Certain full-size passenger, cargo and cutaway vans may have front and rear seat belt buckles that will not latch or will not unlatch. There are two conditions that render the buckle inoperative after customer usage. Specifically, (1) with a damaged ejector hood, the latch tongue cannot fully enter the buckle and will not latch, and (2) if the release bar moves permanently out of position the buckle will either be unable to engage the latch or the pushbutton will be unable to unlatch the buckle. Correction: Dealers will inspect buckles and, if found to be inoperative, the entire buckle assembly will be replaced.

On certain vehicles, the relief valve o-ring seal within the brake hydro-boost module could fail. If this happens during braking applications, the driver may be able to hear an engine compartment noise similar to the sound that occurs when the steering wheel is turned to a full stop position. The driver could also experience a slight increase in steering efforts while braking and parking. Under certain driving conditions, a slight increase in the applied brake pedal effort may be required to achieve the same vehicle deceleration rate as prior to the seal failure. Correction: Dealers will inspect the hydro-boost module, and replace it, if necessary.

Certain vehicles do not comply with CMVSS 225 and 210.2. The Owner's Manual does not include the location symbols for the Lower Universal Anchorage System for Restraint Systems and Booster Cushions and an explanation of the meaning of the symbols. Correction: Owner's will receive an Owner's Manual supplement.

On certain vehicles, the seat belt push button may not release the latch plate after the pretensioner is deployed, or alternately the seat belt latch plate may eject during a crash event with a pretensioner deployment. If an occupant was using the seat belt assembly and the latch plate ejected from the buckle assembly during pretensioner actuation, the seat belt assembly may not provide a desired level of occupant restraint. If an occupant was using the seat belt assembly and the push button became stuck in the buckle assembly during pretensioner actuation, pressing on the seat belt push button would not release the latch plate from the buckle to allow the belted occupant to exit the vehicle. Correction: Dealer will replace the front seat belt buckles.

On certain vehicles, the right-hand tie rod end nut may not have been torqued to specification and could loosen, resulting in separation of the tie rod. This could cause unexpected steering input and could cause a crash without prior warning. Correction: Dealers will torque the tie rod end nut to specs.
