HI all,

we have a 2019 Odyssey Elite. Brought it in to the dealer last weekend for new brake pads and resurfacing, the OTA update for 3G disappearance, and a DVD player that's failing. Dealer fixed the brakes, performed the OTA update, and said that they did a full system reset to get the DVD player working. That did not work so they're now telling us we need a new DVD player (we have 80k miles so out of warranty).

Meanwhile, a few days after our dealership visit, we started getting bombarded with error messages.
  • Collision Mitigation
  • LKA
  • Adaptive cruise
  • Lane Departure Mitigation
  • Auto High Beam
Additionally, our proximity detection for the key not longer works and our nav system no longer has record of our "home" address (proof that they did a full system reset).

The dealer is telling us that it's a failure in the camera sensor and that we need a new camera. I don't believe it's a coincidence that the camera failed after service.

What diagnostic tools, service bulletins, other processes can I use to prove that the dealer needs to cover replacement (if it does indeed need to be replaced)?

Thanks in advance!

Update
Spoke to the service manager who relayed that the reset they performed was to disconnect and then reconnect the battery. Once the OTA update was completed, and the battery was reconnected there was a separate HondaSense OTA update. We think that's what caused the camera to stop communicating with the system. They ran full diagnostics this morning and received error code U3000-49 - "internal failure". I opened a case with Honda USA.

2019 Elite = the battery almost 3 years old. These Odysseys are hard on the battery. I would start with a non-dealer battery test at Autozone or Advance Auto type store (Napa, O'Riely etc) and see if the battery is good as the very first step.

Will go get it checked of course (and have been reading about similar problems in the forums: fuel injectors seem common, as does battery and grounding), however it's VERY suspect that we had no issues until after the dealer visit.

Even though this has been a common procedure since Gen 2, the reconnection to power can create a surge that can damage electronic components.

This is the perennial conundrum where a tech creates new problem B while trying to fix problem A.

Since the van is fairly new and you trusted its service to Honda, I think Honda should offer some goodwill to a loyal customer.

Hello, Did you ever fix this issue?

Hello @ewendkos. Would you mind sharing how this was resolved? I am experiencing the exact same problem (ACC, LKAS, etc.) and my local mechanic cited the U3000-49 code. Thank you!!!

Since 2019, I have replaced the battery twice, the amplifier, battery cooling fan and CPU. And yet, electrical problems continue. I noticed that problems are quieter in the winter, but flare up in the summer and often occur when the engine auto/stop triggers.

They told me the exact same thing, turns out the camera was fine and I bought a camera myself, the problem still there. I honestly think Honda is just trying to cop up some $ for those cameras and do something on the side to fix the issues.

The worst part is that Honda is extremely secretive about diagnostics, shop manuals etc. when you run a diagnostic on your own you end up with 100's of issues that may not be related.

This exact same issue exists with the Honda CRV. Same message exactly: The ACC, LKAS, Road Departure Mitigation, Collision Mitigation, Brake System, BRAKE Indicators and/or Auto High Beam Problem.


My local mechanic identified code U3000 49: internal camera software problem. This HAS to be the solution.

Fingers crossed this works (and the dealership is willing to do it.)

I am having the exact same problem (same 5 messages) as the OP on my 2018 Odyssey EX-L. Tried a 5 minute battery disconnect, no help. Got battery (1 year 2 months old) tested by auto parts store, voltage was a touch low (12.3V) but that shouldn't cause major issues like this.

However I did NOT have the issue when driving at night, nor in a parking garage. Maybe this is a clue, like it has to do with sunlight or heat? It's been in the low-mid 80s here.

I'd like as much info as I can on this, basically I don't want to take it to dealer and just have them say I need to replace both front sensors.

Honda told me I needed a new internal camera system. I said no thanks and sold the car. Like @tonyxl, there were ongoing electrical/technology flare ups anytime outside temp went up into 80s. Problems started after a dealer service visit at about 2 years old and just continued until now, 5 years old. This stuff will give serious ptsd! Not looking back! Good luck y’all!

Created an account just to say the same thing just happened to me, and also thank you posting this in the first place. Took my 2018 Odyssey in for an oil change and started it up and immediately saw these same warnings. Ended up with a ~$1300 quote for a new camera. I would have "asked to speak with your manager", but I didn't think it would be so much dang money when I looked at the quote. And now I'm seeing it may not even fix the issue. Any updates?

Just joined to get in on this one.
Same issues on my wife's 2019 EX-L. I'm not sure temp is a factor, we're in AZ and we spend a good amount of time above the 80's. We have found that sometimes if you start/off/start a few times it will work, don't get me wrong it's rare but I try sometimes on road trips just so I can use cruise control. We were quoted about the same money for the same fix, but haven't done anything about it. Honda needs to step up, some would see this as faulty safety equipment...

i've read enough around, that if you are getting the U3000-49 code (internal camera failure (or whatever)), for most people a camera change does seem to solve the problem. obviously, your mileage may vary. i'm pissed because this happened literally when i started up my car at the dealership after getting my oil changed, so it's obvious they did something to cause the failure. i've generally trusted these people in the past, so i don't think it was intentional. did the car wash short something out? was it simply disconnecting/reconnecting the battery that caused a short? is there software that simply needs re-installing? these are my questions. i have the warnings all the time thus far.

Ours (2018 EX-L) with 40k miles started doing this a couple months ago randomly. I've tried resetting the battery connection, checking grounds, and scanning/deleting all the codes in the computer (came up with the same code for the Camera). We didn't do anything car was wise or during any sort of hot weather in the area. My wife's ready to do the same (just sell/trade it in as is) and take the loss and move on to something possibly with a better track record. There's been A LOT of little things the van does that it shouldn't (I do get recalls, but this is past that). I'm 99% sure it's software releated as they just can't all die around the same time, but it would be nice for an over-the-air update that would fix it, or better yet Honda fixes it for free as it's a safety device and seemining is failing on a lot of models of their cars.

Mine started doing this a few weeks ago. I've disconnected the battery, given it a full charge, and I'm still getting the same alerts (brake, LKAS, ACC, and can't use cruise control). I'm seeing some are saying it's a software update and others are told they need a new camera. I'm at almost 80,000 miles but just noticed I'm covered with my HondaCare into next summer. Will report back how the local dealer addresses this...

Same problem mine is at 36K and started seeing this problem and at dealer today they saying to change the multi-purpose camera replacement for code U3000-49. With cost of $1,655.04 seems honda is riping customers. Any other suggestion to get this fixed ?
 
#20 ·
For what it's worth, I'll share what my local Honda dealer billed to HondaCare for fixing mine....

Labor - 1.8 hrs $230.99
Parts - $927.52
Tax - $67.25
Total - $1225.76

Also, I've seen a few locations online where the camera can be purchased for around $600, so I wonder if anyone may have luck buying the camera on their own and asking the dealer to install and configure in under 2 hours - I must assume HondaCare probably would not allow more than 2 hours of labor to install this.
