2021 Chevrolet Trax Reliability Report

The digital instrument panel flickers, goes black, and sometimes stays dark for hours. That hides the speedometer, fuel range, tire pressure, and oil life. One report traces it from early CarPlay dropouts near 20,000 miles to a panel that glitches from about 60,000 miles and is now off more than on. Other filings in this category describe a battery that keeps dying because the alternator does not charge, a failed AC compressor, and a corroded exhaust flex pipe that leaked carbon monoxide into the cabin and caused stalling in traffic.

Under hard braking the car pulls sharply to the right, then the pedal turns spongy and sinks to the floor. In one case the dealer traced this to the master cylinder within the first 6,253 miles. Two of the filings are the same report submitted twice. A separate complaint describes a brake pedal that sticks down and has to be pulled back by hand. A brake positioner replacement did not fix it, and it came back after three dealer visits. Another filing, at highway speed, is really an engine and transmission power loss.

The check engine light comes on, the engine loses power and shakes, and heavy smoke pours from the exhaust. In one case a fuel trim fault was repaired, then the same symptoms returned the next day with a turbocharger code, at 33,440 miles. Another complaint describes a check engine light that keeps returning and a reduced power warning. The code pointed to the crankshaft sensor while the dealer blamed the catalytic converter. Sudden power loss in traffic is the main safety risk.
