I own a 2007 Jeep Liberty limited at any given time while driving the gears seem to slip which causes the slippage light to turn on. I've taken to several Jeep garages and I'm told it's not the Jeep it's the way I drive the Jeep that is causing this slippage of the tires or the transmission. Can you help me with this problem?

The vehicle, when going down my driveway, steep gravel, unlocks the torque converter at around 1400-1500 RPM, allowing the vehicle to 'freewheel', similar to my old 1933 Plymouth. Despite numerous complaints over the past two years, the Chrysler representatives insist that this is normal. Every transmission shop I have consulted, and everyone I know, believes this is not a normal function of the transmission, and in my one million plus miles of driving, I have never encountered it on any other automatic transmission.

Vehicle has 25000 miles and has had four power window regulators break, two of which were the same window. Vehicle transmission also shifts very hard between 1700 and 2100 RPM. Regulators were replaced on warranty, but I fear after warranty expires this will be very expensive. Have had no luck getting transmission fixed, everytime I take it in for repairs, I'm told they can't find anything wrong.

2007 Jeep Liberty with several transmission issues. Consumer states Chrysler never gave a response to his letter and wants the lifetime warranty extended since Chrysler changed it 4 months after he purchased vehicle and a replacement transmission. The consumer stated the dealer reprogrammed the ECU several times, replaced the torque converter twice, replaced the pump, replaced the valve body, cleaned debris out of the pump, serviced the clutch, but the transmission still made a horrible noise periodically. Since the last attempt to fix the problem, the vehicle had a poor throttle response. The consumer also stated it wouldn't creep into gear like a normal automatic transmission; instead it needed significant throttle application to get moving, then it lunged.

My Jeep Liberty jerks between 35-55 mph and 1400-1500 rpms. This has caused the car to slip and slid on icy roads. I first noticed it with only 200 miles on the car. It has been into the shop 7 times for this problem. They have reprogrammed the computer, replaced the fuel pump and the problem is still there. Chrylser said this is normal. I have another Jeep and it does not do this. This is becoming a dangerous problem with the icy conditions where I live.

2007 Liberty developed a shudder in the power train at speeds between 30-45 mph. I have brought the car back to the dealer 5 times in five weeks. They claim it is a new transmission design by Chrysler to get better mileage. I claim it is the worst acting automatic transmission I have ever owned (40yr of driving). The dealer also claims that the transmission is acting the way it was designed to act. Yet, the sales force never mentioned the uniqueness of the new transmission.

My Jeep Liberty sport crd has 16000 miles on it, and since new it has had a shudder or stumble from 50 to 60 mph. It has had repairs to fix the problem, but it still remain to this day. This problem caused my vehicle to loose control in the winter conditions in my area. Which caused my vehicle to end up in the ditch. This could have been much worse if there was traffic at the time.
