What 2014 Mercedes-Benz AMG CLA45 owners say
Air bags
On 12/26/19 contacted Benz dealer in west caldwell, nj. Explained to rep. That there was a recall on my vehicle for faulty airbags that when they are deployed had metal and could cause harm or death to passengers. The rep indicated that they do not know when my airbags would be replaced. She put in a call to service dept. So me and my family, including grandchildren have to ride around in a very unsafe vehicle and the Benz dealer seem as though they just don't care. They should be made to give you another safe SUV to use until the one you have is fixed. This is a horrific situation. I want to stop payment, due to the situation.
Still waiting from November 2017 to now February 2018. No replacement no notice no nothing. Please help

I purchased my vehicle early March from Carmax. They offer a 90 day guarantee on anything that will go wrong with the vehicle full coverage.
