Introduction
A seven-seater carries the weight of a whole family's daily life, school runs, weekend trips, grandparents along for the ride, so it needs to actually work when it's asked to, not just look the part on the drive.
Unlike a smaller car used lightly, a seven-seater tends to be worked hard from day one, which is exactly why reliability matters more here than in almost any other class.
Reliability in this class isn't uniform either, and the evidence is worth knowing before you buy. The Hyundai Santa Fe is the standout seven-seater for reliability in 2026, achieving a 100% score in What Car's latest reliability survey.
Summary:
- The Peugeot 5008 isn't a car to avoid, but early examples fitted with the 1.2-litre PureTech engine carry a documented wet-belt reliability risk worth checking for specifically before buying.
- The Land Rover Discovery is genuinely capable but not genuinely reliable, a documented reputation for expensive, frequent repairs that's worth factoring into any purchase decision.
- Third-row space varies dramatically between models, some suit adults on a long journey, others are genuinely fine for children only, worth sitting in yourself before assuming any seven-seater fits your family.
- Families with multiple young children should check ISOFIX coverage and curtain airbag reach into the third row specifically, since neither is guaranteed across every seven-seater on this list.

What Else to Check Beyond Reliability
Reliability matters most, but a handful of other practical factors decide whether a seven-seater genuinely works for your family day to day, worth checking on any specific car before you commit.
What "usable" actually means. Not every seven-seater delivers seven genuinely usable seats. A usable third row fits adults comfortably for at least 30 minutes. A child-suitable one works for younger passengers but not adults. A token third row is really just extra boot space with an occasional emergency seat bolted in, worth keeping that distinction in mind against every car below.
Seating flexibility. Individual, sliding middle-row seats make it considerably easier to fit three child seats side by side than a fixed bench does, and third-row access matters more than people expect, some cars need the whole middle-row seat tipped forward, others offer a simpler one-touch fold that's far easier with a child already in a car seat elsewhere in the car.
ISOFIX coverage across rows. Not every seven-seater fits ISOFIX points in the third row, some only cover the second row's outer seats. If you've got multiple young children, check exactly which seats carry ISOFIX before assuming the whole car works for your family.
The boot space "dilemma." The real pain point isn't boot space with the third row folded down, it's what's left with all seven seats actually in use. Several capable seven-seaters shrink to barely any boot space at all in full occupancy, fine for seven people with hand luggage, genuinely impractical for a family holiday with cases and a pushchair. Check the specific seven-seat boot figure, not just the five-seat one manufacturers tend to lead with.
Curtain airbag coverage. An important, easy-to-miss safety detail: not every seven-seater extends its curtain airbags all the way back to the third row, leaving the passengers sitting furthest back with less protection in a side impact. Worth checking specifically rather than assuming coverage automatically extends the full length of the car.
Running costs and powertrain. With a heavy, fully loaded seven-seater, fuel economy takes a real hit, which is exactly why hybrid and plug-in hybrid options have become so popular in this class specifically, keeping school runs and daily commutes affordable even with the car regularly full. Check insurance group and tax banding too, since a large seven-seater can push into a noticeably higher bracket than the equivalent five-seat version of the same car.
Best Budget & Value 7-Seaters
Dacia Jogger
Standout feature: The most affordable seven-seater in this class, with surprisingly usable third-row space
Built more like an estate than a bulky SUV, the Jogger surprises with the amount of space in both the middle and third rows, and the rear seats are light and simple to remove entirely, opening up a considerable amount of load space.
Straightforward, affordable, and well-equipped even at entry level, if not built to win any awards for excitement. For a growing family on a tight budget, it's hard to match on space for the price.
Pros:
- The most affordable seven-seater in this class
- Surprisingly spacious third row for the price
- Simple, straightforward mechanicals keep running costs low
Cons:
- Interior quality trails SUV rivals in this class
- Fewer standard safety features on entry-level trims
SEAT Tarraco
Standout feature: Shares Volkswagen Group underpinnings with the Kodiaq at a meaningfully lower price
Built on the same MQB platform as the Kodiaq and Tiguan Allspace, the Tarraco typically undercuts the equivalent Kodiaq by a meaningful margin on the used market, though it hasn't been independently surveyed for reliability in the same way, so treat the shared platform and engines as a reasonable, if not conclusive, starting point for comparison.
