I WILL NOT DO MUCH COMPLAINING AT THIS TIME. I JUST FOUND OUT ABOUT THE PROBLEM AND I HAVE NOT TAKEN IT IN TO NISSAN YET. I HAVE BEEN HEARING THIS HUM AND IT GETS LOUDER AS I GO FASTER. I THOUGHT IT WAS THE TIRES, I DID NEED NEW ONES. I GOT THEM REPLACED AND A COUPLE OF WEEKS LATER IT GOT EVEN LOUDER AND I WAS AT LOWER SPEEDS. SO I TOOK IT BACK TO WHERE I BOUGHT THE TIRES SO THEY COULD CHECK AND BE SURE IT WAS NOT THE TIRES. THATS WHEN THEY TOOK IT FOR A TEST DRIVE, PUT IT ON THE LIFT, AND FOUND THE PROBLEM WITH THE CV JOINT. NOW I AM GOING TO TAKE IT TO NISSAN AND SEE WHAT THEY WILL DO ABOUT IT. WILL GET BACK AND LET YOU KNOW WHAT HAPPENS.
