NHTSA Complaint #10427172 — 2003 NISSAN ALTIMA

WHILE DRIVING THIS VEHICLE THE CHECK ENGINE LIGHT CAME ON. AUTO REPAIR SHOP READ CODE AS A P0420. TOOK IT TO NISSAN DEALER TO HAVE FIXED AND WAS TOLD IT WAS THE CATALYTIC CONVERTER AND BOTH O2 SENSORS NEEDED TO BE REPLACED AND IF NOT IT COULD LEAD TO PARTICLES GETTING INTO THE ENGINE AND RESULTING IN COMPLETE ENGINE FAILURE. AFTER LOOKING INTO THIS PROBLEM ONLINE TO SEE WHAT OTHERS WERE FACING, IT SEEMS THIS IS A VERY COMMON AND DANGEROUS PROBLEM. NOT ALL 2003 NISSAN ALTIMAS ARE COVERED UNDER RECALL OR WARRANTY, NOT SURE WHY ONE TYPE OF 2003 NISSAN ALTIMA WOULD BE COVER, BUT NOT ANOTHER. VERY FRUSTRATING AND SCARY, ESPECIALLY AS IT CAN LEAD TO A VERY DANGEROUS CRASH EVEN AT LOW SPEEDS. NISSAN IS NOT HELPFUL OR CARING TO THIS ISSUE AND BECOMES DIFFICULT TO DEAL WITH WHEN YOU EVEN FIRST MENTION IT TO THEM. SOUNDS LIKE THEY HAVE HAD LOT OF COMPLAINTS, BUT WILL NOT AND HAVE NOT DONE ANYTHING TO FIX IT. *TR
