Summary
25630 – customer satisfaction program. These vehicles may have had remanufactured engines installed during a service repair that were built with incorrect piston rings. This may result in engine misfires, lack of power, rough running, oil consumption and eventually engine failure due to oil consumption. Dealers are to inspect engine serial numbers. If the serial number matches a list of suspect engines, the engine will be replaced.
