Mientras conducía el panel de instrumento digital donde están los relojes se apagó en su totalidad. El auto siguió funcionando pero no podía ver nada en el panel porque estaba literalmente muerto. Me moví hacia un costado de la carretera y apagué el carro. Lo volví a prender pero el panel siguió muerto. El carro si trabajaba. Llegue con mucho temor a casa y lo envié al concesionario donde lo compré. Me dijeron que era el panel de instrumentos y que lo tenían que cambiar.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2022 GMC Terrain verdict →
