The SRS (airbag) light can come on if liquids are spilled into the seat belt buckles, or if the liquid pools underneath the seat and gets into the electrical connector for the seat belt pretensioner. Damaged components will require replacement to restore proper airbag operation.

An engine oil leak may develop from the oil level sensor. Replacement of the leaking sensor will commonly correct this concern.

A dead battery can be caused by a faulty seat control module that does not properly shut down.  Spilling liquids on the front seats can cause these modules to fail.

The CD changer may suffer from an internal mechanical problem. Replacement of the faulty unit is generally required to correct this issue.

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

The heater case for the center vents can crack near the stop sensors. If the stops break, the control motor will not know when to stop and will run continuously.
The hold down nut for the upper front strut area can become loose, causing a knocking noise. This can be repaired without removing the strut assembly.
