Some 2011 Hyundai Sonata vehicles equipped with a 2.4L engine may exhibit a rattle sound from the driver’s side of the engine compartment. This can be observed during certain engine operating speed ranges from 1,600-2,000 rpm or during light acceleration.
The rattle may be caused by the plastic fuel tube holder vibrating against the engine compartment bulkhead.
1. Open the hood and locate the fuel tube holder, which is attached to the engine compartment bulkhead (firewall). Confirm that the hook on the clip is loose and contacts the metal firewall. You may see a body paint rub mark at the contact point.
2. Mark the location of the fuel tubes directly above the holder with chalk or marker. Placing a position reference mark on the fuel tubes prior to removing the old part is recommended for placement of the new fuel tube holder.
3. Remove the old fuel tube holder from the rail using a trim removal tool and replace the holder with updated P/N 31356-3S000. Push the new fuel tube holder firmly over the mounting stud to ensure complete seating.
