GM recalls 3.2 million US cars

General Motors is recalling 3.2 million more cars in the U.S. because of ignition switch problems.

The company said it will change or replace the keys on the cars from the 2000 to 2014 model years.

GM says the switches can unexpectedly move out of the “run” position if the cars are jarred, such as by going over railroad tracks or a pothole. That can shut off the engines and disable power steering.

The recall is part of a GM review of ignition switches after the company recalled 2.6 million older small cars earlier this year for a similar problem.

GM also is recalling 166,000 other cars for a series of problems.

And the company raised its expected second-quarter charge for recall expenses to $700 million.
