Since my error message two months ago I have not had a reoccurrence of the problem. Probably not what you want to hear but my system works as intended, in fact yesterday it updated itself with additional information.. Mine is a 2020.
My 2020 Denali pulled the same trick while driving down the road, when I stopped the engine and started it again the problem no longer existed. I had GM run a diagnostic and it came back all ok. Take your truck to a dealer and have them run a diagnostic of the infotainment center.
Jlong, I bought a 2019 Jeep Cherokee....It did not have a key plus other electronic items to relieve me of having to use my brain. The worst were the stupid no key system and the other was having to press a button after every start to keep the engine from shutting off every time the Jeep came to a stop....I hated these additions to what was an otherwise smooth ,quiet and fun vehicle...I sold it!
I can truly say I am glad I bought my 2020 Canyon rather than wait for a front end rework that would give me nightmares...sorry but the photos would send me home from the dealership with designs on keeping the current truck a lot longer. There I gave my opinion without ever using the word “hideous”.
I have ordered a 2020 Denali to .replace my 2017 Denali, both with eight speed transmissions. I really liked the way the eight speed performed on two trips to Texas (10,000 miles total) and mileage up to thirty MPG (28 average for the second trip:). I have yet to take one of my Canyon’s to a dealer for any repairs whatsoever ( the current ordered Denali will be my fifth). Although some have had problems my truck was trouble free from delivery to trade in.
I decided that since I had Memorial Day off so could my truck and drove the lawnmower instead......cut the lawn better than my Denali would have anyway.
