Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 40 complaints with NHTSA since 2015. 23 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
My engine had a malfunction. My safety was put at risk due to not knowing if the vehicle would stop before I was able to safely get it to be checked. The dealer has been confirmed by the dealer as engine failure due to bearing failure. This was determined by metal pieces in the oil pan.
