My vehicle comes to an abrupt stop while driving or when Iâm pulling off at an intersection. This has happened on 4 different occasions in which Iâve injured my knee due to the vehicle stopping at random while Iâm driving or pulling off. Iâve 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. Iâm 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 stated it should fix the problem. This was about a month ago. Today on 08/08/2025 it happened again and I also hit my knee injuring it even more than more. Iâm still in a brace and now have to re-evaluated to see if the abrupt stop caused more injury. This is dangerous because my entire body jerks and cars are coming up behind me in the road and I can get into an serious accident. I need something done about this.
