Every week it's something different. In motion... no Cruze control. No audio. Don't drive over 50mph brake problem. Parking brake engages randomly and without user engagement. No AWD. No stability traction. This happens so frequently the dash indicators have been reduced to 'idiot lights'. at what point do I become concerned" things appear to resolve when the engine is turned off and back on, sometimes....I compare it to other glitchy technology. However I potentially could be at an 80mph crazing speed when I decide to ignore the idiot lights...what happens when a real problem presents and I ignore the dash indicators do to frequent glitches" I'm so disappointed. My 2 previous Terrains were 10 times the vehicle the 2020 model year.
