Fiat Chrysler planning for a major recall on engine used in Jeeps

Detroit — Fiat Chrysler Automobiles is preparing for a possible recall related to an issue affecting upward of 1 million vehicles, likely including Jeep SUV models, equipped with its 2.4-liter Tigershark engine.

The expected recall is related to emissions testing conducted on the gasoline engine and, according to the company, is not connected to claims summed up in various lawsuits that the engines burn excessive amounts of oil, which could cause stalling. It’s not known how soon the recall could happen.

“In connection with internal testing, we determined that approximately 1 million vehicles equipped with the 2.4L Tigershark engine may have excess tailpipe emissions,” FCA said in a recent regulatory filing.

The extent of pollution from the Tigershark emissions was not clear. FCA said it has been in contact with the U.S. Environmental Protection Agency and California Air Resources Board about the situation.

“FCA has been working closely with EPA and CARB, and we continue to do so, on a group of vehicles equipped with Tigershark engines. As this population ages, some vehicles exceed in-use emission requirements, depending on drive cycle and mileage. We are conducting test programs to define a remedy, which also requires approval by the agencies. Affected customers will be advised when service becomes available, and will be provided free of charge. This is not a safety issue and there are no enforcement actions,” according to a company statement provided by spokesman Eric Mayne.

The EPA, through spokesperson Enesta Jones, responded to an email from the Detroit Free Press by saying that FCA is doing a voluntary recall based on in-use testing done by EPA.
