NHTSA complaint #10003345, filed 2003-01, 28,000 miles2000: “While driving in massachusetts on 495n at about 5:30pm I smelled something burning. Checked my gauges and all seemed well, thought it may be a wood burning stove in the area I just kept driving. I turned off rt495 and onto rt 119. About a mile down rt119 I noticed a lot of smoke building up inside the car, I then realized my car was on fire and before I can pull off the road the inside of the car filled with smoke and burned my eyes and I was choking a lot. I slammed it into park, shut the key and jumped out the car. …”
NHTSA complaint #10212302, filed 2007-12, 138,000 miles1999: “Radiator failed on my 1999 Bmw 540 at 54,700 miles. I believe this to be a safety problem that Bmw needs to address. This safety problem: - disables the vehicle no matter where you are from rush hour traffic where the panic could endanger other drivers, to the middle of nowhere in the dead of winter by yourself. - steam from failed radiator blocks vision of the road, or whatever else is in the drivers side front corner of the vehicle. - failure can not be predicted by visual inspection of the radiator.”
