Comment : Have been here a few times. Staff has always been honest and respectful. They have helped with AC issues in the past and also smog checks. First time I worked with Ricky, he?s has been easy to work with and the communication has been good. Haven?t had anything negative to say about this place yet, that?s why I?ve been back a few times. I would recommend.

Comment : I had been dealing with an issue on my truck for months and tried diagnosing and fixing it myself, but these newer trucks are just too complicated (and cramped) to keep tearing into at home. I?ve got a 2022 Ram 1500 3.6L V6 with eTorque?which sounds new, but with 153,000 miles I drive it a lot.
I narrowed the problem down to the EGR system and replaced the EGR valve myself, but the issue didn?t go away. After more research, I realized the EGR cooler and tube were likely the real problem, and that was more than I wanted to take on. I used the AAA website to find a certified shop and came across Ten Four Auto Repair Center.
I stopped by late afternoon, explained everything I had already done, and left the truck with them to diagnose. Ricky was very friendly, easy to talk to, and explained everything clearly. To my surprise, he called me the same day with a diagnosis and a repair quote. What really stood out was that he walked me through some optional items that could be addressed while everything was already apart?and explained why it would save labor in the long run. No pressure at all.
Honestly, their diagnosis lined up perfectly with what I was expecting. The ?optional? items he mentioned were things I already knew needed attention but had been putting off. He was absolutely right?it made sense to do them now.
The work they performed included:

Replacing the EGR cooler (common issue on these engines)
Cleaning the EGR system and intake ports
Walnut shell cleaning to remove heavy carbon buildup
Spark plugs (you have to remove the entire intake on these)
Valve cover gasket replacement (they were leaking)
Transmission fluid service

Looking over the work, everything appears top?notch, and the truck is running noticeably better. They had it ready in a couple of days, and communication throughout was open, upfront, and professional. No high?pressure sales, no surprises.
The work itself isn?t cheap?but when you break it down, the pricing was fair and in line with the scope of work, especially considering the quality and the fact that it was done right.
I?d definitely recommend Ten Four Auto Repair Center. They took great care of both me and my truck, and I won?t hesitate to bring it back when I need work done again.
