A Chrysler oil consumption lawsuit alleges these Chrysler, Dodge, Fiat and Jeep vehicles stall while driving because the 2.4L Tigershark engines have piston rings that don't work properly with the cylinders.
Fiat-Chrysler has been accused of calling the 2.4L Tigershark engine's agressive oil consumption "normal" in order to avoid having to recall millions of vehicles.
A new lawsuit says a defect in that engine's piston rings allows oil to enter the combustion chamber. That leads to roughly a quart of oil burning off every 1,000 miles. If an owner follows the recommended 4,000 mile oil change interval, it puts them at extreme risk of permanently damaging the engine.…keep reading article "Lawsuit Says a Piston Ring Defect Burns Through Oil in the Tigershark Engine"
Had problem with engine stall while braking and cornering. Checked oil levels and was over a quart low. Checked oil again just over a week later and was down another quart. Took it to the dealership and had them check oil consumption. I was told that a quart of oil every 850 miles is ok for this model. This is stupid, why would I ever do an oil change, by the time I get to 3000 miles I have pretty much replaced the oil.
Within 16,000 miles our Jeep has burned 6 quarts of oil. In the last 5,000 miles it has gone through 2 quarts of oil. Today it is at the dealership where I was told this is 100% normal. The service advisers immediate told me that GM's burn much more oil and began a rant telling me everyone has this issue.
Oil consumption is ridiculous. Told by dealership that the 2.4L is supposed to burn 1 quart every 2000 miles because it runs hot. Again, this is ridiculous. If I go on a trip across the country, I have to put a case of oil in the back of my brand new vehicle. 11,000 miles now and went through 4 quarts at my expense. No warning given.
My wife's Cherokee has been for some time shutting down on her unexpectedly without any check engine lights or any warnings. At our dealer they informed her that the oil level was very low, close to 2 quarts of oil in the engine when it is supposed to maintain [closer to] 6 quarts. The part that they couldn't answer was why was the vehicle not alerting us of low oil levels.
