(AP) Federal safety regulators are investigating 2009 and 2010 Ram pickup trucks and the 2012 Jeep Grand Cherokee SUV for safety problems. The National Highway Traffic Safety Administration says the rear wheels can lock up on the pickup trucks, causing drivers to lose control. On Grand Cherokees, a hose carrying power steering fluid can leak onto the engine, causing fires.
The investigations affect up to 230,000 Ram pickups and nearly 107,000 Grand Cherokees. The pickup is Chrysler's top-selling vehicle, while the Grand Cherokee is No. 2. NHTSA investigators could make the company recall the vehicles, although no recalls have been required yet. Chrysler says it's cooperating with the government and takes customer complaints seriously.
