Tesla is facing allegations that it's trying to minimize complaints about performance. Reuters sources claim the company had a secret Diversion Team in the Las Vegas area to cancel range-related service appointments.

If a customer complained the range didn't live up to marketing claims, advisors would tell owners that Environmental Protection Agency (EPA) range figures were just predictions and battery degradation would reduce range. Tesla supposedly began tinkering with range estimates a decade ago to exaggerate figures when an EV was fully charged. Cars would only begin showing more accurate range numbers below a 50 percent charge. The company also used a 15-mile range buffer when the estimate reached zero, much as combustion engine cars still have fuel in the tank when the gauge reads empty.
