Hybrids promise to deliver the convenience of a gas-powered engine with many of the benefits of an electric vehicle. There are several ways to build a hybrid powertrain, some use the electric motor to power the wheels, others use the gas engine, and then there are types that use both. Then you get mild hybrids (MHEV), which have a small battery and electric motor to assist the engine, and plug-in hybrids (PHEV), which have a more powerful motor and larger battery which needs external charging.
When done right, they make for a great all-rounder, and if your daily commute consists of lots of short trips, they can save you money at the pumps. Then, when you need to go on a long cross-country road trip, the gas engine steps in, and you don’t have to worry about range anxiety. However, the added complexity of a hybrid drivetrain often puts people off the idea of this type of vehicle, especially when it comes to plug-in hybrids.
So, we focused on this specific variant and did some research to find out which modern-day plug-in hybrids are the most reliable. Our rankings below were based on the latest findings by J.D.Power, and the vehicles are arranged in order of their quality and reliability scores, however we assessed them across all metrics to provide a more rounded comparison.
2025 Lexus RX 450h+
Lexus
Lexus
- Total Score: 81/100
- Quality & Reliability Score: 82/100
Toyota was one of the first manufacturers to successfully market a hybrid vehicle of any description, and its decades of knowledge in this area are clearly evident in the consistently high reliability ratings of its hybrids. When it comes to plug-in hybrid reliability, the Lexus RX 450h+ takes the top spot, maintaining the brand’s reputation for build consistency and long-term mechanical durability.
Its Dealership Experience rating of 85/100 is the highest on this list, reflecting a premium service standard, but the Driving Experience score of just 76/100 is the lowest in the premium category. This may be due to the engineers intentionally tuning the RX450h+ for isolation and comfort rather than sportiness, and owners mentioned the extreme quietness of the cabin (especially in EV mode) and the smooth, linear feel of the braking system as plus points. Perhaps Lexus knows its target market better than we thought.
However, something that irritated several owners was the complexity of setting up the infotainment and personalized driver profiles. The drivetrain comprises of a 2.5-liter four-cylinder engine paired with two electric motors. It is a tried and trusted layout and comes standard with all-wheel drive. As always, the Lexus remains a safe but staid choice.
2025 BMW X5 xDrive50e
- Total Score: 80/100
- Quality & Reliability Score: 81/100
The X5 xDrive50e is a big step up from the Lexus in terms of size and performance, and it offers a significant boost in electric range and power for the 2025 model year.
Perhaps unsurprisingly, it has a high Driving Experience score of 83/100, but you pay for the privilege with a low resale figure of 74/100. This is in line with other high-end European luxury vehicles but well below the figures for Lexus and Toyota models. While Hybrids promise great economy, the xDrive50e also delivers a serious performance punch, and owners liked the massive torque and acceleration from the hybrid system and the excellent hands-free highway driving assistance.
The lack of physical buttons for the climate control and the relative lack of comfort of the rear seats compared to the front were the most common negative comments, but the highlight of the package was the 3.0-liter turbocharged inline-six engine, which is highly regarded for its durability and performance.
2025 Jeep Grand Cherokee 4xe
Jeep
- Total Score: 81/100
- Quality & Reliability Score: 81/100
Matching the BMW’s quality and reliability score, the Grand Cherokee 4xe is also a standout for its ability to combine traditional rugged off-roading with an electrified powertrain. That off-road versatility also gave it high Driving Experience score, and owners appreciated the instant power of the electric motors and the refined, quiet cabin during city driving.
The size of this SUV was part of the reason why some owners found it difficult to maneuver in tight spaces and several were also disappointed by the fuel economy once the battery was depleted. Running a PHEV on the gas engine alone is always a recipe for high fuel consumption as you are lugging around the heavy electric drivetrain with none of the benefits. The Grand Cherokee 4xe uses a 2.0-liter turbocharged four-cylinder engine, which is not as powerful as the BMW’s power unit, but combined with the electric motor, it is more than enough for most. Consider the Anniversary or Base 4xe trims for the best reliable long-term choices because they can be configured without the complex electronic air suspension found on higher trims.
2025 Toyota RAV4 Prime
Toyota
- Total Score: 79/100
- Quality & Reliability Score: 77/100
The RAV4 Prime is the quickest and most powerful RAV4 ever made, though it is slightly lower on the reliability scale than most Toyotas due to minor tech-related complaints. Despite this, it dominates the Resale Value tables with an 88/100 score, which means it should depreciate less as a percentage of its initial purchase price over a 3-year period.
The 42-mile electric-only range and strong performance when merging onto highways were singled out by several owners, although the wind noise at high speed and a poor infotainment system were common complaints. You get one engine choice here, and it is an electrically assisted 2.5-liter inline-four that has proven itself across various Toyota products in the past. The SE trim is generally considered the most reliable choice, as it has the least amount of tech and features.
2025 Mitsubishi Outlander PHEV
2025 Mitsubishi
Mitsubishi
- Total Score: 78/100
- Quality & Reliability Score: 75/100
The Outlander is the value-conscious choice in the segment, offering a rare third-row seat for a compact SUV. It isn’t a particularly sporty vehicle, but it still scored a great 84/100 for Driving Experience, which is most likely due to its smooth ride quality, refined cabin and decent performance. All factors that this SUV’s target market appreciates. While its reliability score is the lowest here, it is still the fifth most reliable plug-in hybrid here, and the lower score is partly due to Mitsubishi’s smaller service network, so make sure you have one conveniently situated to where you live.
The excellent All-Wheel Drive (S-AWC) system’s performance in the snow was highly rated by owners, as was the overall value of the vehicle for the price. The cramped third row seating was less liked, and the infotainment system was also considered subpar on the base ES trim. All Outlander PHEVs use a 2.4-liter inline-four engine aided by two electric motors, and it has proven to be a reliable power unit. The SEL trim is the most popular and is recommended for its upgraded safety tech and driver-assist features.
While hybrids aren’t for everyone, if you pick the right type for your needs, whether it be MHEV or PHEV, you can benefit from the electric assistance and save on running costs. Just remember to always keep your batteries charged in a PHEV, otherwise you’ll be faced with worse economy and performance than a regular gas-powered car.
