Quick answer

Some vehicles may exhibit scratches (1) on the rear of the seat back bar garnish (2) from contact with the convertible top (3).Due to assembly variations, the clearance between the seat back bar garnish and the convertible top is too small on some vehicles.On later 2016 models (starting with VINs JM1ND******117681), the link stopper of the convertible top has been changed to adjust the opening angle and folding position of the convertible top. This increased the gap between the seat back bar garnish and the convertible top when folded down. On these later models, the issue seems to occur if the customer does not completely lock the convertible top down when lowered. NOTE: Make the customer aware that the top needs to be completely locked down when lowered to prevent this from happening. With the convertible top lowered, press down on both the front and rear areas of the top (as shown with the arrows) until a latch sound is heard and the top does not pop up.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
