The shifter includes a feature called autostick that allows you to manually shift the gears. The autostick is too sensitive, and if bumped will down shift to first gear causing a sudden reduction in speed. I was driving down the road at roughly 50 mph when a person in the passenger seat gently nudged the gear selector to the left, which shifted the car into 1st gear. To recover the car has to be put into neutral than put back into drive.

Since the Jeep was new, it has made a noise similar to "spark knock" or pre-ignition coming from the area of the engine compartment. The noise did go away after a few minutes, however it now persists even after the engine has warmed up. The noise is more noticeable in cold weather. The Jeep dealer has tried to locate the source to no avail. A Jeep technician even came out to our home for an early morning test ride and he heard the noise. He checked for loose cables etc. But the noise continues. This is very frustrating as I have this feeling that the answer will be found about the time the Jeep is "out of warranty".

The automatic transmission - tiptronic shift - is much too sensitive, down shifting. The transmission is an automatic with a manual -tiptronic- capability. There is no adjustment linkage. My dealer has order and replaced the original unit, but there is no difference. The pull distance of the lever to down shift is less than 1/16th inch. Conversely, the push distance of the lever to up shift is approximately 3/4 inch.

My 2012 Wrangler sport (6sp) has a faulty transmission. It makes a horrible rattle at high rpms in 3rd and 4th gear, the gears whine and 1st is really hard to engage when the vehicle is slowly rolling. Sometimes I have to double clutch it just to get 1st gear to work when rolling. Reverse grinds. The gear shifter shakes excessively when vehicle is in 4th and 5th gear. Shifting from 1st to 2nd is notchy as is 5th to 6th and when putting it into reverse. The clutch often has a crunchy feel when I press the pedal to the floor.

This is the second time that the transmission has downshifted-went from drive to 2nd.or 3rd gear range. Vehicle has automatic transmission. Vehicle was started and began driving. Slowed down at stop sign and began to pull out vehicle went from "D" range to 2nd on indicator. Vehicle has select shift + and -. each time I thought I had touched selector.

The transmission became difficult to engage 1st gear. Shifting into all others was very notchy. Finally, in traffic, it became impossible to engage 1st gear at all. The vehicle had to be started in 2nd gear. The vehicle had limped in to the dealer. Upon inspection it was found that the 1st gear synchro had cracked and failed. This can create a hazardous situation in busy traffic. This transmission has been reported by various user forums as faulty and prone to failure, including popping out of gear and difficult shifting. Popping out of gear in a busy intersection could be dangerous, especially if you are unable to engage another gear. The dealer is repairing the broken synchro.

Auto shifter just barely gets bumped and vehicle downshifts.

- Marietta, OH, USA

This vehicle has auto stick shifting with an automatic transmission. For upshifts movement all the way to the right, hitting the end of travel is required the make a shift up in gear selection. On down shifts, just touching the shift handle and barely applying pressure activates a downshift. No movement of the shift handle is required. This way to sensitive.

- San Ramon, CA, USA

Automatic transmission with 'electronic range select' allows a downshift with a move of the shift lever to the left when in 'd' drive. A move to the right up-shifts. Accidental downshifts occur frequently because of 'hair-trigger' nature of shift lever controls. The slightest, barely perceptible movement left causes a downshift, often unintended and unexpected. Up-shifting requires a definite movement to the right. Discussion of this issue with 2012 automatic Wrangler drivers on Jeep internet forums suggests a number of people experience and have a problem with this, while a number of drivers state their shifter requires a definite move left to downshift. I experience frequent, accidental downshifts on every trip due to this defect. Current mileage on this vehicle is 1100 miles. Sudden deceleration due to accidental downshifts can cause loss of traction on unpaved, gravel, icy or snowy roads, confusion, disorienting, and over-revving the engine.
