2021 CADILLAC ESCALADE ESV Unknown Or Other Problems

My vehicle comes to an abrupt stop while driving or when I’m pulling off at an intersection. This has happened on 4 different occasions in which I’ve injured my knee due to the vehicle stopping at random while I’m driving or pulling off. I’ve stated this to Cadillac of Memphis and to Landers GMC. The first time I happened I hit my knee by the control panel on the driver side. I’m in a brace because my patellar tendon are inflamed and as well my hoffas fat pad due to the impact. Cadillac of Memphis stated it was something that went out and needed to be replaced. They replaced the battery and another part. That did not correct the issue. It happened again after that repair. The third time it happened I was told it was because the transmission was about to go out. Landers replaced the transmission. The advisor...

Twice in the last 6 months the vehicle doors have locked at random while the key was inside the vehicle. Both times, my children were trapped in the vehicle exposed to potential heat issues. Fortunately, in both cases the doors were able to be opened through another door that was still open one time and by hitting the unlock button through a slightly rolled down window. Breaking the glass was the next option. This is a serious safety defect that is putting young children and pets at risk for heat injury or death. There are no indications as to why this started, no warnings displayed, and seems to occur at random. Disabling autolock features does not resolve the issue meaning some glitch or equipment failure is causing the doors to lock despite all autolock features turned off.
