“The vehicle died when at a stop light and rolled back hitting the car behind us. I looked on your website and apparently it was caused by a faulty engine control module (ECM) in the intelligent power distribution module (ipdm). This appears to have been recalled on all 2004 to 2006 Infiniti QX56 vehicles, however, I received no such notice and Infiniti says their is not recall associated with my VIN number. I believe my VIN number was left out in error and this should be recalled. …”
NHTSA complaint #10761546, filed 2015-09, 130,000 miles“Emergency brake: e-brake appears to engage on its own and the brake light indicator comes on. There's also a grinding sound when brake is pressed. Grinding sounds only occurs when this issue comes up. Exhaust manifolds: was notified by the dealer upon a service inspection that there was a small crack in the exhaust manifolds. Is this a normal thing? And should this be a recall item as it could throw off any smog check testing. In addition how about the exhaust in the cabin issue? Maybe they used too thin of a metal for the manifolds.”
