NHTSA Complaint #11625201 — 2016 RAM 1500

Purchased the vehicle used in 2020, and shortly thereafter, noticed the engine idling rough. Determined that the throttle body was loose on the (plastic ) intake manifold. Attempted to tighten the throttle body screws per manufacturer torque specs, but they were stripped. Investigating this, the design employs sheet metal screws into untapped plastic manifold holes. I had to use high temp RTV to secure the throttle body on to the manifold. This worked for a couple of years, but the throttle body became loose again. Tried to get a replacement OEM manifold from the dealership, but after several months, was told that the part was unavailable. More importantly, the same poor design is incorporated in the replacement part. I had to re-apply the high temp RTV in order to secure the throttle body on to the manifold for the truck to function. I believe that this poor design poses a safety concern because the throttle body could detach from the intake manifold at critical driving times. This design problem is widespread with all Chrysler V-8 vehicles, in several model years.
