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.

The front exhaust flex pipe leaked by a corrosive hole that allowed exhaust and CO carbon monoxide to escape making the drivers dizzy, nauseated, and with a headache. This also caused the vehicle to smoke, run rough and stall in traffic. This also required the post 02 sensor to be replaced.

My car’s engine started to get loud one day and would run roughly as I drive. I got it check and the service center couldn’t find the issue as the car was good on all its fluids and there weren’t any leaks anywhere. Then some days passed and my vehicle started to slow down drastically on a highway (speed limit of 65) and my car would struggle to accelerate and so I was forced to switch from the middle lanes on the left to the lane all the way in the right, it was very difficult to do so as cars were passing me at high speeds. My car was struggling to accelerate and the engine started running rough. The engine light then came on. So I got it checked ant a local service center and I was told my turbocharger had to be replaced as it malfunctioned somehow. I can’t drive my car as it would be traveling way below the speed limit. I did not bring it to my dealer yet.
