As some of you have commented previously, my PHEV has a hard life - 40k miles a year from fast motorway, to mountain track and off-road.
I seem to be a 1 man system tester for Mitsubishi too, as previous issues have all resulted in extended technical assessments.
The latest was this week. On the steep decent between 2 Lakes District passes (no phone signal and lashing with rain at 6am of course) I got an RBS system failure warning on the dash and the vehicle immediately defaulted to safe move ie no acceleration, creeping forward in drive only. I pulled over, turned off and waited a few minutes, then restarted. The problem appeared to have gone, which was a relief as my only way out was via another 1:3 ascent. On the way back down exactly the same thing happened again, only this time, my on/off trick took longer to clear the fault.
Given my usage, the local dealer (absolutely brilliant as usual) took it in straight away. After a few days, though not certain yet, it would appear that water has ingressed to the battery compartment and on the steep decents has caused it to pool in an area which has triggered the problem. Not yet sure how the water has got in (though it has been very wet up here this week and we have had to navigate some man-size 'puddles').
As I said, great job by the dealer and technical team who have stripped out the whole of the battery pack, which is no mean task. What is great, despite not being able to recreate the problem under normal driving, they never once did the usual garage trick of 'can't find a problem mate'. Only down side is having a Skoda Octavia courtesy car!
