The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

In order to correct a problem that results in difficulty starting, engine vibration, or a rattling sound from the engine compartment, Kia released an updated crankshaft pulley bolt.

The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

The service 4WD system light may illuminate with no fault codes stored in the final drive control module (FDCM). Our technicians tell us a software update for the FDCM is available to correct this concern.

A side door window regulator may fail causing the window to stop working, in some eases falling into the door. Replacement of the failed regulator will be required to correct this concern.

A defective turn signal lever (multifunction switch) can cause erratic operation of the turn signals and other exterior lights. Depending on the fault, a dead battery could result. Our technicians recommend replacing the failed switch.

Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.

The electronic level ride system may not work properly; this may result in the rear of the vehicle riding too high or too low. Our technicians tell us that a height sensor or exhaust valve failure are common issues with this system. Proper diagnoses will be necessary to confirm the exact fault.

Delamination of the diesel fuel tank can occur resulting in a loss of power due to debris clogging the fuel filters. In some cases the fuel injection pump and/or fuel injectors have also been damaged. Ford has issued a service bulletin (#19728) addressing this concern. This issue can affect all diesel F-350, F-450, F-550, F-650, and F-750 Super Duty models.

The CD player in the radio may fail. Our technicians tell us that the radio will need to be removed and sent out to a radio repair shop to correct this condition.

The intake manifold gasket can develop external engine oil or coolant leaks. In some cases the failed gasket will leak coolant internally. The manifold gasket will need to be replaced to correct this issue.

A plugged AC evaporator drain tube can cause a water leak inside the car; usually near the front passenger's feet.

The sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.

The driver's door latch assembly can break internally, which causes the door to stay closed. The interior and exterior door handles do not work to open the door. Our technicians note that the door panel must be removed while the door is closed (likely damage will occur) and the latch assembly must be drilled in a specific spot for the door to open.

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

Inside grab handles, the upholstery on the center console cover, and door trim panels can delaminate. Most commonly replacement of the affected part is necessary.

The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.

Worn door lock tumblers can cause the door lock to be sticky or not work at all. The lock has to be removed and the tumblers need to be replaced for this issue.

If the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.

A knocking sound my be heard from the engine at times with the air conditioning on. The cause could be the AC compressor itself, if that is the case there is an updated AC compressor to correct this issue.

Exhaust manifold bolts commonly break, exhaust manifold gaskets should be replaced and replace bolts as needed.

The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Low fluid level in the differential or transfer case can result in bearing failure. Damaged bearings commonly cause a whine or growl type noise.

There are reports of failures of the CCRM or Constant Control Relay Module.  The CCRM has relays and switches inside that control or provide power to the engine cooling fan, AC clutch (to engage the AC compressor), fuel pump and powertrain control module (PCM).  Single switches or relays can fail internally causing a number of different symptoms including no start conditions (inoperative fuel pump or PCM), engine running warm due to inoperative cooling fan, or the AC might not blow cold air.
