2019 Chevrolet Trax Engine Problems

See attached document for complaint.

At roughly 90,000 miles, the turboboost charger went out in this vehicle and needed to be replaced. After speaking with my mechanic and other Chevy owners, it is a common issue in these vehicles, with many needing to be replaced well before the 90,000 mile mark that I hit.

One of the first things I've noticed about my car is in the summer, when it's at least 75 degrees, my transmission will hesitate while speeding up. In march of 2024, my check engine light came on, i brought it into chevy and they said i needed a new turbo, so i asked them about a loaner car in the meantime while it gets fixed, they said no. they were on backorder for my turbo. So they told me to keep driving it while the part gets delivered. I did that. Eventually my turbo came in, brought my car in, they took it, put a new turbo in. When I went to get my car, I test drove it on the highway, speeding up slowly, and while doing that, I blew my engine. I lugged it back by going 20 mph back to the shop, luckily it was just off the highway. I brought it back and told them something happened, they checked it out and let me know that my engine, exhaust and all the needed components are broken. They finally decided to give me a loaner car, although I did have to fight for it a little bit at the end of my car getting finished, they wanted me to pay $1200. I refused as them having me drive my car while its broken is not a good idea and not my fault that it blew. I argued my side and got it down to $600. the next month on the 16th, i stopped to get gas and when i left the gas station, while speeding up, my car comes to an almost dead stop, so i pull it over, all lights on dash flashing, and car will not turn over. got it towed and they changed battery. a year later, my check engine light comes on again, I scan the code, it's the turbo. But it goes away. In January my temp sensor went out and my car said it was overheating as I was driving on the highway with no dash lights. 13th of february, my engine light came on while on my way home. I brought it to a local small shop Where they told me I need a new turbo again.

This 2019 Chevrolet Trax has had the same dangerous and expensive problem twice: In 2022, when the car had just over 35,000 miles, it started to lose acceleration, especially at highway speeds, slowing it to a dangerously slow pace in traffic. At a later time, the check engine light came on. Culver City Chevrolet replaced the turbo charger under warranty. In late January and early February, 2026, after only about 25,000 miles of use since the repair, the car exhibited similar failure to accelerate on the highway and in local traffic and the check engine light came on. It requires a new turbocharger again at a cost of approximately $3,500. The 2019 Chevrolet Trax is not trustworthy for safety with this recurring issue.

Started my car and it made a noise that didnt sound good. Took it to Van Chevrolet and they said it was my turbo. My car is under 100,000 miles, 2019, and giving the code that should qualify it on the recall list. They are trying to charge me 4000 to fix and have not given a rental which is about to make me lose everything.

Bought 6/17/2023 with 81k miles (1.4L turbo). By ~7/1/2023 it ran rough and hesitated after refueling. Firestone (Brick, NJ, 7/5/2023 at 82,090 miles) said radiator leaking; keep topping off; noted open Chevy “special coverage” bulletin. Over ~2 years kept adding coolant (high consumption). Rough running worsened. Lester Glenn Chevy (Toms River, NJ, 10/20/2025 at 122,815 miles) replaced the evaporative emissions purge valve under special coverage N212338400; fixed post-refuel roughness but not overall rough running. Regular oil changes; last 10/1/2025 at 121,872 miles. Codes then: P0171, P0299, P0300, P0442, P0449, P0496. On 11/27/2025, at ~60 mph uphill on the Garden State Parkway, engine shook, dash showed “Engine Power Reduced/Service StabiliTrak” (CEL blinking), lost acceleration. Pulled over and towed; white smoke at tailpipe. Tow driver suspected coolant ingestion/head-gasket failure needing engine replacement. Odometer: 124,180. Traded in on 11/29/2025 at Automotive Avenues (Wall, NJ); no manufacturer/police/insurance inspection.

Engine light with P0299 code: Turbocharger/Supercharger Underboost. Car had hard time accelerating, especially going up the hills. Turbocharge By-Pass Valve replaced at a service center. Engine light came on again 2 weeks later when getting onto the freeway, attempting to accelerate to 70 mph. Same p0299 code. No prior concerns or symptoms, the car is under 89,000 miles.

