While driving this summer, I had an alert pop up on dash “reduce engine power.” Car almost completely stopped on highway, almost causing a wreck. Took to dealership where they had my 2024 Trax for almost 2 months. Finally, the replaced the Turbo. Barely 2 months later, this part week, I was driving and my car started stalling out, wouldn’t drive… almost got in 3 wrecks with my kids in car - very unsafe to drive. Found out my transmission failed - the point of failure being the transmission cooler. For a not that old car, 2 huge issues in 2 months is ridiculous, and extremely unsafe. It was terrifying driving with my children recently and having my car just completely lose power- we almost got t-boned when it just stopped driving while crossing a very busy street, almost rear ended several times when it just wouldn’t drive. It is now at Chevy dealership not drivable.

I own a 2024 Chevrolet Trax purchased new in XXX. On XXX, the vehicle displayed a "Service Power Steering — Drive With Care" warning. I experienced difficulty steering, and later that evening the vehicle would not start. The instrument cluster also displayed abnormal behavior, which was recorded on video. On XXX, an authorized Chevrolet dealership in [XXX], diagnosed a failed battery and replaced it under warranty. On XXX, while traveling on the highway with my family, the vehicle displayed "Engine Power Is Reduced" and struggled to accelerate. I sought assistance at an authorized Chevrolet dealership in [XXX]. The warning was cleared but returned shortly afterward. I have photographs, videos, repair documentation, and call records supporting these events. I am reporting these incidents because of the potential danger posed by sudden steering-system problems and loss of engine power during travel. I request that these safety concerns be reviewed for possible defects affecting this model. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle suffers from an extreme, unresolved internal crankcase pressure defect stemming from the factory 1.4L Ecotec PCV system and intake manifold check valve. This pressure cascade has caused a total turbocharger failure, multi-gasket oil blowouts, water pump failure, and has now completely blown a critical coolant housing hose off its connection, causing total coolant evacuation. The vehicle is currently parked and available for inspection upon request. The safety of the driver and minority passengers is severely compromised. The vehicle actively smokes from under the hood when turned on, which worsens immediately when the cabin heater is utilized. This indicates highly flammable oil and coolant are leaking directly onto hot exhaust/turbo components, presenting an active vehicle fire hazard. Furthermore, the pressure defect previously caused a catastrophic engine oil blowout while traveling at highway speeds, risking sudden power loss, engine seizure, and traffic collisions. The vehicle is currently deemed completely unsafe to operate. The vehicle's core turbocharger failure was previously confirmed and replaced by an authorized manufacturer dealership under a factory warranty extension. However, the dealership failed to diagnose or repair the underlying PCV/intake pressure defect, causing the new components to fail immediately upon vehicle delivery. The manufacturer has been notified of the failure cascade but is refusing to inspect or intervene without requiring out-of-pocket consumer diagnostic fees. No police or insurance inspections have occurred. began over two years ago with random, intermittent check engine lights accompanied by random error codes, a high-pitched engine squeak, rough idling, severe fuel economy drops, and intermittent engine stalling. The engine eventually developed a heavy knocking sound resembling a diesel engine. Currently, the check engine lamp does not illuminate, but all physical symptoms remain active and increasing in sever

My 2017 Chevrolet Trax experiences intermittent engine rough running, hesitation and loss of power when accelerating from a stop. It runs especially rough around the shift into second gear. At idle, such as in a drive-through, the engine shakes and the RPM repeatedly drops and rises as though it may stop. This is near-stalling; I have not confirmed a complete engine shutdown. The unpredictable hesitation and loss of power when moving away from a stop raise concern that the vehicle may not accelerate adequately to clear an intersection or move with traffic. We drive it only short distances around town, not on the highway. Symptoms occur more often during or shortly after rain and in cold weather; it can run normally in warm, dry weather. Check-engine and StabiliTrak warnings appear intermittently during these episodes. The current symptoms were present before the October 2025 turbocharger replacement and continued afterward. The exact date they first appeared, and whether the warning lights preceded the symptoms, are unknown. There is a documented history of engine and turbocharger repairs. In February 2021, at approximately 91,586 miles, a Chevrolet dealership confirmed a cylinder 2 misfire, low compression, a cracked piston and a cracked turbo housing. All four pistons and rings and the turbocharger were replaced. Handwritten notes also document PCV hose replacement. An independent shop replaced the turbocharger again in October 2025 at approximately 195,510 miles. Its invoice records the complaint that the vehicle sputters when taking off from stop signs. Those symptoms continued after the repair. On October 6, 2026, at 197,216 miles, an O’Reilly scan recorded stored P0304 (cylinder 4 misfire) and P1101 (intake airflow system performance). A separate shop’s scanner also displayed stored P0304. These scans document codes, but the cause of the current intermittent problem has not been diagnosed. Another cracked piston or turbocharger failure has not been confir

September 20th 2026: I was driving my 2024 Chevrolet Trax up a grade (Mountain) approximately 11AM, Driving Normally at Highway speeds, normal highway conditions, temp outside was close to 100 Degrees Fahrenheit, suddenly with no warning half way up the mountain the car lost power, check engine light turned on (Engine Power Reduced) came on, I had no option but to pull over on the highway with only 41,500 miles on the odometer. Being over 200 miles away from my home I felt devastated. Made an appointment the next morning to have the car checked out by the Chevrolet Technicians at the dealership, they stated the Turbo completely failed, the part was on a slight back order they pushed through and it took a week to get this repair done. Previous to the Turbo failing, approximately at 36,000 Miles on the odometer on or about January of 2026: I get in my Trax and the A/C will not blow cold air, took it in for service at the same dealership come to find out the A/C condenser failed or ruptured leaking Freon, I paid $1,800.00 on an expense out of pocket that was not covered by any warranties.I Even purchased the extended warranty when I bought the car with 0 miles in November of 2023. Previous to the A/C condenser failing with no warning what so ever, on November 2025 I go open my car and the remote unlock feature does not work due to a completely dead battery car would not start or open. The car had to be towed to the dealership because after they jump started it the transmission started clucking really hard when shifting into Drive. The culprit according to Chevrolet Dealer Service Advisors was just a dead battery(covered by warranty) , yet the car gave no signals of a dying battery.after picking up Car I noticed rough idle and performance after this incident, I took it back to get checked out the same day and they could not “replicate” the symptoms, they stated that they can only fix it when the car blows up since it wasn’t showing any Check engine lights.
