U.S. security regulators are investigating gasoline pump failures in additional than 600,000 diesel Ram vans that might trigger the engines to stall or lose energy.
The probe covers Ram 2500, 3500, 4500 and 5500 heavy-duty vans with 6.7-litre Cummins turbodiesel engines.
The Nationwide Freeway Visitors Security Administration says in paperwork posted on its web site Monday that it obtained 22 complaints and two subject studies of engines stalling because of high-pressure gasoline pumps failing. Company paperwork say it has no studies of crashes or accidents.
The company says a assessment of the complaints discovered that the engines cease above 25 miles per hour, disabling the vans.
It says that in November of 2019, Fiat Chrysler (now Stellantis), maker of the vans, issued a guaranty bulletin to sellers telling them to gather gasoline pumps on the vans.
The company says it is opening the investigation to learn how typically the issue occurs, what fashions it covers and whether or not there is a security defect. The probe might result in a recall.
Stellantis mentioned Monday in an announcement that it’s cooperating with the probe.
