Hora while your logic is good and i agree to a point
My dad had a brand spankers van on a lease….
This thing had more electrical gremlins that god knows what , was a relief to hand the keys back.
After 2 years It did this thing where you would turn the key and “nothing”
Push it slightly and bump it a little and it would start fine sounded like starter solenoid fecked- but no….garage replaced heaps of the componants in that area inc clutch , flywheel, starter and alternator before declaring it wiring and it would need to go to vehicle electrician. Lease co got that back sharpish.
Ip also hunted at idle – they couldnt fix that either.
