2022 M3P 900 miles, Unresponsive

[M3Pro]

Couldn’t open doors, disconnect charge cable, access vehicle through app or keycard. Error descriptions attached.

No notable issues leading up to this or differences in my use or charging behavior prior to discovering the car wasn’t drivable this morning when I was headed to work.

Towed to SC this morning, have had no substantive updates or even diagnosis for over 5 hours now. Deeply irritating for an essentially brand new $70k vehicle. Wondering if these specific problems have come up for others?

SC said they believed it wasn’t just the 12v battery and required it to be towed in. Tow driver was able to access the vehicle and power it on to pull it out of my garage.

Lost contact with vehicle through the app overnight. Connected to my 14-50 the entire time.

I wouldn't think it would be the 12v battery causing problems anymore as the 2022 models have the 15.5v lithium battery now. Likely more serious as the service center said.

Got my sweet Uber credits so there’s that at least.

App is showing estimated completion by 6 my time tonight but who knows.

Sometimes new batteries just die. More likely a problem with the DC-DC transformer. If it fails the low-voltage side of the car runs off the 12v battery - until it is dead.

They need the car until July 11, hoping this isn’t the start of the stereotypical nightmare ownership experience that sees people sell theirs in under a year.

Hope not man. I had an impulse buy of M3P during their end is 2nd quarter frenzy. 400 miles already (90 mile commute each way to work) and no problems yet

I wouldn’t call this “stereotypical,” but certainly “nightmarish.” Hopefully it is fixable!

If it adds any optimism, I am at 5500 miles in my first 2 months of M3P ownership with no issues, including several road trips and one AutoX race day.

It doesn’t, but I do appreciate the anecdote. So far you’ve had an 80%+ better experience than I have.

Most likely an inverter issue. You see new owners with motor/inverter issues on here sometimes.

Update: they needed to replace the “power conversion system”? Lol

Still waiting on a completion eta.

That sounds not good. How could this happen to a new car less than 1k miles? Unbelievable.

I guess I was lucky.

 

[RayK]

That's called a Bathtub curve.

If it's any encouragement, I had something similar happen four years ago and then drove the car 200k miles with excellent (not perfect) reliability.

Got the car back on Monday, SA essentially just read the service notes back to me when I asked what the exact issue was or what could have caused it. Apparently the tech also broke a coolant pipe that needed to be replaced during the service.

From what I inferred, there was a low voltage battery issue. The tech advised me to keep cabin overheat protection on given the 110-plus temps in my area. Found that a little ridiculous that the going advise is heat can potentially brick these things but otherwise receiving no other diagnostic info— but I’m frankly over it /hoping for smooth sailing from here.

Best of luck. I turned off my cabin overheat protection with no issues. It's gotten up to 140+ in the Texas sun but since tinting its been around 115
