general problems of the 2006 Chevrolet Impala

First battery needed replaced every year then few weeks ago with no warning light or messages that battery was dieing the battery died again it was replaced then it started reving up and down on its own while driving so it goes faster then slower on its own when it feels like it. . Tps wont show tire pressure cant relearn tire positions now dash lights works usually then don't bright lights don't work now if automatic light control is on car shakes bad while breaking idles hard uses alot of gas now massive amount of heat coming off engine now with no dash light or guage saying temp is going up engine smells kind of bad after driving the car replaced transmission once couple years ago transmission maybe going out again the gear shift locks don't work it slips out of gear and into another gear effortlessly while driving and while parked without pressing the button to move the gear shift clicking or tapping noise started coming from front end only when turning left now does it while. Turning and sometimes while. Going straight and it's all still happening. . . Theres more but not going into all of it now. Dtc code listed 2days ago was listed b1000-00 electronic control unit. Searched google for code and got posts saying ecu needs replaced. . Updated or reprogrammed and some say bcu needs replaced. . Upgraded or reprogrammed. Each time I search the code I get a different reason for the code and different meaning. I have a 2006 chevy Impala ss 5. 3l v8 with police package. Car is available for inspection anytime.

The Chevrolet Impala I own has had major problems about a month after I bought the car. . . . The whole electrical area in the front has went haywire on me. . . . I cannot signal, or turn my bright lights on at any time. . . . Plus, it will not start for me when I need it to, I always have to get a jump from someone, & that even takes between 10-20 minutes. . . . The place that I bought it from, the repairmen cannot fix it right for me, it is not fair to pay all this money for my car, which will not work right. . . I have not been able to use my signals for a very long time now, it is very, very frustrating to me. . . . I have been stranded on the streets, the highway, even at work after my shift, it has even stopped on me while taking my kids to & from school. . . .

Car hard to steer and turn, hit a concrete barrier damage the left front bumper, light, body frame on left side of the car.

The electrical in the car is messed up. I turn to the right and my radio shuts off, also if its dark out and my lights are on and I put the windows down the lights down as I'm pressing the button to put them down.
