My jeep kept over heating, I took it here after reading reviews and couldn't be happier! Honest and fair price.

These guys are just great! Time after time they have shown they are honest, capable and have integrity. Our most recent experience with them was for our 2016 Honda Civic, which had an A/C issue. This took several tries to figure out what was wrong as it wasn't clear cut. Once it was determined it was the condenser, Ron got the part quickly and we got our car back within a day (at 1/2 the price we would have paid the Honda dealer). We really appreciate the whole crew at Castner's! read more

It is hard to find a shop that will not rip you off and does a good job. Complete satisfaction over the years.

Castner's fixed my car within a day of it breaking down, and charged me less than what they originally had quoted me. Along with a coupon for future visits, Castner's included an oil change in my service and were sure to not overcharge for their services. Great quality work by quality employees. read more

Very honest shop I bring my car in my daughters car here and never worry about them trying to charge more than needed highly recommend

Awesome, honest repair business. I had my 2002 4Runner towed there for a second opinion on a break master cylinder issue. They did a full diagnostic and gave us an honest opinion about the cost and future of this 234,000 mile vehicle. No sales pitch or "you should do this" approach. My wife handled the whole thing and they gave her full respect as a women. Katie, in the office, and Ron, the owner, are a delight to work with. We are definitely taking our vehicles here for the foreseeable future. read more

I have heard about Castners Auto Service from friends around town for sometime now. I can't believe I haven't taken my vehicles there until now. My first impressions was a clean shop, friendly and professional staff and honest and trustworthy...basically everything I've been told by others over the years. I will definitely be returning as needed and recommending this business to family and friends. read more

It is so hard to find a trustworthy and decent mechanic that is also affordable and I have to say that this place is all of them. I needed a terminal replaced for my battery and we had called three other places that said they would not do it. My boyfriend took my car in without an appointment and they saw him right away and had my car good as new in no time. They were friendly and price was good I will definitely be bringing my car and our other car back here for service in the future! read more

I am always happy with the service at Castners. I know they are honest, friendly, efficient, and effective! Thank you!!

Wow...no one has reviewed this awesome, family owned and operated car repair service? Hard to believe. They tell you the truth, stand behind their work, and fix your car on time. They don't bring you in and start the up sell. They want you as a customer for life. I typically shy away from these type of commitments, but you have to have 3 things in life nearby where you live: 1) a reliable car repair shop, 2) a good, inexpensive italian restaurant, 3) a sports bar with adequate tvs for Sunday football. read more

Awesome service! I called this morning and spoke to very nice lady on the phone to schedule an appointment for a tune-up and oil change. They told me to come in same day and took great care of me. Ron and team were also able to replace an engine mount along with some tire maintenance. I was quoted higher than what the actual total ended up being. I'm very pleased with the end results of my car and highly recommend going to Castners for auto repair. read more

They were honest and fair on pricing which is so hard to find these days. The work was done right the first time and I haven't had any further problems, I'm so happy I found Castners! My Jeep is a 1999 normal wear and tear and now I have a place I can go to and trust. I'll keep my old jeep forever now :o) read more

My family has been coming here for almost 30 years. Very honest and reliable... friendly and good service. They are certainly not the cheapest always, but very fair and they do quality work. They won't scam or upsell you on things you don't need. read more

Castners has been very helpful with diagnosing many difficult issues on one of our vehicles that would not pass smog. They gave valuable direction and our older truck passed. They also have serviced our newer vehicles many times. They are honest and reliable! read more

Castners was able to diagnose a rattle noise from underneath my car when two other garages could not. They determined it was my secondary catalytic converter. They were even able to drop me off and pick me up from my office, which is only a couple of miles away. Great experience and would highly recommend to others. read more

I took my car in because it was overheating. I figured it was going to be something expensive. Ron, the mechanic, says it probably just needs a little fluid. What mechanic has ever tried to save you money? It ends up being a little more extensive repair because of a leak but the whole team is honest and up front. They called to explain my options and did not try to up sell me on some nonsense. If you are looking for an honest, family owned mechanic, Castners is definitely worth a try. read more

Castner's Auto Care is simply the best!! I know that when I take my cars to them, I am going to get great service and my car is going to get fixed right!! I also know that what they are fixing needs to get fixed. Lee (Grumpy even though he is not really grumpy is the best guy you will ever know) Castner started this family owned business over 55 years ago and now his son Ron runs the shop is simply awesome!! I was quoted by another local repair shop over a thousand dollars to repair something on my van when Ron told me otherwise charging me $250.00. Like I said, they are honest, trustworthy and fixes what needs to be fixed! I highly recommend Castner's Auto Care to anyone without any hesitation!! read more

Great service..never feel I'm getting ripped off. They open the gates at night to put my car inside. I drive 30miles from Eastvale just to use them read more

Went back for smog check, A/C check, new battery, oil/lube, check brakes, tires and hoses. All went well. Very satisfied with the price of the work, yet again. And now the car is 25-years-old. Yes, some of us keep our cars that long as they are still running well! YELP Algorithms - no freebie/rebate; no connection to the owner or employees. If you fail to post my review, which is from MY personal experience - we will have a chat. read more