The third row suits children and teenagers comfortably, and adults for shorter journeys.
Pros:
- Shares its platform and several engines with the Kodiaq, at a lower price
- Spacious boot with the third row folded
- Efficient mild-hybrid petrol option available
Cons:
- Third row noticeably tight for adults on longer journeys
- Boot space drops considerably with all seven seats in use
SEAT Alhambra
Standout feature: A value alternative to the Sharan, built on the same platform
Effectively the same car as the Volkswagen Sharan underneath, the Alhambra typically costs less to buy while offering the same clever, individually sliding middle-row seats and adult-usable third row. Even with all seven seats upright, it retains a genuinely useful amount of boot space, comparable to a small hatchback's full capacity.
Pros:
- Shares the Sharan's practicality and third-row space at a lower price
- Individually sliding middle-row seats make access noticeably easier
- Usable boot space even with all seven seats in use
Cons:
- Interior plastics feel less premium than the Volkswagen equivalent
- Less distinctive styling than some MPV rivals
Citroën Grand C4 SpaceTourer
Standout feature: A proper seven-seater that tends to sell for less than SUV rivals of similar practicality
Unlike several SUV rivals in this class, the Grand C4 SpaceTourer's third row is usable by adults on short-to-medium journeys, not just children, thanks to its MPV layout rather than a compromised SUV roofline. Its relative unpopularity against SUV rivals means used prices sit lower than the practicality actually justifies.
Pros:
- Usable third row for adults, not just children
- Strong value against SUV rivals of similar practicality
- Distinctive, spacious interior with a panoramic windscreen
Cons:
- Falls outside the more fashionable SUV body style many buyers now expect
- Diesel versions need the EGR valve checked on higher-mileage examples
Best Mid-Range & All-Rounder SUVs
Hyundai Santa Fe
Standout feature: Winner of What Car's 2026 seven-seater reliability survey, with a perfect 100% score
The Santa Fe didn't just perform well in What Car's 2026 reliability survey, it won outright with an unblemished 100% score, no owner reporting any fault at all over the survey period.
That's a rare result in a class that scored below average overall, and it pairs with one of the more usable third rows in this class, comfortable enough for adults rather than children only.
Pros:
- Won What Car's 2026 seven-seater reliability survey outright with a perfect score
- Third row comfortable for adults
- Efficient hybrid powertrain for mixed driving
Cons:
- Less engaging to drive than some SUV rivals
- Higher trims can push the price up considerably
Skoda Kodiaq
Standout feature: The diesel version is genuinely one of the strongest performers in What Car's 2026 survey
The Kodiaq has a solid general reputation, "the sensible-shoes champion" of the class according to independent reviewers, combining spaciousness with straightforward, well-proven Volkswagen Group mechanicals.
Worth being precise rather than just repeating the general reputation though: What Car's 2026 reliability survey names the diesel Kodiaq specifically among the class's most robust performers, a genuinely distinct result from the petrol version, which sits further down the same table.
Pros:
- Diesel version genuinely among the strongest performers in the class, per What Car's 2026 survey
- Spacious, well-built interior for the class
- Cheaper to buy and run than premium seven-seat rivals
Cons:
- Third row suits children more than adults on longer journeys
- Petrol version sits meaningfully behind the diesel on the same survey, worth checking which engine before assuming the reputation applies equally

Kia Sorento
Standout feature: Placed 7th of 12 cars in What Car's 2026 seven-seater reliability survey
The Sorento combines a solid, mid-table reliability result with a third row usable by adults, unlike several SUV rivals in this class. A plug-in hybrid version is also available, the only one in this class offering that specific powertrain option.
