What causes the car to display SVS and fail to start?
2 Answers
The steering wheel is in a locked and immovable state, among other issues. Below are the specific details: Locked steering wheel state: Simply apply force to turn the steering wheel while turning the key, and generally, the steering wheel lock can be quickly released, allowing the car to start almost instantly. Parking without shifting to P gear: If the car can start in D or R gear, the sudden movement of the vehicle upon ignition poses a significant safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), manufacturers preset this mode and repeatedly emphasize in the manual: ensure the gear is in the P position when starting. Smart key battery depletion: The start system cannot detect the weak signal emitted by the key. It is recommended to place the smart key on the start button and then press the button to start.
I remember last year my car also had the SVS light on and wouldn't start. At first, I thought the battery was dead, but jump-starting didn't help. Later, a car-savvy friend told me it might be related to sensors or the electronic system, like a faulty crankshaft position sensor preventing the engine from starting at all, or fuel system issues where the fuel pump isn't delivering fuel, making ignition impossible. It could also be a bad ignition coil causing the spark plugs to misfire. The most troublesome scenario is a software glitch, like a computer blue screen needing a reboot. Back then, I kept trying to start the car and almost damaged the starter motor, so I had to call a tow truck to take it to the repair shop. The mechanic used a diagnostic tool and immediately found a sensor error code—replacing the faulty part fixed it. Regular maintenance and checking wire connections are crucial to avoid being stranded. In short, if this happens, don't force it—safety first.
