Car speeds up without pressing the gas petal and it's hard to stop it when in motion on interstate it stopped out of nowhere and turned off with an 18 wheeler behind me like to have killed me got car in neutral finally forcefully praying that jesus protect me because it would not shift into gear and pulled over to side of road. I'm scared to drive my car. Driving down road steering wheel locks up causes engine to shake whole car and backfires my car rides really rough. Messed up power steering has caused my blinkers not to work now. I'm really sad. The engine light comes on every time I put gas in my car. The transmission acts up and when driving my car it's like it doesn't know what gear it should be in so it jerks really bad.

On the26th of June 2018 I was leaving work when all if a sudden when I started it up there was bad knocking coming from engine when increasing RPM's. I took it to mechanic and requested my oil to be changed and to check why it was knocking. At that point I was told there was metal shavings in the old oil as well as filter. I was shown this by the mechanic. He stated berrings were going and I would have to rebuild or replace the engine. Confirmed by another mechanic. Upon returning home about 30 min later I noticed fresh oil under my car. I took it back and was shown a major oil leak at the timing chain cover. Turns out the bolt came loose. He tightened and oil stopped leaking. This was probably the cause of bearings going out. This was a sudden issue and not over a period of time. The car has 45K original miles on it. How can this be? 10 years old but only 45K miles.

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.
