Additional recalls announced today by General Motors are expanding beyond the ignition switch defects that have plagued the company for the better part of the year. The automaker is recalling more than 822,000 cars worldwide for a variety of issues. Potential problems include defects with seats, air bags, turn signals, improperly welded parts, and power steering failures. The six new recalls bring GM’s total for the year to 60, covering over 29 million vehicles worldwide.

Some of the cars in the latest recall have already been flagged for other defects. The 2014 Chevrolet Impala has now been recalled three times. The first, in February, was due to a defective transmission shift cable adjuster, which would allow the car to roll after being parked. In June, it was recalled again. Ignition switch failures were shutting down the engines and on-board electronics at speed, causing the air bags to fail. G.M. recalled more than 65,000 Impalas on Wednesday for an additional defect in the power steering.

The company also recalled more than 475,000 cars, including models of the Chevrolet Camaro and Equinox, GMC Terrain, Buick Regal and LaCrosse, and the Cadillac SRX. This recall is to correct a defect that allows the front and passenger seats to move up and down freely because of a loose bolt. These new announcements are in addition to previous recalls, which have included Chevrolet Cobalts, Saturn Ions and other small cars.

For most of 2014, G.M. has faced an uphill battle created by the vehicle safety crisis linked to defective ignition switches in millions of older cars. The company did not disclose these problems to regulators or the public for more than a decade. But as recalls begin to affect newer models, there could be a significant cost to the automaker beyond making the fixes.

“These recalls will have a significant impact to General Motors’ bottom line,” said Eric Ibara, director of residual values for Kelley Blue Book, “and ultimately the market will judge.”
