1996 Nissan Altima Engine

RE: NISSAN ALTIMA 1996: THE CATALYTIC CONVERTER IS TOO NEW TO GO BAD AND THERE ARE TOO MANY BAD ONES SHOWING UP. I HAD TO REPLACE IT AT A VERY HIGH COST TO ME, WHEN THE VEHICLE WAS ONLY 6 YEARS OLD. *AK

CONSUMER STATES THAT WHEN SLOWING DOWN THE ENGINE REV'S REALLY HIGH. CONSUMER STATES WHEN PULLING OFF VEHICLE WILL JERK LIKE ITS A MANUAL SHIFT. PLEASE PROVIDE ANY FURTHER INFORMATION. NLM

THE REPAIR PERSON SAID THIS PART IS TOO NEW TO GO BAD AND THERE ARE TOO MANY BAD ONES SHOWING UP. THANKYOU FOR YOUR TIME. NO SAFETY DEFECT LISTED. *AK

POSSIBLE ENGINE FAILURE RESULTED IN ENGINE FIRE. *MJS

THE UPPER OIL PAN SEAL IS NOT SECURE. THIS CAUSES OIL TO LEAK FROM ENGINE. I AM FAMILIAR WITH FOUR OTHER INDIVIDUALS WITH THE SAME PROBLEM ( ALTIMA OWNERS). THE SEAL ITSELF IS VERY INEXPENSIVE, BUT THE LABOR TO LIFT THE ENGINE TO REPLACE THE SEAL, IS ESTIMATED AT APPROXIMATELY $450 TO $600. WITH FIVE ALTIMA OWNERS WITH THE SAME PROBLEM, I FEEL THIS IS A DESIGN ERROR. ANY HELP WOULD BE GREATLY APPRECIATED! *AK

ENGINE FAILURE RESULTING IN STALLING.
