What is the brake failure issue with the BenBen e-start?
4 Answers
The brake failure issue with the BenBen e-start is caused by a batch failure of the vacuum pump, and the manufacturer provides free replacements for customers. How the vacuum pump works: New energy vehicles use an electric pump to simulate the vacuum boost of an engine. The vacuum pump maintains the vacuum level in the boost system above several tens of kilopascals to provide sufficient braking assistance. Vacuum pump failure: When the system's vacuum level drops, the electric pump activates to replenish the vacuum, which is why many new energy vehicles produce intermittent working noises. When the electric vacuum system fails, it results in insufficient vacuum similar to an engine stalling in traditional cars, causing the brake pedal to become increasingly hard, which may ultimately lead to serious accidents.
I've been driving the BenBen E-Star electric car for almost two years now, and last month I experienced a sudden brake failure that nearly caused an accident. It happened on a city road when I pressed the brake pedal but got no response, which really panicked me. After checking later, it might have been a brake booster system malfunction or an electronic software bug. The BenBen's regenerative braking system sometimes has issues that affect overall brake response. I recommend owners regularly check their brake fluid and not wait until the warning light comes on. When parking, frequently test brake sensitivity using the parking function. If you encounter similar situations, stay calm - immediately turn on hazard lights and slowly decelerate to a safe spot. Safety should always come first. I've already scheduled a 4S shop visit to replace system components, and now driving feels much more secure. Car maintenance service is crucial - don't skimp on upkeep costs.
As a long-time car repair professional, I've found that the common causes of brake failure in the Benben E-Star are quite numerous. Electronic control unit (ECU) malfunctions are the primary culprit, often due to program conflicts or sensor false alarms. Mechanically, brake fluid leaks from the master cylinder or piston wear can also lead to failure. The unique regenerative braking system in electric vehicles, if improperly engaged, can actually make brake response sluggish. With the Benben model in particular, special attention should be paid to missing software updates—some users ignore recall notices. I've encountered numerous cases where voltage instability caused component burnout. I recommend owners perform monthly self-checks of brake fluid levels rather than waiting for emergencies. Having a professional shop scan the control module with diagnostic equipment is inexpensive but provides peace of mind. Developing good maintenance habits can significantly extend the system's lifespan.
Brake failure is extremely dangerous! I once experienced a brake failure with the BenBen E-Star on the highway. I immediately pulled up the electronic handbrake and shifted to a lower gear to slow down and avoid a rear-end collision. Common issues with the BenBen often involve the brake booster or circuit disconnection. Don't drive recklessly; after pulling over safely, check under the hood for hydraulic pipe leaks. Remember the safety procedures: maintain steering control and avoid sudden steering wheel movements. BenBen owners should regularly test the brake response sensitivity and visit a 4S shop for firmware updates or sensor checks if any abnormalities are detected.
