Engine

“Camshaft sensor according to the Infiniti dealership (Ray Brandt on Causeway in Metairie La.) Is malfunctioning at makes the car engine die while driving. Then when you restart the car the engine revs fine in neutral but once in drive it won't go over 5 mph. Also the timing chain tensioner fails on this car and can cause severe engine damage while the car is being driven. I've looked up both of these problems and have spoken with Nissan and Infiniti and a simple internet search will also confirm that these 2 problems are extremely common on this 5th generation engine. Nissan even lost 2 class action lawsuits on the timing tensioner. Well if Nissan lost 2 court battles over an engine defect that every Nissan internet forum says is a very very common problem then why isn't there a recall. And shouldn't hazing headlights be a safety issue on ALL cars? Almost all cars have this problem and manufacturers keep building cars with UNSAFE headlights. Why aren't these recalls? Thank you for this website. As an American Citizen and consumer with a daughter these safety concerns are very troubling to me and all my friends and business associates.”

“THE CAR LOSES POWER AFTER A WHILE AND WILL JUST STOP AS IF IT RAN OUT OF GAS. THIS HAS HAPPENED SEVERAL TIMES, OTHERWISE THE CAR IS OK. THE MECHANIC SUSPECTS IT HAS SOMETHING TO DO WITH THE CRANK POSITION OR CIRCUIT BOARD. THERE WAS RECALLS ON THIS MODEL IN 11/2003 AND 12/2003 THAT DESCRIBE EXACTLY WHAT HAPPENS TO MY VEHICLE. THIS SLOWING DOWN TO STOPPING HAPPENED ON A MAJOR EXPRESSWAY AND I HAD TO BE TOWED. IT ALSO HAPPENED AGAIN IN MY STREET AND DRIVEWAY HAVING TO BE TOWED AGAIN.”
