I purchased a 2003 Honda Element in June 2003 of which had many mechanical and electrical problems/failures. The most significant of these failures proved to be with the drive train mechanism specifically cv boots and steering function. Loud noises developed when turning which grew louder over time as well as a "grinding" sound and vibration from underneath approx. At mid-ale location. The automatic transmission began to slip out of reverse while moving into neutral at will. These issues culminated in my steering ceasing to operate as though "frozen" while I was making a slow left hand turn causing the vehicle to crash into a tree along side of a major street and intersection. The driverside air-bag did deploy and the vehicle was completely in-operable and had to be flat bed towed due to the severity of front-end damage. I completed and maintained all scheduled maintenance stop requirements and yet suffered catastrophic drive train failure at only 82,000 miles. My research on this make/model failures proved to be numerous in number as reported on verifiable/reputable websites. One of which was Honda's own - technical service bulletin's site!.
