Owner reports
Selected complaints filed with NHTSA by 2006 Pontiac G6 owners, lightly cleaned up (personal details are redacted by NHTSA).
Power steering warning on radio, never once did a warning light on dash come up. This started at about 193,000 miles. Turning over car constantly to get my power steering to start. About a month after it just went out while driving approximately 40 mph. Kept pulling over to restart car, never turned back on. Potential wreck trying to turn to get into work parking lot when the car wouldn't turn. Dealerships claim my car was fixed already years ago, however this problem with the steering started again apparently at about 193,000 miles. The steering wheel started jerking and shaking when the car was idle around the same time the power steering message came across the radio. The car would also randomly lock my horn, didn't realize it could do that until I couldn't honk when someone was merging into me.
The electronic stability control has failed, due to sway bar links are worn out and causing wheels to vigorously wobble causing the Eps input circuit to shut down the system to avoid overloading the circuit and burning up the module , I believe the recall hasn't been fixed , Can you please consider the issue as dangerous and repair my car ... I am not trying to say this but I am homeless and dependent on the car for shelter as well as transportation... Please note don't use last statement to show sympathy on me ... I am doing ok today, Thank you, have a blessed day
I have had to get 3 new keys made for this car due to the security light coming on, sometimes it will not crank or start, so I have replaced the starter twice, have replaced relays and fuses, and the security light will come on while drive down the road and all gauges drop to zero, even the gas light says empty and every light on the dash comes on. But the car will still drive. But once you turn it off it will not start for a few hours! It's impossible to find parts for Pontiac anymore so everything has to be ordered! This should've been recalled a long time ago!
My car stopped working all of a sudden in the middle of the road. no warning signs were made nor any of my lights came on. it's rough running and never stays on long to drive. when i brake it completely shuts off. it overheats without the temperature gauge telling me it is. i don't know exactly what is wrong but it's not working now. i couldn't go over 35 mph without it shutting off either.
While driving I'm going around a corner and the steering was grabbing and getting tight I had to mussel the car home then it stopped doing it the again and again now my steering has not power steering and when I back up it grabs sometimes out of my hands and almost breaks my arm. This car is a death trap. There were no warnings till it happened
When I go to pull into a parking spot or leave a parking lot I sometimes (often) hear a dinging sound then all of the sudden I lose power steering to where I almost hit the cars around me. There has been the same make, model and year of my car that has had a previous recall for electric power steering assist (eps) in the past
