| Description of the problem | I was traveling at about 40 miles per hour on a major street and went over a small pothole. This resulted in major fractures on both of the passenger's side wheels. All the equipment on this car is original from mercedes benz. This is the first incident in late 2010. Recently, i was traveling about 35 to 40 miles per hour and went over a small pothole on the street that is about 6 inches in diameter and less than 2 inches in depth, and resulted in another wheel failure. I understand that pothole damage is a normal part of wear and tear. But this is a major street that has traffic count of 75,000+ car per day. If my car is this easily damaged in a period of 1 year, i can't even imaging how many cars would get damaged on this stretch of road. Therefore, i believe wheel failures such as this at relatively average speed and small potholes, can't just be a result of normal wear and tear. I believe this is either defective design or poor product quality control. If my wheels get damaged at this speed, i can't image what kind of damage or safety issues it would cause when i'm traveling on freeway at higher speed. |
