service in the future. read more

I brought my car in for Check Engine light. They said it would cost $650 - $700 to repair several things. When I picked it up it was $900 dollars. A few days later, I was driving it home at night from the hospital, when my car died. We got a tow truck to tow it to Premium Auto. The next morning I went there and was told by Naj that the transmission was shot. According to Naj, it would cost $5,500 to fix. The car's Blue Book was valued at $5,800. He told us he would call up his friend at the auto wrecker who would pay $2,000 for it less a $200 fee for whatever. 3 days later it was on his lot for sale!?! He tried to keep our personalized license plates, but my wife called and demanded he return them, which he did when she went and confronted him. He told the DMV that our license plates were STOLEN, so we were unable to attach them to our new vehicle. This guy is a scam artist - DON'T GO ANYWHERE NEAR THIS BUSINESS!!!!! read more

smog check and oil change done here they are so quick and kind and explained in detail

I brought my 2004 Isuzu Rodeo to Naj (owner) for repair assessment. Indeed, the noise on the front wheels when driving are coming from the worn-out wheel bearings which he replaced including the whole bearing assembly. These are my comments: - Naj is very honest, professional and easy to work with - His cost is very competitive - The shop is very organized and accessible - He has full crew of mechanics - Very timely - He showed me the old parts that he replaced - I noticed that he has many customers that are very confident with him about his work - Naj and his mechanics are very respectful and friendly There are a lot of mechanics I know and I brought my Rodeo to several of them before bringing it to Naj, and although they are all competitive in cost, I feel more comfortable and confident with him. And he definitely delivered a great result and customer service! read more

After Naj saw my original review, he reached out to me by calling me (many times) and texting me to try and "make things right". He wanted to "give me my money back" because he felt bad having my money if I wasn't satisfied with the services that his shop did. When I made time to talk to him and took him up on his offer, he back pedaled and asked how much I had paid (it was $1065 or so) and said he can give me $500 and asked if I would consider editing my Yelp review. Naj asked me to give him my credit card number. I wasn't going to give my credit number again, so he offered to write a check and said I could come pick it up. I did not want any more interaction with this buisness, and I figured he may try to talk me into letting him work on my car again, so I asked if he could mail it instead. I gave him an address (my work) and Naj kept texting me to see if I got the check yet, and he was asking me about the address. I finally texted him saying: "That check has not arrived yet. The address I gave you is my work. It will probably come next week. I will edit the Yelp review as you requested. Please stop calling me. At this point it is almost harassment and I will block your number." Its been 5 weeks since he mailed the check. The check has not arrive yet. I spent $3000 on my car (about how much it is worth) having another shop look at it and try to fix a jerking that the car started doing, after it left Premium Auto, when it is under load. The other shop just told me that the valve cover gasket looks like it needs to be replaced because oil leaked into the spark plugs. Naj's shop had replaced the value cover gasket (which I have done myself before, but I did not have the time and I've never messed up my car doing it). read more

See all

Called Naj to tell him about sounds my car is making- all he cared about was telling me about the review I left. I told him all i wanted was for him to check my car since he did the work and he said "I DON'T CARE WHAT HAPPENS TO YOUR CAR!" - i am so upset, all i want is for him to check the work he did, shouldn't there be a warranty on parts replaced??? I just want him to make sure the parts he replaced isnt causing the issues im having but he still refuses to look at it and tells ne to go somewhere else!!!' I cannot believe this! STAY AWAY FROM THIS BUSINESS. If you question anything he'll scream at you and tell you he doesn't care. Going to a new mechanic. read more

Service request, quality and value of work are always top notch and customer service along with excellent quality of work for auto repairs. I have taken two Lexuses and my Mercedes there to be serviced. I'm very happy with the quality of work performed. read more

I don't like leaving reviews but felt others should be aware. I came to premium auto center for a smog check after calling Naj the day before and confirming his price from the other reviews which was $50 total for a new car including the smog cert. Turns out that price is just to get you in the door and once the work has been completed they run up the tab to $90 for a SMOG CHECK because they can't "guarantee" pricing day to day. Very disappointing as Naj seemed like a trustworthy guy and got the work done quickly. However, be careful as charges tend to magically appear here. read more

I took my Subaru Forester in because it was shaking at high speeds and my dad and I had trouble figuring out the problem. I reached out to the shop and was able to show up same day at my convivence. Naj did a free diagnosis, he listened to the problems I already eliminated, and within 15 minutes he found the right control arm was broken! Naj was helpful in showing me how it was broken. Less than two hours later he replaces the part and test drove it to make sure the shaking had stopped. He even gave me back the broken part to show my dad. I really appreciate the free diagnosis as other shops and the dealership were charging $120-180 an hour for that service. read more

