- [05V163000](/recalls/nhtsa/05V163000.md), 2005-04-22: SEAT BELTS:REAR/OTHER. ON CERTAIN CREW CAB PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE 2ND ROW CENTER OCCUPANT SEAT BELT ROUTING MAY MAKE IT DIFFICULT TO POSITION THE LAP PORTION OF THE SAFETY BELT LOW AROUND THE HIPS OF OCCUPANTS, ESPECIALLY SMALLER OCCUPANTS, SEATED IN THIS POSITION.   APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP.  IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT \(WITH CHILD SEATS OR BOOSTERS\), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL.  ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT. Built 2003\-04\-08 to 2004\-08\-04.

CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO\-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO\-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS. Built 2004\-02\-01 to 2004\-04\-30.
- [04V045000](/recalls/nhtsa/04V045000.md), 2004-02-04: SERVICE BRAKES, HYDRAULIC.

- [2005119](/recalls/tc/2005119.md), 2005-04-25: Seats And Restraints. On certain vehicles, the 2nd row centre occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants.  A lap portion of the seat belt routing that is not low and snug on the hips can allow unfavourable occupant kinetics in the event of a crash.  Moreover, the higher routing allows the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury.  Correction: Dealers will modify the guide loop.
- [2005033](/recalls/tc/2005033.md), 2005-02-15: Brakes. On certain vehicles, the hydraulic brake booster's pressure accumulator may crack and/or separate from the Hydro\-Boost assembly during normal vehicle operating conditions.  If a separation occurred and the hood of the vehicle was open, fragments from the accumulator could cause injury to people in the immediate area.  In addition, the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly.  The loss of fluid would cause increased steering and braking effort.  Correction:  Dealers will test and, if necessary, replace the Hydro\-Boost assembly.
- [2004037](/recalls/tc/2004037.md), 2004-01-29: Brakes. 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.
