It has taken 10 years for this issue to appear but I knew it would eventually occur. When I looked at the 451 wheel back in 2007 I could see a weak point in the system. I’m sure it’ll soon become a common problem. Smart knew it’d be a problem as they changed the design in 2010.
Disassemble the steering wheel and 1st look at the back of the airbag. There is a small spade connection. This is the less likely cause of the issue. So far, this part hasn’t been the cause but it could be in the future.
