Seeking Advice on 2021 Lexus RC Hybrid's ABS Warning Issues and Error Faults

Hey! I feel your pain, had a similar issue with my 2018 Lexus ES Hybrid a while back. The old girl started showing up an irritating ABS warning light just like in your case. And yeah, ABS/DSC system not responding at all, absolute nightmare! And mind you, it wasn't a small issue. Turned out, my ABS control unit was defecting. Same scenario - odd warning light in the speedometer and the computer storing a fault. So, your hunch about the faulty speed signal might be off. As for the visit to the mechanic shop, well, it wasn't pleasant but what can you do? You've got to bite the bullet. My experience though was relatively chill. The lads did their job well, they ran a series of tests and managed to diagnose the real issue. Took a bit of time to fix but mainly because I wanted to thoroughly understand the process. In the end, they got her back in gear and I haven't experienced any problems since then. So don't fret too much. It sounds like you're looking at a similar malfunction. Not sure about your garage trust issues, but it's not something you can fix yourself unless you're an expert. Choose a well-reviewed garage, and keep your fingers crossed. Cheers!

What's up, partner? Wow, those lights must be driving you nuts! Sounds a lot like what had with his ride. So, it might be that irksome ABS control unit giving you all that grief. As much as we'd love to dodge those mechanic visits, they're pretty unavoidable for this kind of thing, ain't they? Your Lexus ain't old, but if it is indeed that ABS unit, then that's a problem that can't really be bypassed without some professional expertise. Your best bet would be to pop into a decent garage (with good reviews, of course) and hope for the best. By the way, would you mind sharin' what kinda dent the fix put in your wallet? I'd guess the cost varies, but it'd be good to have a ballpark figure. And since you've had your ES fixed, has anything else wobbly popped up related to this? Cheers, lads!

Hey there, Definitely agree with you, getting those defects rectified by a professional is a must. Our beloved Lexus ain't exactly the easiest gal to tinker with, yeah? But to answer your question, fixing my ABS issue required some serious dough. Shelled out about 1000€ for the whole affair. Not that great for my wallet, but hey, at least it was fixed properly! And since you asked, nothing else shaky has crept up since the fix. My initial take on the speed signal turned out to be quite off the mark - the mechanic set that straight. No more annoying warning lights or anything of the sort. The lads did a solid job, and the car's been as good as gold since then. Hope this helps! Brace yourself if you decide to take your ride in, it ain't cheap. But worth it to get your vehicle back in tip-top shape. Cheers!

Hey again, I really appreciate the in-depth responses, you've given me plenty to mull over. The consensus points towards that pesky ABS unit — I bet you're right. As much as I was hoping for a DIY quick fix, it's clear this isn't one of those times. Ugh! That 1000€ cost, though! Makes me gulp a bit, won't lie. But as you've well noted, I could do worse than a well-reviewed garage. I would rather shell out the Euro to get her back in top condition than risk further problems. I'm aligned on your points; I reckon it's time to put my trust back into a mechanic. I'm not too eager, but I've gotta do what's necessary. And hey, cheers for the specific warning about incorrectly diagnosing a speed signal fault - extremely useful, that. I'll be setting an appointment in the coming days. Thanks a bunch lads. Your feedback was super helpful. Let's hope for a smooth process like yours. It was reassuring to hear your girl's been running smooth since. Wish me luck, and keep those gears grinding! Cheers boys!
