My truck, which has a 6.2 V8 L87 engine, seized up on the highway while on a road trip. The engine suddenly died with no warning or alerts on the dash. The mechanic told me that the oil pan was full of metal and the engine was completely seized. The engine needs to be replaced entirely at just under 40K miles. I have been diligent in taking the truck in for regular service at the dealership, and I had no indication of any problem with the vehicle until it died on the highway while traveling at 65 mph.

We were driving our truck with our family on vacation. We were going slowly entering the parking lot to our hotel when a sudden loud grinding noise caused our truck to shudder and shake. We stopped and got out and didn’t see that we ran over anything. We started to proceed and the sound was the same. We parked in a stall and left the vehicle overnight. No check engine lights were on. No warnings at all. It was Memorial Day weekend 2023. There were no dealerships open where we were vacationing, 3 hours from home. Very inconvenient. Later when the dealer looked at it, the thrust bearing was bad and the engine was shot. Needed a full replacement at 10,600 miles.

2023 Silverado with 10 speed transmission. 20K miles. On 11/30 received "Reduced Power" message, quickly followed by "Service Transmission Now Unable to Shift Soon", which was quickly followed by "Service Transmission". CEL came on. Transmission was shifting erratically, and not shifting into higher gears. Clearly a safety concern. Dropped it off at a local dealer on 12/1. Dealer service advisor contacted me 12/12, saying they were finally able to diagnose the problem and the transmission needs a new valve body. However, the valve body is on back order and there is no estimated time for when it will be available. The internet is awash with stories of the same issue with GM's 10 speed transmission in the light duty pick up trucks, leaving owners waiting for weeks, even months before their vehicle is repaired.
