This shop worked on a car I purchased from so cal performance. I had the car a total of three days before having issues with overheating. The dealer had me take it back to Sergio's. I was first told it was the thermostat and could pick it up the next day. Next day by 3 no call so I called and they told me it was a head gasket and needed the car for three weeks. (At this point I've only owned it 3 days and they forgot to put fluids in the car when they had it... )fast forward to 2.5 weeks later I get a call from So Cal that the jeep was ready. I go pick it up. Bring it home and realized my full tank of gas is now at a quarter tank, they rode their children around in my car cuz under the seat was a kids homework notebook with pictures drawn in it and Some fly traps. There is sticky stuff all in the back from something being spilled. They took the roof off my jeep as well because they forget to screw in the roof knobs back. They rode around in the jeep an additional one thousand miles on my odometer!!! I kid u not!!! See pics below I wish I was making this stuff up. I have a dent on the back door gate and my tags were swapped out cuz the temporary paper had been moved as well as the paper plates on my jeep! This is one croooked shady place! I am beyond pissed and will be contacting an authority figure! read more

See all

A friend referred us to Sergio's and we are so grateful! He did a free inspection and even came in on the weekend to accommodate our schedule. His work is excellent and his prices are reasonable. We will definitely use Sergio's Auto Repair again. read more

My boyfriend and his family have been going here for years. He recommended I try them out for an oil change. Sergio's did not disappoint! I called them at about 10a on a Friday to see if they could squeeze my Toyota Highlander in. The man I spoke to on the phone said of course and asked if I could come by in 30 minutes. I did and was planning to drop it off for a few hours and Uber home, but they told me that the service would be completed within 30 minutes. Wow! The shop is in an industrial area and shares a tight parking area with a few other automotive businesses. It's not the best part of El Cajon and the shop is a little messy and cluttered, but the things that matter most are on point. Sergio's boasts wonderful and friendly customer service, hassle-free communication, great automotive work and and VALUE. Thank you so much guys! I will be back for all of my service and will refer everyone your way read more

Amazing experience I felt like I was being taken care of by family. If you need your care fixed Five recommendation.... Professional and prices are amazing. read more

3 years ago I purchased a used car that was really giving me trouble and I was starting to have buyer's remorse. Out of the blue I found Sergio's and they have been a true blessing with tremendously fair pricing and solid skills to keep my car moving. In addition to that more than once Sergio's has advised me my car didn't need any immediate service which is rare or impossible for most Auto Repair Shops. Do yourself a favor and check out Sergio's!!! read more

Sergio was extremely helpful in getting me a resolution. My opinion has been changed on this business

We have been coming to Sergios's for 25 years. Ramon has helped us so many times. I highly recommend Sergios to all my family and friends and Ramon has never failed us. The services and prices are great. We have always found Ramon to be a very honest man. read more

So helpful and fast. Needed a diagnostic and check up before I drive across country. They checked everything and were really honest and thorough. Any work you need go here. Great customer service and great work. Thank you! read more

I was told yesterday by the Dealership that my front brakes were shot and needed to be replaced immediately. They wanted to charge me nearly $300! After a lot of calling around I reached out to Sergio based on the great Yelp reviews and I am glad I did! He quoted me an out the door price significantly cheaper than the dealership and well below the other places I called. And get this, when it came time to pay, my charges were actually almost 10 bucks cheaper than the original quote! Does that ever happen?! Super happy with my brakes and glad to have found a shop that is trustworthy and reasonable! read more

I have been coming here since 2000, I feel bad for not reviewing sooner, I have always received excellent service with fair and reasonable pricing. I come here for all my needs for Automotive, whether a smog check or most recently, a timing belt replacement. Sergio has worked on all of my family's cars, and I wouldn't hesitate to recommend him. I have never been up-sold services I didn't need, I trust the work performed, thats why I go out of my way to have my car serviced driving from Valley Center to El Cajon. Most recently I was quoted a timing belt replacement: ~Local mechanic (Vics Garage) in Valley Center wanted $400 + ~Sergio's charged me $333 out the door price. Thanks Sergio! read more

