My Pontiac G6 2008 started having acceleration problems. When getting onto the highway the car takes a long time to get up to the 55-65mph speed. I researched this problem on Pontiac G6 forums and many people are having the same problem. The car shouldn't be having this problem so early on. This is a dangerous defect as people are already flying on the highway and when getting behind a car that is taking a long time to get up the matching speed, you are asking for an accident. I've already had people honking their horn at me. This car has serious issues outside of the steering problem reported. Between constant water leaks, actuators failing too early on, speakers blowing out when hardly used, and now this engine issue, I will never get a GM car ever again. For a car that only has 60K on it, these problems should not be happening. This is stuff a 100K+ mile car should have. Poorly designed car that every Pontiac G6 owner is aware of, and now the us government.

My car was involved in the safety recall 12106. I found this information out via internet prior to the recall taking affect by GM. I took my car into the service dept after being stranded for several hours and having my car towed they stated it was just a bad battery and never even looked at the transmission cable and released my car to my father who is not the legal owner, never even spoke to me. The next day I was stranded again with my small children for a couple of hours in the cold. Had my car towed again to the service dept where they finally looked at the transmission cable. Argued with me that my car was not involved in the recall although I knew it was. I paid for it to be fixed $467.41. They released my vehicle to me several days later as they didn't have anyone for a few days to look at the car. Released the first time unfixed and unsafe and not even to the legal owner which is a huge liability. I took my car to les swab and paid over $100 for a new battery that wasn't needed only to be stranded again the very next day. When we took my car in the first time we told them what was wrong due to the recall I found online and they never even looked at the transmission cable per the service manager. This whole process took about a week and a half. They did provide me a rental car for 3 days which they covered. This was a very stressful situation and no one believed me that there was a recall. Recalls should really be put out asap as I happened to have this issue prior to the release date of the recall. I have filed a complaint with the BBB and have been told I should consult with a lawyer for releasing my car unfixed, unsafe and not to the legal owner. I should be compensated for my time, stress and their lack of responsibility for releasing my vehicle unsafe.
