airbag lights flicker ABS lights and all others inside

All the electrical lights inside the car flicker. As do all my Dodge Avengers. It is a faulty electrical system along with faulty tipm modules. I have 4 Dodge Avengers from 3 2012's and 1 2014. Every single one of them have a knocking under the dash which has not been fixed. And all of them have had problems with tipm modules. The airbags are killing people and I think this is just a fault that they knew about but still sold the cars without fixing the problems. They need to fix these problems, me as a american did not buy a car to get killed in nor to fix and spend money where is unnecessary for someone else to make a profit on mistakes and lives of others. Stop this madness and I for one want to press charges!
