general problems of the 2021 Chevrolet Silverado 1500 - part 2

My best friends truck, a 2021 Chevrolet silverado had a brake failure a July 2021. Was coming up to an intersection to make a left turn and went to press the brake pedal to slow down for the turn. Pedal went all the way to the floor and the truck wasn't slowing down much at all. Multiple brake system warnings and lights came on the dash along with the check engine light. It got towed to the dealership he bought it from. They replaced the brake system control module and said it's good to go. Maybe it is, maybe it's not. There have already been 2 recalls pertaining to this exact issue released, none of which applied to his truck according to the VIN recall checker on gm's website. If the problem has been figured out and fixed, then it wouldn't still be occuring. This is a major safety concern, one that I feel people need to be aware of. Which is why I'm sharing what happened to my friend's truck on behalf of him. This situation is exactly why the emergency brake on vehicles is an all mechanical system that allows the driver to quickly and directly be able to apply the vehicles brakes. It's a reliable and dependable system that's been implemented for over a century. This is a prime example of why vehicles still need to have one onboard. This vehicle doesn't have a real emergency brake. There was an emergency in which the vehicles primary brakes failed and weren't able to slow down the vehicle. The little "emergency brake" button was more worthless than the main brakes that failed to do their job on this truck with less than 5,000 miles on it because the emergency brake system on this truck has worked 0% of the time it was needed so far. This isn't some engine misfire, sunvisor defect, or bluetooth pairing problem, this is an out of nowhere total brake system failure. This is not good. And people need to be made aware that the problem is still occurring, and on vehicle's that gm isn't aware that it may be applicable to according to the absence of any recalls per VIN.

Purchased new Chevrolet silverado at4 last week and with only 72 miles on the odometer a warning light appeared on instrument cluster stating “service brake assist”. Returned to dealer where purchased with 91 miles on odometer 3 days later. Dealer service department confirmed a faulty brake control module and ordered replacement part. New brake control module will arrive in 4 days and will be installed at that time. In the meantime, service manager said vehicle is safe to drive with existing brake control module. This is being submitted because of previous significant vehicle recalls on record for the same issue in 2018-2020. It appears the problem or some iteration of the problem has not been corrected yet in the 2021 models.

Faulty lifters causing the truck to throw piston rods. This causes malfunction of the traction control, parking brake, transmission,auto locking rear differential. I have had my truck in the shop 3 times for the same issue all within the 1st 10,000 miles. This particular motor has been taken out of production. Upon speaking to mechanic managers at multiple gm dealerships they were not surprised and personally gave me advice on the lemon law. My truck, which is my 1st brand new vehicle, has been out of service now for a total of 45days. I have still made payments up to date. The dealership offers a car or small SUV while repairs are being completed, not a truck! beware of the 5. 3litre ecotec3 v8 motor.