Best Auto Repair shop I have been to! They were more into helping me out then getting a quick buck. Will definitely be coming back for any car problems I have moving forward!! read more

Wonderful shop, efficient and affordable service. Great family staff. I was new to the area and they were accommodating and timely with a quick check-up and repair! Many thanks! read more

Imagine my surprise when I get home from work and I'm walking past my car when I hear a loud THUD. I go to investigate and realized my 2005 Honda Civic was all of a sudden missing the window that was just there moments ago. In all fairness, the window stopped working years ago, but the glass stayed in place - until this fateful day. I knew that I was finally going to have to pay to get it fixed. I taped the glass up overnight and decided to deal with it the next day (Thursday). I called Castner's on Thursday morning and told them the situation. They said I could drop the car off Friday morning before work and leave my keys in the dropbox and so that is what I did. I received a call in the early afternoon with a price estimate that seemed to be fair and decided to go through with the repair. However, Castner's also went above and beyond and investigated why my check engine light was on and also gave me some information surrounding that issue and a price quote for free. I had called around to several dealerships concerning the check engine light being on and NONE of them would even look at it without a $125+ estimate fee. Castner's called me around noon on Friday and let me know that my window was already fixed. I picked up my car after work without issue. It's been a few months now and my window is still working great. I will most certainly be coming back to Castner's for all of the issues that my car has - and they are endless :) read more

One of the worst auto repair available . Horrible customer service Mary castner the co owner is incredibly rude and did not help me what so ever in fact I felt like they don't care about there customers . There just out to get your money 60 years of ripping people off ...i recommend Autozone at least they don't treat you like trash. read more

Castners is the BEST. I grew up in the auto repair business and I know that this crew is the best you'll find. Ever since my dad retired his auto repair business, I needed to find a place with integrity and expertise. Castners is the place. Thank you for always being honest, ethical and understanding. read more

Castners cannot be beat! My family has been taking our cars here for years, and we have been provided with nothing but the best service. Their honesty is what sets them apart - they will tell you what needs to addressed now, and what can be addressed later. I really don't trust my car with anyone else, and often make the trip from other areas in Orange County to have it serviced - they're THAT good. read more

If you want an HONEST auto repair place then Castner's Auto Service is the one! I had another auto repair place tell me that my 3 year old transmission in my CTS needed to be replaced. I went to Ron Castner for a second opinion. He told me it was most likely my brakes that where causing a miscommunication with my wheel module because of the shaking when I applied the brakes and I needed to replace one gasket spark plug tube seals, spark plug & Ignition coil So instead of $5,000 to replace a perfectly good transmission. It only cost me $1,200 that included turning rotors replacing pads, and other brake stuff. AND then I still had a hard down shift when going downhill and applying my brakes. THIS IS THE BEST PART, I went back to Castner's and Ron said "your brakes still don't feel right, I stand behind my work" so he then replaced my rotors, pads, caliper.pad hardware reline front and rear brakes, and other stuff AT NO ADDITIONAL COST!!! YES CASTNER'S STANDS BEHIND THEIR WORK. I HIGHLY recommend them. read more

Unbelievably trustworthy and honest - my family has trusted their services for 20 years. I'm always happy with their services and even when I'm living in other parts of Southern California, I'll be sure to bring my car to these guys. read more

family owned business. no pulling punches. completely honest and hard working people. had my car in for a smog check and within minutes it was already being taken care of. read more

I showed up for a smog check on a busy day and they were all able to check my car right away. Friendly service with a reasonable price.

super rude, impatient, unhelpful. overall a waste of time as they didn't try to help me w anything. would not recommend to anyone!

I just came home from picking up my car from Castners. They have taken care of it for a long time. As I was writing out the check, I joked that my car was almost old enough to vote. It is! It is 17 years old, and Castners has been taking care of it most of those years. It occurred to me that I would have had to replace this car a long time ago, and be saddled with car payments if I didn't have a good, reasonably priced, and honest mechanic taking care of it! Thank you! To Ron, and the good folks at Castners! read more

Top notch! My family has been going to Castners for years and years. They never try to upsell you and are always honest and helpful. I really would never go anywhere else. read more

You know how frustrating it is when your car breaks down, I called Castners, frustrated because I couldn't get to where I needed to be, and Katie answer and was so helpful, and that service continued the whole way through, they were fast, fair, and did great work, highly recommend Castners Auto Service read more

My husband and I took our car because I'd heard recommendations from others. We parked in the street. They refused to work on my car for a couple reasons that I consider ridiculous. He asked how many other cars are in my family. Strange but I answered. The others are under warranty so the work is done by the dealer(thank the lord for dealers that take care of your car and don't charge for the service). He said he preferred to work on the entire families cars. Then he didn't want to repair my old car. He didn't ever ask what was wrong with it, he never even saw the car. I thought it very strange that a qualified mechanic wouldn't work on a Chevy V-8 that is one of the most prevalent engines in the country. Never asked what was wrong, didn't even look at the car and didn't want my business. read more

castners auto service is honest, and fair. they take great care of me. ron is the man!
