mattw1099 I just experienced the same issue with my 2017 Trax. Happens more often when it is very warm outside.

Minister4Christ I have a 2016 Chevy LT Trax, 4 cylinder. Bought it from Chevy dealer with a little more than 30k Mike on it. It appeared to have acceleration problems from the beginning. After 40k Mike's it started hesitating every now and then, and stalled on my wife once. Took it to dealer they said everything was fine. Seemed to be a little better with new oil, but hesitating returned. Took it to dealer total of six times, still had the same problem. At 60k completely lost power, engine light on, shuttered when you drove. I gave it a complete tune up, new oil, filter, spark plugs and coil pack. It has been running better than when I first bought it. It was really easy to do. The spark plugs were not under warranty, which is why I believe the dealer kept saying there was no problem. If problem returns I will try to repost.

Traxy You may want to check your charge pipe. GM sets parameters where no check engine light will be set. I have major boost leak but still within parameters so no codes. I know my boost system is leaking. Trying to put the finger on where.

Rodney Peterson I have this same problem with my 2015 Trax. I think it's the design to help maintain the great gas mileage these vehicles can get. I have found an engine turner where you might be able to tune this issue out but your gas mileage will suffer.

Latesnoozer My Trax was doing the opposite! The dang thing would miss shift constantly. Instead of down shifting it would up shift to 5th and die! The dealership was no help. I ultimately replaced the battery after, on a whim, checked the charging system and the battery myself with my volt meter. The battery was charging at around 15.3 - 15.6 volts. Not a bad battery.... yet. New battery charges at a happy 14.7 volt and my Trax hasn't had an issue since. The car never acted outwardly in an obvious manner to suggest the battery was bad. It even passed the dealership's physical load test but I worked for a battery store and to save time, if a battery charged over 15.3v in the car we just replaced it because it was just a matter of time before it failed. Caused a bunch of communication issues for the computer during the battery's slow death.

mkimura I have a 2016 Trax that has nothing but issues. The latest is the acceleration issue as you described. They talked the manufacturer and changed the waste control valve. I was also getting a strong sulphur smell at various times.

Flyinfool I tried this on my '18. and could not replicate. I timed acceleration with everything electric turned off that I can turn off. And again with everything turned on that I can turn on. As expected there was a very slight difference with everything on being a tiny bit slower. I would expect this since it does take some of the engines HP to run the AC compressor and the alternator leaving that little bit less power available for the wheels. But the difference is very slight on the watch and is just barely noticeable by my butt dyno. But it is a noticeable difference. Not enough to warrant the effort of turning things off at a stop.

Traxy This should not happen, there's a sensor that detects low voltage and it is suppose to automatically shut down A/C upon acceleration. As far as fan on high speed that is also not normal, at least mine doesn't do that. Maybe you guys just have a weak battery. Even new batteries can be bad.

PM-BGengler I have found, as a "proud" owner of a 2017 Chevy Trax that is does come to accelerate slowly, sometimes incredibly slowly. Do yourself a favor and try it with no A/C and no Fan. Car accelerates as intended, but if one of these are on, let alone at the full power (4 I believe), the car chugs/stalls before taking off at a much slower rate.

And also can be a problem with automatic transmission. I've seen similar messages on Opel Mokka forums, Opel Mokka being the twin brother of the Trax, the automatic transmission is the same(some are made in China).
The same prblem - sudden acceleration or to much acceleration when automatic is changing fom 1-st to the second gear.
If this guy is right and it is electric then the Trax at idle must not be producing enough power to supply the both at full power. Once the car is moving having the air on is not a problem, but I find myself shutting down the air every time I stop on a major road/highway so I can take off instead of stalling.

I've tried everything to see what this issue is, but having the fan on seems to be the most noticeable...

I would be curious to see if anyone else is having this issue as well...

jamie7378 I too have had this issue with my 2016. This occurred on a trip out West and put me in danger several times. At times at a full stop, upon trying to accelerate into or through a intersection the Trax would just set there with little to no response or slowly moving into traffic and then going but nowhere near the expected acceleration. Even on the highway on a grade that was not excessive the car would start slowing well below traffic speed until it would drop 2 or 3 gears and still have no real power. I did take it to a dealership, they couldn't find anything, they asked if any dash lites indicated anything, run a computer diagnosis. And of course I / we could not repeat it and it hasn't done it again. They run some gas and fuel system cleaner through it but could or had no answer for the issue.
