Risk: If the air bags do not deploy as intended, it can increase the risk of injury.

Fix: MBUSA will notify owners, and dealers will update the air bag control unit software, free of charge. The recall began November 2, 2018. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2018100008.

Estimated cost — typical U.S. ranges

Dealer

~$935–$1175

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Dealer

~$285–$390

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165
