Had to replace all ignition coils at around 56,000 miles into driving my Chevy spark.
Around 45,000 miles the traction control light began turning on at start up. The engine light did not turn on till ~55,000 miles for this problem. At that point, I noticed not only would the traction control light turn on occasionally during start up, but there was a significant loss of power when accelerating. I had to be careful when making turns onto oncoming traffic at times because of the increased chance of causing an accident because of not being able to maintain traffic speed.
When taken to an AutoZone to read the computer codes, it gave codes for misfiring and codes pointing to issues with a sensor in the exhaust or the catalytic converter. I first replaced all the spark plugs and drove it for a while to see if it fixed the problem. It did not. I then replaced all the ignition coils and the engine light immediately went off and I have not had the traction control light come on anymore since then.
I am currently at ~76,000miles now. So I have driven ~20,000 miles now with out anymore problems, so far, I believe it was faulty ignition coils causing these problems (I've had this car since it was brand new, 0 miles).
I also posted about having to replace the coolant reservoir at ~50,000miles.
