A pickup truck includes a tailgate that is movable between open and closed positions. A powered latch provides for remote release of the latches of the tailgate. The tailgate is biased from the closed position towards the open position such that release of the latch causes the tailgate to shift automatically from the closed position to the open position.

1. A powered latch system for selective release of a tailgate of a pickup truck of the type that includes a vechilce structure including an upwardly-facing box and upstanding sidewalls extending along opposite sides of the box structure to define a generally upright rear box opening and a tailgate movably mounted to the vehicle structure for movement between an upright closed position and a generally horizontal open position, the powered latch system comprising: first and second latches having first and second latch members, respectively, that are movable between latched and released positions, the first and second latch members adapted to retain a tailgate in the closed position when the first and second latches are in their latched positions;at least one resilient member that is adapted to interact with a tailgate and bias a tailgate towards the open position when a tailgate is in the closed position and the latches are in the latched position;at least one powered actuator operably connected to the first and second latches to selectively shift the first and second latches from their respective latched positions to their respective released positions, whereby a tailgate automatically shifts from its upright closed position to its open position upon actuation of the powered actuator. 2. The powered latch system of claim 1, wherein: the powered actuator is adapted to be mounted to a central portion of a tailgate, and wherein the powered actuator is operably connected to the first and second latches by at least one elongated connecting member. 3. The powered latch system of claim 2, wherein: the one elongated connecting member comprises first and second elongated connecting members operably interconnecting the first and second latches, respectively, to the powered actuator; and including:a tailgate having a pivotable lever operably interconnecting the powered actuator to the first and second elongated connecting members. 4. The powered latch system of claim 3, including: a handle movably mounted to the tailgate, and wherein the handle is operably connected to the first and second latches whereby movement of the handle shifts the first and second elongated connecting members and releases the first and second latches. 5. The powered latch system of claim 4, wherein: the powered actuator is operably connected to the first and second latches whereby the powered actuator shifts the first and second elongated connecting members and releases the first and second latches without movement of the handle. 6. The powered latch system of claim 5, including: first and second strikers adapted to be rigidly mounted to a vehicle structure adjacent a rear box opening;the first and second latch members are adapted to engage the strikers to retain the tailgate in its closed position; and wherein:the resilient member comprises first and second resilient members mounted to the tailgate adjacent the first and second latch members, respectively, and wherein the first and second resilient members are adapted to contact the first and second strikers, respectively, when the tailgate is closed. 7. The powered latch of claim 1, wherein: the one powered actuator comprises a first powered actuator connected to the first latch and a second powered actuator connected to the second latch. 8. The powered latch of claim 1, including; a damper mechanism adapted to generate a force tending to slow movement of a tailgate from its closed position to its open position. 9. A tailgate assembly, comprising: first and second strikers;a tailgate having movable latch members at opposite side edges thereof adapted to releasably engage the strikers;a powered actuator operably interconnected with the latch members;a remote switch configured to actuate the actuator from inside a vehicle;resilient members mounted on the tailgate and deformably engaging the strikers to push the tailgate open automatically upon release of the latches by the powered actuator. 10. The tailgate assembly of claim 9, wherein: the tailgate includes a tailgate structure defining a generally quadrilateral perimeter with opposite side edges defining openings therein, and upper and lower edges extending between the opposite side edges, and wherein the latch members are mounted to the tailgate structure in the openings at the opposite side edges, and wherein the resilient members are mounted within the openings adjacent the latch members whereby the latch members retain the strikers in tight engagement with the resilient members. 11. The tailgate assembly of claim 10, including: a release lever pivotably mounted to the tailgate structure for rotation about an axis;first and second elongated members operably interconnecting the release lever to the latch members whereby movement of the handle or actuation of the powered actuator rotates the release lever and shifts the first and second elongated members to selectively shift the latch members from engaged positions to disengaged positions. 12. The tailgate assembly of claim 11, wherein: the release lever includes upper and lower opposite ends, and wherein the first and second elongated members are connected to the upper and lower ends, respectively, such that rotation of the release lever in a first direction simultaneously shifts the first and second elongated members inwardly to release the latch members. 13. The tailgate assembly of claim 12, including: a receiver operably connected to the powered actuator, wherein the receiver is configured to generate a signal that actuates the powered actuator if the receiver receives a signal from a portable key fob. 14. A method of opening a tailgate of a pickup truck of the type having a structure, a box, and a tailgate that moves between open and closed positions relative to the box, the method comprising: providing a releasable latch mechanism adapted to selectively retain the tailgate in its closed position when the latch mechanism is in a latched state;biasing the tailgate away from the closed position whereby the tailgate automatically moves towards its open position upon releasing the latch mechanism;providing a powered actuator that releases the latch mechanism upon receiving a signal from a remote source, whereby the tailgate automatically moves from its closed position to its open position upon actuation of a remote source by a user, even if a user does not pull on the tailgate. 15. The method of claim 14, wherein: biasing the tailgate away from the closed position includes providing resilient members that deform upon contact with the tailgate and the structure when the tailgate is closed. 16. The method of claim 15, wherein: the structure includes strikers that are engaged by the latch mechanism when the latch mechanism is in the latched state and the tailgate is in the closed position, and wherein the resilient members engage the strikers to bias the tailgate from the closed position to the open position. 17. The method of claim 16, wherein: the tailgate includes a rotatable lever that operably interconnects the powered actuator with the releasable latch mechanism; and including:utilizing the powered actuator to rotate the lever. 18. The method of claim 15, wherein: The remote source comprises a switch disposed in an interior of the pickup truck adjacent a driver's side seat.
