Tesla was said to be so swamped with complaints about driving ranges that it created a secret team to cancel owners' service appointments.

• Tesla exaggerated the driving range of its vehicles for years, Reuters reported.
• To suppress complaints, the EV maker created a secret team to cancel appointments, the report said.
• The cars often did not need to be repaired and the performance had merely been overstated, it added.

Tesla exaggerated the driving range of its EVs for years, an investigation from Reuters found.

The report, which cited a source familiar with an early design of Tesla software, said the EV maker rigged the range-estimating software on the cars' dashboards. Instead of displaying the true driving range, the software provided a "rosy" projection of how far cars could drive before needing to be recharged, the report said.

The distance EVs can travel before needing to be recharged is one of the main disadvantages the cars face in comparison with gas vehicles.

One unnamed source told Reuters the order to inflate the driving range displayed on the cars was given by Tesla's CEO Elon Musk about 10 years ago.

As a result, the company was inundated with complaints and service appointments from drivers who expected a longer driving range, several sources told Reuters.

To suppress the volume of these complaints the automaker created a secret "Diversion Team" in Las Vegas to cancel appointments, Reuters reported, citing sources familiar with the matter.

The team was tracked by the number of appointments it diverted each day and often closed hundreds of cases a week. In most cases, the cars probably did not need to be repaired; their performance was merely overstated.
