Known Problems

Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

Some automatic transmissions may set a code P1740, torque converter fault. Our technicians tell us there is a revised transmission pressure boost valve cover plate to correct this condition.

The fuel tank may become hard to fill and/or the fuel fill nozzle may shut off repeatedly while fueling. Our technicians tell us that various items including the fuel tank, vapor recirculation tube, fuel fill tube, or EVAP system canister control valve may be at fault. Proper diagnoses will be required to determine the exact cause of this concern.

Various engine and transmission fault code issues and driveability concerns have been addressed with software upgrades. Our technicians tell us that in some cases the engine and transmission control modules must be programed as a coordinated change. Driveability concerns may develop if only one module is reprogrammed.

Rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.

The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.

If the door locks intermittently lock and unlock without pressing the door lock switch, the door and liftgate lock cylinder switches may need replacement. This may occur more often when driving in damp conditions like the rain or through a car wash.

The was a recall on some models to inspect the front, lower ball joints and replace any that are damaged.

Most commonly, drivers find that a clunking sound occurs when passing over bumps, and popping noises may be heard while turning the steering wheel. 

Aside from these noises, the vehicle may pull to one side while driving, and the tires may wear excessively on the inside edge. 

The worn out ball joints must be replaced to prevent risk of separation of the spindle and hub assembly from the lower control arm, a dangerous scenario at any speed. 

To inspect a connector for the cooling fan motor, Dodge issued a safety recall. Coolant may be drawn into the connector, causing a short circuit and potentially an engine fire. Dealers are installing a revised wiring harness and replacing any damaged fan motors.

If the vehicle will not shift into, or out of four wheel drive, and the "Serv 4WD" warning light is illuminated, the front axle disconnect actuator may need replacement and a power module (TIPM) may need a software update.

The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.

Vehicles equipped the ESP/Traction control system can be overly sensitive, activating on tight turns unnecessarily. Our technicians advise us that there is upgraded software available for the Anti-lock Brake control module to correct this concern.

The automatic transmission can develop problems like erratic shifting, rough shifting, or delayed gear engagement. Repairs for many of these problems are outlined in service bulletins.

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.

If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.

When driving over bumps a clicking or squeaking from the rear leaf springs may be fixed by replacing the (leaf) spring tip liners and installing a spring clinch clip (kit available from the dealer).

A damaged cam position sensor (or its wires and connector) can cause intermittent stalling, stumbles, or hard starting.

The auxiliary heater hose connections (that are routed to the rear heater under the vehicle) can develop coolant leaks.

Intermittently, the key may not start the car or release from the ignition. If it is excessively worn, replace the key. If the new key doesn't work, replacing the lock cylinder including tumblers should correct this concern.

Worn sway bar bushings or sway bar end links may cause a rattling or clunking noise from the front suspension during low-speed driving. Though not always the root cause, front struts are often replaced for this condition.

The rear evaporator tubes in the rear HVAC unit may develop small leaks, causing weak or no air conditioning. A new rear evaporator unit has been designed to address this and should be installed to address this condition.

A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

The fuel level sensor may fail resulting in erratic reading of the fuel gauge. Sensor replacement is generally required to correct this concern.

The BMW 335is turbo engine suffers from waste gate issues which become progressively worse with normal driving and especially with harsh driving conditions.

The turbocharger uses exhaust gas to create air pressure which is then forced into the engine. When there is no demand for power, the exhaust gases are released into the exhaust through a waste gate to prevent the turbo from speeding up.

“Waste gate rattle” or “Turbo rattle” is a result of excessive movement between the waste gate and the waste gate seat. This is a progressive issue with the following symptoms:

  • Rattling at cold start
  • Rattling upon deceleration
  • Loss of power
  • Check Engine Light Illumination
  • Manufacturer Specific OBD trouble code P30FF
  • Very poor engine performance and MPG

Adjustment of the waste gate actuator can solve the issue, but the issue will return. If adjustment does not correct the issue, the turbocharger waste gate must be rebuilt with new bushings, or the turbocharger must be replaced. BMW has replaced many turbocharger assemblies under warranty to correct this issue.

A creak or squeak can be heard from the top of the front or rear doors. This noise is most noticeable when the windows are fully up. The noise is caused by the decay of the flocking material on the door seals. New door seals, Teflon tape, special lube, or a combination of all of these may be needed to eliminate the noise.

Hyundai Tuscon gasoline models equipped with navigation units may suddenly stop playing audio from all speakers. This includes sound from CD players, radio, navigation, satellite radio, and telephone calls. All other features may still function properly.

Note: This does not apply to fuel cell vehicles 

This fault requires no part replacement, and is a software glitch that can be rectified by a 'hard reset'.

To perform the hard reset, simply disconnect the vehicles negative battery terminal, wait 15 minutes, and reconnect the negative battery terminal.

The crankshaft position sensor may fail, causing engine stalling or a failure to start. Replacement or the failed sensor will commonly correct this problem.

Toyota issued a recall on the lower ball joint due to the possibility of premature wear from improper finishing in production. The ball joints will be replaced under the recall.

One or more motor mounts may wear out on cars with high mileage. This will put extra stress on the other mounts, and the faulty mount(s) should be replaced.
