 Heard a ticking sound coming from engine, sounded like an exhaust leak. took in for inspection was advised that there was a broken bolt on exhaust manifold in the rear. was advised it was not covered under warranty or extended warranty as it fell under exhaust and fastener components that are not covered. after searching the internet, i have found that this is a very common issue. this is a fire hazard and will cause me to fail emissions when i am due, which also violates the epa laws. i live in arizona where we do not have weather conditions that lead to rust issues. how can this be possible with such a large problem?? *tr

 After coming to a complete stop i press on the accelerator, at times i press harder and harder before the auto starts to move and it then goes much to fast. this does not happen at every stop. it is either in the accelerator or the transmission. the dealer ship can not make it duplicate the situation because it does not happen all of the time. *tr
