A Tesla driver recently reported that their electric vehicle suddenly lost power and slowed down while being driven on a highway, even though the dashboard indicated 72 kilometers of remaining range. The driver stated that the car's speed dropped to only 60 km/h, creating a dangerous situation as there were elderly passengers, a child, and a pregnant woman onboard. The hazard lights were activated, and the vehicle was moved to the emergency lane. However, when the range dropped to approximately 60 kilometers, the car shut down completely, and even the hazard lights could no longer be turned on. After contacting Tesla’s customer service, the driver was informed that the battery was out of warranty and had become unstable. While the company offered to schedule an inspection, the driver would be responsible for the cost. The service representative also advised that on highways, the vehicle should be charged when the remaining range drops to 100 kilometers. The driver expressed frustration, stating that while battery degradation is understandable, losing power with over 70 kilometers of indicated range is unacceptable. They questioned the practicality of electric vehicles if a displayed range of 100 kilometers cannot be relied upon.
