If it is wiring, that can be hard to find or beyond what techs are allowed to do in terms of taking the car apart. It brings up a good question: what is a Supra-certified tech actually certified to do?
OP did state they changed the sensor and the issue was still there. Perhaps it could be some damaged wiring somewhere along the line that the tech didn't check. Saw no mention of that.
The part that failed was the BCM, which is effectively another ECU. They're meant to last the lifetime of the car (extremely high mean time to failure), so its not a part that readily needs replacements; profits or not, the emphasis for replacement parts go to items that are expected to break...
Did you need to jack the car up to install these, or remove/cut anything? Just curious to see if I can do this in my garage or if I need to get the car to the local DIY garage for more tools and lift access.
The battery isn't hard to access at all. It's an easy to remove cover.
Just curious, how much do you actually need to use the trunk? I had the same issue last year, even with my car as a grocery getter, and the passenger seat was good enough.
Let's not gloss over that the BCM is probably a part with a very high mean time to failure, meaning that its likely something that is only being replaced on order.
Also, it is an electronic control module, so there's a fair chance the war is impacting production of components for the module. I...
Good to hear Carvana is covering the cost. I think it was like $1500 or something if I had to pay out of pocket for a repair (mine was fixed under warranty). This was over a year ago and I don't feel like finding where I filed that invoice.
I'm surprised the dealer isn't fixing it through...

Might save you the effort of trying to figure out airflow. Just pop the plate off at the track. Leaves the tow hook slot open too.
The biggest joke is that people are photoshopping the price to be under the Z4 and M2 price point with an M4 engine.
Easily going to be $85k before markups.
