- The problem
- Due to improper material construction the hydro-boost fluid return hose may not be capable of withstanding the temperatures and/or pressures experienced with the hydro-boost system. Also, the hydro-boost fluid high pressure hose assembly may have been mislocated, allowing the assembly to contact the frame side rail. Abrasion resulting from continued contact along with improper material construction may cause pressure hose failure. Either of these conditions may cause hydro-boost fluid leakage, resulting in the loss of power assist for the steering and braking systems. Complete loss of steering or braking will not occur since both systems would revert to manual operation.
- The fix
- The dealer will install a hydro-boost fluid return hose constructed form the proper material, positioning the hose assembly to ensure adequate clearance between it and the frame side rail.

Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- Improper routing of the "hydroboost" hydraulic system high pressure hose assembly could allow a tubular section to contact the frame side rail. Abrasion from the contact could result, causing a leak in the hose assembly.
- The fix
- The dealer will reroute "hydroboost" high pressure hose assemblies and any damaged hoses will be replaced.
- The problem
- An intermediate steering shaft containing a mismatched pot coupling assembly may have been installed on the involved vehicles. This coupling may have an oversized serration diameter. An oversized serration could prevent the coupling from adequately tightening onto the gear or shaft splines.
- The fix
- The dealer will inspect and, if necessary, install a replacement shaft coupling.
- The fix
- Dealer will inspect the fuel tank vent systems for blockage and correct, if necessary. Fuel tanks will be inspected for cracking of the front panel and replaced, if necessary.
- The problem
- The fuel tubes (fuel tank to pump) on the involved vehicles may be routed such that tube to underbody reinforcement flange interference may result during vehicle operation. Tube abrasion caused by such interference may result in fuel leakage.
- The fix
- Dealer will reroute the fuel tube or install a new fuel tube, if damaged, without charge to owner.
