So here is a bug I have figured out how to replicate. It is a little bit concerning. I wonder if anyone can take one for the team and try to replicate this too.
At work I park on an incline. Sometimes when backing out I get going a bit quick and then flip it into drive and just hit the accelerator. No harm done, it is electric. No gears to break, etc. It just slows the reverse movement then propels me forwards.
The problem is if you're going fast enough it will then say 1 pedal fault and turn off 1 pedal. Not a big deal, just restart the car and 1pd works again. Sets a code for torque calculation performance and 1pd performance.
There's the real problem though. Now cruise control won't work for several key cycles. The first time I did this it took about 18 hours and 3 key cycles to start working again. This time was 4 hours and 3 key cycles. When you turn cruise on it says "Adaptive cruise not available". Then if you go into sync and change it to regular cruise, when you hit the cruise button it STILL says "adaptive cruise not available".
So what the hell. I went and cleared all codes thinking it would fix it. Nope. Key cycled and checked for new codes NO CODES AT ALL in the system. Drove the car 20 minutes home. No codes in the system after driving home. Adaptive cruise still doesn't work. 4 hours later go drive the car and now it works. Still no codes. What is going on? how can they have a warning with no codes available?
What is even more odd is before I cleared them it had the DTC for torque calculation which said "MIL Is ON for this DTC". There was no kind of warning light on, only the cruise control warning.
Video of issue here (after the 1pd fault had been cleared):
My question is...can anyone replicate this? Go backwards at 5+mph then put it in drive and move forwards....Does it do the same thing? Obviously I know how to avoid this issue, but wondering if it is something I should show the dealer. They won't be able to fix it obviously but still it is interesting.
