Car stalled, restarted, no power and kept stalling. Dealer did so-called "diagnostics" and said I needed new spark plugs, thermostat replaced and fuel induction service, cost $769. Took to an independent mechanic, changed plugs because I told them dealer said needed done. Problem persisted. Independent investigated further and found the problem. Cost $290

The engine light would come on and go off all the time. Went in to get it fixed after Autozone guy thought if could be spark plugs but turned out to be engine coil. Just picked it up after getting fixed. You know with all the recalls and crap wrong with this car, I no wonder they quit making them. I am so ready to buy a Ford. This car is CRAP!!!!!!! What's worse is I gave up a perfectly never worked on Chevy Cavalier for this newer car. WHAT WAS I THINKING!!!!!????

My car did the same as all the others, stalled and misfired when slowing down and coming to a stop the first indication was that my head lights would dim and my car would have much less power then the stalling would begin, my check engine light never came on and the incidents seem to happen more frequently when it was colder outside but not always, my car definitely does not get the gas mileage that it should and seems to run with less power. Had my manifold cleaned out as they believed that it was clogged this improved the situation slightly as far as the stalling goes but I still have a car that is running powerless with crappy gas mileage and seems to be eating up oil but no leaks? Very dissapointed!

I was told that I needed to have my engine rebuilt and the ECM rplaced. The car is still having electrical problems. Told I needed the TCM replaced, and still have the problems with the electrical system.

The car wanted to stall while breaking for stops. I had a tune up one day. The same day it still wanted to stall after the tune up. Had it at BP their machine said it needed a mass air flow sensor. Same thing...wanted to stall. Went bk to BP then their machine said the lower mass air flow sensor...had it changed...same thing...wanted to stall...had the fuel filter changed...omg same thing...now the mechanic says it could be the coil pack...they're checking for one for a decent price....
