Buying a minivan built around hybrid technology promises lower fuel bills and quieter driving, but Consumer Reports’ ongoing reliability surveys suggest the electronics and powertrain behind that efficiency can also be where things go wrong most often. Among the model-year 2026 vehicles the organization currently rates least reliable, a plug-in hybrid minivan lands near the top of that unwelcome list.
Where the Pacifica Hybrid ranks and why
Consumer Reports’ published reliability guide gives the Chrysler Pacifica Hybrid a predicted reliability score of 26 out of 100, the highest score among the ten vehicles the organization currently flags as least reliable, meaning it is the “best of the worst” but still solidly in that bottom tier. The score is not a guess: it is built from survey data on roughly 380,000 vehicles reported directly by their owners, covering 20 distinct trouble areas ranging from minor annoyances like squeaky brakes to costly failures in the engine, transmission, EV battery and charging system. To generate a score, Consumer Reports requires at least two model years of data drawn from a vehicle’s three most recent model years, meaning the Pacifica Hybrid’s projection reflects a real pattern across multiple ownership years rather than a single bad batch.
What actually breaks
The Pacifica Hybrid’s trouble spots concentrate in exactly the systems that make it a hybrid in the first place. Its suspension and steering score well, and its road-test performance is strong, but the powertrain and in-vehicle electronics drag the overall rating down. Those two categories are also the most technically complex parts of any modern hybrid, which is part of why reliability researchers watch them closely: a failure in a plug-in hybrid’s battery-cooling system or its transmission tends to be both harder to diagnose and more expensive to fix than a mechanical issue in a purely gas-powered vehicle. The Pacifica Hybrid’s history includes two safety recalls tied to those same systems — a 2024 action covering roughly 24,000 minivans from 2017 through 2021 over a battery fire risk that led Chrysler to tell owners to stop charging the vehicles and avoid parking them near buildings, and a 2023 recall of more than 67,000 units after a short circuit was found to shut down engines during operation. The full breakdown of scores and trouble spots is available in Consumer Reports’ least-reliable-vehicles guide.
How Consumer Reports builds the full list
The Pacifica Hybrid is not alone. Consumer Reports’ current least-reliable ranking also includes the Honda Prologue and Chevrolet Blazer EV, both electric vehicles built on shared underlying platforms that have struggled with software and charging bugs; the Kia EV6 and EV9, both dogged by powertrain and battery-charging issues tied to prior recalls; the Mazda CX-90 and its plug-in hybrid variant, which share a turbocharged engine platform that has needed cylinder head and timing chain repairs; the Genesis GV60, weighed down by a string of drivetrain and electronics recalls; the Rivian R1T pickup; and the GMC Acadia, which the organization currently rates as the least reliable vehicle it tracks. Each score combines the owner-reported reliability data with results from Consumer Reports’ own track testing, a separate owner-satisfaction survey, and safety data, rather than resting on any single measure.
Consumer Reports’ rankings place the ten vehicles in a tight numerical band that runs from the Pacifica Hybrid’s 26 down to the GMC Acadia’s 14. The Honda Prologue and Kia EV6 each score 25, the Kia EV9 comes in at 24, the Mazda CX-90 at 23, the Genesis GV60 at 21, the Mazda CX-90 Plug-in Hybrid at 20, the Chevrolet Blazer EV at 19, and the Rivian R1T at 18, with the Acadia trailing the entire group. Autos editor Jon Linkov, with additional reporting from Steven Elek, prepared the ranking’s December 2025 update, presenting the models in order from least severe reliability risk to most severe.
Why hybrid and electric drivetrains complicate reliability
The pattern across nearly the entire list points to a broader shift in what breaks on a modern vehicle. Traditional trouble spots like brakes, transmissions and engines still matter, but battery packs, charging hardware, and the software that manages them have become new points of failure that did not exist on most vehicles a decade ago. A gas-engine transmission failure and a hybrid battery-cooling failure can both leave a vehicle undrivable, but the newer failure often involves proprietary electronics that only a dealer can diagnose, which tends to mean longer repair times and higher bills once a warranty runs out.
What the ranking means for shoppers
Consumer Reports frames its reliability data as a warning about total cost of ownership rather than a verdict on how a car drives or feels new. The Pacifica Hybrid, for instance, still earns praise for ride comfort and handling that keeps pace with class leaders like the Toyota Sienna and Honda Odyssey; its weakness shows up later, in the frequency of dealer visits once a vehicle is several years old and its factory warranty has expired. For buyers weighing a plug-in hybrid minivan against a conventional gas model, the ranking is less an argument against hybrid technology in general than a signal that this specific platform’s track record with its electronics and powertrain has yet to catch up with its fuel-economy advantages.
