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.
