I just got the 2009 Pontiac Vibe because its a toyota and I could use my GM card rebate. That being said, I didnt realize the 1.8L was a brand new engine. I thought it was just a revamped version of the previous 8-10 years. I was excited about getting a car with the tried and true 1.8L which gets the best mpg of any toyota engine, which is not exactly the case with the new engine. Im not sweating it (5 yr/100k warranty if GM still exists), but are there any problems associated with the new 1.8L? I think the corollas have had them for the past year or so. How is the mpg (only have 600 miles so far)?
