Chrysler has issued various safety recalls for manufacturing defects that could result in Jeep Cherokee engine problems. Concerned drivers may contact the National Highway Traffic Safety Administration (NHTSA) to verify whether their Jeep transmission problems are associated with these or other recalls.
On February 5, 2008, Chrysler recalled 1,338 Jeep Grand Cherokees because of a manufacturing error in the front control module. This defect could cause the engine to stall unexpectedly, a potentially dangerous condition.
On September 8, 2005, Chrysler recalled 101,925 Jeep Grand Cherokees equipped with 3.7L engines and NAG1 automatic transmissions. A leak may develop in which air conditioner evaporator condensate water gets into the transmission and causes shuddering when the torque converter clutch engages. This leak can cause an engine fire if the water gets hot enough and transmission fluid is subsequently purged into the engine.
On March 2, 2004, Chrysler recalled 14,621 Jeep Grand Cherokees equipped with 4.0L engines due to a manufacturing defect in the crankshaft position sensor wire. The wire's insulation may crack and leave the wire exposed, which could lead to a stalled engine if the wire gets wet and the sensor malfunctions.
