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!!!!!????

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

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!

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....

Car engine would cut off while slowing down or at stop sign/light. Check engine light came on & had to pay for a full diagnosis to find out the coil pack needed to be replaced...then it was followed by needed a replacement of a catalytic converter...then the ignition recall followed by a replacement of the Starter. What a crappy vehicle :(

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.

Was driving to doctors appointment and car started to hesitate and check engine light was blinking, barely made it to doctor, upon returning to my home did it again, I took it right to my mechanic. He diagnosed the problem as bad ignition coil and spark plugs. Over $200 to repair. This should be a recall. I was afraid for my life...

Has not been fixed cannot afford it right now. Initially car was stalling, rough idle, surging & initially MAP & MAF sensors replaced, new air filter just in case & throttle body cleaned. Now check engine light is just flashing,stalling immediately, black smoke from exhaust, now misfiring & engine shaking. Don't know when it will be further repaired.

I have had multiple parts replaced,,TCM, Coil Pack, pollution thing. the list goes on. Now it is Coding misfire in number one and running extremely rough I am once again putting it in the garage on Monday to have the Camshaft pos sensor. I feel Chevy saw me coming. I have called and complained and like many others have been told that their is nothing they can do. They definitely don't care where their paychecks and their beachfront properties come from.

The coil pack was bad and was making the cylinders misfire. Gasoline got into the catalytic converter and was combusting in there witch then melted my O2 sensor and then my air intake sensor went bad.

Randomly started stalling then shifting from 3rd to 4th I hit about 4000 rpms. Sounded like I blew the engine up. Later listened to it. Heard no clicking. Oil was fine. Assuming it's the coil.
estimate for ignition coil, ignition module, and a tuneup with 4 spark plugs and a bootkit plus 2 hours labor = $870.

Engine stuttering on start up, idling and worse in wet weather. Service shop diagnosed as needing replacement ignition module, boots and spark plugs. May also need to replace oxygen sensor.
