RepairPal has identified the most common car problems based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
The interior wood trim and dash pad are likely to crack due to age and sun exposure.
Bogging, hesitation or stalling may be experienced during moderate to heavy acceleration. This can be caused by a failing of many sensors or modules in the fuel injection system. It is recommended to have an experienced shop perform diagnosis to find the root of the problem.
The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 1999-2003 models is #4114K (trade number).
On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.
There have been some issues reported with the electric sliding doors. Our technicians remind us that proper diagnoses will be necessary to determine the cause of various faults which may occur.
The center multi-function display may failure. This is commonly caused by poorly soldered internal connection. Our technicians tell us that these display panels can be successfully repaired or reconditioned by a shop specializing in such repairs.
The automatic transmission used in these vehicles have had a high failure rate. Failures can be due to internal component or electrical component failure.
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.
It is not uncommon or the power window motor and/or regulator to fail. In most cases the door panel will require removal to determine the exact failure.
Shifting harshness and shuddering issues related to the operation of the automatic transmission have been addressed by factory service bulletins. The shuddering can feel like the vehicle is being driven over rumble strips.
There have been numerous complaints of early transmission failure, even with with normal servicing. Issues start with a whining noise, overheat warnings, and an inability to accelerate. The most common solution is replacement of the transmission. Late 2014 model year Patriots changed to a non-CVT transmission.
A spring in the seat belt buckle may wear or fail, causing the airbag light on the instrument panel to illuminate. Failed buckles will require replacement.
The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.
The intake temperature sensor may fail resulting in illumination of the Check Engine Light and various driveability concerns. Our technicians tell us the intake air temperature reading on the scan tool should be within 10 degrees F of the actual ambient temperature, if it's not the intake temperature sensor should be replaced.
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.
The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps.
A Loose or worn gas cap may cause Check Engine Light to illuminate. At this time, RepairPal cannot confirm a recall for this gas cap issue.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The power door lock actuators may become slow to operate or stop working completely and require replacement.
