The recall affects trucks, cars and SUVs in the 2014 - 2017 model years.

This recall does not concern Takata airbags, which have so far been linked to 13 deaths and more than 100 injuries worldwide. Takata airbags use a chemical that can degrade over time, especially in warm and humid conditions, and explode in a hail of hot metal shrapnel. More than 24 million vehicles and 28 million Takata airbag systems have been recalled so far, and in May, a report surfaced that the National Highway Traffic Safety Administration would recall 35 million more.

In July, Reuters reported that GM would have to recall 4.3 million Takata airbag systems at a cost of $550 million for the company. While today's news appears to be a separate issue, the number of affected vehicles remains the same. GM says today's recall will not impact its financial results in any large way.
