The dealer reported a misfire. Upon detailed investigation and a bore scope, the inside cylinder lining had disintegrated and metal shavings were in engine oil. The motor needed to be replaced. This took 30 days to receive new motor. Upon installation, the gear shifting linkage failed, necessitating removal and replacement of these parts. The issues are ongoing at this time and I still have not had the car returned to me. It is still being repaired nearing 45 days in the repair facility.
