JEEP COMANCHE Recalls

The Jeep Comanche has 8 recalls covering the 1986-1991 production run, with the most serious being a throttle position sensor defect on 1989 models with the 4.0-litre engine and automatic transmission that can cause an unexpectedly high idle at startup, leaving the driver with reduced control if the vehicle is shifted into gear before idle speed drops. The 1986 model year has two additional safety concerns. The accelerator cable bushing can disconnect from the lever assembly, causing the engine to drop to idle with no way for the driver to control throttle response. Separately, the parking brake pawl can yield under load and allow the vehicle to roll away from a parked position. The remaining recalls across the production run involve emissions compliance. On 1991 models with the 2.5-litre engine, the mat surrounding the catalytic converter's internal bricks can erode from heat expansion, degrading emissions performance. The 1989 model year has two emissions recalls: one affecting the 2.5-litre engine and another affecting the 4.0-litre, both involving defective catalysts or oxygen sensors that reduce the system's ability to control fuel-air mixture and exhaust output. The 1987 model year with the 4.0-litre engine also has an oxygen sensor that can fail and reduce catalyst efficiency, increasing tailpipe emissions. The 1986 model year has a compliance labeling recall unrelated to any mechanical defect.
