A plastic part in the fuel pump is liable to crack under high temperatures. That can lead to fuel escaping from the pump, potentially causing a fire, the Los Angeles Times noted.
The problem affects Pontiac G5 and Chevrolet Cobalt sedans made between 2007 and 2009. Saturn Ion sedans and Chevy Equinox and Pontiac Torrent vehicles from the 2007 model year are also vulnerable to fuel leaks.
GM said it began receiving reports of fuel leaks in 2011. So far, no injuries or vehicle fires have been linked to the defect.
Because the defective part appears to crack under warm-weather conditions, the company is recalling affected vehicles currently registered in California, Arizona, Arkansas, Oklahoma, Texas, Florida and Nevada.
Last week, General Motors announced that has recalled 426,000 Saturn, Chevrolet and Pontiac sedans due to a mechanical defect that could mislead drivers into thinking that their cars were in park when they actually weren’t, leading to rolling vehicles.
Shares of General Motors rose more than 2% in midday trading on Monday.
