NHTSA Campaign #
Jaguar is recalling 112 MY 2007-2009 Xk vehicles fitted with run flat tires for failing to comply with the requirements of Federal Motor Vehicle Safety Standard no.138, "tire pressure monitoring system, (TPMS)." The TPMS warnings were turned off. If the TPMS electronic control unit were to send a signal to the instrument cluster to display a TPMS warning telltale, the light would not illuminate nor would the supplementary warning text on the instrument cluster message center be displayed.
Dealers will update the car configuration file settings to enable the instrument cluster to flag the warning symbols as required by FMVSS 138 and associated test in the instrument cluster message center. The remedy will be performed free of charge. The recall is expected to begin on or before June 8, 2009. Owners may contact Jaguar at 1-201-818-8500.
