2002 Chevrolet Monte Carlo Problems

What owners report

Owners of the 2002 Monte Carlo most often write in about electrical faults and brake/ABS problems, with a large share of reports describing repeated or intermittent failures rather than single breakdowns. Many complaints come from cars with well over 100,000 miles, though brakes, cooling leaks and turn signals often show up much earlier.

1. 1
   Engine

   Engine fires and oil on the exhaust manifold

   • 43 complaints (19%)
   • median 96,000 mi at 12.3 yrs old (33 state mileage)
   • 22 mention a crash, fire or injury
   • owner-quoted repair $680 (median of 5 quotes)
   • filed 2002–2024

   Owners describe smoke or flames from under the hood, sometimes shortly after starting the car or while driving, and some fires started while the car was parked. Several complaints note the car had received a notice covering the possibility of engine oil dripping onto the hot exhaust manifold, and a number state the repair parts were not available when they tried to have the work done. Complaints also describe oil leaks or smoke in the engine compartment without a fire. Reported from about 90,000 miles upward, with some cases under 70,000 miles.

   What to check: Ask whether the engine exhaust-manifold oil leak recall work has been completed and keep proof; check for oil residue around the front of the engine and watch for oil or smoke smells after driving.

   Owners describe the engine shutting off while driving, gauges sweeping and warning lights flashing, the anti-theft or security message appearing, and the car failing to restart until the battery is disconnected. Complaints also mention cruise control engaging on its own, wipers staying up or stopping, and door chimes with the key out. Some owners say the ignition switch was replaced and the problems continued. Reported across a wide range, mostly between about 75,000 and 170,000 miles.

   Brakes

   ABS and traction-control lights with loss of assist

   • 37 complaints (16%)
   • median 51,000 mi at 6.0 yrs old (27 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $775 (median of 5 quotes)
   • filed 2002–2019

   Complaints describe the ABS light, the service traction message and the TRAC OFF light coming on together, sometimes while driving and sometimes at startup. Owners say that once the lights are on, braking assist can feel reduced, the pedal can drop or the car can be hard to stop, and some also hear a grinding noise. According to complaints, dealers replaced wheel-hub speed sensors or the ABS module, and in some cases the fault returned. Most often reported between about 60,000 and 110,000 miles, though a few cases came much earlier.

   What to check: Start the car and confirm no ABS or traction lights stay on; ask whether the wheel speed sensors, hubs or ABS module have been serviced, and test-brake on a quiet road.

   “Loss of traction control and anti lock brakes in my car. My vehicle has allowed these safety features to quit working and after replacing the parts that the dealer said needed to be replaced, the vehicle's system does not recognize the new sensor and part, thus not allowing the traction control and ABS to work. After researching this on the internet, it seems to be a very common problem in GM vehicles.”

   NHTSA complaint #10275775, filed 2009-07, 95,000 miles

   “I went to turn and my service traction control and ABS lights came on. While turning, I lost power to the breaks and felt and heard a grinding/whining noise in the brakes and could not stop. The vehicle now has a whining noise when turning without braking at all.”

   Exterior lighting

   Turn signals and hazard flashers stop working

   • 23 complaints (10%)
   • median 88,000 mi at 6.7 yrs old (23 state mileage)
   • filed 2006–2016

   Owners report that the turn signals and hazard flashers quit with no warning, sometimes for a single trip and sometimes permanently. Several found that cycling the hazard switch would make the signals work again for a while. According to complaints, dealers often could not reproduce the fault, and some owners were told the flasher assembly inside the steering column needed replacement. Typically reported between roughly 45,000 and 115,000 miles, with some cases at lower mileage.

   What to check: Operate the turn signals and hazards before buying and watch for any pause or no-flash condition; ask whether the multifunction switch or flasher assembly has ever been replaced.

   “When I turn on the blinkers sometimes they work and sometimes they don't. When they don't no light comes on at all ( no blinker on the dashboard or on the outside lights). On numerous occasions my life flashed before my eyes when I was nearly struck by other vehicles while trying to make a turn and my turn signals weren't operating properly. I went to an auto parts store and they stated that the problem was a common one. They stated that it was the flasher assembly (in the steering column) costs $ 299.00. …”

   NHTSA complaint #10170793, filed 2006-10, 58,000 miles

   “My 2002 chevy Monte Carlo has been experiencing electrical problems since I have owned it. The cruise control comes on without being selected and then the heating/cooling systems goes off and on by itself. The turn signal goes on and off. Sometimes it will work sometimes it will not. The fuel gauge does not register correctly goes up and down so I am never sure what is in the tank. Occasionally the car will not start at all even though the lights work, the radio plays, and everything else will operate inside the car. …”

   Engine cooling

   Coolant leaks, intake gasket failure and overheating

   • 19 complaints (8%)
   • median 51,000 mi at 4.6 yrs old (15 state mileage)
   • filed 2004–2010

   Owners report low-coolant warnings, overheating, and rattle or knock noises on cold starts that fade as the engine warms. Complaints describe dealers finding coolant leaking into the oil or past the intake gasket, with repairs ranging from a gasket replacement to replacing lifters or the engine. Some owners were told the failure recurred after the first repair. Commonly reported between roughly 45,000 and 120,000 miles, including some cars under 60,000 miles.

   3 related service bulletins

   What to check: Check coolant level and color and look for residue around the intake and under the oil cap; ask whether the intake gaskets or head gaskets have been replaced.

   “We own a 2002 chevy Monte Carlo. The vehicle started to overheat. The dealer told us it needs a new head gasket at a cost of $1000.00 plus. I called chevy to see if this was a common problem since the car only has 50,000 miles on it and they said yes. They have not issued a recall. After doing research I have found out that many people are experiencing this problem and chevy will not fix this defect.”

   NHTSA complaint #10112728, filed 2005-03, 52,429 miles

   “Low engine coolant light coming on, intake gasket had to be replaced at a cost of over 800.00. Was told there have been multiple reports of this same problem, with no relief from the manufacturer.”

   NHTSA complaint #10145193, filed 2005-12, 118,000 miles

Buying note. These cars are old enough that service history matters more than mileage, so ask for proof that the ignition switch and exhaust-manifold recalls were done and check the brakes, cooling system and turn signals during a test drive. A pre-purchase inspection by an independent mechanic is worth the cost on this model year.
