Sounds like a battery issue but it's odd that it would restart easily. BCM could lead to shutdown of systems, the common one was the wipers though. I would have the recall done and have your starting and charging system checked. Thats the best place to start with something like this.

 

[Mr.2.g0]

Not if the cause was a loose terminal

True! I've suffered from a loose terminal or two in my day. I would go ahead and get the recall done regardless haha but yes, check your terminals.

 

[Mr.2.g0]

Could have been worse. Maybe a little peace of mind for you now.

 

[Mr.2.g0]

Yeah, I'd get it towed in without messing with anything at this point. It's losing power somewhere and its hard to tell if its electrical or mechanical. It seems to happen once you've been running at operating temps for a while so it makes me wonder if it isn't a faulty sensor somewhere that acts up when it gets too hot. Maybe a boost sensor problem. A turbo car won't start or stay running with a boost issue like that. Hard to tell with just the little information we have, but I'd be leaning toward something along those lines just due to the fact that its so intermittent and only happens when things have been at temperature for extended periods of time. Sorry for you luck, keep us updated with anything the dealer gives you. I'm really curious as to what you have going on...

 

[Mr.2.g0]

We had pretty hot and humid weather. Overheating wouldn't surprise me. on Saturday I was doing a curbside pickup that local Canadian Tire and my IAT was 170F.

Keep us posted on what the dealer finds.

How hot has it been up there? It makes me wonder if it is heat related if there is a major difference in cooling systems between a Canadian and US model. I've driven both my Si and Accord 2.0 through 100F+ ambient temp days in Texas with factor cooling on both the intake and radiator side of things.

 

[Mr.2.g0]

It was 34c outside and heat warning has been given for this week. Just that you know, I was driving in the same condition for 4.5 hours journey of 550kms ( roughly 300 miles) may be just one quick break to fill in gas...

Seems hot for up there. I recently took mine from central Texas down to the coast (200ish miles there, around town and 200ish miles back) and had zero issues. Rain, tons of humitidy and temps well over 90F (roughly what you had). Always possible it is overheating or like I said, an electrical issue brought on by excessive heat.

 

[Mr.2.g0]

Got to about 97F and very muggy. My car's intake temps were at 170F at a stand still, ended up turning the car off when not moving.

Heatsoak is real at those temps haha I can attest to that. I've never shut mine off even in traffic at 104+ but, again, makes me wonder if there are any major differences in the cooling systems between y'alls and mine. Interested to see what comes out of this. Hopefully whatever it is gets taken care of by Honda for the OP

 

[Mr.2.g0]

The number of electronic gadgets in these cars is my only concern with the car. Sometimes I want to sell it and pick up something older and less complex.

As somebody who came from the EG chassis primarily I have those thoughts all the time haha my favorite thing about my AP1 S2000 was how few electronics were on it when I went from a 93 Accord to that. The electronics are a gift and a curse...

 

[Mr.2.g0]

The car is under 7 year warranty. My hands are tied to take it to a proper mechanic. I don't trust dealerships but at this point I just don't have a choice.

Sadly, when it comes to warranty the dealer is the only option. Just have to let them do it and document it all.

 

[Mr.2.g0]

Update - The service reception guy just gave the keys and said it has been fixed. I asked what was fixed? (See attached). Apparently what they think is there was not enough pressure going into the fuel pump and they had readjusted fuel pupm everything. So when I started the car, I could hear a buzzing noise coming ( like flight taking off) from the fuel pump. I asked the technician to talk to me and explained, they are going to replace the fuel pump module.. I am not an expert but all what I can say is I am still not satisfied with their fix. so am still here.

That is definitely a fuel pressure code. Was your pump replaced under recall before this?

 

[Mr.2.g0]

Looking at the diagnostic flow ch

yes they replaced the fuel pump when they had the fuel pump recall last year. The latest recall that was performed last week was BCM that was irrelevant to
This issue.

Hard to believe the problem they're claiming from your pump took a year to show itself. Looking through the Honda diagnostic flowcharts seems to point to the direction of a fuel rail pressure sensor issue or a problem in the high pressure pump at the engine. I also don't have their live data to verify this with but what you have doesn't seem to be consistent with a lack of pressure on the low pressure (in the fuel tank) side of things.

 

[Mr.2.g0]

I just found this article. This is exactly the problem.

Honda Accord P0087: Fuel Rail/System Pressure → Too Low | Drivetrain Resource

P0087 is a relatively common OBD II trouble code. This code indicates that there is an issue with getting enough fuel pressure to the fuel rails. It's generic, which means that it has the same meaning for the Honda Accord as it would any other vehicle. This code is most common on vehicles that use

www.700r4transmissionhq.com

It seems like yours isnt throwing a pressure sensor code which probably leads to a fuel pump issue. I don't think they're taking their time to do a proper diag on your car. It is possible the fuel pump was installed incorrectly but I would want them to "correct" that issue and go further through their flow charts to make sure your issue isn't in the high pressure system.

 

[Mr.2.g0]

Could be as simple as they didn't clip the connection in all the way. But there are many thread about this now. Me thinks maybe the heat from turbo engine is maybe melting some of a harness or something could also be an issue........ meow!

Very well could be. Unless they aren't giving all the info it doesn't have a code to suggest the pressure sensor or injector failure. Possibly a loose connection? I'd be curious to see if they checked the main FI relay and its connections. OP is the fuel pump noise you're hearing coming from the rear or up in the engine bay? You should hear some noise from the HP pump up front but not quite like what you stated.

 

[Mr.2.g0]

Definitely keep us updated. I'm hoping you're good from here on though.

 

[Mr.2.g0]

Thanks for all your time and help trying to figure out the issue. I will definitely keep you guys posted. They said this is a common issue with their Honda line up. Not just Accord

No problem. Had some free time at work and was able to look up some of the repair procedures to try and get a better idea of what should be done/could be going on.