Was driving to another tire shop and saw this on the way so I dropped by and they were helpful and fast. I would come back again to get my tires worked on. A++++++ read more

This place is amazing to BS or nothing . Took care of what I needed . They answered all my questions and were very professional . Fast service too . I plan on coming back for future services . read more

I recommended this shop. Raj is professional and seems very trustworthy. He takes the time to explain everything in detail and show me the bad parts, and why certain parts are good and some are not. Prices are fair and much better than the last few shops I took my car too. The school district I work for uses Premium Auto for repairs as well. I have taken two cars here, my Tahoe twice and girlfriends car once, and have left in good confidence each time. read more

Naj is awesome. I cannot say enough nice things about him. I bring him little small projects and he treats me great. I know how much fixes cost and he's honest, very fair on his pricing!!!! read more

Couldn't help not giving this shop a review. Premium Auto Repair center has excellent service, they're not just friendly but they also have reasonable prices. I stop here for brake service and decided to also make a tune up for my car. I'll definitely coming back here for my next car service. read more

Owner overcharges / misleads female customers. I took my car here for an oil change and had no issues. Recommended it to my girlfriend when she needed an oil change. Naj did several unrequested work items on her car, including replacing air filters which she had just installed a month prior. Her final bill was several hundred dollars when the only work item she had agreed to was an oil change. read more

Strongly recommended! Naj is professional and operates a trustworthy business; he takes the time to explain everything in full, sells nothing that isn't necessary, and does it at fair prices and on schedule. read more

I went for a smog test. They were quick and pleasant to deal with.

I needed a tune up, oil change and brakes. I put out a request to 5 shops and Raj called me back first. Said he could check the car out right away and give me a quote. Shop is about 1000 ft from my house so I drove over. He checked it out and I could validate his suggestions because I do know about cars just don't have the tools and the time. Went inside spoke to him about what was going to get done and what is suggested to get done at X amount of miles and I agreed. He went further in explaining he only uses Denso parts for Toyotas which is Toyotas OEM factory parts pretty much. I was aware and impressed. He gave me a reasonable quote I agreed to drop the car off the next day. Dropped it off in the morning they just finished this afternoon and when I picked it up the price was significantly lower than what was one the original quote. He said it was just an estimate and gave me a kind nod and said thank you and have a nice day but didn't say I'll see you soon!!! Lol! Thanks Raj and fam! read more

I took my car in because it sounded louder than it has in the past. I ended up paying over $700 and Naj said it was only my engine vibrating and there was nothing he could do. For no other reason, except to get my money, he said i needed an oil and filter change and my rear brake pads needed replacing. I had recently had my oil changed and the sticker on the windshield showed i had only driven 769 miles. Regrettable, I did agree to this over the phone and he said the total cost would be around $600. But looking at my receipt closely after I picked up my car, he charged me $242 in labor to change my oil, air and cabin filters, flush my brakes, flush my coolant and install new windshield wipers. ( I did ask for new windshield wipers, but i swear they are working bad just like the old ones) Total cost $738.74. Brake pads plus labor totaled $278.25, and seems reasonable, but the other work wasn't necessary and i would not have agreed to if I knew the amount he would charge for labor. I WOULD NOT RECOMMEND USING THIS MECHANIC read more

As a retiree who travels frequently, it is important for my older cars to make the trips. From my first experience, Naj actually noted a disturbing problem with one of my vehicles. Fortunately, I followed my instincts and immediately drove into his shop before going home. I appreciated that he "showed" me the problem, which was disturbing and dangerous! The repair was done in a timely manner and has been running nicely. Ever since that day, I continue to take my cars to Naj. Couldn't ask for any better service. Thank you Naj! read more

Here today to pick up my SUV. It had a leak , which turned out to be a not so good job from an oil change elsewhere .. Naj helped out , always professional and reasonable .. read more

I attest the best deal quality work around. I did my searching and found him for suspension work. Genuine guy!

I have been bringing my blue 2012 ram truck there for brake service and he takes care every time - additionally, I've met a lot of mechanics, this one is honest. read more

Was driving and realized my turn signal was out on my car. Stopped by to see if they could replace the bulb and was helped immediately. They clearly new the car and process despite it being a '98 model. They took care to remove the taillight while taking extra precaution to protect the exterior paint, all right in front of me. 10 minutes later and I was on my way. Great service. read more

One of the best experiences I've had at a auto repair shop. I came in for a oil change, they topped off all my fluids. Shop was very clean. And they even inspected my whole car, No charge!!! Definitely recommend this place if you want a great service for your car!! read more
