The team at Alonso's Auto Repair are the best at diagnosis as well as repair. They stand behind their work and the work is done when they say it will be done! Great place!!! read more

I've been taking my 2002 Toyota Tacoma to Alonso's for many years and, until recently, always had great service. Unfortunately, over the last couple of years, that has changed. About a year and a half ago, they recommended replacing part of my front suspension (I believe the struts). When I picked up my truck, it had a loud clunking noise over every bump. I took it back, and the owner rode with me, heard the noise, and had it corrected. After that, the clunking was gone. A short time later, I started hearing a metallic clanking from the left rear of the truck. When I looked underneath, I found a hammer lodged near the rear axle housing that had been left behind during the repair. I removed it and returned it to the shop. The employee simply thanked me--no apology or acknowledgment that leaving a tool on a customer's vehicle was unacceptable. Then, about two weeks ago, I brought my truck in for a routine oil change and tire rotation. About a week later, I noticed one of my rear wheel center caps was missing. Since the center cap is retained by the lug nuts, it doesn't simply fall off, I am sure they forgot to put it on when they rotated my tires. I called the shop, but they said they weren't aware of forgetting to put on my Toyota center cap, nor do they have one sitting around that may be mine. As a result, I'm shopping on eBay to replace it. Not good..!! I don't know what has changed, but the attention to detail at Alonso's isn't what it used to be. Unfortunately, they've lost my business. I can't recommend them anymore. If you do choose to use them, inspect your vehicle carefully before you leave. I should have done the same instead of driving off after a service and assuming I received the same quality service I'd experienced for so many years. read more

We have always taken our cars to Alonso's. They are honest and always give great service.

Had them replace a radiator hose. Got it done in a timely manner and man behind the counter was very well mannered

Alonso's has been my go to repair shop for 3 of my household automobiles. Receive up front estimates and work gets done in the time quoted. Friendly staff that answers all questions. Im appreciative of the service I received at Alonso's Auto Repair. read more

I took my Honda clarity there to get what I thought it needed, brakes and rotors, by the way I'm not a mechanic. I was also hearing a noise from the front driver side area. The guys at Alonzo's told me they would take a look at it and let me know. Couple hours later, I get a phone call from them telling me that my brakes and rotors which I thought needed to be changed out are just fine. Additionally, they did not hear any noise coming from the front of the car a dishonest shop could've easily charged me for the brakes and rotors. I came to pick up my car from Alonzo's and there was no charge at all. These guys are terrific! read more

The sign of a good company, at least to me, is what they do when things go wrong. Less than a year into my rotor and brake pad replacement, I started to have issues again, just outside of the warranty period. To my surprise, because there are hardly any good/honest companies out there these days, they took full accountability and redid the job for free. Great people, great service, and they stand behind their work. You guys have earned a customer for life! read more

DO NOT COME HERE!!!! Quoted me $1900 for a radiator swap, got it done for $600 out the door elsewhere.

DO NOT GO HERE. This place used to be my go to shop until I noticed I was getting quoted absurd prices for the services needed. Took my car in the other day for a coolant leak and needed one 12$ part changed out Had to pay 200$ for a diagnostic check then Got quoted $1494+ 490 for a temp gauge... 2.2k to replace a part is RIDICULOUS. Went to a nearby shop and paid 250. This place WILL TRY TO RIP YOU OFF. read more

Found Alonso's on Yelp and it was 100% as advertised. Alfred greeted me while helping the other customers. the camaraderie between him and the other customers was very familiar and jovial. When he got to me, he was patient, thorough and took his time to properly diagnose the state of our old Subi. Once I decided to get the work done, Alfred got me a ride. Now the car ride is so much smoother, other and the work was super professional. Strong recommendation for Alonso's Auto Repairs -- Alfred will take great care of you! read more

Alonso's Auto Repair - Waiting to be fixed - Auto Repair Near Me - Upland, California

This is where we take our cars. These guys are courteous and easy to work with. Can I get it cheaper elsewhere? Perhaps. But I get great service, a price that seems reasonable and that comfortable feeling that comes from feeling good about not getting ripped. Also they do this thing where they always under promise and over deliver when it comes to estimating. read more

This is the first time using Alonso's Auto Repair. I decided to go with them because of their excellent reviews and their polite and professional customer service upon my first phone call. I spoke with Navy first, who offered to call me back with a more accurate estimate on my repair. He promptly called back and gave me scheduling options due to needing to order a part. I explained to him that my car is still operational and I have a newborn and would prefer to keep my car as mu h as possible. After discussing options with my husband we decided to go through with this pricey repair, this was the best price offered to me with the best reviews and they were very professional. I now worked with Freddy. Freddy asked for a deposit to order the part so I could keep my car until they were ready. It was a big repair and they would need at least an entire working day . Parts arrived I dropped my car off after hours on Sunday night, which was so convenient for us, and they promptly started working on it on Monday. They discovered that there was a gasket missing and ordered it. I had my car repaired and finished by Tuesday and they charged me slightly less than the original estimate. I'm very happy with this auto repair shop and would highly recommend them. read more

