I'd like to do a Toyota owner survey. Are there those who own a Corolla that have had either engine oil sludge confirmed OR unexplained engine failure at fairly low mileage?
If so, please indicate the following:
1) model and mileage at the time of diagnosis/failure
2) new or previously-owned vehicle
3) circumstances surrounding the failure
4) Toyota's response
5) Cost of engine repair
6) approximate oil change interval
7) steps you took to document
Thank you for your information.
