FIRST GENERATION TESLA MOTOR FAILURE

EV Channels Review

This video delves into the internal mechanics of a first-generation Tesla drive unit, specifically addressing a grinding noise experienced by the owner after 40,000 miles. The host, Rich, and his associate, Lee, meticulously disassemble the unit, revealing worn-out bearings and a motor shaft that is beginning to chip. While replacing the bearings temporarily resolves the grinding noise, the analysis concludes that the underlying issue of shaft wear will inevitably lead to complete motor failure. The video highlights the reliability concerns of early Tesla drive units, contrasting them with later revisions. Although the repair is presented as a learning experience, the overall sentiment suggests that these early units have a limited lifespan, particularly when subjected to the stresses of a salvaged vehicle. The content is informative for those interested in the longevity and repair of older EVs.
