Does anyone know if the most recent ecm update will help prevent the cracked piston issue that affected the 2016 and 2017 models? Also I cannot find accurate information on what percentage of the cars ended up needing this repair. My 2017 with 3300, yes 3300, miles had a hesitation problem that the dealership advised I have the ECM updated so I paid them $300 for the service. It did help resolve the hesitation issue but I am still concerned that I may have to deal with engine issues prematurely. From my research I believe this is related to the low speed pre ignition,lspi, phenomenon common with these cars. Any information or advice would be appreciated.