Unfortunately, I'm back again! My warranty company doesn't want to fix the problem that's happening all six cylinders so I have to come back repetitively but these guys have always been honest and upfront about charges, etc. and they're very professional. I appreciate everything you guys do thank you. read more

Great service. Efficient. And a friendly staff. Keep up the good work Been taking my car here for a few years and never a bad experience. read more

Somewhat difficult to write this review... because my wife and I have been taking our vehicles to Alonso's for the last several years. However, I have taken note that over the last few occasions that everytime they seem to find an issue that would cost us an extra few hundred dollars. Took my car in today because the engine light came on. But I mentioned to them that my wife forgot to put the gas cap on properly and I had tightened it this morning. They recommended $600+ in repairs. I declined the service...and the check engine has already gone off (a few hours later) They also recommended I replace the engine air filter....for $191 $191...WTH I drove to O'Reilly's...bought one for $26. Took two minutes to replace on my own. Don't get scammed read more

Finally found a shop that is honest experienced, and profesional. Took my 2002 Chevy Avalanche Z71 4x4 for a problem that couldn't be fixed by other mechanics. Alonzo's shop did an amazing job. The truck is running great and the price was decent. Great friendly people thank you NAVY for your kindness, guidance and support and most of all your willingness to work with the prices. Definitely will recommend the shop to anybody and will be coming back again. Thank you Navy and team! Happy Holidays! read more

Been coming here to get my car fixed and oil change. They gave me a very reasonable deal and told me the situation regarding my car issues with pictures as well. It was a pleasure working with Navy as he is kind and considerate of my situation with my car. He also gave me really good advice on my car. Will be coming here again, thank you! read more

Service was good, speedy, and they took care of the issues my car had. I wish the diagnosing fee had gone towards the total price but it didn't, which was why I had wanted to go here (reviews mentioned that it would go towards the total cost but it wasn't the case). Other than that, all was done well. read more

Honest, does a good job, and local. Really straight forward with pricing and services. We do our engine and mechanical problems here for our Toyotas. read more

Very quick and efficient service. I got a full synthetic oil change and transmission flush for $208. They were able to accommodate my schedule and get me in same day. Immediately after driving out the lot I was able to feel the difference in my car, running with power and smooth. I will be bringing my other cars here for service moving forward. read more

I recently moved out here to the Inland Empire and was in need of finding a reliable mechanic. It can be daunting to find one that you trust or that won't gouge you, so it's always a bit of a gamble. What I really appreciated about Alonso's Auto Repair was their point of contact and how pleasant they were to speak with. I felt respected, listened to, and felt like I could describe the plethora of issues with my car to them with confidence. I came for some apparent alternator issues which they reassured me were not the issue, and I had them look at a nagging sensor and cylinder misfire issues that I've also had for a couple years. My dealer and mechanic back home either quoted me exorbitant prices or couldn't get the job done, but Alonso's Auto Repair managed to reassure me of what I suspected was going on. They did it for a very fair price, several hundred dollars cheaper than I had anticipated it costing, and they were very detailed on what was going on and also gave me a detailed run down of the issues when I asked. I know there are plenty of people like me who are weary of mechanics and worry that the services, quality, and price will be an issue, but with Alonso it was anything but. I've certainly found my new local mechanic, and as long as I'm out here, I'll be taking my car to Alonso's for any issues I have. I have no reason to not give them five stars, they absolutely deserve it. Thanks again for your help, and please thank the young man at the front desk for his clarity, customer service, and great attitude and demeanor. He made this entire experience so much easier, and is a huge reason why I'm giving a 5 star review and will continue coming back. read more

Took my truck in for transmission issues. The patched up a leak or two on it, but in the end, my transmission was shot and I have to go get a new transmission. In my opinion, it would have been professional to have explained to me, "look your gonna have to get a new transmission, do you really want to pay over $500 for a leak?" 3 days later, my transmission went out. These guys never explained the fact that they'd charge me over $500, when eventually I was going to have to go get a new transmission anyway. Just a typical, milk you for what they can mechanic. read more

Honest and trustworthy. The most friendly and polite staff I have ever met at a shop like this. Treated me like a Queen. Can't recommend Alonso's enough! read more

My car's battery died and had corroded over. With friends visiting from out of town and staying with me, I needed my vehicle back up and running as soon as possible. After calling a tow truck company, I called Alonso's Auto Repair to see if they had availability to service my vehicle once the tow truck company arrived and could drop my car off at their repair shop. The service manager on the phone was pleasant on the phone and in person. They got the repairs done before the estimated timeframe and my car was working again within a couple of hours of getting it dropped off. I would recommend this business for auto repairs and will be bringing my car back in the future for maintenance. read more

I've taken two cars here in the last several months. I needed the AC replaced on one car and a whole bunch of stuff worked on for another car. Here's what I have to say: Amazing service. Incredible work. Fair price. They made me feel very comfortable throughout the whole process. I could not recommend more! Alonso's Auto Repair is legit and I'll definitely be using them again. I feel lucky to have found such an honorable a trustworthy spot! read more

