2002 Chrysler Prowler Problems: 7 Known Issues

On the 1997, 1999-2002 Chrysler Prowler 3.5L SOHC V6, the rear-mounted 42LE (A606) automatic can drop into limp-in (fail-safe) mode when the electronic shift solenoid pack develops internal faults. Symptoms are the transmission locking into a single gear (commonly 2nd, or only 1st and reverse) until the ignition is cycled, often accompanied by a check-engine/transmission light. This is distinct from the fluid-overheating and AutoStick harsh-shift issues: here the solenoid pack itself (or its wiring/connector) is the root cause and typically sets solenoid-performance codes.

On the 1999-2002 Chrysler Prowler 3.5L V6, the Prowler uses a unique rear-mounted Chrysler 42LE 4-speed automatic transaxle with the differential integrated into the unit. The transmission is mounted at the rear axle (like a Corvette) for weight distribution, but the rear mounting location receives less cooling airflow than a front-mounted transmission. Combined with the 3.5L V6's torque, the 42LE overheats during spirited driving, causing shift quality degradation and premature clutch wear. This happens even though the car has a factory transmission oil cooler (Mopar 4786466AC on the 2002 Prowler).

On the 1997, 1999-2002 Chrysler Prowler 3.5L V6 (SOHC), the engine PCM (Powertrain Control Module) suffers an internal memory-chip failure that sets code P0601 'Internal Control Module Check-Sum Error' and illuminates the Check Engine Light, which also causes the car to fail most state inspections. Because the Prowler's PCM is a low-volume, long-out-of-production unit, replacement is a documented ownership headache.

On the 1997, 1999-2002 Chrysler Prowler 3.5L SOHC V6, the Prowler uses a cable-driven window regulator whose plastic cable-guide tubing and jacket are subjected to severe repeated bending stress. Over time the cable jacket cracks and the plastic guides break, so the window binds, drops, will not seal against the convertible top, or makes a faint ratcheting noise instead of moving smoothly. Because window position must match the convertible-top seal, a failed regulator also causes wind/water leaks. The OEM regulators are largely obsolete/discontinued, making this a high-demand pain point for owners.

On the 1997, 1999-2002 Chrysler Prowler 3.5L SOHC V6, the front lower ball joints are a widely reported weak point and were the subject of Chrysler Safety Recall C03 (NHTSA campaign 03V034000). Leaks or tears in the rubber boot let the joint lose its lubrication, causing accelerated wear. The joint can then separate from the steering knuckle without warning, dropping the front of the car to the ground and causing loss of directional control and a crash. Because the Prowler has a low production volume and aging fleet, this remains the single most safety-critical known issue.

On the 1997, 1999-2002 Chrysler Prowler 3.5L V6 (SOHC), owners report the in-tank electric fuel pump failing, producing a crank-but-no-start or hard-hot-start condition where the pump has power but delivers no pressure to the fuel rail. The problem is compounded because the original OEM Prowler fuel pump/sending-unit assembly is no longer available and correct aftermarket assemblies are limited, making sourcing a proper replacement difficult.

On the 1997, 1999-2002 Chrysler Prowler 3.5L SOHC V6, owners commonly report the fuel gauge not reading full after fill-up or reading erratically. The in-tank fuel level sending unit (and its O-ring, shared with early Harley V-Rods) is the usual culprit, and Chrysler released a fuel-control/regulator update to address the gauge not reading full. The gauge on this platform also does not respond when the sender is moved by hand on the bench, which leads to misdiagnosis.