I have been going to Sergio for over a year for various services and repairs. He has done and amazing job. Extremely professional, Sergio goes above and beyond to make sure his customers are happy. I have referred him to all of my friends. Highly recommend Sergio! read more

I only choose 1 star to start my review, but they deserve "0" stars..... the owner is NOT honest at all, he quoted me 1 price to get my AC refilled, and then a higher price when he was done.... Witjin the hour of driving my SUV it overheated and I was lucky to pull to the side before the steering wheel locked.... 3 people brought buckets of water to help me out and told me that their was foul play involved from the shop that I took it too because my AC hose was not attached, my oil was drained; I had just gotten an oil change last month! And oil was poured on top of the radiator to make it smoke more!.... the owner denied it, but that was to be expected.... What they did to my SUV damaged the head casket!!! Now I am without a car .... they honestly deserve to be closed, to be fined!!! I am reporting them to the BBB after this review!... DO NOT GO THERE! read more

Sergio was very helpful and went out of his way to help me out. In my 21 years of driving and going to mechanics, he's in a league of his own. To prove my point, the shop is nowhere near my house/totally different counties. read more

I don't recommend this place at all, they changed a lot of parts and did not fixed the problem My husband brought the car for, he charged my husband $1095 for the parts and labor then told my husband that the problem was on the shocks and he replace them that finally got my problem fixed but still charged him $240 more, I think they did a bad diagnostic since the beginning read more

I took one of my cars to Sergios Auto Repair for replacement of the rear brakes, after my current repair shop (I won't mention names, but they are local.) advised that I only had 10 percent life left on my rear brakes and they needed to be "turned" as well. When I arrived to Sergios, for my very first time, the owner, "Sergio", greeted me and welcomed me to his repair shop. After a prompt moving of my vehicle (05 Chevy Malibu) on to the lift, they removed the rear wheels, and pointed out that I still had 90 percent life left on the brakes and they didn't even need to be turned! I was astonished that my "so-called mechanic", tried to burn me for 350.00 dollars!!! Sergio didn't charge me anything for diagnosing this issue, and assured me that my brakes were in great operating condition and had at least 2 years of life left, during "normal operating conditions." Sergio and his staff did an extensive overview of my vehicle and its mechanical needs. After the overview, Sergio pointed out that the coolant in the vehicle was very old , and I smelled it (had that "dead fish smell"). So he gave me a great deal and I had the coolant changed and serviced. He also pointed out that the brake fluid was quite old and could need a brake flush and add new brake fluid, he also gave me an awesome deal on that service too. I have lived in all parts of the states, and have never met such a professional, courteous, patient, and HONEST mechanic! Thanks again to the Team at Sergio's Auto Repair, C. Rocha read more

The absolute best mechanic in the whole wide world! Honest, fair and will NEVER price gouge!! Quality work!!! Call Ramon...he's the man!

Been coming here for a long time now ! I wouldn't trust my car with anybody else but these guys

These guys are awesome! I had gone to Firestone for my brakes and they wanted to charge me $450. I took it to Sergio's instead and he told me some of the parts didn't even need to be replaced and didn't charge ridiculous prices on the parts. He was quick and honest and easy to work with! I saved time and money going to Sergio's. I'm definitely going there next time I have car trouble. read more

Fantastic service! Sergio the owner himself took care of my car when I had multiple check engine numbers coming back. I had a P0303 code for a 2003 Ford Escape which multiple places were giving me a 600$+ estimates. He gave me advice where to get the parts at a great price and installed them all at the best rate I ever received. He even took me step by step what the problem was and how he fixed them. Just recently my check engine came back on, he told me to bring it in. The cord for my heater was burnt up and he replaced it in 10 mins no charge. This is a man who cares. He'll be getting my service from here on out. read more

