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.

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. This vehicle has also lost power a number of times while driving, but those incidents didn't result in an accident (luckily). Thank you.

The exhaust manifolds are defective which creates noise and allows fumes to escape. Infiniti admits they are defective but they want $2,800 to $4,000 to replace them. This should be considered a safety hazard and infiniti should replace them free of charge.
