What owners wrote
Tl* the contact owns a 2018 GMC terrain. The contact stated that the vehicle's electrical system failed. The vents located near the instrument panel emitted a strong burning odor when the heating system or air conditioning system was activated. In addition, the front end of the vehicle exhibited a strong vibration that caused the steering wheel to vibrate. Furthermore, when the rear hatch door was closed, the rear hatch door light remained illuminated.
I got a diagnostic alert: service the enging and transmission system in your 2018 terrain within 7 days. The code was p050f. I have a little over 10,000 miles on here.
