Was driving to san diego, first stop of several on a vacation. Stopped at a stop light. Went to proceed as light turned green, heard a scraping and grinding sound; there was little to no power for the car. It couldn't go above 30 mph, and made a "loud noise" (as stated on paperwork from dealership). Got to city (by the bay) Chevrolet. I ended up spending $1334. 21 for a new catalytic converter and two gaskets. I was also out $111. 26 for a rental as I was going to disneyland and knott's berry farm after a stop to san diego. I had to have the rental from Thursday to Saturday or I would have missed time at disneyland. I picked the day for knott's berry farm. According to Chevrolet, the 2005-2007 Cobalts in nevada (where I bought the car and live) are affected by a catalytic converter issue; however after contacting Chevrolet and advising them of my issue -- they tell me (despite the identical issue) -- my model is not affected. I am looking for $1445. 47 in compensation for actual losses. I would like compensatory damages since Chevrolet is refusing to do the right thing and investigate or reimburse me and it affected my vacation. Also, I want the recall extended to the 2008 models.
