2015 Chevrolet Trax engine problems

Filed Nov 29, 2025 · Engine · CA

While driving in the highway vehicle lost power and gray smoke came out off the exhaust, it was hard to accelerate and TCS warning light and check engine light popped up. TCS warning light extinguished but check engine light still on. Cars behind me could have hit me from behind, because it was a sudden loss of speed, it made other drivers switch lanes creating the risk of crashing others or myself. I have taken the car to a mechanics and some say it’s the turbo and others say they don’t know what it can be and can’t really help me.

I have had multiple engine problems with my trax. For starters, shortly after I bought it in 2021 I had to have the radiator replaced, then in Aug or Sept 2022 I had to have the coil pack replaced, the in Oct 2022 the turbo needed to be replaced. Exactly 1 year after replacing the turbo, I had to replace it again in Oct 2023. Now I'm being told that these cars are having problems with Piston rings going out. After repleacing the turbo once again, my car was still acting up. I took it back to the mechanic and they told me my piston rings are shot. Due to this issue, I now need a new motor. I've been told by 3 different Automotive shops that they have replaced several engine in the past 5 months due to the Piston rings and turbo going out in them. My car is a sitting duck. I'm highly mad. To add full to the fire, some of my features are not working due to an electrical issue.

I have recently heard what could best be described as a squealing sound. I could also smell fuel inside the vehicle while driving. I thought it was oil that had leaked onto the serpentine belt and had it replaced but the noise continued. Listening closer I realized it was coming from the area around the intake manifold. Searching online I found several YouTube videos and comments from people mentioning loose spark plugs caused their issue. Checking mine I found that two of the four spark plugs were loose enough to not require a wrench to remove them. Tightening them eliminated the noise. I have owned this vehicle since it was brand new and have never asked a mechanic to check or replace spark plugs, nor have I done it myself. I did recently replace the intake manifold, which required removing and reinstalling the ignition coil. I feel like loose spark plugs represent a fire hazard as it allow the fuel to blow past the cylinders and into the engine compartment.

When I’m driving I started to hear the gear shifter sound like it’s moving inbetween drive or maybe out of drive I’m not really sure. Then after that happens when I stop driving and turn the car off the car won’t release the key from the ignition. I have to wait for it to lock itself into park and then the key will release.

P0299 indicates problem with turbo charger compromised boost power, - injector control pressure sensor - EGR - MAP - Accelerator pedal Input I have to pay a expensive diagnostic from the dealer to find out the issue, it’s too expensive to do that now after Covid-19 money is scarce.
