2009 Pontiac G6 Frisco, TX

ENGINE

I purchased a used 2009 Pontiac G6 3.9L almost 4 years ago. I have experienced white smoke pouring from under my hood 3 times so far. I've taken it to the dealership and first time was informed it was a bad power steering hose leaking onto the exhaust- preCat area. The second repair dealership said it was a faulty hose. The third time dealer said it was a bad motor mount. After extensive research online, found out several years of G6 cars have the high pressure power steering hose about 1 inch from the exhaust pipe. This is causing the hose to melt due to the heat. GMC started making heat protective wrap around these hoses which still does not solve the problem-still burns thru. With a simple online search 2006-2010 G6 with the v-6 engines are still having this problem, costing owners money/time and safety issues. When I saw the white smoke, I lost my power stearing, causing panic and difficult steering. GM should have a recall, find a permanent solution where owners/family can feel safer. Most of these cars have low miles considering the age- Are owners afraid to drive the car due to the power steering hoses and exhaust being too close. Causing more concern for safety, and the costs for repairs and tow trucks.

2009 Pontiac G6 Pevely, MO

ENGINE

Taking off to a slow roll without giving it any gas and turning right or left, the steering wheel is extremely difficult to turn. There is absolutely no power steering. It lasts as long until you you give it gas and then the power steering will start working again. While at a steady maintained speed on flat level ground and while at a steady maintained speed going up hill rpm between 2,000-2,500 , the vehicle begins to shake/buck/shudder/stall. Give it some gas and it begins to run smoothly again after about 3 seconds.
