Anyone in the Atlanta area recommend a reputable shop to work on my 2011 G37?
Car has 61k miles.

Having some strange issues where the car knocks from a standstill and then continues to knock into second gear. it's an auto.
Use 92 octane gas all the time.
No mods.
I bought one of the BlueDriver scanners comes up with U1000 Can communications Circuit: General Electrical failure. Whatever the F**! that means.
Which means there is an electrical failure somewhere. Ok awesome it's not like it's going to jump out and say. Here I am I am broken.

The car knocking from a standstill and it continues into second gear seems like maybe a cam position sensor issue?
Just driving me crazy. I can feel the lag of the car like it's missing then it clears itself up until I stop at the next light and slowly press the gas.
Still gets the same gas mileage
Never any issues with the car except I had a dead battery and got a replacement.
I don't mess with the car since it's a daily driver and if you are without a car in Atlanta you are SOL because it's a chore to get to work. This is a car town.

Any help would be greatly appreciated.

 

It's gonna sound obvious but I say take it in to the dealer. There are mixed reviews about some local shops but only the dealer and Z1 have worked on my car and Z1 is a bit of a hike plus you must have an appt in advance to go there.

 

I haven't used them personally (yet), but on the facebook group pages (Atlanta g's) it looks like Royalty Performance in Buford and Oden's Custom and Restoration in Norcross are highly recommended shops for general/custom things. But for that issue, maybe have the dealership themselves check it out?

 

Z1 is in Carrolton and a bit of a drive but they have a pretty untarnished reputation.

 

I'm giving Royalty Performance a shot, Z1 is so busy it's hard to even get into the shop. I called and the service guy was busy so they said email them and I did over a week ago and still no reply. I've been there before for work but their turnaround time these days is too long.

 

Countersteer LLC is also a great shop. That's where I had my car dynoed, and had the opportunity to see his work. Another option is also Evolved Tuning. All performance shops with good reputations.
