My vehicle was stationary at a red light waiting to turn left on a city street in park, as I tried shifting gears back to drive the car jerked forward very intensely ' which it has done multiple times before' . Before reaching the drive position. It then proceeded forward out of my control into the back of a truck linking my front bumper to the hinge on the back of the truck.. In the midst of that I immediately tried shifting into reverse but doing so was very difficult has the car kept pressing forward into the back of the truck, so I put the car in park then back to reverse when it finally shifted into the reverse gear vigorously which then abled be to detach from the truck. I pulled to the nearest parking lot to check the damage, and seen multiple leaks not sure where from.

Takata recall, I have a 2007 pontiac g6 base model. It has 110,756 miles and it breaking down badly. The gear shift, transmission and steering wheel control all started to mess up around the same time. My friends father had the same exact car a few years ago and said that they have a transmission problem and to call the dealership and/or the manufacturer to find a solution to my problem.

Vehicle has been sitting since the first of february due to a constant coolant leak. Leak first appeared at bottom corner passenger side of radiator, and within a week had also showed up on bottom corner driver side of radiator. Eventually wound up replacing the overflow reservoir, 3/4" hose tee located directly under overflow, several clamps, transmission cooling lines, installed brand new radiator and oil pressure switch located directly above oil filter. After 10 days with absolutely no leaks, they reappeared in exactly the same locations. Finally traced leak on passenger side to upper corner passenger side of intake manifold gasket, and the driver side leak traces to almost directly at the coolant crossover pipe gasket. Now, I'm again facing another $200 payout to the parts store.! I'm going to make this repair myself, as I have made all repairs for the previous 6 months. My 07 g6 was wonderful for the first 3 years of ownership, but the last 3 years have become nothing more than an absolute nightmare. If I could file for reimbursement for my expenses during this time I have absolutely no doubt that with the prices of parts, current hourly rate charge set at $75-$100 hour, and reimbursement for time spent wasting time going to pick up parts the total would most likely come out to $8000-$9500. I can't even afford to pay for another vehicle, and sadly I also can't afford to continue investing in a vehicle that has become a mechanical monstrosity with an extremely voracious appetite for parts and money.

Water pump - continuous replacement of water pump about every 2 to 2-1/2 years (after original has quit working) along with thermostat replacement. This process is extremely time consuming and onerous to complete within a typical 8 hour day, along with a fluid drain, flush and replacement with fresh fluid. Also, constant regular replacement of both front hub assemblies, though not quite as time consuming, is still a burdensome issue. Especially as neither the individual front hub assemblies or the water pump is inexpensive. The 3 front hub assemblies - 2 for the front left since april of 2016 & soon to be 2 right front hub assemblies since march of 2016 (both of which locked up or "froze up" therefore not allowing the wheel to turn at all. Both instances of the water pump failure could have resulted in very serious engine damage and/or failure had the problem not been diagnosed promptly. I can ill afford to continue replacement of either part at current prices every couple of years, never mind the inconvenience and loss of usually both class time and availability for work. Problems began march 21, 2013 and continue through today, as I am still assessing how to afford a second much needed hub assembly for the right front of my vehicle. This, along with at least another $500 (minimum) for other parts needed to complete current mechanical issues and needs, is difficult to afford. Especially when all parts that are included in the previous mentioned amount are most definitely necessary to insure the safety of occupants and others who may be around should one or more parts fail while vehicle is in motion.
