Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Engine overheating warning sounded. Looked at indicator and it was all the way in the red. Pulled over immediately. 30 seconds later the radiator blew with the force of an explosion, shooting coolant about five feet across the street even though the hood was down. Opened hood and found a hole in top of radiator, more than an inch in diameter. I would have opened hood before it blew so I came within half a minute of being badly burned. My mechanic said it happens regularly with Bmw 525's. He said it happens around 80,000 miles. My car had 75,000 miles. …”
