Two of the Chrysler's top selling models are facing a US government investigation for safety problems after accidents were reported in the country.

The popular Jeep Grand Cherokee and Ram 1500 models will be investigated over concerns that it might put passengers at risk. The rear wheel of Ram pickup can lock up from the 2009 and 2010 model years and might cause accidents. On the other hand, power steering fluid hoses can leak in the 2012 Grand Cherokees model, possibly causing engine fires, according to documents from the National Highway Traffic Safety Administration.

The investigations will cover a total of 230,000 Ram pickup and nearly 107,000 Grand Cherokee units. The Ram pickup is the company's highest selling vehicle this year, while the Grand Cherokee is at the second position. The company might have to recall vehicles if the investigations require such a move, however, the authorities have not asked for any recall yet.

The company has said that it is cooperating with the National Highway Traffic Safety Administration and it takes customer complaints very seriously. The government agency said that it opened investigations after receiving several complaints from the customers.

Chrysler spokesman Eric Mayne has asked any customers who are facing any concerns with the models to visit company dealers.
