The service was top shelf. The staff let me know what was going on with my vehicle.

I was due for plates this month so I Googled inspection locations and found Jammin J. I called made an appointment. It was just an emissions test but I was out of there within 15 minutes.

I drive from SOCO to see Doug/Cole and the crew. They keep me informed of upcoming needed maintenance or repairs. This gives you time to be prepared for expenses. They also handle immediate needs and work with you on schedule and discounts where they can.

I had a new repair needing a dealer part and inspection on my 2015 100,000 mile Ram. After going through inspection I needed additional work including ball joints and other steering parts. It was more than I hoped but they did everything they could to accommodate me including a loner car. I now feel confident that I got what i paid for and it drives like new.

Great service from Jammin'J.  They have really kept my 97 Ford running well and continue to do so. They keep a schedule for what needs to be done to it according to my driving habits. I appreciate that.

I’ve been taking my vehicles to Jammin J’s Automotive for the past couple of years. While I haven’t needed much work done, they’ve always been my go-to mechanic when something came up. I even recommended them to a colleague about a year ago, and he had several positive experiences with tire replacements and other miscellaneous repairs.

Unfortunately, his most recent experience completely changed my opinion of this business.

My colleague brought his vehicle in because the engine was overheating and appeared to be leaking coolant. After inspecting the vehicle, Jammin J’s was unable to locate the leak or determine the exact cause. Instead, they quoted him roughly $3,500 in repairs, involving extensive engine work, inspecting head gaskets, and replacing multiple components of the cooling system.

From what my colleague was told, they had not confirmed that coolant was leaking internally into the engine. Despite this, they recommended thousands of dollars in work, explaining that they couldn’t warranty the repairs without addressing multiple components of the cooling system.

When he told me about the quote, I thought it sounded excessive and recommended getting a second opinion.

The second mechanic found the issue within a couple of hours: a faulty radiator cap.

They performed a cooling system pressure test, the same type of test Jammin J’s had supposedly performed, identified the problem, and replaced the cap. The total cost was approximately $90. The vehicle has since been driven for over a week without overheating or showing any further signs of the original issue.

So how does one mechanic recommend $3,500 in repairs while another identifies and resolves the apparent problem for $90?

I can’t say whether this was an attempt to upsell unnecessary repairs or simply a failure to properly diagnose the issue. Either way, it raises serious concerns about the quality and reliability of their diagnostic work.

However, the misdiagnosis isn’t even the main reason I’m writing this review. Everyone makes mistakes. It’s how a business handles those mistakes that matters.

My colleague requested a refund of the approximately $80 diagnostic fee, considering another shop was able to identify the issue using a test Jammin J’s claimed to have performed. They refused.

Even worse, when my colleague emailed the business requesting a refund, his email was completely ignored. When he later called to follow up, the person he spoke with acknowledged seeing the email and reportedly stated that he simply didn’t care to respond.

That level of customer service is unacceptable, especially toward someone who had been a repeat customer.

I previously trusted Jammin J’s enough to bring my own vehicles there and recommend them to others. Unfortunately, after seeing how this situation was handled, that trust is gone.

A mistake in diagnosing a vehicle is one thing. Refusing to acknowledge a customer’s concerns or even respond professionally is another.

I will not be returning to Jammin J’s Automotive, and I will never recommend this business again. I strongly encourage anyone considering their services to get a second opinion before authorizing expensive repairs.
