Federal regulators dismiss claims of safety issues with Tesla's one-pedal driving system, rejecting a 2023 petition.
Federal regulators at the National Highway Traffic Safety Administration (NHTSA) announced they will not require Tesla to recall its electric vehicles over concerns of sudden unintended acceleration linked to one-pedal driving.
A Greek engineer filed a petition in 2023, alleging that Tesla's one-pedal driving system could lead to vehicles accelerating unexpectedly when parked, prompting NHTSA to investigate.
Understanding Sudden Unintended Acceleration
Sudden unintended acceleration refers to instances where vehicles accelerate without driver input, a issue that has historically affected various car models and raised questions about whether it stems from human error or engineering flaws.
In Tesla's case, NHTSA reviewed data and determined that one-pedal driving, which relies on regenerative braking, does not cause this problem, as engineers found no widespread evidence in their analysis.
Regenerative braking in electric vehicles like Teslas converts kinetic energy into electricity when the driver lifts off the accelerator, allowing the car to slow down without traditional friction brakes, a feature common in many EVs and hybrids.
Tesla implements one-pedal driving by programming the vehicle to stop completely when the accelerator is released, differing from other automakers who use separate brake-by-wire systems, and this design has been popular among some drivers for its efficiency in low-speed scenarios.
Driver Experiences with One-Pedal Driving
Some Tesla owners appreciate one-pedal driving for its similarity to engine braking in traditional cars, making it useful for city driving, while others prefer conventional braking methods.
Despite the petition, NHTSA's decision concludes that no recall is necessary for Tesla EVs produced since 2013, based on their evaluation of the system's safety.
