Tl the contact owns a 2011 Jeep Grand Cherokee. While driving at unknown speeds, the contact heard an abnormal ticking noise. Additionally, the contact stated that the vehicle was stuck in the front wheel drive position. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic who stated that the transfer case needed to be replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 60,000.

Transfer case main shaft failed, causing a total lock up of the vehicle. It had to be towed to dealer and took 3 weeks to repair.

The contact owns a 2011 Jeep Grand Cherokee. While driving 10 mph, the four wheel drive failed and caused the vehicle to slide down a hill and crash into a ditch. The service four wheel drive warning light illuminated. There were no injuries and a police report was not filed. The vehicle was taken to the dealer who stated that no repairs were needed. The manufacturer was made aware of the failure. The failure mileage was 49,000.

Vehicle refused to turn over, service 4x4 and engine light on. Brought to dealer replaced fuel pump. Returned to me with service 4x4 and engine light on, slid down on hill no 4 wheel drive. Returned to dealer 4 weeks later transfer case replaced car jump into 4 wheel low while I was on highway almost put me thru windshield. Back at dealer over 1 week the do not know the problem and stated no one on their country wide database has this problem. I was told today that Jeep headquarters wants all reports sent to them to assist repair. I purchased this car used in October and have not driven it more then 1 week. I have a huge payment and huge rental bills I did file a case with Jeep customer but no help.

1. After 2300 original miles on odometer, vehicle developed a vibration in "coast" mode (foot off gas, slack in drive train) between about 45 to 30 mph. Dealership has kept it overnite, test driven it, and contacted Jeep "engineers" about problem, numerous times over the last 4 years. Dealer can't "duplicate" problem, and "engineers are looking for a solution, with less than a handful of reports on 2011 overland's throughout USA". 2. The dealer service rep once said that a dealership mechanic was working on a similar problem with a limited or laredo model. 3. I bought this Jeep new and ordered it with certain options I wanted. I bought it to last me thru my retirement years, being a top rated 4x4. It now has 20,000 miles on it, still has the vibration, and after sporadically checking with the dealership during service or recall work for the past 4 years(!!!!), a solution has not been reached. 4. There's always a "what if" in the back of my mind on what to do in the event I'm at freeway speeds (65-80 mph here) and the drivetrain component (tranny, transfer case, rear axle, drive shaft) that's causing this vibration suddenly disintegrates. 5. Other non-dealership mechanics agree with me on the above listed suspect components based on where I feel the vibration (literally in the seat of my pants).

Transmission shifted into 4 wheel drive (4wd) low, suddenly, accompanied by a clunk and change in vehicle speed from downshifting. Lights came one in the dash indicating loss of traction control and 4wd service needed. This event continued to happen sporadically while driving until we made it back to the dealership. Since downshifting into 4wd low occurred while driving at normal roadway operating speeds (approximately 20-40 mph) it certainly felt like a safety issue, compounded by the fact that traction control was lost as a result. Once back at the dealership, the service department found that the transfer case had an internal failure. The vehicle was in the shop for about 3 weeks and while the transfer case was replaced under warranty. Due to this negative experience with the vehicle we no longer felt safe driving it, and ended up trading it in for another vehicle just a few weeks after getting it back from the shop.
