This PI was superseded to update model years. Please discard PIC4160A.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.


A customer may complain that after pressing the "Trunk Open" button via the switch inside the vehicle or the key fob, the rear Deck Lid will not stay open after it reaches the full open position. This could be the result of a weak strut that supports the deck lid when open.

Note: Under certain conditions when operating the power folding top, the power hydraulic system will support the decklid in the full open position. When opening the deck lid under normal circumstances (key fob or button), the deck lid is supported open by the hydraulic struts on each side.


Be sure the retractable roof is fully opened or fully closed and there are no messages on the DIC for the retractable roof. Open the rear deck lid via button or key fob and support the deck lid to the open position. Remove the deck lid gas struts and inspect for a "weak" strut. Replace only the strut that appears to be "weak".

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.
