Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The clips that hold the transmission shift linkage have completely snapped. This is a known issue in 4 cyl models and should be extended to 6 cyl models. My car will not go in to park. It will not start. You can actually open the engine compartment and see that the linkage has play. This is incredibly dangerous. I'm thankful we live in a flat area. This is completely unacceptable and someone will end up hurt or dead because of it.”
NHTSA complaint #10958837, filed 2017-03, 163,000 miles“Car started dragging - could not drive no more than 5 miles - transmission went out - would not go in reverse - no indication on computer of engine problem - read about similar recall on Pontiac G6 for transmission problems - this incident happened around the same time recall put out on certain G6 - but not mine because of engine size - I do not understand why my vehicle did not fall under this recall - I spent a lot of money to replace it.....updated 10-27-15”
NHTSA complaint #10763488, filed 2015-09, 72,000 miles“Headlights going out. Poor connection, burning/melted headlight socket, headlight choose when they want to work. Actions taken, I didn't wait for a recall. Burnt socket lead me to believe the harness wasn't able to withstand the amperage. I replaced the wires running to headlights with a larger gauge. Replaced the headlight connector. All has been well since, going on 3 years now. Another wiring issue is the injector/can sensor harness. If this becomes loose in any way the car runs very rough, poor fuel, low idle, or stalling. …”
NHTSA complaint #11080675, filed 2018-03, 166,000 miles“When you are driving either one headlight will go out and then come back on. Then the opposite headlight will go out and then comeback on. Then sometimes both headlights will go out at the same time. I've had people flash their lights at me thinking I am high beaming them when one of my headlights turn back on. I also had a spun bearing in the bottom end of the engine which caused the vehicle to stall while turning at an intersection and almost got rear ended. I also had my vehicle stall for no reason at all. …”
NHTSA complaint #10607081, filed 2014-06, 20,000 miles“In early may my 2009 Pontiac G6 shut off unexpectedly while reversing in a parking spot. I tested the car in drive also and realized the ignition could be switched off while in gear. I have tried to get GM to repair the faulty ignition but since it has not yet been added to their growing list of recalls, they wont even look at it without leaving the car for a $150 inspection. This is absurd since the part should take 30 minutes to install and costs them next to nothing. I'm sure there are many other vehicles not under the recall that also have the issue. …”
