I pulled out onto Southside Blvd. My brakes failed, my driver’s front of the car hit a Waste Management garbage truck right back tire and cut the sidewall of the tire. The engine was racing, the truck pulled off the road, and I had sudden unintended acceleration. I immediately turned into a strip center and my car was racing through the strip center, the brakes were not working, the car controls were not working, and I turned the ignition switch off and the car stopped. The car had to be towed. Presently my insurance company has issued an estimate to repair the cosmetic issues, but not the mechanical issues.

In Oct 2022, I was driving normally and suddenly got a message on the dash saying something like "Coolant low, please top up when you have a chance". A minute or so later, I got the red warning "Engine Overheated, turn off engine when safe" and it went into limp mode, and I pulled over immediately and had to flatbed my car to a dealer. Then told me there was a coolant leak (which I was not aware and there was no error message regarding coolant prior to the incident.) And they told me there was a recall on my vehicle coolant vent line. Although I had check NHTSA website frequently and did not see anything being recalled. They replaced the coolant vent line for free. Fast forward 21 months and less than 5000 miles later, I brought the car in for oil change. Upon inspection of my vehicle, the technician noticed some fluid seeping through the turbo coolant feed line and there were buildups. Please see video here. [XXX] . They suggested replacing the turbo coolant feed line and turbo return light for $2,500! I mentioned the incident two years ago due to a coolant leak that was being recalled, if this is related. They told me the recall was only the coolant vent line. The issue now is the turbo coolant feed line and return light. And over time, the coolant just "starts to leak on those lines due to its material". This is a 6 year old mildly driven vehicle with 35K miles. How can the coolant line material so bad that it would start to leak after 5+ years? Found some threads online and there were other people having the same issue. The manufacture should have put in some quality coolant lines. There were other recall in other models (18V755) for regarding a coolant leak that may result in an engine fire, which increases the risk of a crash and injury. If the line material of my coolant feed and return line by nature will start to leak after five years, wouldn't it be the manufacture's responsibility to remedy it before it cause safety issue?
