There are no known fires or injuries from this problem.
Fiat Chrysler Automobiles will recall a total of 34,633 examples of the 2016 Dodge Durango and 2016 Jeep Grand Cherokee for a potential fuel leak. Only vehicles with the 3.6-liter V6 are part of this action. The campaign specifically includes 30,180 of them in the United States, 2,534 in Canada, 489 in Mexico, and 1,427 outside the NAFTA region. FCA U.S. believes as few as 30 vehicles might actually have the problem, but it needs dealers to inspect them all to be sure.
During assembly at the Saltillo Engine Plant in Mexico, there may have been damage to the fuel rail crossover tube for these V6 powerplants. Long-term thermal cycling, fuel exposure, and pressure pulsations can cause a fuel leak to develop. In a worst case scenario, this issue could lead to a fire.
The automaker discovered the issue during an inspection when an FCA employee noticed a fuel leak on a single vehicle. A further investigation of uninstalled engines found 21 with damaged parts out of 20,158 units inspected. The company eventually found that there was an assembly error from “inadvertent contact between a manifold fastener and the fuel rail” for an 11-week period in the first quarter of 2016 that caused damage to some powerplants.
FCA U.S. is not aware of any field reports of people reporting this problem, and the company has no warranty claims about it, either. There are also no known injuries.
Dealers will inspect the SUVs for damage to the fuel rail crossover tube. If harmed, technicians will replace the fuel rail assembly and the lower intake manifold. The recall will begin December 19, 2016, according to the National Highway Traffic Safety Administration.
Jeep last needed to recall some of its recent products in October when there was an issue with the impact sensor on the 182,308 examples 2016 and 2017 Wrangler. There were no known complaints about that problem, either.
