My dealer advised that i3's require a bolt changed in the motor mountings plus software change.

It appears that if an i3 becomes airborne and under power the wheels spin up and on landing this puts stress on the motor mountings. I think the software change is probably to restrict the spin up of the wheels in such a situation.

It is probably a San Francisco owner doing a Steve McQueen stunt that found the weakness

Software change in part of Nov'15 update cycle.
My software version went from I01-15-07-502 to I01-15-11-502.

Not sure how much good it really does, as the REX engine mounts seam to be the consistent weak point. A new bolt is the step in the right direction. Upgraded engine mounts may be the ultimate answer, but its sounds like we are a few recalls away from that ;-).

So is it retaining to just the Rex motor or the electric motor?

If it's the Rex only then I don't need to worry.

504 is the latest update not 502.

Are you sure?
What's the full version #?

BMW seams to be rolling updates out in a 6-month cycle (May & November), and follows the version number naming convention of I01-YY-MM-502.

Here is the November'15 software update TSB:

This is the closest engine suspension movement illustration I could find:

You can see how REX engine is mounted on top of electric motors, and the entire assembly moves a LOT. Additional weight of the REX engine can not help but exacerbated the stresses on the engine mounts, so it's a contributing factor to their wear and tear. What I don't know is whether REX and BEV engines use the same engine mounts, or if REX ones are beefed up a bit (clearly not enough).

So far, the early engine mount failures have mostly been showing up on REX cars. But with that much lateral movement, it's only a function of time before they age, crack, and break on both types of cars.

Lol jeez the guy should have put some anti glair glass to seal off the engine access hole. I wonder if he later regretted that as to all the dirt and stuff blowing into the cabin!

I think it happened to my Rex today. Drivetrain malfunction message and then clunking noise from the rear of the car on acceleration, deceleration and turning. Getting it towed to the dealer tomorrow.

Report back what they find plz.

You do realize the car shown in the video is a BEV correct? The REX engine is mounted to the right of the electric motor in the empty space shown in the video.

BEV's, although less common, have also had engine mount failures.

Had the recall done last week and got the upgrade to the display (adds % and some power indicators) - from what I read the BEV gets one bolt changed and the REX gets two.

Hi I expect that was at Ocean how long was it in for?

Dropped my car off at the dealer for renewed rear suspension clunk, they claimed ignorance of any recalls or TSBs for my VIN.

Does anyone know the TSB / notice # for engine mount bolts?

TIA,

P.S.: Asked them not to touch the programming this time. I grew tired of reprogramming the car after each and every non-essential software bug fix.

Drop off at 9 picked up at 4....

The dealer found that the rear axle popped out. They opened a puma case with BMW. Waiting on the resolution...

[m5sdse63]

Dealer called today that transmission was damaged as well. They will be replacing the transmission and the rear axle.

Wow, this is a pretty drastic failure.
Did you go airborne or off-roading or something?

If yes, don't answer ;-)

No off-roading or anything unusual. Regular paved road with dips and bumps. Drive it just about every day. Clearly unacceptable for something like that to happen for any car.

It's funny but normally I would cringe thinking of having to replace these out of warranty, but since the transmission is only around 400 bucks it ain't an issue !


Crazy cheap! Engine is like $1500 That's all without the 20% off discount ! Can't believe their so cheap. Just the batteries you have to worry about as those are the guys that carry the cost!
