1st problem erratic ignition stalling while in park. Battery was replaced and taken to shop, the auto technician assumed based on p0128 p0520 p0441 it was gas fuel cap, switch oil pressure, housing thermostat, gasket intake manifold they replaced O2 sensors vacuum line read a sensor with evapo system causing check engine light came on and a host of other items checked gas cap totaled me $779. Car refuse to started next mornings for pass two weeks every morning several attempts to start car after parked overnight no start only stalling first. Then waited an hour put car in neutral see if car starts it did. After driving that day while driving car acceleration began to go fast by itself on a highway then jerk rpm dropped down while driving my children in the car. I thought maybe gear was out of place so I looked to see if it was in drive, it was in drive. Went back to auto shop they said since car is working now can't hook up system to check p codes because it won't show up if it's working. Told me drive 60 miles to see prob continue. Next morning car didn't start, no fuse signal shows. Then car was dead one click sound ,no stall. Called roadside assist and tried to jump battery. Guy said it's not battery he said it's the fuel pump. Contacted the auto mechanic spoke with mgr of shop and said it can be a tipm and cost $1200. This is a very unstable and unsafe issue my family and I drive in this van don't feel safe 2nd issue car hesitated to stop two months ago when I pressed the brakes to stop car while driving on road to stop at red light, no stop I had to pump brakes and I thought it was brakes I paid for replacement of brakes and pads as well. This electrical module has been the cause of known incidents. It can cause accidents. The van is dangerous safety hazard. Tipm and electrical system is creating unsafe braking and ignition fuel conditions causing malfunction.
