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.

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.

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.
