2002 Cadillac Escalade Problems
RepairPal has identified the most common problems with the 2002 Cadillac Escalade based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The power door lock actuators may become slow to operate or stop working completely and require replacement.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.
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.
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The sunroof may stop working for various different reasons. Our technicians tell us it is often better to replace the complete sunroof assembly than to try and repair the old one.
The headlight switch used on the Cadillac Escalade is known to fail through normal operation. Since the headlight switch is also integrated into the interior lights, a malfunctioning switch can cause issues with interior lights as well.
- Symptoms of a failed headlight switch include:
- Headlights and taillights failing to turn on or off
- Interior lights flicker, or fail to turn on or off
- Gauge cluster lighting off or flickering with headlights on
- Parking light malfunctions
This issue is well known with General Motors Trucks and SUVs, and is solved by testing and, if needed, replacing the headlight/dimmer switch. Bad grounding wires at the tail-lights, and dirty/corroded tow package wires can also lead to some of these issues.
The inside and outside door handles are prone to breaking.
