I called about a week ago in a panic when my truck didn’t start the first 3 times I turned the key.  It started on the 4th, but I’m so not used to this — even though (to put this in perspective) my truck is almost 12 years old AND has over 210k miles on it.  I called right away and he said he could fit me in.  I drove up to San Marcos from SD to have him check it out.  Turns out I did need a new starter — which he was able to find one that same afternoon, replace it and return my car to me.  Especially since I’m so pregnant, it was even that more important to me to have a car that will start when I need it to and not leave me stranded waiting for a tow.  I trust Platinum Auto & Smog Service to keep me (and baby to be) safe on the road!

The owner, Hoa Nguyen, is a joy to deal with. He is friendly, knowledgable and explains everything every step of the way. I wish all my automobile repair experiences were this good. The price was fair, the service great, the communication better! I recommend them highly for all your car repair needs, not just smog issues.

If I could give this business SIX STARS, I would!

I went in to get my car smogged after getting the catalytic converter replaced. When I mentioned it to Mr. Nguyen, he said the catalytic converter might not be reset yet. He checked. Sure enough, not ready yet. I drive, drive, drive…. Come back again. Mr. Nguyen totally remembers me. He checks again. Catalytic converter not ready yet. Ok. He says to take it back to the place that did it to see what happened.

I have a hybrid so after my other mechanic checked, I had to drive the car a certain way to help the cat reset. FINALLY, third time I go back to Mr. Nguyen. I PASSED!!

This guy is great.  Master mechanic at a reasonable price.  Honest and does impeccable work.  Everyone in my family uses him and will continue to.

I have been a customer at Platinum Auto for 8 years…whenever there is a problem with your car you can trust that this place will tell you exactly what the problem is and not give you the run around…I have a 1997 Mustang and it has never run better 🙂 all thanks to Hoa and his team

Just had a quick smog check done by Hoa and his team.  Work was done quickly, and my car was ready sooner than promised.  He’s a very nice man, and was kind to my kids.  I recommend without reservation.

I came to Platinum by chance a year ago for a smog check and was just pleased with the expertise shown by the staff and owner.I have had horrible experiences with dealers and other shops in the area so when my wife’s car started to make a noise in the rear I remembered the honest guys at Platinum.
The car needed a wheel bearing and some coolant hoses replaced.
We had the car back within two days (in Sat- out Mon evening),great price,great service.I am never going near a dealer again,even if I have a warranty.
Thanks Platinum.

I’ve been going here over 2 years for maintenance and repairs for my 10 year old Camry and 4 year old Prius and I could not be more pleased.  As a woman it is difficult to find an auto shop that is not patronizing and trust worthy.  The owner here is very honest and respectful to me.  On top of that his prices are affordable and he does not try to upsell or get you to get services you don’t need.  I’ve referred several friends to this place and they all thank me for it.  An honest and reliable auto repair shop is a rarity and this place is a gem!
