Why can't the car start with one-button start and the brake pedal is stuck?

The reasons why the car can't start with one-button start and the brake pedal is stuck are: 1. No fuel: This is basic common sense, the car won't start without fuel; 2. Battery failure: If the car battery is dead or malfunctioning, naturally it can't start; 3. Spark plug issues: Spark plugs are key components of the car's ignition system, so if they don't work properly, it affects the car's performance and efficiency; 4. Excessive carbon buildup: Too much carbon buildup in the vehicle can also prevent it from starting, so it's necessary to regularly clean the carbon at a 4S shop.
I've encountered this issue before. The push-button start won't work and the brake pedal feels rock hard - it's mostly caused by the vehicle being shut down for too long. After engine shutdown, the brake vacuum booster gradually loses its vacuum assistance, making the pedal as hard as a rock. Meanwhile, the push-button start system requires you to press the button while stepping on the brake to activate. If you can't press the brake, the button won't respond at all. The failure to start could be due to a weak battery or starter motor malfunction. I had this happen once after a business trip - my car sat for two weeks with critically low battery voltage, leaving everything unresponsive. After getting a jump start from roadside assistance, everything worked fine. My suggestion: try pumping the brake pedal a few times before starting to build up some vacuum. If that doesn't work, check the battery condition or seek professional repair services. Don't force it and risk damaging your vehicle.
With more experience, I find it quite common for brake pedal stiffness and startup failure to occur together. The loss of vacuum assist after engine shutdown is normal, but modern vehicles require brake pedal depression to start – if it's too stiff, the system gets stuck. The likely cause is insufficient battery power affecting overall system voltage, temporarily disabling brake assist. Check if interior lights illuminate: if yes, try pressing the starter button while firmly depressing the brake; if not, the battery needs charging or replacement. Another possible cause is switch failure, which I've encountered in older vehicles. Recommended habits: pump brakes several times before shutdown to maintain vacuum reserve, or regularly test battery voltage as preventive maintenance.
These two issues are intrinsically related. The inability to press the brake pedal is typically caused by vacuum loss after engine shutdown, which is a physical principle. Starting the vehicle requires pressing the brake to activate the system, but a stuck pedal hinders the process. Failure to start may stem from a weak battery or related malfunctions. Their co-occurrence often points to power supply issues or system bugs. Don't panic—first ensure the key is within sensing range and try a few more times. If unsuccessful, seek professional service; a simple check can mitigate risks.
