Emission Control Problems of Jeep Cherokee

While down shifting to second gear at 40 mph, the engine accelerated at a higher rate. The consumer pulled over and had the vehicle towed. The consumer had taken the vehicle to a private mechanic and did not plan on contacting the Jeep dealership about the problem. The cause was not determined. The vehicle was slowed down when the engine started revving, it was then switched to a lower gear and proceeded, then was placed back into drive in which it was slowed down and the engine started revving again in a lower gear but did not work. The vehicle would jerk and knock when placed in the engine when placed in park. (the u-joint failed) the consumer was informed the vehicle needed an oxygen sensoe.

Since purchasing my 2002 grand Cherokee ltd in October of 2001 there has been a ticking sound coming from the engine. We first brought the car in on 01/17/2002 to report this and the dealer said they could not reproduce it. On 06/27/2003 we brought it in again - this time the dealer said that the ticking is normal for the purge solinoid valve on the 2002 Jeep grand Cherokee. The ticking is supposedly caused because the housing around the emissions stuff is not insulated. The noise is very irritating and is especially loud in the cooler months. A suggestion was made to turn on the radio - wow - what a solution. I do wonder if this is the real reason or - like the heater/blower - will this fail now that the warranty has expired?.

Engine lost all power, causing multiple near rear end collisions. Diagnostics indicated in Chrysler service manual posted "55" (end of mil codes) indicating no failed components. Service station replaced O2 sensor and cleaned subsequent impacts to fuel injectors. Per Chrysler service manual, O2 sensor failure code "21" should have been indicated for such failures, thus affording a warning to driver of failed component.

We brought the vehicle to lehighton motors in lehighton, PA and they were not able to detect the problm so we were fitted with a black box and were told to drive around and activate the black box when the problem happened. This was a dangerous situation for us. They changed both O2 sensors. The problem persisted, and they decided that the fuel tank sensor package needed replacement. All this cost bout $800. 00 for parts that were in a car with 35,000 miles, and it put us in seriously dangerous circumstances. We contcted daimler/Chrysler for relief, but to no avail. Please investigate this situation.
