Vehicle stalls when driving. 2003 Jeep Liberty sport/freedom. When driving, car felt like it was tightening, check engine light came on, rpm dial started spinning like crazy, and the car completely shut down. Towed to mechanic, told code registered cam shaft sensor. Replaced! picked up vehicle, drove 4 miles, shut down again. If vehicle sits and cools off, it will restart. Drove back to mechanic, he replaced cam shaft sensor - thinking it was defective. Next morning, on way to work, stalled while driving again. So, three days in a row, same problem. Very dangerous!!!!!!. This time code registered computer problems, and he suggested I take to dealer, as code part was covered under federal emissions warranty. Took to dealer on Friday, October 22 - 8 days now (also need to do recall work, apparently that's not high on a dealer's list) and he said he can't get it to stall, and his code is registering a transmission issue. I know I'm a 'girl', but it doesn't make sense that the car would completely shut down if the transmission had gear problems. The car completely shuts down! wondering why no recall - seems like other Jeep owners have similar problems (reading threads on internet). I think dealer may be trying to save costs, because I told him I no longer feel safe in the vehicle and may trade or sell. He said part is $875, but can't guarantee that is problem, he has to clear all the codes 1st. How does he know the computer isn't kicking out faulty codes at this point? I say this because when we replaced the crank shaft sensor, the computer said it was still bad, although it was a brand new part. And, the mechanic did not get the code the dealer is getting now. Seems like Jeep has a problem, but no solution. Btw, my 7 year/70,000 mile warranty apparently expired on may 24, 2010.

Failure Date: 12/22/2005

March 2005 - 2003 Jeep Liberty 4 cylinder - carriage town Chrysler, delaware, ohio - I took my Jeep Liberty to the dealership for backfiring, check engine light, running rough. They found only spark plug #1 fouled and replaced only the spark plug. 2nd time approx a week later I took my Jeep Liberty in and it was running rough, no check engine light. Dealership refused to look at my vehicle without the check engine light on. 2 days later I returned vehicle with check engine light on, running rough, and backfiring. They replaced all spark plugs and all wires. This happened at approx 28,000 mile on the vehicle. December 2005, engine light on, running rough. Replaced spark plug #1 only and wire on spark plug #1. I had been told by service department at this time they had put a "special" spark plug in my vehicle and that there was a technical service bulletin on my vehicle. Jan, 2006 - vehicle is currently in the shop and they are trying to determine what is wrong with the engine, currently they cannot find what is burning up spark plug #1. Technical service bulletin: mfg bulletin number: 0803403 mfg bulletin date: 20040302 component: electrical system details: new spark plug for 2. 4l engine.

car   Check Engine Light On problem 6
Failure Date: 08/09/2005

The contact owns a 2003 Jeep Liberty. The crank sensor failed. The contact has seen other similar complaints on the internet. When the crank sensor fails the vehicle will stall and cut off, causing a loss of steering and brake power. For instance one can be going 60 mph and the vehicle will just stop. There is no warning or lights to warn him. The crank sensor failed and vehicle will stop. Check engine light came on afterwards but it automatically reset I self, causing the check engine light to go off in thirty minutes. This was the first time this happened. But while attempting to take the vehicle to a service station it happened several times. The dealership replaced the crank sensor and the cam sensor. . He has found on the internet the codes that gave a false reading for the cam sensor going out instead of the crank sensor.

car   Check Engine Light On problem 7
Failure Date: 06/12/2004

Transmission and engine lights came on upon towing a coleman "yuma" pop-up camper. Took in to dealer and dealer found that torque converter to be bad along with gear wear. Transmission needed to be replaced and gear wear repaired. Car has only 8,000 miles on it and it is the first time the car has towed anything. The car should not have had a problem since it is rated with a much higher towing capacity than the coleman "yuma" is. The dealership is trying to tell me that this is an isolated incident of a bad transmission, but upon further investigation with Jeep forums on the net, 85% of Liberty owners are experiencing problems with their transmission after 8,000 miles! one owner has had his transmission replaced 3 times! the dealership said this was covered under my warranty this time, but that it would not be covered next time. If the transmission is faulty on all of them, I don't want to get stuck with a lemon on a brand new vehicle!.
