NHTSA files every complaint against a named sub-assembly, not just a system. This is the difference between knowing it was "the engine" and knowing which part of it — the list to hand a mechanic.
Odometer readings owners gave when they filed. About half of all complaints include one.
A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.
Reports where the owner recorded a crash, a fire, an injury or a death.

POWER TRAIN
I was driving my car and heard a loud sound and then my airbags went off. I lost control on my steering and was able to coast the car to shoulder. The airbags deployed even though there was no collision with another car. Under further inspecting it looks as if all the bolts came loose on the drive Trane. I have no idea why the airbags went off. I did sustain an minor injury to my hand. police were called, fire trucks checked for possible fire hazards. I looked for recalls and or air bag malfuctions for this year make and model but did not find any. Had I not been in the far right lane I could have been in a serious accident. The airbags deploying scared me. Both the driver and passenger side airbags went off. I was the only one in the vehicle.

UNKNOWN OR OTHER
I was driving on Business Highway 85 in Thomasville, North Carolina on a clear, cool day. There were no other cars on the road, and no overpasses. While traveling at about 60 miles per hour, all of a sudden there sounded a loud bang overhead, like an explosion. I immediately pulled over to discover the sunroof was completely shattered, appearing to have exploded from the inside out, with the glass pointing upward toward the center. Luckily, the sun shade was closed or glass would have flown all over myself and my son in the backseat. Also fortunate that no other cars were on the road, as glass would have flown at any cars behind me as well. I reached my destination and cleaned up the glass and vacuumed it so as not to endanger anyone while driving. I have not had the car inspected yet, but it is available for inspection. There was no warning whatsoever of this happening, and I am certain nothing fell on the car. There was nowhere for anything to fall from and there was nothing in the crevice but shattered glass.
