GM has issued a service bulletin for certain units of the 2024 Chevy Trax which may have water leaking through a defective roof seam weld from the outside when the vehicle is exposed to rain, snow, washing, and so on, causing a variety of problems inside the cabin.
Water entering through the roof and being present inside the vehicle, as well as signs of water intrusion such as bubbled paint, rust and corrosion along the interior roof seam, are among the signs this defect exists and an incorrect brazing weld was applied to the specific 2024 Chevy Trax unit’s roof during production.
Several other symptoms are possible as a result of pinholes or cracks in the roof weld. The leaking often affects certain electronics within the 2024 Chevy Trax and causes them to become inoperative. The shifter light may become non-functional, as may the crossover’s key fobs. Other problems may occur with the remote control door lock system.
GM warns that repairs should not be carried out by do-it-yourselfers, but should be completed only by official Chevrolet service personnel to ensure the work is done correctly and is carried out under warranty. Affected vehicles are found among those produced between the start of regular production (SORP) for the model year and August 18th, 2023.
Once inspection has verified the presence of a holed or cracked laser brazing weld at the roof seam, dealership technicians are instructed to fix it by using a sealer product to fix the holes. Damaged paint may need to be touched up with the appropriate color, and damage to electronics corrected to ensure proper function.
The repair is typically covered under the bumper-to-bumper warranty of the 2024 Chevy Trax crossover. The service bulletin number is 23-NA-107.
As a reminder, the 2024 Chevy Trax introduces the second generation of the Bow Tie’s subcompact crossover with numerous interior and exterior changes and updates, including significant dimensional changes. The all-new model is motivated by the turbocharged 1.2L I3 LIH gasoline engine rated at 137 horsepower and 162 pound-feet of torque. The engine connects to the GM six-speed automatic transmission, with only a front-wheel drivetrain configuration now offered for the vehicle.
