One thought on “18036: Service Update – Stalk Incorrect with Auto High Beam – 2018 GMC Terrain Denali

  1. I purchased this 2018 GMC Terrain vehicle and it had this recall. I asked the dealer NOT to implement this recall simply because the feature works. I used it. It worked fine. He said it wont work and removed the stalk. I have become a very dissatisfied GM customer. This is my first return to GM since 1999 Pontiac Grandprix( a good car, btw). I had them reinstall the stalk, but they wouldn’t reprogram the ECM, they claimed it shouldn’t be required. Incompetence.
    3 errors in my judgement:
    1. GM shouldn’t have invoked recall for cars that the auto high beam feature worked. Their mistake installing it in first place. Eat it, suck it up. inexpensive part as it is. Unheard of for manufacturer removing a working feature for ANY product already sold!
    2. Dealer should abide by customer request not to implement recall.
    3. Dealer service manager was incompetent and arrogant.
