Oct 2010 The vehicle started leaking oil from the head gasket, check engine light (misfire) indicated a problem with the valves not seating properly, loss of compression in two cylinders. Total estimated cost for this and other problems $12,000. Traded car. the transmission fluid was changed earlier in an attempt to resolve the jerky downshift-- as the vehicle slowed to a stop. This did not resolve the problem, suggesting that it was something more major. Needed new airbag module. Needed new ABS module.
