The 2.4L Tigershark MultiAir 2 has a well-documented pattern of cylinder head cracking, excessive oil consumption (often a quart per 1,000 miles or worse), and stalling under load. A class-action lawsuit was settled covering oil consumption claims for many of these vehicles. Here's how to spot it, what coverage looks like, and which model years are worst.
Excessive oil consumption was settled in a class action. Cylinder head cracks are a separate issue that can still happen out of warranty. 2014-2017 are the worst years across Cherokee, Compass, Renegade, Dart, and 200.
Many Tigersharks burn a quart every 800-1,500 miles. The Stellantis class-action settlement covers diagnostic, monitoring, and in some cases engine repair for affected VINs. Always check the settlement website.
Run free diagnosis →Coolant migrates into the cylinder via a crack near the exhaust seat. White smoke at startup, coolant loss, sometimes a hydrolocked engine. Repair is a head replacement; many owners go to a long block.
Run free diagnosis →Multiple TSBs and recalls address Tigershark stalls in low-speed maneuvers and on grades. Reflashes, throttle body cleans, and PCM updates are the usual fix.
Run free diagnosis →The MultiAir 2 hydraulic actuator (the "brick") on top of the head fails, causing rough running and codes. Replacement is straightforward but parts pricing is steep.
Run free diagnosis →Failed PCV pulls oil into the intake, accelerating consumption complaints and fouling plugs. Often the first thing to address when investigating oil burn.
Run free diagnosis →Slow coolant loss without external leaks is the early warning sign of a cracked head. Combustion gas test to confirm before pulling things apart.

2014-2017 Cherokee KL, Compass MK/MP, Renegade BU, Dart, and Chrysler 200 with the 2.4L Tigershark - the worst years for both oil consumption and head cracking.
2018-2020 saw fewer head crack reports, especially with the 2018 PCM software updates. The 2.0L Hurricane and 1.3L turbo replaced the 2.4 in many applications by 2022 - that pivot speaks for itself.
Out of pocket: head replacement $3,500-$6,000, long block $5,500-$8,500, MultiAir brick $800-$1,500. Always check the class-action settlement portal and your VIN-specific TSBs before paying retail - significant coverage may apply.
If your vehicle is throwing a check engine light, these are the codes most often associated with the problems above. Click any code for full diagnosis steps and typical repair costs.
Stellantis acknowledges over 1 quart per 2,000 miles as abnormal under the settlement. Many real-world Tigersharks burn a quart every 800-1,500 miles.
Coverage depends on VIN, model year, and current mileage. Check the class-action settlement website (search: Chrysler 2.4 Tigershark settlement) and submit your VIN.
Oil burn is gradual loss without coolant involvement. Head cracking causes coolant loss, white smoke, and often a misfire on a single cylinder. Both can happen on the same engine.
Risky. Ring land carbon buildup accelerates as consumption worsens, and a cracked head can hydrolock the engine without warning. Get it diagnosed.
Only with a documented oil consumption test, a pressure/coolant inspection, and a clean settlement record. The asking price should reflect the risk - 2014-2017 examples are routinely $2,000-$4,000 below segment.
