Dear NHTSA: I was very disappointed when my engine developed an oil leak and the cause was due to a known mfg's defect in the plastic oil filter adapter & cooler p/n 68105583-af. The dealer (lansdale Chrysler Jeep, montgomeryville, PA) stated that this part should never fail, it's a known problem with the plastic housing developing a crack, and many thousands of these parts are on backorder because Jeep has changed suppliers. It doesn't help that the part is made of plastic and it's located under the intake manifold resulting in a bill for $977 to replace it. I was lucky as they had a replacement in stock. I've contacted Jeep seeking reimbursement. From a safety perspective, engine damage could result from a loss of oil and a risk of fire if the leaking oil contacts a hot surface. My vehicle has 86,325 miles and is no longer under warranty. Jeep should have a replacement campaign or recall due to the extreme number of failures. I hope you can help with getting Jeep to take ownership of this issue.
I bought this Jeep on the 31st of December. Only 10 days into having it the oil started leaking. I took it to a repair shop and he advised me that it was leaking from the oil filter and housing along with the oil cooler. He advised me that this is a ongoing issue with these Jeeps. This would not be a easy fix as the intake manifold along with the heater hoses, filter housing/oil cooler assembly would all have to be removed.
Chrysler (Jeep) has a long running problem with exhaust manifold bolts breaking prematurely as in my case (75,000 miles). It is a common problem and places the occupants of the vehicle in danger due to exhaust fumes entering the passenger compartment, in addition to extremely hot exhaust gases creating a fire hazard in the engine compartment. Chrysler will not warrant "fasteners" or fix the issue in it's manufacturing plants and leaves the owner with a very large bill to fix it. Can you please research and make Chrysler responsible for continuing to allow a known and dangerous situation to continue? I have called Chrysler and filed a complaint and request for assistance.
While I was idling in a parking lot a coolant hose to my turbo split. This hose ( the size of your thumb) is under the intake manifold and is not accessible to check and maintain. Seeing that this hose is a few inches from the turbo and even closer to the right engine bank, the heat is extreme. The hose is a rubber hose not unlike a lawn mower gas hose. If it wasn't for the smell of hot coolant and being stationary, the engine would of lost it's coolant without any signs. The maintenance portion of the owners manual assumes we can see and get at all coolant hoses. The turbo hose should last longer than the coolant that in it, on mine it was approximately 82,000 miles. A steel braded hose would be more appropriate in this location. Attached is the portion of the owners manual and a picture of the new hose in place. To replace this hose the dealer had to drop the engine out of the truck and it took over 10 weeks to get it back.
The driver pulled the automobile into a driveway on a downhill slope. The driver shut the vehicle off using the push button start/stop. The driver returned to the vehicle 10 minutes later, with a passenger in the front seat. The driver started the vehicle (foot on brake as required) using push button start/stop. The driver engaged the transmission into reverse using the shifting lever (with foot still on brake as is required by the brake transmission shift interlock (btsi) system). When engaged in reverse, the engine revved to a high level, and the car traveled in reverse up the hill (driveway), through the street, and into a ditch. Side and front airbags deployed. Driver believes they never took foot off the brake, and the braking was not sufficient to overcome torque of the engine/transmission. Vehicle damage includes air bag deployment, cabin roof liner detachment, three bent wheels, minor damage to muffler, minor body damage. Dealer checked electronics/instrument recordings and noted nothing unusual appearing, and had no knowledge of similar problems.
