OK, I just posted this on another Drive Motor Malfunction post but it bears worth repeating on this forum:
I don't drive a REX, just a straight BEV i3; 2014 w/37,000 miles on it. About a month back it threw the Drive Train Malfunction code on me just trying to back out of a parking spot on a rainy Florida evening. The car wouldn't go anywhere. I called BMW Roadside assistance and they promised a tow to the dealer in 48 hours; so I called my car insurance company for a tow and they said "45 minutes". Fortunately I was walking distance home so I went back for my motorcycle. On the way back I thought I would try to trick it into Neutral and see if it started back up. I managed to, and it started up, so I called off the tow and drove it home.
About 2 weeks later I started off for work, and was just as I was about to turn right on to a busy highway (with no shoulder) when the car threw the code again and shut down. [The worst part is that as it stops it goes into PARK and there's no pushing it out of the way. (I have since talked to the dealer and BMW N. America about this and there is nothing they can do. It seems everyone hates this feature and complained to their dealer about it, so I reported it as a vehicle hazard to the NHSTA).]
Before I called the tow truck this time I waited about 15 minutes and it started back up, so I drove it home and parked it. I called the local BMW shop and they towed it in. The said there was some issues with the HV battery pack so they had to drop the whole pack and replace a half dozen sensors & modules. That took about 10 days. I got it back Saturday morning (yesterday) and drove it to work; no issues. Later that night I was headed back home and just started merging onto the local freeway (where I needed to cross 6 lanes of traffic to take a left-hand exit in about a 1/2 mile) when it threw the DTM code again!
Yikes! I puckered up like a carrier fighter pilot that just lost thrust on a cold cat-shot (I know, I used to be one!)
I had gotten up to about 60 mph and was just 2 lanes away from the turn lane when it threw the code and died. Even though the car wouldn't glide very well (like it would in Neutral) fortunately traffic was light that time of night and I had enough momentum to make the exit and glide to a stop. I called a friend for a rescue but just as he was getting into his car I got the car to start back up again so I drove it back to my work.
I'm going to call the shop again and have them tow it in [where they will probably just replace some other sensor, throw some more pixie dust on it and pray for a miracle].
First question: does anybody have an idea of what's wrong with the car? Obviously the dealer has no idea and BMW Germany is staying quiet. Any particular module or sensor they should be looking at or testing?
Second question: Now that I am officially scared shitless of ever driving this car on the freeway again (and it's my only car so I'll have to get around on my motorcycle from now on) does anybody know of any legal recourse against BMW in case it happens again AFTER they try to repair it again? I'm serious...I'd just as soon never drive this car again knowing what it does when it throws that code (especially for no real reason).
