Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
The Door Locks May Cycle Rapidly
Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. The affected door latch should be replaced to correct this concern.
Covering For Center Console May Bubble/Discolor
The covering for the center console can bubble and discolor. Replacement of the affected part is most commonly only way to repair this concern.
Transmission May Leak Fluid and Damage Control Module
The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. At that point, a new harness and control module may be necessary to correct this problem.
Rear Corner Panels on Sides of Tailgate May Crack/Break
The rear corner panels on either side of the tailgate (black plastic) can crack or break. They should be cut off and the adhesive removed before new panels are glued on.
Release Cables For Rear Seat May Stretch/Break
Release cables for the rear seat (second row of seats) tend to stretch or break requiring replacement.
Power Steering Return Hose May Leak at Radiator Cooler Fitting
The power steering return hose may leak at the radiator cooler fitting. If the clamp is not properly tightened, the hose can blow off, causing increased steering effort and a mess under the hood.
Oil filter housing may develop oil leaks
"No start" Due to Anti-Theft System Fault
A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.
Power Window Main Switch May Fail
The power window switch may fail and the windows will not raise. The main switch at the front center console is commonly at fault. A failed switch will require replacement.
Brake Light Switch Failure May Cause ESP/BAS Warning Lights
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.
