Vehicle now has about 1200 and when driving, the instrument cluster panel that digital shows your speed, odometer and other information on my vehicle went blank. It is just a black screen. When this happened, it caused the steering wheel controls for radio volume and turning the station to not work. With this, I have no safety features like lane assist now and can't tell my tire pressure.

20V811000 · Seat Belts:Critical Fasteners | Seat Belts

Reported: 2020-12-23 (December 23, 2020)

General Motors, LLC (GM) is recalling certain 2020 Chevrolet Bolt EV and 2021 GMC Canyon and Sierra 1500, 2500 and 3500, Yukon, Yukon XL, Cadillac Escalade and Escalade ESV and Chevrolet Blazer, Camaro, Colorado, Equinox, Silverado 1500, 2500 and 3500, Suburban and Tahoe vehicles. Incorrect bolts may have been used at one or more fastening locations to secure the seat belts to the vehicle. If an incorrect bolt was used, the seat belt may not be properly attached to the vehicle.

Consequence: If a seat belt assembly is not properly attached to the vehicle, the seat belt may not properly restrain an occupant in the event of a crash, increasing the risk of injury.

Remedy: GM will notify owners, and dealers will replace the suspect bolts, free of charge. The recall began January 29, 2021. Owners may contact GMC customer service at 1-800-462-8785, Cadillac customer service at 1-800-458-8006, or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N202322230.

While driving on the highway at speeds above 60 MPH, the engine shut off. There was a slight shuttering immediately prior, but no other indication. I had to pull over, across three lanes of traffic, during rush hour, in a fairly heavy rain and became a disabled vehicle on the shoulder. After being towed to the dealer, it was determined that the fuel pump was faulty. The vehicle had 4,954 miles on it so there was no reason for this part to have failed so early.
