Oil Consumption Defect Causes the 2.4L Tigershark Engine to Stall
A serious defect in the 2.4L Tigershark engine causes an excessive amount of oil to be burned during normal operation. Owners must constantly top off the oil and have consumption tests run at the dealership, or risk the engine seizing up and stalling out while driving down the road. A class-action lawsuit wants a nationwide recall.
Fiat-Chrysler (FCA) has been accused of knowing about the problem since 2015 but telling owners the consumption levels are "normal" to avoid a recall.
According to the owner's manual the oil should be changed at 4,000 miles (6,500 km) under normal driving conditions. Even under severe Operating Conditions the manual says the oil message will illuminate as early as 3,500 miles since the last reset.
But owners say the engine consumer a quart every 1,000 miles. So if you follow the recommended interval, you'll cause irreversible damage to the engine.
The plaintiffs say that by continuing to call the consumption levels "normal," FCA has avoided the tremendous cost of doing the right thing by recalling millions of affected vehicles.Instead, they've left owners to pickup the tab.
This problem has been reported by owners of the following generations. While there's no guarantee it affects all the listed model years, most years within a generation share the same parts, manufacturing processes, and problems.
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.
