Bit of a saga coming up. Bought the PHEV two weeks ago from a branch in Milton Keynes, UK. 2 years old, 10,000 on the clock. I thought what could go wrong. Had two weeks of joy with it, really is a spaceship to drive compared to the old Alhambra. Got the charge point installed already on the house, so all good to go. Run it for about 300 miles so far in "EV" mode, only ran short on battery twice, so the ICE has done about 10 miles for us in all.
Wife went to fire it up last night and we got a whole myriad of issues come up on the dash, listed below.
EV system service required stop safely
Brake system service required
ASC system service required
BSW service required
The start/Stop button wouldn't turn off the car, it screamed if I left with the key, the drivers window wound down but wouldn't go up. The front passenger window worked and the rear driver side, the rear left wouldn't work. the boot would open but not shut and it wouldn't lock.
Called the dealership, they put me on to their service department, the technician there asked if I could call my insurance company to get the car towed to them. Not mega impressed with that TBH.
Had MAP cover (cant remember the acronym but its Mitsubishi breakdown cover for new owners), called them at 3:30Pm and they said they'd get the AA out to have a look and see if they could fix it, if not they'd get it towed back to the garage and give me a courtesy car (whole other thing, they'd give me the hire car if I paid for the insurance, at £10 a day!).
Thought the issue must be electrical, no way all that stuff just went wrong sat idle on the drive. Checked the AUX 12V battery in the boot, it's reading 8v, not good.
Called the garage's service lot again, explained it to them, and they said "well it's a dead battery". I asked if it could be an issue with the DC-DC converter, or if the car even had one to charge the 12v lead acid battery from the lithium system. he said
"nope, the car always starts the ICE for a few mins every time you run it".
So I called BS as I know what it sounds like when it runs the ICE and we hadn't been using it, fuel range hasn't gone down since we got it, save for the two times we ran out of EV range.
I'll summarize a little here, the AA never show, the hire car never shows, the recovery lot call me and say they wont get to me then the garage before they shut, so they'll come in the morning. So I'm left with the cruel irony of having to jump start my electric car with my work van so I can lock it.
Car gets recovered, recovery guy mentions he checked the battery under the bonnet (didn't know it had two 12v lead batteries) and that's reading 8v too. Dealer who sold it to us speaks to the wife in the morning and says he'll call back in an hour with an update. Nothing. I then call back at 3 Pm and he says the same. I then call back at 4:50 Pm (10 mins before they shut) and he says "I'm not sure if it's come in yet". So he puts me on to the service team. They confidently start the following dialogue:
Them - "It's here and we've had a look, the battery needs replacing"
Me - "Ok, which one"
Them - "what do you mean"
Me - "There's three batteries, which one needs replacing?"
Them - "The 12 volt one sir"
Me - "Great...WHICH ONE?!"
-more background mumbling-
Them - "The one in the boot"
Me - "Ok, so whats wrong with the one in the front? That was reading a low voltage too"
Them - "Just the one in the back sir, should be ready Friday"
-conversation quickly tails off as it's clearly approaching quitting time-
So I guess my questions to the hive mind on here;
Is it a two year old 12v lead acid battery? which are legendarily reliable.
Is it possible the front one is fine despite a similar low voltage?
Does the ICE always, or even occasionally run on first startup (which I've never heard) or is there a problem with mine there? Bearing in mind our standard startup procedure is hit the start button, hit the "EV" mode button, stick it in drive and go (without driving like a hooligan, I know if you boot it, even in "EV" mode, the ICE will start for extra punch).
Could it be an issue with a DC-DC converter that is supposed to charge the 12V batteries when plugged into the wall, which may explain why both front and rear 12v batteries are reading low voltages? Or have I made that system up in my head and they can only be charged via the ICE which I will have to use periodically to charge the 12v batteries?
Thanks for taking the time to read through! Little concerned the dealerships in house mechanics are talking out of their ass, trying to get a sense check and some more info on the car. Bit frustrated with the whole experience really.
