Ecotec Gen I was re–engineered to be smoother and more efficient than its predecessor. Featuring an dual in–block balance shafts, power–steering pump, water–pump housing, and removable oil filter housing. This engine replaced the Quad–4 and GM 122 in North America and first appeared. GM offers an official kit which can be converted into 2.2 supercharged versions using modified ECM software. Model L42 is an CNG version of the Ecotec 2.2, producing 129 hp and 129 ft⋅lb. This LSJ was listed as one of Ward's 10 Best Engines in 2006! Sealed transmissions elude fluid access to function like regular transmission systems without requiring fluid changes for maintenance. A sealed transmission has fill and inspection plugs, with the inspection plug removing excess fluid and the fill plug adding fluid. Nobody told me during my tenure in ‘shop class!’ Knorr’s Automotive wants $55Ø to fix an exhaust leak, which is their disastrous mishandling. This situation is only going to get marked by more confusion & errors. Vehicle fires are rare and small leaks in fuel tanks or lines can ignite, in defective vehicles during crashes.

I had 2 kids in the car,the accelerator pedal stuck,car kept speeding up.. I was using both feet on brake & er brake as well!! I was swerving in & out of traffic,running red lights & praying for our lives,we got up to 85 miles per hour in a 35mph zone!! The car was revving out of control & black smoke was coming out from under the hood! I managed to slam it into park & we all jumped out & ran,very frightening & almost ended in a collision. The intake manifold gasket cracked at 1yr old and 10,000 miles,the tires needed resealing at 5000 miles. Ridiculous!!
Coolant leaked into engine caused problems, wouldn't start half the time, couldn't fill up without gas pump cutting off constantly (took 20 minutes to fill up). Took car to dealer and other shops spent tons of money problem not solved. Got so feed up with this car I pulled the tags and bought a honda. It is really unfair how the manufacturer of this car was allowed to get away with putting out such an inferior product. There should have been a major recall on any number of these problems. I was never notified of any recalls or the class action law suit.
