When pushed to speed up at a fast rate and upon approaching 65mph or faster the service engine light flashes slowly. My mechanic found the code reader saying a misfire was happening. When that light flashes it starts to shake pretty bad. Determined that cylinder 1 has low compression. Only way to find out for sure what to do next is to tear down the motor which I do not have the money for that. Sad how waistful people are forced to be with vehicles. Its still pretty new!! We took good care of this jeep maintaining it correctly since we got it with only 37k miles and has not had any problems till now. So this was a shock! Before 37k miles I am not aware of this particular jeep's engine repair history. Also this same jeep had the clogged fuel line causing the tank to spill out while fueling up when it was not full yet.

Vehicle started exhibiting a cyl #3 misfire showing code p0303 and all the signs included in tsb 09-007-06. Was also diagnosed by the dealer and having defective cylinder valves and valve locks. I have contacted chrysler about this problem and they refuse to accept any responsibility for this even though they have a service bulletin out about it. This issue is causing the vehicle to produce more emissions and waste more gas while it runs incorrectly also causing premature damage to the catalytic converter. Any help the federal safety agency can provide to help rectify this matter would be great help as jeep wants to hide from all of there defective parts behind new owner fiat.

Several things 2 list: vehicle = 2.8l diesel jeep liberty, 2006. The codes are p0093 & u0121. 1st) it says a large leak in the fuel system. Something in the emission system. Has happened several x's. I've had it towed 4 this. Engine runs rough & quits @ x's. No power. Changed fuel filter & did air leak test in the fuel return system / tech at dodge jeep dealer. No air in return line found. Problem still exist on an intermitant & sporadic x frame since june 2010. Last x occurred = 8-20-10ish. 2) low boost from hole in the waste gate actuator vacum tube from improper routing at factory. Found by tech at jeep dealer. 2 visits many hours & $$$. Egr valve replaced @ same time. Big $'s. 3rd) belt squeak from bearing going out in A/C compressor /dealer tech??? 3rd visit. Need A/C compressor he says. Previously changed tensioner pulley for this problem but did not fix problem. They now say its the A/C compressor??? 4th) right rear electric window motor failed 10-2-10. Replaced motor/regulator assembly 10-7-10= $172.99. I should be reimbursed for all parts & labor for these damages. I paid a lot of $ for a supposedly good vehicle but it keeps failing. 5th) part time 4x4 light on dash says its in part time 4x4 when in two wheel drive. Haven't repaired cause of $. Please note that because of low power I was almost in several accidents because of the low turbo boost at acceleration. There could be injuries or fatalities in the future if this happens to someone else that's not mechanically inclined and not aware of reduced engine performance of a turbo failing slowly like mine because of a small hole in the waste gate actuator tubing from vibration on the housing bracket by the tube. Was replaced and rerouted by dealer tech.
