Was notified by my mechanic that there is a nationwide shortage on Dodge Avenger engine manifolds. The manifold in my car had a huge crack and was emitting exhaust fumes into the cabin of the vehicle when starting up the car while the engine was cold. We could smell the fumes and it was making us sick. Our mechanic was not able to get a replacement for a brand new part and had it sent to a professional welder to fix the damage manifold in lieu of waiting a long period of time to get a new manifold sent to him.
