2008 Pontiac G5. Consumer writes in regards to ignition recall issues. The consumer stated the original ignition recall was fixed in early November 2014, after the key would not come out of the ignition and the vehicle had to be towed. The consumer experienced another failure on January 20, 2015. It was towed the dealer. The dealer informed the consumer a shifter assembly was needed. However, the part was on national back order.

As I was turning onto the highway, on my way to drop my son off at daycare before work, early March 27th, 2014, my car would not move from the stop sign I was stopped at. It was extremely scary, especially with my young son in the back seat. My car is a manual, and the stick shift would slip into each slot but not engage the gear, which lead me to assume that the transmission had gone out. My car remained running, even with my foot off the clutch, and in any gear, including reverse. I ended up having to push my car off to the side of the road and highway, with my son still inside. Although I felt that this was not the safest situation for my son to be in, I felt that the alternative of remaining immobile in the flow of traffic may get us in a rear-end collision, or having my son standing on the side of the highway while I pushed the car may get him hurt. I was able to get my car towed to my house, but the cost to repair or replace the transmission at a shop is an outrageous price, and I am not able to find a transmission for sale at any auto parts store because it seems that they are no longer able to acquire the part. Most of the mechanics I have spoke with have stated that they have repaired multiple Pontiac G5 transmissions in the recent months. After all the news about GM vehicles, I feel that I may have made a bad investment when purchasing my car brand new and having such a major issue occur this soon. More so, I am concerned by the way my car broke down. It was very dangerous to have my car unexpectedly stop moving as I was turning onto the highway and in the flow of traffic, but all I could think is what I would have done if my transmission had gone out while traveling at high speed or in an area without a place to pull off, it is a scary thought.

I have had acceleration issues several times with the G5. One incident happened while trying to pull onto a busy highway. As I was trying to accelerate to merge the car started jerking almost as if it were out of gas, yet I had a full tank. It has happened many times other than that, but that particular time frightened me and my passengers. I notice it most often while driving and attempting to accelerate to go up hills. When it happens going up hills, it is almost like I lose power. This problem seems to be extremely dangerous in heavy traffic situations. It does not matter how hard or soft you hit the accelerator during this time, it will still do it.
