    Old, but dry Spark Plug

    CAUTION: As a college student that just moved to Riverside, I came here on 10/20, Monday to get my spark plugs replaced for my 2011 Toyota Prius. I used an OBD Scanner and it said there was a misfire on Cylinder 4. I had James (Jim) confirm and diagnose the problem. He said it was the coils that need to be replaced. The fix was about 900 dollars. I spoke with my father who lives far away and agreed that it was probably the coils. I was told it would be ready the next day in the morning. The next day on Tuesday, 10/21, I was hoping to get the car back in the morning. Called the place, I heard from the receptionist they needed more time. At around 3:45pm, I get a call from Jim that the head gasket and the coolant was leaked. The cost was gonna be around 4750 dollars. I let my father know to contact the place the next day. On Wednesday, 10/22, my father and I decided to check it for ourselves and I picked the car up. About 2 weeks later (November), we had the spark plugs replaced for 100 dollars because they were old, not wet. The head gasket was completely fine, dry and had no coolant. If the head gasket was bad, either the piston cylinders or the spark plugs would have been wet. TLDR: I would not trust the place. If it was not for our judgement and my father's expert knowledge on cars, we would have lost 5k just to replace the spark plugs which are an easy fix. They misdiagnosed the issues with the Prius and said the head gasket was leaked which caused the jerking. Do yourself a favor and take your business somewhere else. They will just charge you extra for no reason. Below are the OBD Scanner codes, dry spark plug (Cylinder 4) and the 4750 dollars invoice.

    This place is the best, Ive been coming for multiple years at the recommendation of my friend, and have also recommended them to multiple people, great prices and they have never overcharged me even once, they always check everything out for me free of charge and tell me its all good. Some people will take advantage of young women and overcharge them thinking they don't know anything about cars but these guys have never done that even once. Plus they have the best shop cat ever!

    Invoice for head gasket and fuel injectors

    BEWARE BEWARE Please do not bring your car here at all. A few weeks ago my son just moved to Riverside for school and I am 8 hours away from him. His 2011 Prius started rough idling and he checked with an OBD scanner and the codes were misfiring. So I told him to take it here and see how much it would cost to replace the spark plugs. After the owner diagnosed his car, he told my son that the fuel injectors are bad. So the quote was $600 for all 4 injectors. I told my son, I could live with that quote. The next day, the owner called me and told me that the car was overheated and it needed a head gasket. He told me that it"s $5,000 and I told him the car isn't worth that much. I told him its just the plugs needed to be replaced. I told my son to drive it back to his place and I will have it transported back to Sacramento. After I got it back, I replaced his car with 4 new plugs and ignition coils about $100. I reset the check engine light and take it for half an hour drive. It ran fine without any issues. A few days later I called the owner up and told him that it wasn't the head gasket. He started cussing at me.

    Took our Toyota Prius in because the engine was making a horrible thumping sound. They couldn't find anything wrong so no charge. Awsome!

    I recently brought my BMW to Ace Auto Services in Riverside after a frustrating experience at the…read moredealership, and I couldn't be more impressed with the care, honesty, and professionalism I received from Grace and Jeff. From the moment I explained what happened with my vehicle, they listened patiently, took the time to understand the situation, and walked me through exactly what needed to be done. They replaced the water pump and thermostat, kept me updated throughout the process, and even looked into the battery concern with complete transparency -- no upselling, no pressure, just honest advice. The car drives beautifully now -- smooth, strong, and better than it has in a long time. What stood out most is their integrity and personal attention during a time when I was already dealing with a lot. If you're looking for a mechanic shop you can actually trust -- one that treats your car like their own and gives you straight answers -- Ace Auto is the place. *Not to mention incredibly reasonable quotes/prices. Thank you again, Grace and Jeff. You've earned a customer for life.

After almost being ripped off by Toyota, I decided to give ACE Auto Service a try and I'm glad I did! I wish I would've gotten the name of the gentleman (maybe the owner), but right off the bat he knew exactly what my car needed and what it DIDN'T need. This shop just gained another loyal customer. Thank you!

She truly is an ultimate professional, and absolutely the friendliest, most helpful, and sincerely genuine! She is so knowledgeable and went through and broke every single service that needed to be completed down to me, so that I understood and we were able to come up with an implementation plan for completion at my pace. I cannot say enough good things about this shop and its owner. Her staff is also very knowledgeable and completed my repairs in a timely manner. She will go the extra mile to help her customers. Everyone who came into her busy shop received the same great level of care you could tell they were repeat customers. The shop is also great quality and value as far as pricing and work done. I will continue to use her and recommend her for automotive repair and Tire needs. I cannot say enough great things about her!

Trust this mechanic, I don't say that flippantly or without fantastic reason, which I'll share: I called to ask if I could bring her the used car I was considering buying from a local used car dealership to give the car an independent inspection. I simply said what I was hoping for, an independent inspection from a local mechanic (I live in Los Angeles & traveled out to Norco to look at this car), that I was looking for a used Japanese or Korean car, & my price range. As soon as I shared the name of the dealership (I didn't say anything about my experience or concerns with them, just the name), Kenni said she won't even do business with them, as they sold a used Mustang to her son whose clutch he asked them to fix, because he could tell it needed repair, they refused, and it went out about 800 miles after the warranty he purchased with this used car dealership expired, the clutch then costing $1000 to repair. Kerri also VOLUNTARILY gave me pointers for used cars, sharing that CVT's (Constant Velocity Transmissions, commonly known as Continuously Variable Transmissions) are not as reliable as other transmissions, which helped me narrow my search in cars in my budget. She also shared other GEMS of cars with recalls on engines, and how great she's found CLK 500 Mercedes cars to be. She has 38 years of experience. I passionately recommend for a trusted, capable, fair mechanic in the Norco, Corona area!!! She is my personal car buying angel of mercy.

They said if it's patchable yes, so I said I am 2 minutes away. I pulled up and let Alex know I was the one that called about the tire, all he said is what tire. I let him know which one and he removed it, patched it and let me know how much it was. Not very good customer service. He let me know it was a temporary patch. I told him I was looking into buying new tires, then his demeanor changed and let me know they have good deals. Will definitely not be going back. Only when they knew I was looking into buying new tires they conversed with me. Need some customer service training here. I don't know if it's because it was closing time and everybody wanted to go home but come on, change the hours then.

In some ways, I feel like the quality of work was even better than what I've experienced at a Tesla service center. They fixed the AC blower motor on my 2017 Tesla Model S and it made a huge difference right away. Everything was done efficiently and professionally, and they kept me informed the entire time. I also really appreciated that they use OEM Tesla parts because it gave me peace of mind knowing the repair was done the right way. What I loved most was how transparent they are. They use a system that texts you updates and actually shows you the parts that need attention, so you can see exactly what's going on with your car. It made me feel comfortable and confident that they were being honest and not trying to get over on me. On top of that, they took the time to provide me with a maintenance plan so I can keep my car in the best shape possible. That meant a lot because it shows they really care about helping you take care of your vehicle long term. If you have a Tesla or hybrid, I definitely recommend going to King of Hybrid Auto Repair. They do quality work and really take care of their customers.
