My Honda Accord 2018 with 22,400 mi was NOT touched for a month as I was away on a trip. Come back drive it, and it drives well, but the next following day ALL the Warning Lights Flash on the Dashboard saying to see the Dealership. I take it to the Dealership. They ran a Diagnosis Machine for 3 hours.

They cleaned the Spark Plugs to see if would do stop the flashing. They then said the "Fuel Injectors" had to be Replaced. This took them 3-4 hours.

I really don't think they knew what they were doing. My car is still under their 10 year Warranty. This will be my last Honda I will ever buy.

Got my 2018 Honda Accord Sport back in Nov 2021 and it was perfect up until April 2022. I was heading to the store and soon as I got in all the warning lights came on. I freaked out like anyone would do, so I took it to my local dealer. They couldn't find the problem and I had no choice but to take it to nearest Honda dealership. At first they couldn't find any problem but wanted me to leave my vehicle until they could figure out the problem.

On day 3 they call me back finally telling me it's my fuel injector having issues. So I told them to check for other issues and the next day I got it back and it was fine. Then a few months later in June 2022, I got in my car to head to work and all the warning lights came back. I was like WTF at this point and called the Honda dealership back and explained that I was just there a few months ago for this same issue. They told me to bring it in and fixed the problem and I was good to go.

NOW it's a few more month later in August 2nd 2022 and I got in my car to go to the store and AGAIN the warning lights popped back. I was beyond pissed at this point. I used my OEMTOOL Digital Battery Analyzer to figure out the issue. The battery looked a little low so I took my wife's car to the local Auto Zone for a new battery. I ended up getting the 2nd most expensive battery to make sure this problem wouldn't happen again. I changed the battery and the warning lights came back on. I drove it for a quarter of a mile and came back home. I then turned my vehicle off and waited a few minutes, then turned it back on and all the warning lights were gone.

I'm still not convinced the problem won't go away permanently. It's also VERY frustrating to be worried every time I jump in my car that the warning lights will return, smfh! Honda, please fix this issue because it's becoming a MAJOR issue for all Honda owners.

Bought the vehicle as a certified pre owned in March of 2021. Has been a spectacular vehicle and is my 5th Honda. Went to Detroit for thanksgiving and the morning we were getting ready to head back to Ohio, it was very cold. Probably the coldest morning of the season (28°) cold started the vehicle and every warning light came up on the dash causing the safety systems to shut off. We were very aggravated at the time because we were 300 miles from home and it was a Sunday. Drove the vehicle home and hit the web to see what could be the problem. I Found a forum thread that stated it could be battery voltage being just low enough to short the electrical components. The battery seemed original to the car so I bought a new Honda battery from our local dealer and installed it myself. Once installed and started, some codes still appeared but quickly went away once I started driving. It’s been close to a month and have not seen any problems. Nobody seems to know what causes this root problem but the battery surely seemed to help it. I’ll be keeping and eye on it over the course of this winter to see if they come back but if not, I am certain this is linked to battery voltage.

Multiple lights (Brake System,Collision Mitigation System, LKAS, etc) all going off and after taking it into the dealer for these issues. It's continuing to happen except after a software update which they stated would fix the issue (not under HondaCare warranty for some reason). These lights continue to come up but now I have the added feature of my car randomly braking on me when I'm at highway speeds which is extremely dangerous. Taking it back to the dealer to see if they can roll back the software update.

Car has mind of its own... safe reliable lol. I'm afraid of it, just got car from dealership in July and it keeps having a melt down every light and warning light on out of nowhere!!! This is really what honda put me in with my children? This car isn't safe.

Update from Jun 24, 2021: So after 2 honda dealerships and over a week without car... it's normal get in back in January 2021 now June it's doing the same thing again! All warning lights on, and controls not working! Shame on honda this is getting ridiculous

Evening before problem started it was a heavy rain in NYC. Morning I started the car and was immediately received 4 messages: "LKAS: lane keeping assist system problem. See your dealer.", "road departure mitigation system problem. See your dealer.", "blind spot information system problem. See your dealer.", "auto high beam problem. Manual controls available. See your dealer.". Turn signals did not work. Hazard lights did not work. Trunk release did not work. Backup camera did not work. Moved to dealer (25 minutes away). But did not start the service. After turning off and start the car again all displayed failures were gone. Waiting for the next heavy rain.

