WASHINGTON — Chrysler LLC is asking nearly 500,000 customers to return vehicles for repairs of safety defects.
Notices are to go out in November to owners of about 102,000 Dodge Avengers and Chrysler Sebrings with 2.4-liter engines built for the 2007-08 model years. Repairs are aimed at preventing engine compartment fires.
The automaker told federal regulators that engine coolant can get into a radiator cooling fan motor connector, and arcing can occur. The company said it was aware of 17 fires as of Oct. 2.
Dealers will install a wiring harness overlay and, if necessary, replace the fan motor, the company told the National Highway Traffic Safety Administration.
In a separate action, Chrysler is recalling about 72,000 2008-model Avenger sedans and Sebring convertibles to install retainers on front door latch cables.
Nearly 300,000 Jeeps and Dodge Nitros should have their antilock brake control units reprogrammed to prevent momentary delays in brake function, the automaker told owners. Affected vehicles are 2007 Jeep Wranglers and Dodge Nitros and 2006-07 Jeep Grand Cherokees and Commanders.
The company said it knows of one crash, with no injuries, that may be related to the problem. No injuries were reported.
The problem tends to occur when a vehicle has been going up a grade and the driver switches from the accelerator to the brake pedal, as in preparing for a turn, company spokesman Max Gates said.
Separately, about 29,000 Jeep Grand Cherokee and Commander SUVs built for the 2007-08 model years will get new front brake calipers. The originals were made with the wrong grade of iron and could break, NHTSA said.
Also, dealers are to replace front drive shafts in about 1,500 Dodge Ram pickups with two-wheel drive and manual transmissions built for 2007. The drive shaft yoke may break.
And about 1,200 Dodge Avengers with all-wheel drive built for 2008 are to get new fuel tank retention straps. The originals may break, NHTSA said.
