Excellent service, OEM parts and no clones. Knowledgeable and competent with no nonsense. Happy to recommend to my colleagues, friends and acquaintances.

Carlos and Doug provided us with helpful professional guidance in determining how to handle a potential serious electronic problem and then completed the repair with utmost proficiency. During a previous routine oil service and maintenance inspection they had noted that the shocks were severely leaking and that front control arms were demonstrating signs of wear and play. We had this work done at the same time. The drive is much smother now with the suspension work completed, new tires and an alignment. Thanks!

Nice guys, conscientious, and the repairs were perfect!

Efficient and personal service.

Great service and communication. Highly recommended.

Carlos and his crew were fantastic. Very honest and keep me informed all of the way through the repairs. Highly Highly Recommend this company for your auto repairs.

Have been coming here for too many years to count. Wouldn't think of going anywhere else.

First class communication. Excellent diagnosis and fully warranted repair.

I have entrusted my vehicles to AEF for more years than I can remember now - from basic oil service and preventative maintenance to more complex mechanical or technical issues. This time around we had a very elusive key off battery drain issue that Hans and the AEF team worked on tirelessly until the problem was solved. All along the way I was kept informed of the "investigation" progress. The problem was solved and am once again confident that the car will not leave us stranded. Superb service and technical expertise as always. I would not have had this successful an experience elsewhere, especially at the auto dealership.

They know their stuff and have proven to me so many times to be trustworthy!

They AEF Team always makes sure my car is fixed properly.

I don't write many reviews, but I had to in this case. Words can't really express how pleased I am with the service I received from the whole team at Auto Fuel and Electric! I wanted to do a major refurbish on my 95 Camry. I love the car and wanted to keep it as long as possible. I was also on a time table to get it done. Once Doug, Hans & Aki got the vehicle evaluated, it turned out to be a great deal more work than we originally planned. Despite that, they did everything I requested (And believe me, that was alot!) and finished on time. I know they all put in a bunch of overtime to make sure I hit the road on time for the trip I had planned! The car runs and rides like new and my wife and I couldn't be happier! I would definitely recommend them for any of your car care needs! Thanks guys!

My family has been taking our vehicles to Auto Electric and Fuel for over 20 years. I took my truck in to have them assess what work needed to be done on my Silverado based on a report I received from a Chevy dealership. Carlos was amazing in answering all my questions and checking into every aspect with full detail and informing me what needed to be fixed now, what could wait, and what did not need to be fixed. Carlos and his crew were quick in diagnosing and fixing the issues that needed to be taken care of, in an honest and authentic way. I felt comfortable the entire time and was never pressured into making any decisions. Now I have my truck back and it is running amazing! Thank you.