Pros:
- Third row suitable for adults, not just children
- Long, transferable manufacturer warranty
- Only seven-seater in this class with a plug-in hybrid option
Cons:
- Mid-table reliability result rather than a class leader, per What Car's 2026 survey
- Higher trims push the price close to premium rivals
Mercedes GLB
Standout feature: Named among the most robust performers in What Car's 2026 seven-seater reliability survey
The GLB was specifically named alongside the Santa Fe as one of the standout robust examples in a class that, taken as a whole, scores below average for reliability. Its third row suits children rather than adults on a longer journey, and its more compact footprint makes it easier to live with day to day than some larger rivals in this class.
Pros:
- Named among the most robust performers in What Car's 2026 survey
- More compact and easier to park than several larger rivals
- Wide Mercedes dealer network for servicing
Cons:
- Third row suits children rather than adults
- Smaller overall than most rivals in this class, with less boot space when all seven seats are in use
Nissan X-Trail
Standout feature: A distinctly modern package with semi-autonomous motorway driving as standard on higher trims
The X-Trail's e-Power hybrid system gives it electric-car-like driving characteristics around town, and its ProPilot driver assistance system, standard on higher trims, makes longer family journeys noticeably less tiring. As a newer model, it doesn't yet have the long-term reliability track record of some older rivals in this class.
Pros:
- Modern hybrid system with strong urban efficiency
- ProPilot assistance reduces driver fatigue on long journeys
- Third row suits children and smaller adults on shorter trips
Cons:
- Shorter reliability track record than more established rivals
- Boot space is compact with all seven seats in use
Ford Galaxy
Standout feature: A long-standing MPV with a well-earned reputation for trouble-free ownership
The Galaxy combines a spacious, comfortable interior with sliding doors that make loading children and car seats in tight parking spaces considerably easier than a conventional door ever could. Its third row is consistently rated more spacious than rival MPVs from the same era, and both the middle and rear rows slide and recline for real flexibility.
Pros:
- Widely reported as dependable, with few significant faults raised by owners
- Sliding doors make loading noticeably easier in tight spaces
- More spacious third row than most rival MPVs
Cons:
- Production ended in April 2023, so only used examples remain available
- Less badge appeal than SUV rivals despite comparable practicality
Volkswagen Sharan
Standout feature: ISOFIX points fitted across both the second and third rows
The Sharan pairs a roomy, well-finished cabin with sliding doors and a genuinely spacious boot even with all seven seats in use, reported to exceed a Golf's boot space with its rear seats folded.
Worth knowing honestly though: reliability has been reported as somewhat patchy compared to the closely related Ford Galaxy and SEAT Alhambra, so a thorough service history matters more here than on most rivals in this class.
Pros:
- ISOFIX fitted across both second and third rows
- Genuinely spacious boot even with all seven seats in use
- Refined, comfortable, car-like driving experience for a large MPV
Cons:
- Reliability has been reported as more inconsistent than closely related rivals
- Costs more to buy than the nearly identical SEAT Alhambra
Best Electric & Luxury 7-Seaters
Volvo XC90
Standout feature: A strong safety reputation paired with a properly premium interior
The XC90 combines a well-regarded reliability reputation with one of the nicest interiors in the class, alongside Volvo's consistently strong safety credentials. Both plug-in hybrid and mild-hybrid versions are available, giving real flexibility depending on your typical driving.
Pros:
- Strong safety reputation across independent testing
- Premium interior quality for the class
- PHEV and mild-hybrid options available
Cons:
- Engine range is more limited than some rivals
- New and nearly-new prices run considerably higher than mainstream rivals
Toyota Highlander
Standout feature: A highly regarded hybrid seven-seater with one of the more spacious third rows in this class
The Highlander combines Toyota's well-proven hybrid system with one of the more spacious third rows in this class, suitable for adults rather than children only on a longer journey.
Worth noting honestly: it doesn't currently appear in What Car's own UK seven-seater reliability survey, so its strong general reputation rests more on Toyota's broader hybrid track record than a directly comparable UK survey result against rivals like the Santa Fe or Sorento.
