PHEV Flood Fail

Post by rhills » Wed, 27 Jun 2018, 22:33

Almost a year since our PHEV failed suddenly for no obvious reason, we had the same thing happen today, albeit with possible provocation this time.

We had 75mm rain (in our own rain gauge) overnight and so there were some very large puddles on the roads around our place. We headed off for our dental appointments this morning and waded through about 4 large puddles, none more than axle-deep About 2km past the last puddle we had a familiar cacophony of error messages on the dashboard. Basically every TLA (three-letter-acronym) our PHEV answered to was failing.

As happened last time, the vehicle dropped into "crawl" mode, I suspect this "crawl mode" limits the max current as acceleration was very sluggish, but we were able to get up to 40kph or so. We got back home, parked the PHEV in the garage and left it, heading out in our alternative vehicle, now very late for our dental appointments.

So, was it the water that triggered this problem? If not, it's a pretty amazing coincidence. We did some reading about the PHEV and fording and it appears that the official line is muddy. The manual makes some vague reference to not driving through water, however a number of people have stated online that they have been told that driving through water is OK, though various maximum depths have been quoted.

We've been extremely happy with our PHEV to date, despite the failure last year that resulted in a 6-week hiatus while the dealer struggled with the problem. Today's event has dented our confidence :-( We're not home tonight so the vehicle will have a long rest (and dry out hopefully) in its garage. However, what do we do if it starts up without any error messages as it did last year after "resting" for an hour or two?

Cheers,

I would say take this to the dealer with an eye to having it up on a hoist for very careful visual examination for missing or displaced seals around everything electronic. Also - mainly - check seals around sensors for ABS and any electrics around actual wheels.

If you're keen, check wheels yourself from under car. I have a PHEV to but haven't yet driven in heavy weather or any significant water.

We've been away from home since yesterday, with the PHEV left in the garage to dry out. Tried firing it up this evening and got the same alarms firing so I agree with you @Johny we'll need to get Mitsu to look at it. Dreading it though as the last time we had EV troubles we were without the vehicle for 6 weeks. As many others have found, Mitsubishi dealers seem to struggle with diagnosing/fixing their EVs. I also wonder whether something wasn't sealed properly after the work that was done last year...

My wife went through the manual and found a warning there that said "do not drive on flooded roads", whatever that means. To us, flooded roads are the ones where the water is over the bonnet like you get in the tropics, not glorified puddles. We drove around this evening to the spots where we'd driven through puddles the other day, none of the gutters is more than 150mm high and we don't recall seeing any nature strips covered with water.

I'll try and get a chance to have a look around the wheels on the weekend. When my wife rang Mitsubishi about it yesterday, they said to call out Roadside Assistance. We'll do that, but won't have the opportunity to do it during business hours until Tuesday.

I had a quick look and found. Couple of links indicating the outlander phew has a wading depth of 400mm.

Any chance of posting the links @HuffnPuff?

My wife came across a couple of mentions of 400mm in discussions in other forums, but I was driving at the time and wasn't able to confirm if they were authoritative or speculative comments. FWIW, a work colleague who has a Volvo SUV (non-electric of course, this is Australia!) had it clearly stated in her manual that the vehicle should not be driven in water depths greater than 40cm so it's obviously a figure specified by at least one manufacturer.

I know from an insurance point of view that if water enters the cabin over the sill then the car is a statutory write off. If you take into account the bow wave while driving through water then 400mm is a reasonable figure to give to those who can't figure it out themselves. Easy disclaimer.
I wish I could find where I got the following but I remember when converting the Vogue that I had to insure that the vehicle could handle 200mm of water safely.

I remember hearing a figure of six inches being all it takes to flood a vehicle. Some very brief research says 6"/15cm is about the threshold for a small car, while larger and heavier cars can tolerate maybe 45cm (give or take, depending on the make/model); this is based on actual testing, not just models or manufacturer warnings. If it is over the bonnet, that's enough to get nearly anything floating or drowning.

Sorry, was just a quick google search. After your post I wondered wether there was a manufactures listing on wading depth. After all, the outlander is an suv and usually advertised off the beaten track.

Mitsubishi do test there EV's through standing water. As you can see in the link bellow they test the imiev with the battery fully under waterhttps://insideevs.com/wp-content/uploads/2013/07/14.jpg
