I TOOK THE VEHICLE BACK TO NISSAN AND THEY SAID DUE TO MY HAVING INSTALLED AN AFTER MARKET AIR INTAKE THAT MY WARRANTY WAS VOIDED. MY WARRANTY STATS THAT ANYTHING I DO TO THE ENGINE THAT CAUSES THE PROBLEM VOIDS THE WARRANTY. I WENT TO THE BBB,ATTORNEY GENERAL AND THE COMPANY CEO. NISSAN REFUSED TO FIX IT OR ANSWER THEM WITH AN EXPLANATION. I DID NOT GO BACK BUT TWICE AFTER THE WARRANTY WAS EXPIRED AND THEY KNEW THAT THEIR EARLIER DETERMINATION WAS WRONG SO THE JUST REFUSED TO ANSWER ANYBODY. I HAVE OWNED SIX NISSAN BUT NOW I NOR ANY OF MY FAMILY OWN ANOTHER. I AM PUTTING THE VIDEO ON THE NET SOON. I AM APPALLED AT THE FACT THAT NISSAN STILL CALLS ME TRYING TO SELL ME ANOTHER. ACURA HERE I COME!
