How frequent is the motor fail due to carbon/metal shavings ?
I'm looking to buy an i4, probably a 2022-2023 model, so out or almost out of the 4 year warranty by now, and this issue scares me a bit. I've seen people say BMW fixes it for free, others said it was a 3k€ job, others have been quoted 21k to replace the motor.
Is there any info on how widespread this is ? I read the 2022-23 models are more affected than the others, but I'm wondering if this issue is an "if" or a "when", as I don't want to buy a car and be quoted half its price 3 months later to fix this issue.
