Takata recall my complaint does not stem from the dealership fixing the issue, as I have not brought the truck in yet for the fix. My issues lies in the fact that I have two young children ages 3 and 5 years old. I am now stuck in a lease for 3 years knowing the braking system is unstable. That causes alarming concern to me and my wife. I do not want to drive this car with my children in it and now I have no choice but to so for the remainder of the lease which is almost 3 years as I just leased the vehicle in July. There is no guarantee that this can't happen again and I therefore ask to be able to lease another vehicle at the price I am currently paying per month. The safety of my family is first and foremost. Unless I receive a guarantee from the manufacturer that this will not happen again with my vehicle I am left with more concerns that one who leases a new vehicle should be left with.

I pulled into our carport. It felt like the car just "sped up and went faster and faster." It hit the front of the car straight on. No airbags deployed nor did the front end collision stop happen.

The first time while driving at 60 mph, the vehicle instrument panel warning lights activated and gauges fluctuated followed by acceleration, braking and steering movement. Then the information panel displayed stabilitrak unavailable, collision warning unavailable, lane change alert unavailable and transmission service. The car then started shifting erratically. The 2nd time same situation while driving 30-40 mph.
