Hi Kpetrov, The dealer is making me feel like a madman. After they installed the new relay, the car worked perfectly until summer. We couldnt tell whether there was a problem over the summer because of no under 10 C temps. Come October however it was apparent that the car could not be forced into ev and the problem has only got worse with little to no ev use on trips up to 60 km.
This renders the car totally inefficient on trips to the gym or just into town.
The dealer can not decide what the story is; whether it was the relay or a software change. I contacted the mechanic today and he said it was done to protect the battery, but not having ev functionality below 10c ( he says 13c) renders the phev ability useless for half the year where we live.
In addition he said that they charge to balance the battery ( 280 dollars) . Our car has 65K on it and I would think that that would be a warranty issue on equipment that makes the car move.
The manual says that forcing into ev is a normal thing and MM Canada has removed basic functionality of the car.
What are your thoughts? Where can I read about the problem the other 6 car owners have had and why are there only 6 problems. The dealer says that I am the only customer having this problem.
So after the relay change the car was able to drive in EV mode even in cold temperatures? Did the problem emerged only the next winter?
Then it may have the battery state of health (capacity) set in to the parameters that govern the engine start-up as well.
I know of few owners that report this problem after a visit to the dealership for this recall. They confirmed that the vehicle is acting differently than before. Otherwise a lot more people are complaining regarding those unwanted ICE startups. Facebook PHEV groups are full of them.
Battery protection reasoning is dubious claim. All BEV are ruining in cold temperatures. Only the range and max current output is reduced.
They are doing it to protect the ICE from ignorant users and to maintain the advertised vehicle parameters or they may be liable for any sort of claims.
I have run my PHEV all winter with ICE disabled (relay removed) even in -20 Celsius. No problems at all. It is less powerful but at this temp. I am gentle on the accelerator. My battery degradation rate is no different than the summer one. Was warming properly the engine once per week or two on a longer trips.
