NHTSA Complaint #11455721 — 2018 CHEVROLET BOLT EV

In March 2021, I drove my Bolt in very cold weather, and parked the Bolt in my garage with only 7 miles range remaining. I did not plug in the Bolt to charge until 24 hrs later and found out the Bolt would not charge. The Bolt was towed to a local Chevy dealer for service. The dealer found two parts had failed. 1) Drive Motor Battery Coolant Heater, and 2) High Voltage Battery Control Wiring Junction Box. According to the dealer Part 1 was not warrantied, and Part 2 was warrantied. Here's my problem. Part 1 was replaced first but that did not fix the problem. Only after Part 1 was replaced did the dealer find Part 2 had failed. Obviously these two Parts are interdependent. Part 2 caused Part 1 to fail, therefore Part 1 should be covered by Part 2 warranty.
