Problems with 2004 Infiniti QX56 STRUCTURE

Tl* the contact owns a 2004 infinity qx56. the contact was driving 50 mph when the front end of the vehicle began to shake. the vehicle was taken to the dealer who performed a diagnostic that located the failure at the front suspension lower control arms. the vehicle was taken to the local mechanic to have the front lower control arms replaced. the vehicle was repaired. the failure mileage was 110,000 and the current mileage was 119,000. the consumer at his own expense, he had to replace the left and right control lower arms. the consumer stated a recall was issued in may 2010. however, he was informed that for his model the parts were not defective, and therefore did not fall under the recall. also, all four belt pre-tensions had to be replaced on both side. the consumer stated on four separate occasions the pre-tensions failed. each time they failed, it rendered the air bags non-functional. the transmission failed had to be replaced at a cost of $8000 due to the failure of a $10 switch inside the transmission, which was responsible for the reverse component. the wiper fluid motor was diagnosed as being inoperable. the consumer was informed it would require replacement at a cost of a few hundred dollars. the consumer received a second opinion and was told a hose had come off and re-attached it free of charge the entire brake assembly, driver side window motor, lift gate motor, tachometer, driver side door lock, hvac control, blower resistor and exhaust heat shield all had to be replaced. . updated 04/27/12

I have complained over the course of 4-6 months about the cruise control going out. it either goes out completely, or the cruise control without smart following goes out. when it does go out, bumping the increase speed button causes the engine to idle thuslosing speed. expecially bad on the interstate. the dealer claims they cannot find the problem (denied this problem 3 times now). seems funny when there is a tsb to cover the work. date here is date of last service to repair paint which is chipping off the front..down to bare metal, and then metal rusting...which is a whole different can of worms.

Problems with passenger side air bag.*mr since the vehicle was new the passenger air bag deactivation indicator light has illuminated on the dash intermittently. the rear lift gate sensor would beep while driving. the dealer was able to duplicate the problem but could not offer an immediate solution. the driver's side washer sprayer did not function. the liquid being sprayed out of the sprayer was alcohol which discolored the paint on the hood cowling. the dvd entertainment unit broke. while driving over bumps the vehicle would lose cabin pressure and emitted a low frequency booming sound. the consumer was advised that a technical service bulletin was issued for that problem. the dealer did not have the parts available to fix the problem. the vehicles engine made a pinging noise while the consumer was driving . the vehicle was taken to the dealer who indicated that they were waiting for an answer from the tech line. *nm
