Hey, does anyone know what's going on with the 2.4 engines from 2011? I brought the car in complaining that it was running rough, using/smelling oil and getting loud like a diesel. The next thing I know the dealer says the engine cylinders are worn and need new sleeves. After about a few weeks I got it back. They said the engine needed to be rebuilt. So what's going on here? Is there some known issue?

Also, I was driving the family and set my cruise on 75 then turned it on at 70. The engine down shifted and never came out of a lower gear. The tach was at 5000 rpm. I had to take it out of cruise and slow down a bit for it to up shift into OD.

I have 30,000 miles on the nose.

For 2011 non turbo regal owners. GM sent out a notice of possible 2.4 engine issues "chrome layer on the balance chains" ETC and extended the warranty......Mike
