The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment of a rattle or clunk noise from the front of the vehicle. This noise can be easily mistaken for a front suspension component or stabilizer links. The noise may be the result of the hood rattling within the hood latch or at the
front corners of the hood.
Recommendation/Instructions:
- Lubricate the center hood latch and the hood bumpers at the front corners. Re-evaluate the concern.
- If the noise is still present, adjust the hood latch to draw the hood tighter to the body. Re-evaluate the concern.
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.
