Great service. On Time. Fair prices. One small critique. I had to call to check on my car. They say they will call me back a few different times and didn t. I had to call back.

Great communication via multiple channels, love the visual aspect that your inspection pics provide to give an idea of the condition of the vehicle. Very transparent shop.

Brittney, Jonathan and the mechanics are great. Professionalism and a positive attitude does matter.

I got my car towed to CSAI auto by AAA as a AAA certified auto shop. I was told that my car would need new spark plugs and coils, and since it was due for an oil change I asked them to do that as well. I approved the work and was told it would be completed by the end of the day. So I returned at 4:30 and was told that the car needed much more work than originally thought. My service technician explained that the wrong spark plugs were put in by another auto shop which caused damage to the valve and/or cylinder and the engine needed to be rebuilt or replaced. He was going to get estimates for parts by the next day. The next day he said it would cost around $7,000. I told them no thanks and that I would have the car towed away that evening. In the meantime I spoke with the mechanic that put the bad spark plugs in and would have the car towed to them directly in order to fix the damage they caused and that I did not want to pay them to look at it. We got the car to them that night and the next day they worked on it. Late the same afternoon around 3:30 PM the owner of CSAI auto Jonathan called and said that his technician was wrong and that the spark plugs were not the cause of the damaged valve/cylinder. As soon as I got off the phone with Jonathan I called the other mechanic who had already been looking at the car all day and explained that it was not the spark plugs after all. By then they had already done a compete engine diagnosis and charged me $156 for it. CSAI charged me for their incorrect diagnosis and also the oil change since they had done the oil change before diagnosing the engine problem. Good thing my totaled car has fresh oil in it!! So the total came to $228. To add insult to injury, CSAI auto never applied the AAA discount. So the whole ordeal cost me about four times more than it should have. I would have given one star but Brittney and Jonathan were both very nice so the extra star is for them.

The people in the office were very friendly and had great customer service in person. Over the phone they are poor communicators. My car wasn t ready when it was promised and they told me I would not be able to drive it off the lot because my tires were in poor condition and I had to pay them to get the tires fixed before I drove it off the lot or pay their tow company to tow my car to get new tires. I will not be going back to them as I did not have a pleasant experience.

by - Verified Customer October 26, 2017

Excellent job. Facility is top notch!

by - Verified Customer October 23, 2017

Least to say that my car started running again and that is all I really wanted at the moment. Scared to go to the shop twice for the Same problem and was a shamed for a feeling I couldn't get out of.

This is a fantistic shop! I was traveling from Ct through Southern California and then to a trade show in Vegas. I started having car trouble on the highway and decided I needed to find a mechanic quick. I looked up reviews and they came highly rated. Knowing my situation they took me in right away, and correctly diagnosed the issue and I was on my way in no time. They did not try to up sell me or tell me I had an issue that I did not. EXTREMELY nice staff and I am so very happy I found them. I only wish they were in CT.

by - Verified Customer October 03, 2017

While the customer service was fine after the repairs and only 2 weeks I am having the same problem so my vehicle needs to go back to this shop. Not happy!

by - Verified Customer April 13, 2017

My truck was in the shop for an A/C issue. They found that the compressor was bad but there were still other issues that surfaced after they completed this repair. They got me in and spend all day diagnosing what the new problem was. Even though they spent all day on the diagnosis they only charged me one hour of labor for the diagnosis. They fixed the issue the next day and I have had no issues since. I was very satisfied with the work that CSAI did and will be back for repairs in the future.

by - Verified Customer March 30, 2017

Marianna's customer service was beyond compare! She's kind, thoughtful and made sure that my vehicle was ready in a timely manner! I made it to my appointment on time! Thank you, for treating me like family and not just a customer!

I brought in my recently purchased car to CSAI for minor maintenance and asked them to check another item I was concerned about. They took care of it all and once again I was glad I took my car into CSAI for their expert care.

Jonathan is a friendly and knowledgeable man. He explained and gave me options to repair the things wrong with my 1997 Audi. The ending price was less than he quoted. I have recommended him to my sister and friends. I have found my peace of mind mechanic. Thank you Jonathan & Patricia. Wish you abundance of blessings and happiness!

Their customer service is top notch. They were very kind and informative, giving me periodic updates while I was in the waiting room waiting for my car to be fixed. They also gave out free cinnamon cakes to us in the waiting room, something I have never seen a repair shop do.

My first experience was great! However, my second experience was shabby. I went in for a recheck on brake and lamp check and the guy was still helping everyone who came in even tho my car was done! I spent 40 minutes more than I should have after my car was complete.

by - Verified Customer May 26, 2016

Very professional and kept me informed as to parts required and updated me when parts arrived and were to be replaced. The entire mechanical personnel as well as the administrative staff expressed a sincere interest in my well-being while I waited for my vehicle to be repaired. An auto breakdown far from home can ruin a person's day. In this instance I experienced a very positive and uplifting day. I am indeed fortunate that Auto Club referred me to CSAI. Thank you you all.

The problem with my car was a simple one - the anti-theft code was scrambled so the car would not start. However, when the tow truck delivered the car to the mechanic, a large hole was punched into the oil pan. All of the oil leaked out on the mechanics' floor. I was told that they were able to start my car but that I had other major problems, and I was shown the hole in the oil pan and all of the oil on the concrete. They said I must have scraped the car on the driveway at the doctor's office where I had the car towed from. I said I was sure that was not the case, and asked if it might have happened from the towing. The reply was "You can never prove that.!" I had to rent a car as I was told it would take four hours to do the job, and they would have to do it the next morning. On my way home, I went by the doctor's office from where the car was towed, and there was not a drop of oil on the ground in the space I had been parked in, nor was there any sign of oil/drops of oil where the car had been pushed out of the space so it could be hooked up to the tow truck. With a hole that large, there would have been no oil left in the car when it arrived at CSAI. So, for the following reasons, I would not return nor recommend this mechanic:
1) He was dishonest, intending to cover up the damage created at his shop by the tow truck.
2) He overcharged for parts and labor. He quoted $231.11 for a used oil pan, and $349.77 for a new one. My husband went to O'Reilly's Auto Parts, and found that a NEW oil pay sells for $159.69 retail.
3) He said it would take four hours to repair the car, but could not do the repair until the next day, entailing a car rental. However, the car was not ready until the second day. So I incurred additional expenses of an extra trip to Riverside (90 miles round trip) and two-days rental car charges.
4) After noting that all the oil had been drained out through that large hole onto their floor, they still started and ran the engine, knowing that with no oil, it could damage or destroy the engine.

Initially I was happy with their service. Upon taking my car in for subsequent repairs, I wasn't impressed with their lack of communication in a timely fashion on what was wrong with the car and when it would be ready for pick-up. I had to call them several times to get an update on repairs needed and when it would be ready.
