Excessive Oil Consumption on 2017 Jeep Cherokee 2.4L Tigershark - TSB or Recall?

0

Vehicle: 2017 Jeep Cherokee Latitude 2.4L

I own a 2017 Jeep Cherokee Latitude with the 2.4L Tigershark engine, and it seems to be burning through oil at an alarming rate. I'm having to add a quart every 1,500-2,000 miles, and the low oil warning light comes on regularly. It's got about 85,000 miles on it.

I've heard about issues with these engines and excessive oil consumption. Is there a specific TSB or even a recall for this problem? What are my options here? I'm worried about engine damage and the long-term reliability of the vehicle.

Has anyone successfully had this addressed by Jeep, especially outside of the original powertrain warranty? Any advice on how to approach the dealer or what to expect would be greatly appreciated.

Excessive oil consumption in the 2.4L Tigershark engine, particularly in 2015-2017 models, is a well-documented issue. You're not alone in experiencing this. Here's what you need to know:

  1. Known Issue & TSBs: Yes, there are multiple Technical Service Bulletins (TSBs) related to excessive oil consumption for the 2.4L Tigershark engine. TSB 09-001-19 REV. A (and earlier versions) specifically addresses this, often recommending a software update to the Powertrain Control Module (PCM) to revise the oil consumption monitoring strategy and, in some cases, replacement of the PCV valve or even the piston rings.
  2. Oil Consumption Test: The first step a dealer will typically perform is an official oil consumption test. This involves topping off the oil, sealing the dipstick/fill cap, and having you return after a specified mileage (e.g., 1,000-1,500 miles) to measure the consumption. This is crucial for warranty claims or goodwill assistance.
  3. Causes: The primary cause is often related to the piston rings and their ability to properly scrape oil from the cylinder walls, leading to oil burning. The software update aims to improve combustion and reduce carbon buildup that can exacerbate the issue.
  4. Warranty & Goodwill: While your 2017 model is likely outside the standard 5-year/60,000-mile powertrain warranty, some owners have had success pursuing 'goodwill' repairs from FCA (now Stellantis) due to the widespread nature of the problem. This often requires a documented history of oil consumption tests and maintenance.

When to See a Shop:

  • Immediately: Schedule an appointment with a Jeep dealership. Explain the excessive oil consumption and specifically ask about the TSBs related to the 2.4L Tigershark engine. Request an official oil consumption test. Be prepared to provide your maintenance records. If a Check Engine Light illuminates, especially with codes like P0520 (Engine Oil Pressure Sensor/Switch Circuit) or misfire codes (P030X), it indicates potential engine damage from low oil or related issues, and immediate attention is required. Ignoring this can lead to catastrophic engine failure.
