Manifold/header/muffler/tail Pipe problems of the 2008 Chevrolet Malibu

Intake manifold gaskets leaking bad, loss of steering at low speeds causing for manuel strength and transmission wouldn't change gears at 85,000 miles within the 1st I purchased the car.

While driving 50 mph down the highway in my 2008 chevy Malibu (106,800 miles) the traction control light came on and information center read "engine power deduced" and my car slowed to 20 mph almost immediately with no warning to me or the vehicles behind me. Luckily there was a wide shoulder and I veered off to avoid being rear ended as I had my 3 child all in car seats in back. I called the dealership but as they weren't open yet, I did what I had to as one of my children is a special needs child and was almost time for his seizure medication and drove the car on to my mother in laws 4 miles away. I drove down the shoulder of the highway for approximately 1 mile to make it to my mother in laws turn then the next 3 miles to her house was less congested with traffic luckily. The car had a slight shake to it almost and something seemed like it was rattling almost under the hood but a slow rattle not like a knocking sound tho. After the dealership opened I took the car to them after shutting off and restarting car ran normal again. They said they could find the issue in the history. Chevy told us the cam shaft solenoid had internal failure and needed replaced. We got it fixed and changed spark plugs and did a small tune up to make sure that was the whole issue solved. Last night just a day later the same thing happened as my husband was driving the car. This is an issue with many newer chevy cars some still with just 50,000 miles on them. It is a major safety concern and needs to be addressed with gm in a recall I am afraid before more lives are taken due to faulty engineering and parts! please look into this further! chevy also found a crack in the exhaust manifold that they are replacing for free already as well as multiple other recalls we are awaiting parts for.

The exhaust manifold of the 2008 has a severe crack which allows exhaust fumes into the cabin of the vehicle. I cannot keep the fan on while the vehicle is stopped, idling, or in slow traffic as the fumes are so strong that it causes headaches and nausea. The vehicle was taken to two different Chevrolet dealerships to pinpoint the source of the exhaust fumes and nothing could be found. Afterwards, it took my husband less than 10 minutes to locate and photograph the exhaust leak on the exhaust manifold. Two other close friends also have 2008 Malibu's and both of their cars have the same dangerous issue of exhaust fumes leaking into the cabin. One has had this replaced at Chevrolet dealership with oem parts at a cost of $1500 with the explanation of the high cost for the repair being that the exhaust manifold is connected to the catalytic converter and the whole unit had to be replaced. One year after this expensive repair, her exhaust manifold has cracked again. Another friend got a quote of $1300 but cannot afford the repair. I cannot afford this repair either and it baffles me that Chevrolet will issue a service bulletin to replace my chrome wheel covers but when I called to ask about the well known issue of cracked exhaust manifolds, told me that they hadn't heard anything about the issue and simply passed me off to a local dealership to make a repair appointment. This is a dangerous situation and one that is common and well documented with a quick internet search on exhaust cracks on Chevrolet Malibu's and cobalt's in the 2007-2009 years. Given the dangerous nature, the high cost of the repair that many cannot afford, and the common occurrence of the problem, Chevrolet should issue a recall to address this issue.