My alternator went bad and the owner quoted me a fair price and was cheaper than most mechanic shops. I got my car towed to the location, and they repaired my vehicle. My alternator made some funky noises so the owner ordered a new one. Mainly, The owner was very polite and professional. My experience here was pleasant. Thanks. read more

Sergio worked on my car a few months ago and he was very reasonable. He asked me to come back if I was in the area again, so he could fix something that wasn't an asap thing, since I didn't have time to wait. Today I swung by and he cleaned my idle something (sorry don't know anything about cars) and put some new radiator fluid as a favor. I will definitely come back since service is great and reasonable cost. It's a little tough with parking sometimes in this location but Sergio is always out in the garage and will show you the best spot. read more

Horrid customer service, you should skip this place or you will be sorry. To top it off they don't know what they're doing. They totally lost my remote keys and then tried to charge me for having to get a locksmith to open my car again. Total scam artists. read more

You won't find better or more honest service. I have been going to Ramon for over 7 years, with all of my car problems. I can always trust him to do what's needed and no more. My wife took her car to Firestone in Santee, CA. Told that her brakes were weeping fluid and that she needed new rotors and calipers. I told her to get a second opinion from Ramon. His answer, no problem, everything in your breaking system looks great. Thanks Ramon read more

I would definitely recommend Sergio's! I had an amazing experience and I am so grateful that Sergio was able to take a look at my car FREE OF CHARGE! My car was overeating and Sergio and his team took a look and didn't even charge me. They were honest pleasant people and it was a pleasure doing business with them. Thank you Sergio!!!! read more

I took my car in to find out why the "check engine" light was on. After a quick diagnosis, the culprit was found. Sergio suggested that I take the car to the dealership to see if the part was under warranty. He could have easily done the repair himself and made some money, but he opted to save me some money instead. That gesture is greatly appreciated and I will, from now on go to him first. I doubt that you can find a more honest mechanic. read more

I been a loyal customer to Sergio Auto repair. i love their customer service! Very honest mechanics that are in the business to help you. Prices are very reasonable! I recommend their services to everyone. read more

Early November I stopped at the shop to inquire about services for my vehicle. A week later, after receiving an estimate and a diagnosis on what services my vehicle needed, I returned and left my vehicle for such repairs to be made. The original diagnosis consisted of a replacement of the "Speed Sensor" at a cost of $70.00 for parts, $70.00 for a certificate identifying my car's passing of the brakes and lights (ABS) requested by DMV, in addition to the $70.00 for labor. Later on the same day I returned for my car with all issues (it seemed) resolved. After driving the car for a few days I noticed a never before heard sound coming from the brake area of the vehicle. After notifying the shop and making them aware that this was obviously a result of the work done to the car, they agreed to inspect and fix the issue. After inspecting the vehicle I was told that it was no longer the Sensor but the car's computer which calibrates the brakes respond time which was not functioning properly, as such they decided it would be best to unplug the computer. After speaking to a second mechanic rep. at a different shop, I was advise that this procedure was quite dangerous and that the shop should fix the issue in a different manner. I took my vehicle back for what would be a third inspection, at this point I was given yet another diagnosis; the transmission. At this point I questioned both the previous diagnosis, as the ABS light turns on and off at different times of the day, and given the lack of the shops inability to provide a proper diagnosis, or to further investigate the work they had done on the vehicle. Both the owner (Sergio Tornell) and his son declined to provide additional work and rudely blamed the issue on my shopping car practices. My complaint is being made because as a female I feel that the multiple diagnosis and the treatment I received was due to my gender and to the perception that as a female I wouldn't know any better than to let it go and not worry about the $250 I spend at this shop. SERGIO TORNELL lacks manners, ethics, and professionalism--STAY AWAY FROM THIS FRAUD OF A SHOP! YOUR MONEY IS BETTER SPEND ELSEWHERE!!! read more
