Brand new 2019 Accord Sport 2.0 6MT with 350 miles on it and I get in yesterday morning and a message appears on the dash telling me that there is a problem with the Blindspot Information System and to take the car to a dealer. It had just snowed the night before and I wasn't exactly sure where the sensors were as I had snow on my rear deck that I didn't knock off completely.

No snow on the bumper (where I thought the sensors were) and the car was clean. Took it into my local dealer and they took 3 hours to pull a code from the BSI unit - Code U1297. Didn't tell me what it meant, but that they needed my car for "a couple of days to diagnose the issue" and then "another day or two to fix it." Having had the car for 9 days total, this was not a great answer. And to top it off, my local dealer would not give me a loaner since I didn't buy the car through them.

So not too thrilled with the car at the moment. Still runs great, just a PITA to have to deal with it. Another local dealer is going to take the car Monday and give me a loaner while they figure it out.

Sucks regarding your Blind Spot Info System failure. Unfortunately there are a lot of electronics on the X Generation Accord... w/bugs. Hopefully as more and more of these issues are brought to the attention of Honda they will be resolved and updates will be released that will eliminate the bugs from those not yet affected.

As for the dealer you didn't buy your car from not offering you a loaner when they wanted to keep your car they are an idiot... so what they lost the (one time) sale of the vehicle, now they've lost all the repeat service/parts/accessory sales from you... at least they would from me as I would never visit that dealership again.

Yeah, the electronics on this car are what scared me the most but I got the extended warranty to cover everything bumper to bumper for 7/100.

And yeah, my immediately local dealer is pretty terrible. They jacked the wheels up on my s2000 and they’ve never been responsive or helpful to any questions. I won’t be buying anything there anytime soon.

Now the Collision Mitigation System is telling me to BRAKE when nothing is in front of me (and when the weather is clear, mind you) and backlighting on the window and lock switches has started flashing at night.

Say hello to my Volkswagen Accord.

My guess is the snow caused your problem. Did it go away after the snow melted? I would think that if the sensor was blocked, it would simply light the light to show it thought a car was in your blind spot. But I think the sensors are smarter than that. I've put 6K miles on my car so far (2018 Sport 2.0 6MT). I have had maybe 3 times where the "BRAKE" light lit up when nothing was in front of me. I have found a few roads/examples where the sensors get confused. I think the Honda system is pretty good but not 100% perfect. We're still in 1st gen technology with this stuff. I have also had some slush spray from the road block the radar array in the lower front grill and I had to wipe it off to restore forward collission warning. The tach lit up the warning that the sensor was blocked so it was a 10 second fix.
Good luck!

Pretty common with Honda and Acura. Guess they dont test in the real world. My Acura brake warning would go off when I approach overpasses. Good thing it did not actually brake.

As for the other issue. A few weeks back all of those systems shut down after a 30 min drive in clear sunny weather. Pulled over, shut off car, and turned it back on. No issues since. So dont rush to the dealer.

I have even had false TPMS firings.

If this gets worse, this car will be sold. I am not a beta tester for Honda. These systems should work flawlessly.

Yeah, my issue has taken another turn... for the worse. Here's an update since my last post.

Not happy with the first dealer, I scheduled the appointment to take it to our other local dealer (we have three in the area). In between the time I was scheduled, my backlights on my door lock and window keys started flashing (both sides) like something was shorting.

Drop it off to dealer #2 last Monday (3/11). Tell them all the issues I was having. They give me a loaner and I'm on my way. They call me at 3 in the afternoon. They've determined they need to replace the BSI Sub-system radar unit. They also tell me they can't replicate the blinking backlights but they are going to do an ECU reset to see if that "fixes" the problem (you know, the problem they can't replicate but I could like clockwork).

Get a call the next day at 3. The car is ready to be picked up. Still couldn't replicate the blinking backlight, but the BSI system was now functional. Whatever... I'm happy its fixed and if the lights truly aren't flashing anymore... its a win.

Fast forward to today... 6 days after my car was dropped off and 5 days after the BSI system was repaired. I was driving home from the grocery store, and the BSI system alerts me that there is an error and I need to take my car to the dealer (same message as before). It was snowing earlier in the day, so I thought, again, maybe I had some snow build up. Got out, wiped off the bumpers... nothing. Turned the car on and off... same error. Oh, and guess what? The intermittent flashing backlights are back. So I'm thinking the two things are somehow connected (not sure how, but the lights weren't flashing before the BSI error message came back).

So it's back to the drawing board for me. I'm going to push for a lemon law replacement or refund. In Ohio, it's three times to repair on the same issue and this will technically be the second time, but all the dealer is doing is throwing parts at it.

Will update with whatever I hear from the servicing dealer. Also will call the dealer where I bought it to see what they say. Also might call Honda of America. This is getting stupid.

Good for you, but that's not the point. You pay for a car with certain features, you want to use those features. Not just turn them off.
Exactly... the option to turn features off because they don't function as designed is unacceptable... that's like paying for something and not receiving it. :sad:

The thing about saying,"if this electronics doesn't work good riddance I'll sell the car and get another one" has a major problem. All the other cars have this crap too. And likely it works even less dependably than Honda.


I have less than 1k on my 2019 and so far so good, but I do think I'll have to turn it off in really bad weather. If the turn it off function isn't broken too. I have a large number of doubts about whether these companies can put electronics on that will make the car last till 200,000 miles like they used to.

Where is the dealer you bought the car from in relation to the other two you've mentioned? Any new updates on the situation?
