Example complaints

“I and numerous others have had problems with the instrument cluster pixel on the Bmw 525I vehicles, which makes it extremely difficult to read whether you have a engine concerns or worse if the engine is overheating, etc. This could be potentially hazardous and the manufacturer is well aware of the problem, and they have even repaired a few bmws at no charge. However, when I notified the company of my complaint, they advised me that they would cover 25% of the parts and labor, and leave me to pay the remaining $452.00. …”
NHTSA complaint #10452436, filed 2012-03, 187,000 miles“The battery warning light fails to illuminate when the car's alternator fails. At idle a voltmeter read 11.5v.

I removed the battery from the car and attached it to a smart charger. The charger started out reading lo. My charger reads lo when the charge is less than 50% or so, and above that reports estimated charge in increments of 10%.”