I got into my car which I have had a little over a month and it has 1179 miles on it. I pressed the start button, no start. auxiliaries worked, couldn't get car out of gear. Pushed button on and off a few times to no avail. Stranded in parking lot, called hubby, he came, was perplexed and on a whim pushed the start button twice and it started up in limp mode. Error messages as follows: CROSSED OUT "D, POWER STEERING PROBLEM, EMISSION SYSTEM PROBLEM, ELECTRONIC PARKING BRAKE PROBLEM, HILL START ASSISTS PROBLEM, VEHICLE ASSIST STABILITY PROBLEM, LOW POWER to name a few.

I drove it home in limp mode and called the dealership, it was after 6 pm. I was told to have it towed in to them to check. That was after being bounced around 4x and having to call back to talk to someone for help. Next morning, I get in, start it up and no issue and no messages. I drove it to the dealership anyway because I didn't want this happening again especially since I will be traveling out of state. I will spare the bs with the service manager but long story short, they put the code reader on and couldn't find anything significant but showed there was lost connectivity (which to me is significant). they spent all of maybe 5 hours on it and did a reboot and told me it was ready and they couldn't find anything. Hubby called them and told them they should have spent a little more time getting to the root of the lost connectivity instead of taking the lazy way out and doing a reboot and hope for the best,and with no promise that it wasn't going to happen again.

I have read 2016 Civic Tourings have had this issue. Anyone have any thoughts? They kept the car a few days longer and checked the battery ground and cleaned something T1 or B1 (not sure what that is). p.s the battery was never an issue, it was perfect all along.....

I was driving on a side road (not a dirt, gravel, icy or snowy) and all of a sudden my dashboard lights up with 3 warnings. Adaptive cruise control, Forward collision mitigation system, Road departure avoidance system have been disabled and please contact the Honda dealer.

So I visit the dealer the next morning, and the service adviser tells me if the repair is not covered under warranty, I will be charged for the repair and if I chose not to repair, the diagnosis alone will cost me CAD 125/-. I asked what would make it not covered under warranty and she explains if I have had an accident and hit the radar damaging it. So knowing I haven't hit anything I said sure not a problem.

About an hour later, Honda dealership calls me saying that I have to pay CAD 320/- as the radar has physical damage and not covered. I tried my best to tell them I have not hit ANYTHING and this is not true. So she tell me that if ice or any debris hitting the radar while driving can damage the radar and this is not covered under Honda warranty. And they place this sensitive device right in front of the car and expect nothing to hit this???

I said I will call back and called Honda and they initially said this should be covered under warranty.And a few calls later back and forth between me, Honda and the dealer, it finally came back as environmental damage and NO IT IS NOT COVERED under WARRANTY.

So having no way out, I decide to get it done paying CAD 350/- (with the taxes) out of my pocket. So finally I get the invoice and what it says .. "Radar realignment" not replacement. So what physical damage was that? if the radar did not fail? So who says this is even physical damage? Who says I hit something ? no damage to my front bumper and how they came up with their diagnosis and tell me I did hit something is unacceptable.

My confidence on Honda is diminishing on daily basis ..

Purchased in May 2018 and noticed my brakes lights and Acc and other lights turn on and starts affecting my speed on the highway. I took it to Gillman Honda for a diagnose and they stated since I drive with two feet its normal. Now soon after that my taillight has a hole and I take it back to same dealer due to all lights on again. Now they say due to taillight broken that's why all my electrical lights on dashboard come on. It seems they are guessing and they are not wanting to help me. They reset code and check battery and just say all is good. My problem is still major issue and now I have noticed my brake light near rear window stays on while driving at night. Very dangerous and dealership doesn't assist.
