A few weeks ago, we got the news that the high-voltage battery pack (drive battery) will need to be replaced. In early-May, Baymax had thrown a check-engine light. This wasn’t entirely unusual – we’ve had check-engine lights on and off for at least a couple of years now. This time, investigation by Crowfoot Dodge failed to identify a specific fault, so back on the road we went. But two weeks later, the light was on again, and this time the car refused to accept a charge.
The latest setback comes just over a year after a battery pack control module software update had supposedly put one of the long-running Pacifica Hybrid battery faults – which we thought we had avoided – to bed.
Given the ongoing warranty issues and the regulatory climate in the USA, it’s no surprise that Stellantis dropped the Chrysler Pacifica Hybrid from the lineup at the end of 2025, along with its similarly powered, ‘4xe’ Jeep PHEV models. For more on this, I recommend you read this article from The Drive (once you’ve finished this blog post, of course!).
Otherwise, things have been thankfully quiet with the car since the last update in September. There was only one day this winter when the snow was deep enough to prevent the Pacifica from leaving the driveway (the long wheelbase and low ride height combine to leave it beached when the snow is especially deep).
Those days were further reminders of some of the benefits of the plug-in hybrid setup. It’s just a pity that Chrysler released something so flawed into the market to begin with.
Spring came very late to Calgary this year – we were still getting substantial dumps of snow in May – but on June 3, we finally had new tires fitted. It was clear last autumn that the outgoing Nexen N’Priz RH7as would not be going back onto Baymax in the spring, with the tread worn down almost to the warning markers and the shoulder area tread blocks starting to fray. By my calculations, the energy-saving Nexens have lasted for about 43,700km; they might have remained legal until 50,000km (31,000 miles), but I prefer not to run tires down to the bare minimum.
Versus the outgoing Hydra Edge Tour, the new MotoMasters promise better wet handling, grip, comfort and tread durability. In keeping with many recently introduced designs, staggered lugs in the tread pattern reduce road noise. Finally, the maker says that steering response is sharper thanks to a stronger cap ply.
After independent testing, Canadian Tire has installed it as its #1 all-season pick, assessing that it matches the best the tier one tire companies have to offer. Time will tell whether the Hydra Edge Plus lives up to these bold performance claims.
At the time of writing, I’m awaiting the arrival of the replacement pack. Once it’s in the car and we’ve covered some miles then I’ll report back on how things look in the brave new world of a (hopefully) fault-free hybrid system, as well as with an update on the new tires. Have a great summer and thanks for reading!
