General Motors announced three recalls on Friday that included 474,000 vehicles worldwide, most of which are top-selling vehicles with potentially flawed software.

The biggest of the three recalls affects around 467,000 Chevrolet Silverado and GMC Sierra pickups equipped with four-wheel drive, as well as GMC Yukon and Chevrolet Tahoe and Suburban SUVs, the Associated Press reported. The Sierra is GM's top-selling model. 

The best-selling pickups and SUVs have a software glitch that can put the transmission into neutral, causing the vehicle to turn off while driving or roll away if it's parked. For the recall, dealers will recalibrate the software.

No crashes or injuries have been reported in connection with the issue, according to the automaker. Most of the affected vehicles were sold in the U.S. and Canada.

The other two recalls announced Friday affected a smaller number of vehicles, one including 4,800 Chevrolet SS and Caprice police cars with faulty windshield wiper modules. The modules, which have teeth that can become stripped and result in failing wipers, will be inspected by dealers to be replaced if needed.

For the third repair, 2014 model year Chevrolet Corvettes with the FE1 or FE3 suspensions will need to be inspected for flaws in two rear shock absorbers due to an insufficient weld. This recall affects about 2,000 vehicles. 

GM's latest recalls bring the automaker's total for this year to 48 recalls and more than 20 million vehicles, almost doubling its 2004 record of 10.75 million cars and trucks. 

The Michigan-based automaker has had a troubled year following the recall of 2.6 million small cars connected with at least 54 crashes and 13 deaths. GM, which has already agreed to pay a $35 million federal fine for delaying repairs on the vehicles for nearly a decade, is still under criminal investigation from the Justice Department.
