Know before you go
Not sure what's wrong? Here's what we'd check.
Every car speaks up before it breaks down. Here are the signs we hear most — and what they usually point to. Spot yours? Bring it in and we'll pin down the real cause before any work begins.
-
Grinding or squealing brakes
Usually means worn pads or rotors — worth a look before it damages more.
-
Check-engine light is on
Could be minor or serious. We read the codes and find the real cause.
-
Running hot or overheating
Often a coolant, radiator, or thermostat issue — best not to keep driving on it.
-
Rough idle or stalling
Frequently a sensor, spark, or fuel/air problem worth catching early.
-
Pulling to one side
Commonly alignment, tires, or brakes — a quick thing for us to check.
-
New rattle, clunk, or knock
Usually a suspension, axle, or exhaust part telling you it needs attention.
We diagnose it, call you with the price, and never fix anything you didn't approve.

About Us
Honest Auto Repair in Denver — We Explain Before We Fix
We started Complete Auto Service on a simple idea: most people don't distrust mechanics because of the repair bill — they distrust them because nobody explains what's actually wrong. So that's what we do differently. We take the time to walk you through what your car needs, send photo updates when it helps, and never add on work you didn't ask about without checking with you first. Fair pricing, straight answers, and a car that runs right when you drive it off the lot. That's the whole job.
-
Local & reliable
Based right here in Denver — we answer the phone and show up when we say we will.
-
Honest pricing
Clear quotes, no surprises. You know what it costs before we start.
-
Quality that lasts
We do the job right the first time and stand behind our work.

Henok is a great mechanic. Fixed my 2015 Jeep Grand Cherokee overheating issues. He found another big issue while fixing it and asked me before fixing that too. He sent me picture updates, which is amazing. He makes sure your car is running smoothly before handing it back over. I'll be bringing my other cars here as well.
Henok is fantastic. Was super helpful and offered great pricing for quality work. Helped me find a vacuum leak I could not track down. Replaced both CV axles on my truck in a weekend when I know it was more work than expected with a rusty truck. I will always come back to him for car needs. Being super friendly and honest makes it even better. Could not recommend enough.
Henok was extremely professional and knowledgeable, was able to help me out same day at such a great price. He's the best.
Henok repaired and painted scratches on my bumpers and I'm very happy with the result. Great work, great pricing and fast, pleasant service. Would definitely recommend!
Henok was very friendly and my car looks a million times better for a great price. It was a bit of back and forth to get the paint just right but he was willing to work with me to get it right. I've recommended him to my friends already.
