A Tesla Model S owner faced a potential $5,500 repair bill for a failed front drive motor but instead replaced a $70 encoder sensor, saving thousands. The car, bought for $10,300, displayed a dashboard warning about the motor, disabling it. Tesla's remote diagnostic estimated the motor replacement cost, but a YouTube video revealed the issue was often a faulty sensor, not the motor itself. The $5,500 quote made little sense for a car worth only ten thousand dollars.

The owner discovered the sensor could be sourced from a Mercedes-Benz electric crossover and replaced it after dropping the massive battery pack. Installation took hours but cost only $70. The fix worked perfectly, allowing the car to drive normally again.
