problem #6

Jul 152010


  • 23,000 miles


Vehicle was driven to work, approx. 15 miles, and parked. When attempting to start the vehicle to go to lunch, the clutch pedal snapped and dangled. The clutch hydraulic unit actuating rod had snapped in two. The vehicle had to be towed to the dealer for repairs. The replacement part have to be ordered and the vehicle will not be repaired until next week. I have requested the dealer to keep the old part for me. If this had occurred while driving in the morning or lunch time traffic I have no doubt it would have caused a serious accident.

Wrangler 6-cyl

  • Manual transmission
  • 53,000 miles
The contact owns a 2006 Jeep Wrangler. The contact stated that the front suspension would bounce and cause rough handling of the vehicle, more so in colder temperatures. The failure occurred while driving 12 mph. The dealer took the vehicle for a test drive but could not duplicate the failure. He did state that the throttle body could have caused the failure. The failure mileage was 53,000 and the current mileage was 57,000. Updated 5/3/10 the consumer was also having problem with the transmisson. The dealer informed the consumer not to use first gear, but to start in second gear. Updated 06/28/10

First I started to have a loud rattling sound when I am idling, neutral with the clutch out. I was told it was normal wear noise, but I could replace the throw out bearing to make it quieter. After it was replaced I started hearing a loud whistling sound when my Jeep is coasting and above 2000 rpms with the clutch out. The dealership keeps telling me it's normal. I have taken it back 2 times, but they can't find the problem. I'm still having the noise and there is no sign of a fix from the dealership. They just keep saying it's normal. Just like everything else they have had to fix!!!

Wrangler 4WD 6-cyl

  • Manual transmission
  • 500 miles


After approximately 500 miles the vehicle began to exhibit difficulty in shifting from first to second gear. Problem is very apparent when the vehicle is cold, but still noticeable after the vehicle warms up. When shifting from first to second, it feels as if second gear is not fully synchronized. If it is done at a normal shift rate it actually clips second gear (and makes an associated clipping/grinding noise). Pausing in neutral and resting the shifter against second, you can actually feel two or three gear teeth go by before it will drop into gear. To get it to shift smoothly without clipping gear teeth requires a long enough delay in neutral that following traffic almost rear ends the vehicle. The driver is essentially faced with the decision of damaging the transmission or risking getting rear ended. Double clutching the vehicle helps, but obviously should not be required for a fully synchronized transmission. Took the vehicle into the dealer at 1164 miles and 1306 miles, but the service technicians claim they cannot reproduce the problem, but they adjusted and lubricated the linkage as a preventive measure. However, the service manager and another dealer employee who drove the vehicle have noticed that second gear doesn't feel the same as other Wrangler with manual transmissions. I have also had several other people drive the vehicle and they agree that the transmission isn't shifting correctly. I am scheduled to take the vehicle in again for this problem, but via phone the dealer doesn't appear to have an identified cause or fix. Vehicle is now at approximately 1600 miles and problem is still very apparent, if not worse. This issue appears to be related to ODI id number : 10156374 & 10160948.

Wrangler 4WD 6-cyl

  • Manual transmission
  • 50 miles
Three month old Jeep Wrangler with 6 speed. After vehicle has been sitting for a few hours, regardless of outside temperature, the first several 1-2 shifts upon driving it again exhibit a loud grinding sound which can also be felt through the shifter. The transmission is reluctant to come out of first gear. It has to be pulled out of gear instead of just sliding out. It then feels like it bounces off of second gear, requiring another attempt to engage second. When I first got the vehicle, it actually felt like there was no fluid in the transmission. Shifting becomes much smoother, I.e. normal, once it has been run for a few miles, although I do feel it occasionally even after driving for a while. Dealer road tested the vehicle and says it is "O.K. at this time." This condition may have some safety ramifications in addition to the transmission longevity issues. First gear in this vehicle is very low. I only use it to start rolling a little bit and then quickly try to engage second. However, I am so conscious of the difficulty of this 1-2 shift that I execute it very slowly, all the while cringing at he thought of the damage I am doing to the transmission. The problem is that the RPM's drop off so much during the time of this shift that there is little power available once I actually engage second, resulting in leisurely acceleration at best. On two occasions already, the people behind me have blown their horns and nearly run up my back because, I believe, they must have thought I was going to stop instead of continuing to accelerate. It is getting to the point where, if the road is level, I take off using second gear instead of first until I have traveled several miles and the transmission begins to behave normally. I have driven manual transmissions for 20 years and have never experienced this type of behavior.

Wrangler 4WD 6-cyl

  • Manual transmission
  • 60 miles
New Jeep Wrangler with 6-speed manual transmission grinds when operator upshifts from 1st to 2nd gears, necessitating an unusually slow shift and consequent poor low-speed acceleration from a stop. Condition is worse when vehicle is cold and intermittent when warm. Took vehicle to dealership for warranty repairs. Jeep representatives state condition is "normal" for this vehicle. No repair performed.