UPDATE: Worst part of the whole experience was the response below lol. Franky, judging from what you said it seems what was wrong with my vehicle was lost in translation as multiple things you've stated aren't quite the case. You can say "30 years of experience" as much as you'd like, but if your tech tells me my system is empty, and it's not, he's wrong. 100 years of experience couldn't change that, nor is any exstensive experience really required to objectively prove the info I was given was inaccurate, even if I understand how he reached that conclusion. Upon another inspection, the issue was the expansion valve. These systems can be complicated, yes, but simple maintainence is very doable by anyone who learns a little know-how. It is a disservice to DIYers, and the right we have to repair our own property to simple wave it off with "it's complicated". Good luck with your future business endeavours. read more

Alonso's Auto Repair provides professional, high quality auto repair. I recently had the radiator crack in my car. The professionals at Alonso's were able to get the parts and repair done in a timely manner. The mechanic also looked over the other hoses in the car to make sure all was in good repair. I valued their timely communication on what was happening and when the repair would be done. The value of their professionalism and skills at Alonzo's is invaluable. I highly recommend this shop. Great value. No hidden prices and final bill came in under the quoted price. The BEST! read more

Protect your Prius' catalytic converter! Alonso's installed a Miller Cat stainless shield on my Prime, they have them in stock too. No rattle, this is not a DIY job. Alonso's has helped me out with oil changes, major work and little rattles. Super fair pricing, honest and friendly business. read more

I got a Pre-Purchase Inspection at Alonso's without ever stepping foot in the shop. Lexus dealership charges $400+ for a full PPI and Alonso's did it for around $100! They were fast, professional, courteous and the best part was that they shared the full inspection results with me electronically! Navy helped me and was so great and helpful. Would highly recommend. read more

My husband and I have been going to Alonso's auto repair for a few years now. They do an excellent job on our cars and have the best prices! They are timely, kind, reliable and have integrity!

Great customer service and quality work. Always good prices and very trustworthy. I bring both my cars here every time I need service.

Hinest, hard working, no fuss, excellent service all around. Definitely would purchase my next vehicle from Raul. absolutely satisfied without any doubt Highly recommend thank you Joan v in Santa Barbara read more

I come and get oil changes which is ok the only bad experience I've had here is that I was told I needed new brake pads when I really did not. My sons uncle checked the pads only because I knew it couldn't be that I needed new ones I had just got them done not even a year ago I even took a pic of how thick my brake pads were and they wanted to charge me $210 to replace them. I wouldn't trust this place too much. Sorry. read more

5 stars for quick and friendly service, and great communication. I took my car in on Monday afternoon around 2 pm for an inspection because dashboard light kept on flickering when I drive. Vidil, the front desk technician (my apology if I spell your name wrong) was very helpful. The next day, they called me at 11 am to inform me about the issues: battery and alternator works fine, it was the battery connection. They found 3 more problems: rears shock suspension oil leak, air filter, and nonfunctional tail lights. Total $499 for everything. read more

Alonso's is amazing, they are incredibly professional and well organized. I've been coming here for the past three years since I attend college nearby. Being a college student with a tighter budget and some bad luck with my car, Alonso's has been great. I've had a couple serious issues come up with my car: they replaced some crucial wiring that had been damaged by a rat, and gave me a discount, they did some difficult work on my passenger airbag and sensor, and I bought new tires from them after one of my old tires blew out, at a discount considering the quality of the tires and the price of nearby tire stores. Just last week, I noticed my roof rack was broken, I took it in and they saw me immediately, they repaired part of it but we found that it was structurally broken and unfortunately could not be fixed. They also topped off my fluids, and did all this for free. Definitely come here if you're in the area! read more

Great customer service, trustworthy and doesn't overcharge. Will definitely be going back for future service.

Let's list all the positive experience I received from scheduling my appointment to when the keys were returned to me. 1. Appointments were avaialble and flexible. 2. Felt welcome and they listened to my additional concerns. Their customer service was exceptional. 3. Waited a decent time at the waiting area. 4. Vehicle was returned and everything I asked for was checked. Overall, my experience at this location was extremely positive. Keep up the positive work!! Would definitely come back. read more

Lots of honest people here. They don't try to rip you off or anything. Very knowledgeable technicians too.

My car's engine check temperature light turned back on after another shop was unable to find the cause a month ago. I took it here to Alonso's and they were professional and transparent about their process and prices. They made sure they were able to identify the issue and not only that, they were even able to provide additional recommendations about other concerns I didn't even bring up (ie a rattling noise coming from the vehicle). They reached out to me to decide which repairs to have completed and provided a quote/estimate beforehand so that nothing was charged without my consent. One downside is that they aren't the cheapest in the area but they are upfront about cost and get the work done. I was able to add on an oil change with no problem and they assured me the car would pass smog test as well at a STAR certified location (they're working on theirs). I appreciate their integrity, honesty, professionalism, skill and hard work, and recommend this shop to anyone in the area. They really know their craft. Additionally, they have an online portal to be able to review and keep track of the services done and notes on your vehicle- useful and impressive! read more
