What is normal for a 2018 PHEV with 75,000 miles on it, in the United States

[bobhedges]

Three months ago, I bought a 2018 Mitsubishi PHEV from a dealer in Fort Lauderdale. The unit appears to be in great shape. The tires look new, and the interior is spotless and shows no sign of wear. The CARFAX report indicates constant maintenance by the prior owner. Someone took good care of this car. Thanks.

When I gave the car its first overnight charge (off of a household 120 volt line), the next morning it indicated 12 miles of EV range. I have faithfully charged the car every night for three months with the supplied charging cable. I either charge at 8 amp or 12 amps. As time past, the EV range has increased from 12 miles to 15 miles following an evening charge.

I don't know if this EV range of 15 miles should be expected and is normal from a 6-year-old car. I know there is natural battery degradation, but how much is normal?

Should I take it to a dealer and request that the drive battery be worked on?

What should I ask for?

How much should that service cost?

What should I realistically expect?

What's been your experience in having your drive battery refreshed?

Love to hear your advice.

My 2018 PHEV with 95k miles got about 12 EV miles after overnight charge so it is normal for USA's version. I tried the dealer, they can't do anything about the degradation of the EV batteries & they even mention it in the USA manual. So don't waste your money & time. It is what it is. I tried all kind of methods in Youtube without any hope. For some reasons, the UK or Aussi's PHEV models got more EV miles. Mitsubishi programmed them differently.

Hi Bob,
That's a real shame.
What was the range showing on the dash display when you were inspecting the car, surely the most important check to make ?
Did the dealer say what range it had ?
Now that you've found this site you'll probably looked around and seen reference to the PHEV WatchDog software that would have told you the battery state before you bought the PHEV.
My 2014 still shows 28 miles range on a summer's day, though it has only done 35K miles.

Hi Guys, I have same model 2018 imported from US to EUROPE, we have now around 0 deg C temperature, and I have similar range on EV. At summer time it was around 20-22 mile, I am suprise how much rain decreases the range.

What is written above is 100% true. Dealers here are at least 2 decades back regarding PHEV systems technologies, they only focus on the ICE. I believe being illiterate has potentially nothing to do with their technical capabilities, it's just that they still proudly cling to the gas/petrol paradigm. Mitsubishi Dealers USA have been left behind by choice!
