Honda Elysion Multiple Brake System Failures, Need Help!

Hey there! I have some experience working on cars and went through something very similar with my 2014 Honda CR-V last year. The symptoms were almost identical, spongy brake pedal, warning lights, the works. Turned out my brake system wasn't properly bled after some routine maintenance. The mechanic had to perform a complete brake system bleed to get all the air out. Cost me around 90 Euro, but it fixed everything, all warning lights went off, and the brake pedal got its firmness back. Before jumping to conclusions about sensors though, Have you had any recent brake work done? Does the pedal feel worse when you first start driving? Are you losing any brake fluid? I've also known someone with an Odyssey who had similar issues, so it might be a common Honda thing. Let me know these details and I can better help point you in the right direction!

Thanks for the detailed response! Yeah, I've had my 2016 Elysion (293593 KM) serviced just two weeks ago, where they did routine brake maintenance. Now that you mention it, the pedal does feel particularly soft when I first start up, but seems to get a bit better after driving for a few minutes. Haven't noticed any brake fluid leaks under the car, though I'll definitely check more carefully now. Your experience with the brake bleeding issue sounds really similar to what I'm experiencing. Maybe they didn't bleed the system properly during my last service. I'll bring this up with my mechanic, sounds like a much simpler fix than replacing sensors! Really appreciate the help!

Hey again! So glad you provided those extra details about your Elysion. The symptoms you're describing, especially that soft pedal after startup that improves slightly with driving, are exactly what I experienced with my CR-V! You know what, the timing of your issues starting right after the service really makes me more confident it's an improper bleeding job. When I had my brake work done, the mechanic initially didn't get all the air out of the system, and it caused those exact same symptoms. The ABS and other warning lights come on because the system detects irregular pressure in the brake lines due to the air bubbles. Since you're not seeing any fluid leaks (which is good news!), I'd definitely start with getting the brake system properly bled before looking into sensor issues. When my mechanic did the second bleeding, he used a pressure bleeder and took his time to make sure all the air was out. Made a world of difference! Quick tip: When you take it back, make sure they bleed all four corners thoroughly and in the correct sequence. Some mechanics try to rush this job, but proper bleeding takes time to get all the air pockets out. Let me know how it goes, I'm really curious if your fix turns out to be as straightforward as mine was!

Here's how I would complete the conversation from's perspective: Thanks so much for the additional info and tips! You've really put my mind at ease. I just called my mechanic and explained everything, mentioning the possibility of air in the system from the recent service. They agreed it sounds like an incomplete bleeding job and can check it out tomorrow morning. I appreciate the tip about making sure they take their time with the bleeding process, I'll definitely mention that I want all four corners done properly. It's such a relief to know this might be a simple fix rather than an expensive sensor replacement! The similarities between your experience and mine are really reassuring. I'll update you once it's sorted. Thanks again for taking the time to help me troubleshoot this, you've saved me a lot of worry and potentially unnecessary repairs!
