While travelling on the interstate at approx 70 mph, the vehicle lost torque and lost ability to accelerate and had a loud knocking noise while hitting gas pedal. Vehicle is only 80,100 of 100,000/5 year powertrain warranty. Dealer would not warranty this powertrain issue even though the VIN has multiple earlier powertrain warranty items completed. Dealer diagnosed as front transfer case internally failed, and front drive shaft has failed. My independent mechanic indicated this failure is common and may also require a front differential replacement. The dealer initially diagnosed as front differential failure but determined it to be the transfer case. Parts are not readily available due to this being a common failure (4+ weeks for parts). A font drive shaft and transfer case failures are very dangerous and can cause the vehicle to crash.
Just recently bought the car with 50,000 miles on it car is in good condition but only a month after I purchased it a light saying � service 4wd� has popped up on my dash and ive taken it to several dealers and they say its needs a new transfer case and is a common problem with these cars. If it is a common problem then why has there not been a recall on it, it is pretty ridiculous as much as people pay for a car and the problems that go wrong with it and the manufacturer cant even fix there own problems on the cars that built! there should be a recall for this problem as it is not a cheap fix and is obviously a problem with the manufacturing when the car was built. I am disgusted with how shitty and unreliable cars are now a days, something needs to be done!.
An unintentional shifting of the transfer case the 4 wheel drive its on and cant take it off, all started with the vehicle been stationary.
Driving from the gas station to the highway when the rear air suspension failed to shut off and overinflated causing the forward mounts on the rear subframe to be ripped out of the body of the car which cause the subframe to crash into the exhaust, transfer case, and drive shaft which immobilized the vehicle. No injuries occurred luckily as the vehicle had not made it to the highway when the failure occurred.
