When a warning light comes on, your Subaru starts running rough, or something just doesn't feel right, you need more than a quick code scan, you need a true Subaru diagnostic service from specialists who understand these vehicles inside and out.
At East Valley Auto Rebuild in Kent, WA, we combine 30+ years in the automotive industry with advanced tools and deep Subaru experience to pinpoint issues accurately the first time. Founded by Mark Bryant, the Independent Subaru Guru, and his wife Denise, our family-owned shop has been serving Subaru drivers from a 7,000-square-foot state-of-the-art facility in Kent since 2003.
We're "Your Sensible Dealership Alternative" for everything from basic check engine light diagnosis to complex Subaru engine diagnostics and computer-related issues.
Why Accurate Subaru Diagnostic Service Matters
Modern Subarus rely on sophisticated computer systems and sensors to manage everything from fuel delivery to stability control. When something is off, you'll often see:
- A check engine light or flashing CEL
- Rough idle, hesitation, or misfires
- Loss of power or poor fuel economy
- Strange noises, smells, or vibrations
- Intermittent problems that are hard to reproduce
A generic parts-store scan tool might give you a code, but it won't tell the full story. Real Subaru diagnostic service in Kent, WA means:
- Understanding how Subaru engine management and computer systems work
- Interpreting codes
and live data correctly
- Knowing common Subaru patterns and failure points
- Testing components rather than guessing and replacing parts at random
Our goal is simple:
quick, accurate diagnosis and transparent communication, so you know exactly what your Subaru needs, and what it doesn't.
Advanced Subaru Engine Diagnostics & Computer Diagnostics
At East Valley Auto Rebuild, diagnostics is one of our core strengths. We've invested heavily in state-of-the-art diagnostic equipment and top-grade measuring tools to ensure complete accuracy.
When you come in for
Subaru engine diagnostics or
Subaru computer diagnostics, we may use:

Advanced testing for ignition, fuel, air, and sensor systems
Compression and leak-down testing where needed

Transparent, Educational Subaru Diagnostic Process
Our philosophy is simple: no surprises, no hidden agenda, and clear communication at every step.
During your Subaru diagnostic service:
- You can
talk directly to the technician who's working on your vehicle.
- We'll
take you into the service area (when it's safe) to show you what we've found.
- We provide
photos and/or videos to document codes, failed components, or leak points.
- Mark often performs a personal inspection and is available to go over the findings.
- We give you an
honest appraisal of what needs immediate attention versus what can wait, so you can plan repairs according to your budget.
This is what we mean by
"The Curtain is Removed!!", you see exactly what we see, and you understand exactly what we recommend and why.
Honest Check Engine Light Diagnostics, No Guesswork
When your check engine light comes on, it's easy to feel anxious. Is it something simple, or a major problem?
At East Valley Auto Rebuild, our approach to Subaru engine diagnostics and check engine lights is:
- No parts cannon - We don't just throw parts at the problem. We test, verify, and confirm before recommending repairs.
- Clear explanation of codes - We'll explain what each code means in plain language and how it relates to your Subaru's symptoms.
- Prioritized recommendations - If multiple issues are present, we'll rank them by urgency and impact, so you can make informed choices.
- Respect for your budget - We understand real-world constraints and will work with you on a plan that makes sense.

See Why Subaru Owners
Keep Coming Back
The quality of work is top notch. Took my 2011 STI there to get the head gaskets done and could not be more pleased with the work they did and how they treated me through the process. Sent photos and videos of the entire process while taking apart the motor. Great people who really do want the best for the customer and their car. Would absolutely take my Subaru there again if needed.
I brought my 2017 wrx with a blown engine to Mark at east valley auto rebuild. I really liked how he took the extra time to discuss all my available options, from keeping it stock to going with more quality parts. Mark covered it all with his extensive knowledge while he tooks us out to lunch. He really made sure that what I wanted out of and from the car is what I got.
I have been coming to this repair shop for a couple of years now and just bought my second Subaru to allow them to keep maintaining my car for me. They have been so helpful to me over the years, always working around my budget, always squeezing me in last minute when they are busy. The owners are great people who genuinely care about their customers and the staff is very informative. Thank you, East Valley!
