The 1989 Jeep Comanche has 3 recalls, the most serious affecting trucks with the 4-litre engine and automatic transmission, where a faulty throttle position sensor can cause the engine to idle unusually high at startup, making the vehicle lurch or surge when put into gear.
The remaining two recalls both involve emissions equipment: catalytic converters and oxygen sensors on certain trucks may be defective and can cause the vehicle to exceed exhaust emissions standards. One of these applies specifically to trucks equipped with the 2.5-litre engine.
