Engine showing PO128 code. Steering Assist System reduced power. Engine fan constantly running. Engine temp on dash is stuck on the "C" mark, doesn't move. Thermostat and temp sensor replaced, issue continues. THIS IS A VERY COMMON PROBLEM ON GM VEHICLES WITH THE 3.6L AROUND THE 60,000 MILE MARK. GM NEEDS TO GET IT FIGURED OUT.

Not sure if this is your typical safety issue. Voice activation button @ RH side of steering wheel failed approx. one month after vehicle purchase. This button allows one to call out, use GPS, vehicle functions, radio, etc "handsfree". Message @ infotainment screen stated "click here to purchase subscription" which I was not made aware of by anyone involved w/ sale. Cell phone will link up w/ vehicle manually for sending or receiving calls, but requires holding phone to start or end them (and pick who you want to call)...which is illegal in California and unsafe. Inquiring w/ Onstar led to having to pay for monthly subcription to "reenable" functionality. Seeing as this IS a safety item, I wonder why I would be required to pay a monthly 45.00 fee for it to function. Had a 2015 Ford that worked perfectly...for free

Intermittent drivability issue involving the transmission during takeoff from a complete stop, most noticeable in heavy traffic and stop and go conditions. Vehicle shudders and lurches when accelerating from a dead stop, with a sensation similar to being hit from behind followed by abrupt engagement. This creates unpredictable launch behavior and raises concern for safe acceleration in traffic, including potential risk when entering intersections or merging. In addition, vehicle has a recurring squeaking noise on cold start that sounds like a belt or pulley related issue. Also experiencing an HVAC airflow malfunction where the center dash vents initially blow air, but within about 30 seconds the center vents stop and airflow shifts to lower vents and or upper dash vents only, affecting normal climate control and potentially defogging or visibility depending on conditions. Issue has been reported to authorized service centers, but the transmission concern has been difficult to duplicate and remains unresolved.

On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.

Cylinder 7 lost compression due to Cylinder 7 Exhaust AFM cylinder not moving. this is the second time I have had this issue in a little over a year. at the time of failure while driving the vehicle lost all power and would only run 25 - 30 mph causing me to have to veer off on the shoulder. yes it has been reproduced Register Chevrolet has it in the shop now and have found the same issue as before there were no warnings other than a slight backfire and then a severe engine misfire.

Service Brake Assist message appeared on the dash, brakes got soft , vehicle would not stop. Check engine light came on. Dealership reported no codes were reported but the Power Brake Booster Vacuum Sensor & Hose Assembly needs replaced due to a sensor malfunction. Say it is not covered under any safety/service bulletin so we need to pay for it. Other make and models are covered under 17-NA-314, Special Coverage Adjustment N182202780, Product Safety Recall N202300860. All similar issues but none for the 2018 Chevy Trax. Feel this is a huge issue as it is a direct issue with safety. Brakes are a critical part of safety when on the road.

My recently purchased 2008 was taken to the local chevy dealer for gas fumes in the garage. The technician reported "The smell is coming from the sending unit on the driver side. There was fuel dripping down the side of the tank and the tank was wet. So the sending unit needs to be replaced" The car has only 16,427 miles on it and has been garage kept. I believe that leaking fuel is a very serious safety issue and that the now expired special service bulletin 150682 should have been a mandatory recall.
