The National Highway Traffic Safety Administration notified Chrysler Group LLC that it has begun a preliminary investigation into more than 100,000 2012 Jeep Grand Cherokees and 230,000 Ram 1500 pickups model year 2009 and 2010.

NHTSA notified Chrysler last week that it was beginning the investigation into the Grand Cherokees after receiving two complaints that the engines caught fire. According to one complaint, the driver noticed power steering fluid leaking onto the ground shortly before the engine caught fire. Jeep agreed to replace the vehicle for the owner. No one was reportedly hurt.

"Both complaints were received within the last month and allege severe fires resulting in total vehicle loss with the cause as yet undetermined," one NHTSA report read.

The Ram 1500 investigation involves a dozen complaints about problems with the rear differential failing and causing the rear wheels to lock up. Out of the 12 complaints, one involved an accident, though no injuries were reported.

Chrysler was notified of the investigation on July 19.

"Chrysler Group takes seriously every customer complaint and is cooperating fully with NHTSA's investigation," said Chrysler spokesman Eric Mayne.

A preliminary investigation is opened to see if there are more vehicles with similar problems. Ultimately, it could lead to a recall, but nothing has been determined yet.

The Ram and Grand Cherokee are the two best selling vehicles for Chrysler, which has seen sales climb 28.6 percent this year.

Meanwhile a much bigger potential problem looms over Chrysler as NHTSA investigates more than 5 million Jeep Cherokees, Liberties and Grand Cherokees, going as far back as 1993 model year. NHTSA is attempting to determine whether the gas tank is dangerously placed behind the rear axle resulting in fires after rear end collisions.

That investigation began in 2010.

      I have a 2011 ram 1500 the rear differential had to be adapted with a plate that would through oil at the differential to keep it from locking up and I also had a noise in the front differential I changed the oil my self and found the oil was 1 quart short being it only holds 1.5 quarts I was concerned and the differential rebuilt. Also the transmission had a noise problem in eco mode the torch converter had to be replaced. But I will tell you this Dodge cares about quality before any work took place engineering at Dodge would not let a mechanic touch my truck until they where totally involved as to what work would take place, I am so happy with my truck now, no funny noises, If you are not happy with the dealer go direct to Dodge they truly want the truck perfect and go out of there way to make sure it is repaired properly I will never get rid of this truck and I never have said that about any vehicle I have ever owned.

      Not just Chrysler, but Ford Escape's, GM Chevy Cruze and Express/Savanna vans, BMW's, and even the newest Ferrari, have all caught fire.
