Pretty Bummed Out
Matthew Laraway, 12/13/2020
2020 GMC Sierra 1500 4dr Crew Cab 4WD 5.8 ft. SB (4.3L 6cyl 6A)
Hopefully all will get resolved...coming out of a Tahoe with 110,000 miles and excited to get into my 2020 Sierra Denali 1500 Carbon Pro with the Duramax Diesel.
At this point, I have had the car 2 weeks and it has been back at the deal twice, this time going on 4 days. First issue was a coolant sensor that set off an engine warning and the second problem is car wouldn’t start due to … dead battery. Apparently 4 open recalls on the 2020 and I guess my dealer didn’t take care of them? They still can’t figure out what is draining the battery. Truck has about 900 miles on it. Now have the feeling of “what’s going to be messed up?” Every time I press the start button. Certainly takes the enjoyment out of owning this physically beautiful truck. When it works it is an absolute joy to drive and it is the best looking truck on the road....all that said....I want it gone.
