General Motors spent decades building cars that people liked. The Trax was a crossover vehicle not advertised heavily. The design of the car was similar to what else was being sold at the time. The reliability of the Trax was questionable at best and its build quality was cheap (via Readers Digest).
The CVT transmission was problematic and expensive to repair. GM didn’t offer a comprehensive warranty, and most drivers got stuck with the bill. The Trax offered reasonable versatility and gas mileage for the price, but when it came down to the build quality, it was lackluster at best.
