Tire Pressure Monitoring System problems of the 2005 Jeep Grand Cherokee

Corroded and snapped tpms valve cap.

Checking the tire pressure in a customer's vehicle resulted in two broken valve stems due to deterioration of the tpms sensor.

I have a 2005 Jeep Grand Cherokee with tpms sensors installed. Apparently, metal caps were installed on the valve stems that oxidated together making their removal impossible without twisting off the valve stem, flattening the tire. I can't even get a replacement tpms valve replacement from Jeep (mopar) because they are on backorder (due to high demand because of problems like this). This creates an unsafe driving situation--I can't check my tire pressure because the cap is frozen on to the stem--if I try to remove it, the stem will break, and there is no supply of tpms replacement parts. These should have never been on the market installed this way-they should have had rubber/plastic caps installed.

I currently drive a 2005 Jeep Grand Cherokee laredo, and I have been having trouble with the tpms tire valve stem spontaneously breaking causing rapid deflation. So far two have broken, but fortunately the car was not moving on both occasions. It appears the valves broke due to corrosion. My concern is that this may occur at a high rate of speed, causing a loss of control.

The contact owns a 2005 Jeep Grand Cherokee. While driving approximately 55 mph on normal road conditions, the air bag warning indicator illuminated on the instrument panel. The indicator remained lit until the engine was turned off. The vehicle was taken to an authorized dealer for diagnostic testing. The technician stated that the failure was related to the air bag sensor and ordered the part for the repair. The failure and current mileages were 55,000. Updated 2/9/09 the tire pressure light illuminated as well. Updated 02/13/09.

Passenger seat belt light and red air bag light on dash comes on intermittently then stays on . Air pressure light comes on and tires are at normal psi. Some days both lights come on together.

: the contact stated while changing the gear from drive to reverse there was a clicking noise. This occurred intermittently. While attempting to apply pressure to the accelerator pedal the engine made a roaring noise and the vehicle failed to pick up speed. The dealership rebuilt the transmission, however no other repairs have been made. The manufacturer has been alerted. Updated 6/27/2006 - the vehicle battery would not hold a charge. The headliner had to be replaced because it was unraveling. . The sunroof motor had to be replaced. The transmission was rebuilt on 2-27-06 with on 90000 miles. The memory seat did not move back at times when the key was removed from the ignition. The tire pressure monitoring system was inoperative. The power steering pump was binding and had to be replaced. The air bag light illuminated on the dash. The rear windshield wipers were not flush with the windshield.

Red air bag light on dash comes on intermittently then stays on. Air pressure light comes on and tires are at normal psi. Some days both lights come on together. I have taken Jeep in four times for same problem in 17 months and its doing it again within 3 months of last service.
