Get to the Root of the Problem

We Get To The Bottom Of The Issue

Many auto parts stores offer free diagnostic scans for dash lights like the check engine light. While these scans reveal vehicle fault codes, they do not pinpoint which parts have failed. At Zarn Automotive, our diagnostic services go beyond just reading codes.

Common Issues

Automotive diagnostics is similar to visiting a doctor when you're sick. You describe your symptoms (fault codes), and then the doctor orders tests like blood work and x-rays (diagnostic testing) to pinpoint the issue. Our experienced team at Zarn Automotive uses specialty tools and testing equipment to accurately diagnose and repair your vehicle. Common check engine light issues might include:

  • Loose or damaged gas cap
  • Faulty oxygen sensor
  • Malfunctioning catalytic converter
  • Bad spark plugs or spark plug wires
  • Issues with the mass airflow sensor
  • Faulty ignition coil(s)
Internal components of a motor vehicle

Great service! I had maintenance due for my Mercedes. I also had front and rear brakes replaced. Very easy to schedule an appointment on line. They are very thorough with checking on all the other areas for wear and tear. Michael/Neil were informative and very nice. I appreciated that they were even willing to stay over their regular hours to finish up the work So I could get my vehicle back the same day. Highly recommend.

I’ve been driving my 2013 ford escape that currently has 183,000 miles for a lil over 10 years. My goal is to drive her until at least 230,000 so I can say I drove her to the moon- ha!! She had been making all sorts of racket. Last year I took her into a mechanic who had some suggestions for repair which I did- but didn’t make much of a difference. This past Tuesday I brought her to Zarn & was blown away from the amazing service. He wanted to make sure we were in the same page for the weird clunking and noises I was concerned about & insisted we drive it around a little. I elected to do a diagnostic to also figure out what things I needed repaired to drive my escape safely. They have an awesome system that provides a link that lists each item with red (critical) , yellow (moderate), & green (good) along with the cost & you select the services you want repaired. It made figuring out what we wanted repaired very easy. I had new rotors, new brake pads & fluid, oil change and an engine mount repaired (it was collapsed) for a very reasonable price. I picked my Escape up & it felt like I was driving a totally different car. No more clunking and thudding- I am so impressed & satisfied with the services received & feel safe driving my escape. We will be bringing all vehicles to Zarn from now on! Thank you so much.

Amazing knowledge, precise diagnosis, professional grade work. Neil and the team at Zarn are awesome! This was my first experience with Zarn but it will not be my last. When no one would touch my hybrid Zarn did! May GOD continue to bless you all. Great overall experience!

Recommended by a friend, called them up late afternoon, told them I was having issues with my alternator. They had the part there the next morning. Dropped it off a little after lunch time and they knocked it out had my car back the next day. Everyone there was super professional and very nice to work with. They really want to take care of their customers and I feel they went above and beyond. Highly recommend going to these guys! They’re amazing
