Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Damage to the tireâÂÂs valve stem may lead to loss of air pressure, which, if unnoticed, could lead to a flat tire or on dual-wheels an overloaded tire. In extreme situations, rapid loss of tire pressure could increase the risk of a crash. Operators may identify an audible rattling noise from the stem extension rubbing against the wheel opening while driving. Visual inspection during inspection or during maintenance may reveal stabilizer is dislocated, damage to the stem extension, or the rim, and low tire pressure of the inner tire.

Fuel module options FS90301 and FS90453 contain an electric fuel heater. Internal electrical heating within the fuel heater may create sufficient heat inside the fuel heater to cause plastic in the fuel heater to melt and potentially catch fire. It may also cause an engine stall. A fire, if undetected and uncontained, presents an increased risk of personal injury. An unexpected engine stall may increase the risk of a crash. If this condition exists, melting of the fuel heater or fuel seepage from around the fuel heater may be visible during a service event, smoke may precede or accompany a fire, or the engine may become increasingly difficult to start.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
