Diagnostic services service near South Gate, CA

Jesse and his team are top notch! I have been bringing my nissan altima to M&J for the past year and very happy with the work and attention to detail. 5 stars!

Not happy with this place or the work, took my M3 there one time, and that was all it took. First off I had plenty of work done, header install, carbon intake installed, water pump, coolant hoses, O2 sensors, thermostat, crankshaft seal, and instructed him to repair the oil leaks. Ed says he repaired my oil leaks, yet my car continues to leak oil, he damaged a $400 wheel, which he said, if the shop he knew, could not fix it, he would buy me a new one. When his shop failed to do so, I asked about a new wheel, of course he then said, he had no money to get me a new one, so I paid out of my pocket for a new wheel. I had him install my carbon air box, and he removed my OEM clamps, threw them away and replaced them with some junk hose clamps, stating he did not have the tool to replace the clamps, not sure what that has to do with me. So I took my car to check on the oil leaks and was told and shown by the shop, how the oil pan was not only missing bolts, but some were sheared off from over torquing, I was also missing header and sway bar bolts from his header install, my power steering hose was not secure, causing it to rub on part of the motor, damaging it, there were a few other things he failed to do, now costing me over a $1000 to repair after paying him over $2000 for less than subpar work. Do yourself a favor, and stay away.

Great job! Fixed an ongoing problem with my brakes at a good price. Honest, same-day service.
