Longmont Auto Repair

AA did a great job of fixing my top end after the dreaded AFM failure. Thx GMC for such a flawed system that breaks on almost all these series of trucks. All new lifters and push rods. Expensive fix, but well done. After the job, the o-rings on the injector(s) were leaking causing a pfft sound. Paid to have that fixed with new orings on all eight existing injectors, but after that, one of the injectors was running really rich and caused a permanent check engine light. Cory agreed to cover all the labor to swap out all 8 injectors whereas I covered the cost of brand new GM OEM injectors. A fair deal I felt. Dutch is a great mechanic.

Always a great experience. Professional, knowledgeable, and safety minded. It makes such a difference to work with a local small business instead of a factory dictated dealership! Im a fan.

These guys were super knowledgeable, and very pleasant to work with! I highly recommend!!

Saved the day on the Friday after New Years! Friendly and helpful, went out of their way for me.

I met one of the mechanics in an AutoZone parking lot, when I wasusing the diagnostic tool to check why my engine light was blinking right after having my catalytic converter replaced by my previous mechanic. The mechanic from this shop was able to offer to read the diagnostic tool and explain the problem to me. I asked him for his card and, scheduled an appointmentand they repaired my engine and importantly, gave me a good price and really made sure that I understood what was happening with my truck. Im very pleased to have found my new mechanic!

Quick and quality service. Would recommend to anyone who needs good service at a fair price!

Great response time, quality diagnostics, and effective repair. My automotive repair place of choice.

The team at Automotive Authorities always does a good job, minor or major. I have yet to find a better group of mechanics in Longmont.

Great service with honest folks at a fair price!

These guys are professional and quick and perfectly priced!