Pros:
- Backed by Toyota's broader, well-proven hybrid reliability track record
- Third row comfortable for adults, not just children
- Efficient, well-proven hybrid powertrain
Cons:
- Higher purchase price than several rivals in this class
- Boot space shrinks considerably with all seven seats in use
- Not directly comparable against rivals in What Car's UK reliability survey, since it isn't currently included
Kia EV9
Standout feature: Widely regarded as the best all-round electric seven-seater currently available in the UK
The EV9 offers a fully flat floor thanks to its dedicated electric platform, giving genuinely usable space across all three rows, and it's backed by Kia's substantial 7-year warranty, a real confidence signal on a still-maturing EV segment. It's a big, expensive car, but it delivers fast charging and a spacious, well-finished interior to match.
Pros:
- Genuinely spacious, flat-floored interior across all three rows
- Backed by Kia's 7-year warranty
- Fast charging supports longer family journeys
Cons:
- Not particularly quiet at higher motorway speeds
- Significant price premium over petrol and hybrid rivals
Mazda CX-80
Standout feature: A genuinely well-equipped newcomer, though too new to have appeared in What Car's reliability survey yet
The CX-80 hasn't been surveyed for reliability at all, so there's no direct evidence either way on this specific model, only Mazda's brand-wide position, mid-table, 16th of 31 manufacturers in the most recent full survey.
Reviewers genuinely disagree on third-row space too: some report adults fitting comfortably on a proper long-term test, while others describe it as cramped and only really suitable for children on shorter trips, worth sitting in yourself before assuming either verdict applies to how your family will actually use it.
Pros:
- Genuinely spacious middle row with sliding, reclining seats
- Boot space remains usable even with all seven seats in place
- PHEV battery backed by an 8-year, 100,000-mile warranty
Cons:
- No reliability survey data exists yet for this specific model
- Standard warranty is only 3 years/60,000 miles, shorter than Hyundai or Kia rivals
- Third-row space is genuinely disputed between reviewers, worth checking in person
Frequently Asked Questions
Do all seven-seaters have curtain airbags covering the third row?
No, and it's worth checking specifically rather than assuming. Some seven-seaters only extend curtain airbag coverage to the second row, leaving third-row passengers with less protection in a side impact.
Which seven-seater has the best reliability record?
The Hyundai Santa Fe currently has the strongest result in What Car's 2026 seven-seater reliability survey, achieving a 100% score. The Toyota Highlander is also highly regarded for reliability, though it isn't included in that UK survey, so treat its reputation as based on Toyota's broader hybrid track record rather than a directly comparable survey result.
Is the Skoda Kodiaq reliable?
The Kodiaq is generally a solid choice, but reliability varies by engine. What Car's 2026 survey puts the diesel version among the strongest performers in the seven-seater class, while the petrol version ranks lower.
Which seven-seaters have a third row genuinely suitable for adults?
The Toyota Highlander, Kia Sorento and Hyundai Santa Fe are consistently named among the few with third-row space adults can actually use on a longer journey, rather than children only.
Is the Peugeot 5008 reliable?
It isn't flagged as a weak performer in What Car's 2026 reliability survey, though early cars fitted with the 1.2-litre PureTech engine carry a documented wet-belt reliability risk worth checking for specifically before buying, regardless of the model's general reputation.
Is the Land Rover Discovery a reliable seven-seater?
It's capable and spacious, but it carries a well-documented reputation for expensive, frequent repairs, worth budgeting for seriously if you're considering one.
Conclusion
Reliability in this class isn't uniform, and the evidence matters more than badge or general reputation. The Hyundai Santa Fe stands apart with a perfect score in What Car's 2026 survey.
The Skoda Kodiaq's real strength depends on which engine you choose, and even a well-regarded model like the Peugeot 5008 deserves a closer look at its specific year and engine rather than a blanket verdict either way.
Third-row usability and boot space with all seven seats in use matter just as much day to day, so weigh the survey evidence against how your family will actually use the car before deciding. Whichever model suits your family best, every car at Car Planet comes with clear documentation and honest condition reports.