My check engine light came on after filling up with gas, after checking the purge valve cantilever was bad, I bought it and had licensed mechanic who owns his business replace it. Once again the check engine might came on. The error was cylinder 4 miss , I was told either the spark plug or coil was bad. My mechanic said ger coil and if that's not it he would replace spark plugs. I purchased the coil for a four cylinder engine because that's the only way they come. My mechanic took off the part which was broke and upon taking it out.he saw water in the coil holder and told me this was bad. He suggested I look up recalls on my vehicle upon which I found e recall on the puge valve along with a recall on the coil system which described the same problem of water leaking into the engine. After call recall department I was told they would cover the purge valve repair but there was no recall attached to my vin on other problem which should be. I bought the car with 28000 miles on it and have less than 44000 on it now. It should be covered under thus recall I have done all maintenance required and don't put many miles on it. I am a retired individual living on a budgeted income and thus problem should be covered under recall as it is the same problem as others have had. My

The turbocharger in this vehicle cracked at around 50,000 miles and my mechanic predicts it will happen again after another 50,000. This makes the vehicle unable to accelerate at unpredictable times, making the safety of the driver of the vehicle, as well as others on the road, compromised. My mechanic believes this is a common problem with GM vehicles of this engine size. Please advise. Thank you.

The turbocharger cracked at only 50,000 miles. My mechanic stated it is a common issue with this engine size.

2 years ago, my mother, previous owner, replaced water pump with dealership in Colorado. The car was around 2.5 years old. And less than 30,000 miles. About 6 months ago my overflow container was so hot it cracked. Idle hot came on. New container was purchased. 2 months less ago my car started to idle hot according to message on speedometer and NO hot temp was visible. Also, no check engine light was on. Water pump went out again. Less than 70,000 miles. Replaced water pump. Thermastat. Thermostat housing AND overflow because warped lid due to HOT. This weekend (XXX) my car has no check engine light, less than 70000 miles. Ran hot again. Smells like an oily sweet smell. Looked at oil cap. Milky substance. Appears head gasket is now out.

The contact owns a 2019 Chevrolet Trax. The contact stated while driving 75 MPH, the vehicle lost motive power and decelerated dramatically. The check engine warning light was illuminated. The vehicle was steered to the side of the road and inspected. The vehicle was then taken to the residence. The vehicle was taken to a dealer where it was diagnosed that the turbo had failed. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 46,000.

The contact owns a 2019 Chevrolet Trax. The contact stated that while his wife was driving at an undisclosed speed, she heard an abnormal sound coming from the hood of the vehicle. The contact’s wife veered off the road to inspect underneath the hood of the vehicle when the radiator cap popped open and burned the contact’s wife. The vehicle was taken to the dealer where it was diagnosed, and it was determined that the cooling fan had malfunctioned. Additionally, the electrical circuits failed and needed to be replaced. The vehicle remained at the dealer where it was being repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 80,000. The VIN was unavailable.

Upon acceleration above 40 mph, the car starts studdering with little power on acceleration. Releasing and pressing the accelerator until it starts picking up speed. This behavior worsened as the day went on. I had to put my emergency flashers on, while entering the highway ramp. Then it will pick up speed, just not rapidly as normal behavior on the accelerator. The stabletrax light came on, the engine light, tread lights. Then it drives normal until the next time.

The stable link light came on with the engine light and showed the car symbol with tread lines. This is the second time the stable link came on since my ownership. On accelerating the gas pedal, the car starts to studder, and the engine will not pick up speed on the highway. So cars are held up behind you, until it accelerates slowly to the highway speed limit. Between 44mph it starts studdering of power. It feels like a safety issue. It has started studdering at 35mph. I checked for recalls and found a lot of Chevys have this issue, but a different make and model.

I NOTICED THAT MY EXHAUST SMELLED STRONGLY OF HYDROCARBONS SO I EXAMINED AND PHOTOGRAPHED THE DIP STICK AND THE CRANK CASE OIL WAS A DARK BROWN AND SMELLED OF GASOLINE. THE TRAX HAS 3245 MILES ON THE ODOMETER AND MAY HAVE HAD WASTE OIL DUMPED IN IT WHILE MY WIFE AND I WERE ASLEEP IN OUR HOME WITH A GAS PORT.. THERE ARE SIGNS ON THE LOCAL HIGHWAYS OF ENGINE FAILURE SPEWING OIL ON THE ASPHALT AND WEAKENING THE NEWLY PAVED ROADS. *TR
