I took my car in for routine maintenance service and requested them to investigate a rattle noise when the car is started and when it idles. The vehicle was around 96K mile range. The repair center said it was the fuel injection system and it was normal. Fast forward to now, I have 111k miles, same rattle noise, and took my car back to shop for routine maintenance service and investigation into the rattle noise. It's the timing chain. Timing chain was stretched to the point where it couldn't be tightened and had to have over $4000 worth of repairs done to replace the chain and other damaged components. I pulled my owners manual and even searched online for the OEM recommended inspections for major components of my car and nothing about having timing chain inspected at any specific mileage point, or any other major components that could fail are listed for major components that could be inspected for wear and tear at said mileage milestones. The fact that prior year models had recalls due to failed timing chains, you'd expect to see following year cars, of the same body style, to have a heightened recommended inspection schedule to make sure the solution to the prior recall worked.

I started my car at a CVS parking lot. When I made a turn, the car was out of control and I couldn't stop or turn the car. My car hit other three cars in the parking lot and finally stopped. The OBD-II code check later indicated a "Engine misfire detected". I once got a recall letter from GM for the following issue. Not sure if this accident is related to this issue. "Inoperative purge solenoid that could lead to excessive fuel vapors entering the combustion chamber from the fuel tank. This condition could result in no start, idle stall and possible drivability issues such as hesitation." The good thing is nobody got hurt in this accident.
