I test drove a 2015 Chevy Trax LTZ yesterday. The mileage is 91k. One owner. I would have bought it on the spot if not for one thing. I stopped at a stop sign. Put my signal on to turn right. The turn was up a hill but not incredibly steep. The car "chugged" or "jerked" and just really would not go faster. Maybe 5-7mph. I was able to get things moving by taking my foot off the gas and trying the acceleration again a couple of times. It didn't start immediately though. This happened again about 20 minutes later. This time I was not at a complete stop. Maybe 10mph and turning left. Car took the turn fine but again, when I tried to accelerate, the chugging started. Maxed out at about 7mph. It felt like it was running out of gas but I had a solid 1/2 tank. Both times, the RPMs seemed to be in the right place and didn't appear to lose power to the radio, air, lights, etc. This specific car DOES have the turbo.

If this is normal, I'd be happy to adjust my driving style lol. I'm currently driving a 2007 Dodge Caliber SXT.

Please let me know if this is something normal, and just part of the turbo or if it something really wrong. I tried to get a video but of course I couldn't make it happen a 3rd time.

Could be the accelerator sensor going bad, or the fuel filter is clogged. Without knowing the cars history of maintenance and physically touching it myself, those would be the first things I would look at.

Thanks! Before I make any commitment to buy, I'm going to have my regular mechanic go over it. I'm going to ask him to check these specific things.

Not normal. Have your mechanic check for codes and maybe the coil pack.

Also at that mileage have him check the PCV regulator for leakage. Not and expensive repair and 13-15 seemed to have this diaphragm go on them.

Hi all,

Just wanted to say I didn't buy the car. I test drove another Trax at a different dealership and did not have this problem. Thank you all for your help.

Having very similar symptom right now. Code coming up is P0132. Going to replace the O2 sensor. Basically, what I think is happening is the O2 sensor is erroneously reporting that the fuel/air mixure is rich and is reducing fuel and the mixture ends up being way too lean and the car can’t rev beyond 3K RPM and lacks power to accelerate.

I recently had this issue. Just as you stated, chugging on light acceleration and up hills. It felt aggressive enough to be a transmission slipping. No codes came on for me unless I pushed it, and even then the code would disappear. I figured it was misfire only by the way it was acting (which is why I was really surprised there wasn't a code going off, the Lord only knows). As soon as I pulled the coil pack it was very obvious what was going wrong. It was probably running on only two cylinders. One plastic shield was completely obliterated and another coil boot was melted and corroded as well. (cylinders 1 and 3). If anybody else has this issue I would highly recommend starting there before getting into vacuum/ boost leaks, or transmission; might save you some time... I attached some pictures. I hope you don't mind the vulgarity, failure at only 85,000miles grinds my gears. Plugs looked good, had to get the corrosion off and added dielectric grease. I did replace them at 60,000 w iridium plugs and I must not have added any.
