What to do if the ABS of Infiniti Q50 fails?
3 Answers
When the ABS fails, it is best not to continue driving, or rely on the conventional braking system to go to the auto repair shop as soon as possible. During the journey, you must drive carefully, slowly, and steadily, avoiding aggressive driving. The failure of the anti-lock braking system will also affect the ESP anti-skid system. A malfunction in the anti-skid system can cause the vehicle to skid during emergency braking or sharp turns, which is extremely dangerous. Here is a brief introduction about ABS: 1. The automotive anti-lock braking system, or ABS, is a device that automatically adjusts the pressure in the brake lines based on wheel speed when braking in an emergency, ensuring the wheels are always in a state of slipping between locking and rolling. Especially during emergency braking, it will perform intermittent braking—brake, release, brake—to avoid danger. 2. The anti-lock braking device performs pulsed braking—brake, release, brake—at a frequency of 6 to 10 times per second. It replaces manual control with electronic intelligent control to prevent wheel lock-up, ensuring the wheels always obtain maximum braking force while maintaining flexible steering. When the wheels are about to lock, the braking force is reduced; when the wheels are not about to lock, the braking force is increased. This repeated action ensures optimal braking performance.
As a long-time owner of an Infiniti Q50, I once experienced the ABS warning light coming on during a rainy highway drive when the whole car suddenly felt strange. I immediately slowed down and pulled over to inspect. First, I checked if the brake pedal felt unusually hard—this could indicate ABS failure. Then, I popped the hood, located the fuse box, and checked whether the ABS fuse was blown; replacing it only cost a few bucks. If that didn’t work, I’d clean the ABS sensors near each wheel—too much dirt buildup can trigger false alarms. Don’t underestimate this simple step—after cleaning them myself, the light turned off more than half the time. If the light stays on, never take it lightly—a severe ABS fault can double braking distance, making wet roads even riskier. That time, I took it to the dealership, where their diagnostic computer pinpointed a faulty left front wheel sensor. Replacing it fixed the issue. Never delay fixing this problem—safety always comes first.
Having dealt with numerous ABS issues on the Infiniti Q50, I've found the most common causes are wheel speed sensors clogged with mud or blown fuses. The first step is to scan for trouble codes using an OBD tool to determine whether it's a sensor issue or a control unit problem. Sensors are straightforward—just clean off surface dust and reconnect for testing. If a fuse is blown, replacing it is basic. However, if the wiring is aged or the controller is faulty, disassembly and inspection are necessary. Avoid tampering randomly to prevent damaging more components. When the ABS fails, wheels can lock up during braking, especially causing skids when turning. I recommend owners regularly maintain the sensor areas and inspect more frequently during rainy seasons. If issues arise, avoid long-distance driving and seek a professional shop for a thorough diagnosis—only drive after repairs are complete. Safety is paramount; skimping on minor repairs isn't worth the risk.
