Q: Air-ride air line blew out
Answered by Rocco
There can be several reasons why the air suspension in your son's Infiniti is not functioning properly and a broken air line can definitely be one of them. Along with that, it is also possible for the air strut or...
Q: Not shifting from neutral
Answered by Spencer
Hi, I would check and make sure your brake lights are working. Most cars won't let you shift gears if the computer doesn't see that your foot is on the brake. The computer knows if you are on the brakes...

Hi there, many others have reported shaking during idle with the Q45 around that time. Replacing the coils has been reported to fix the issue, however there are other components that could be affecting the engine's smoothness as well so...
Q: Replaced alternator but still not sending power to the battery.

Trusted by thousands of happy car owners



Ben was great. He arrived early, completed the work quickly & cleanly, and was quite amiable. I didn't have to leave my home and got the maintenance completely with ease - 5 stars.



Whitney was obvious exsperienced and knowlegeable of the problem. His actions was that of a true profesional



I have to be honest, this was the first time that, I have EVER felt 'at-ease' around an auto mechanic. Jonas was thorough and straight forward with me about the issues; gave me a quote directly after doing the diagnostics on the car and, as it turned out, it cost me less than the original estimate. When does that ever happen with auto repairs ?? He was friendly, informative and knowledgeable. You folks made the whole experience convenient and painless. I'm "sold" on the "Your Mechanic" concept. I'll probably never take my car again to a traditional mechanic !! Jonas was a pleasure to deal with !
