2022 Accord Hybrid: ABS & VSA Lights On, Brakes Feel Weird

Vehicle: 2022 Honda Accord Hybrid EX-L

Hi everyone, I'm having a problem with my 2022 Honda Accord Hybrid EX-L. The ABS warning light and the VSA (Vehicle Stability Assist) warning light both came on simultaneously a few days ago and haven't turned off. They stay on from the moment I start the car.

I also feel like the brakes are acting a bit strange. Sometimes when I press the pedal, it feels a little spongy, and other times it feels like the car is trying to 'slip' or adjust itself even when I'm just braking normally. It's not consistent, but it's definitely concerning.

I tried turning the car off and on, but the lights persist. Has anyone experienced this with their newer Accord? What could be causing this, and is it safe to drive?

ClearTheCode admin answer:

When both the ABS and VSA warning lights illuminate on your 2022 Honda Accord Hybrid, it indicates a fault within the anti-lock braking system or the vehicle stability assist system. These systems are interconnected, so a fault in one often triggers a warning for the other. The strange brake feel further confirms an issue.

Possible Causes & Common OBD Codes:

  1. Wheel Speed Sensor Failure: This is the most common cause. Each wheel has a sensor that monitors its rotational speed. If a sensor is dirty, damaged, or faulty, the ABS/VSA module can't get accurate data, leading to system deactivation. Common OBD codes include: C1010-C1015 (Front Right Wheel Speed Sensor), C1020-C1025 (Front Left Wheel Speed Sensor), C1030-C1035 (Rear Right Wheel Speed Sensor), C1040-C1045 (Rear Left Wheel Speed Sensor).
  2. ABS Module Failure: Less common, but the ABS control module itself can fail. This is a more expensive repair. OBD codes might be in the C1000 range or specific to the module's internal fault.
  3. Low Brake Fluid: While usually triggering a separate brake warning light, extremely low fluid can sometimes affect ABS/VSA operation.
  4. Wiring Issues: Damaged wiring or connectors to the wheel speed sensors or ABS module can interrupt communication.
  5. Brake Light Switch: A faulty brake light switch can sometimes cause VSA issues, though usually not ABS.

What to Do:

  1. Check Brake Fluid: Ensure your brake fluid reservoir is at the correct level.
  2. Inspect Wheel Speed Sensors: If you're comfortable, visually inspect the wheel speed sensors and their wiring at each wheel for any obvious damage or debris. They are typically located near the brake calipers.
  3. Scan for Codes: The most crucial step is to get the vehicle scanned for diagnostic trouble codes (DTCs). A standard OBD-II scanner might not read ABS/VSA specific codes (C-codes), so you might need a more advanced scanner or a visit to a shop.

When to See a Shop:

  • Immediately. While your conventional brakes should still function, the ABS and VSA systems are crucial safety features that are currently disabled. This means you won't have anti-lock braking in an emergency stop, and the vehicle's stability control won't intervene if you lose traction. The 'slipping' sensation could be the system trying to self-diagnose or a partial failure. It's not safe to drive long distances or at high speeds with these lights on. A professional can quickly diagnose the specific C-code and recommend the correct repair.
