The National Highway Traffic Safety Administration has closed its investigation into problems with stalling in Chrysler 300C, Dodge Charger and Dodge Magnum vehicles from the 2006 model year.
NHTSA received 300 complaints of the vehicles stalling, mainly when the vehicle is stopped or traveling at a low speed. Chrysler has agreed to provide a lifetime warranty on the 19-gallon fuel tanks. The original warranty was for 3 years or 36,000 miles.
Chrysler determined that when using high-ethanol fuels, a shutoff float in the fuel tank could swell in an open position, allowing the vehicle to be overfilled and causing fuel to enter a purge line. This can cause the engine to stall after refueling.
The company will be offering reimbursement to some owners, whose vehicles experienced this problem in the past and needed to be repaired.
The problem involves 154,000 vehicles and includes cars with 5.7- and 6.1-liter eight-cylinder Hemi engines.
NHTSA determined that the problem was a low risk and has been addressed through the extended warranty offered by Chrysler.
