I had engine light on, VDC light on and cruse control light on for my car 2007 Tribeca B9. When the car is cool is driving fine but after a few hours my car starts and 150 miles starts to sake and I cannot accelerate. I have to stop to cool down and then I can drive another 5 to 10 miles and is doing the same thing. I took it to a Subaru service and they cannot figure out the problem. They read the codes from memory PO175, PO172, PO137, PO157 and they tell me that I have to bring the car when it starts doing it otherwise they cannot fix it. Please help!

The variable dynamic control (VDC) is very delicate and even harder to diagnose. But if you have all of them codes they should have a place to start. Dealerships have a hotline directly to SOA (subaru of america) tech support and if they place a call to them they will walk them through it. Sounds like you may need to find a different dealer service dept.
