A heavy-duty clutch assembly for a Jeep SUV is at risk of failing because of a problem with a Pneufram system, according to the company.
The Jeep, a midsize SUV that was delivered in April, suffered a partial failure in the clutch unit and a fire inside the engine compartment, according with the Ohio Department of Transportation.
A state investigation is underway to determine the cause.
Jeep says the problem was caused by an error in the assembly process.
It says it will replace the PneuFram clutch unit, but it could take months or years.
The company says that despite its initial announcement of a full recall, Jeep was already replacing the clutch and engine compartment assemblies at a rate of about 400 a month.
The recall affects about 2.3 million Jeep models sold in the U.S. and Mexico, according a statement from the company released Thursday.
Jeeps also said that more than 100,000 U. S. and Mexican models will have the recall updated.
