The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may state that there is a pop or tick type noise from the left front dash area over bumps. The noise may occur when backing out of a parking spot or going over small speed bumps in parking lots. The noise is worse when the vehicle is cold and may go away when the vehicle gets hot outside.
If you experience this concern and have exhausted all resources, the concern may be caused by a loose spot weld that attaches the "L" bracket from the left inner fender panel to the front bulkhead (See Photo Below)
(1) L Bracket without bolts.
Recommendation/Instructions:
To resolve the concern, add 3 bolts with nuts between the left fender bracket and the fender inner panel. This fender bracket is spot welded to the inner panel and attaches to the front-of-dash with 2 nuts (studs thru the dash panel). These 3 bolts/nuts were added through existing holes in the bracket and fender. ( See Photo Below )
(2) L Bracket with bolts.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
