I have a 2008 Chevy HHR LT. Started having problem with my key ignition switch last Thursday. Have to turn the key over 4-5 times before my car would start. Once started it drives fine. Then Friday the check engine light came on. Had it checked to find out that my fuel was "lean". This doesn't make any since to me. I bought the car used in May 2012. I haven't had any problems out of it up until now. Could lean fuel be that I got some bad gas? How does the power train warranty work? How long is the warranty?

 

Could be dirty maf. Could also be a faulty evap.

Sounds like you could have a fuel pump going bad.

 

Mrs. Clay- Welcome !! How it works is, if any failed part is on the list, repair is FREE..

Powertrain Warranty is 5 years (from date vehicle was first titled) or 100K miles.
The build date on the drivers door sticker, is NOT the date when first titled.

Electric fuel Pump is covered..

Here's the list of everything covered, I printed mine for my 2008.
