Tesla says there is no “unintended acceleration” in Tesla vehicles

Tesla pushed back Monday against claims that its electric vehicles may suddenly accelerate on their own, calling a petition filed with federal safety regulators “completely false.”

Last week, the National Highway Traffic and Safety Administration said it would review a defect petition that cited 127 consumer complaints of alleged unintended acceleration of Tesla electric vehicles that may have contributed to or caused 110 crashes and 52 injuries.

The petition, which was first reported by CNBC, was filed by Brian Sparks, an independent investor who is currently shorting Tesla’s stock. Sparks has hedged his bets and has been long Tesla in the past, according to the CNBC report.

Sparks told CNBC on Monday, after Tesla issued its denial: “I am encouraged by Tesla’s commitment to continue cooperating with NHTSA, and I expect we will learn shortly why Tesla owners report unintended acceleration much more frequently than owners of other vehicles.”

Check out the response from Tesla below:

This petition is completely false and was brought by a Tesla short-seller. We investigate every single incident where the driver alleges to us that their vehicle accelerated contrary to their input, and in every case where we had the vehicle’s data, we confirmed that the car operated as designed. In other words, the car accelerates if, and only if, the driver told it to do so, and it slows or stops when the driver applies the brake.

While accidents caused by a mistaken press of the accelerator pedal have been alleged for nearly every make/model of vehicle on the road, the accelerator pedals in Model S, X and 3 vehicles have two independent position sensors, and if there is any error, the system defaults to cut off motor torque. Likewise, applying the brake pedal simultaneously with the accelerator pedal will override the accelerator pedal input and cut off motor torque, and regardless of the torque, sustained braking will stop the car. Unique to Tesla, we also use the Autopilot sensor suite to help distinguish potential pedal misapplications and cut torque to mitigate or prevent accidents when we’re confident the driver’s input was unintentional. Each system is independent and records data, so we can examine exactly what happened.

We are transparent with NHTSA, and routinely review customer complaints of unintended acceleration with them. Over the past several years, we discussed with NHTSA the majority of the complaints alleged in the petition. In every case we reviewed with them, the data proved the vehicle functioned properly.
