When we talk about Peugeot 308 SW reliability, we’re diving into more than just statistics and surveys. We’re asking a bigger question: Can this stylish French estate truly stand the test of time?

The Peugeot 308 SW isn’t just a stretched hatchback. It’s the practical sibling in the Peugeot 308 family—designed for families, long-distance drivers, and anyone who needs space without sacrificing flair.

But is it dependable? Or does it come with hidden gremlins beneath that elegant bodywork?

Let’s unpack everything.

Understanding the Peugeot 308 SW: A Quick Overview

Before we evaluate reliability, we need context.

The 308 SW (Station Wagon) has spanned multiple generations:

• T7 (2008–2013)
• T9 (2014–2021)
• P5 (2022–present)

Each generation brought significant improvements in build quality, technology, and drivetrain refinement. Reliability trends evolved with them.

What Do We Really Mean by “Reliability”?

Reliability isn’t just “does it start in the morning?”

We evaluate:

• Engine durability
• Transmission strength
• Electrical system stability
• Suspension longevity
• Maintenance costs
• Recurring faults
• Real-world ownership experiences

A reliable car isn’t perfect—it’s predictable. And predictability is gold.

First Generation 308 SW (2008–2013) Reliability

The early T7 models were ambitious but not flawless.

Common Issues We’ve Seen

• Electrical glitches
• EGR valve failures (diesel)
• Turbo issues on early THP petrol engines
• Timing chain tensioner problems
• Suspension wear

The 1.6 THP petrol engine, co-developed with BMW, gained a reputation for timing chain stretching if maintenance wasn’t meticulous.

Is It Still Worth Buying?

Yes—if:

• It has full service history
• Timing components were replaced
• Electrical systems are verified

These cars are affordable now, but diligence is key.

Second Generation (2014–2021): A Major Turning Point

This is where reliability dramatically improved.

Built on PSA’s EMP2 platform, the T9 308 SW shed weight and complexity. Lighter cars tend to stress components less—and that’s exactly what happened here.

Improved Build Quality

• Stronger suspension components
• Better rust protection
• More refined electronics
• Improved gearbox calibration

Engine Reliability Breakdown

Let’s dissect the heart of the matter.

1.2 PureTech Petrol Engines

The 1.2 PureTech three-cylinder became the volume seller.

Pros:

• Strong fuel economy
• Smooth for a 3-cylinder
• Affordable servicing

Concerns:

• Wet timing belt degradation
• Oil dilution (rare cases)

If serviced on schedule with correct oil, longevity can exceed 120,000–150,000 miles.

1.6 THP Petrol (Later Revisions)

Later updates resolved many early timing chain problems.

• Reliable if maintained
• Strong performance
• Avoid neglected early units

1.6 BlueHDi Diesel

One of the most dependable engines in the lineup.

• Strong fuel efficiency
• Durable turbo
• Solid long-distance performance

High-mileage examples routinely exceed 200,000 miles.

2.0 BlueHDi Diesel

The quiet workhorse.

• Excellent motorway durability
• Strong torque
• Reliable EAT6 automatic option

If you want the safest bet, this is it.

Transmission Reliability

The 308 SW offers:

• 5-speed manual
• 6-speed manual
• EAT6 automatic
• EAT8 automatic

Manual Gearboxes

Generally robust. Clutch wear depends on driving style.

EAT6 & EAT8 Automatics

The Aisin-sourced automatics are impressively durable. With fluid changes around 60,000 miles, they perform smoothly long-term.

Electrical System: The French Fear Factor?

Older Peugeots had reputations for electrical quirks. The 308 SW changed that narrative.

Common Minor Glitches:

• Infotainment freezes
• Sensor warnings
• Occasional parking sensor faults

These are usually software-related, not catastrophic failures.

Suspension and Chassis Durability

Estate cars carry weight—kids, luggage, bikes, the lot.

Areas to Watch:

• Rear suspension bushings
• Front lower control arms
• Drop links

Most components last 60,000–90,000 miles before replacement.

Not alarming—just normal wear.

Hybrid Reliability (P5 Generation)

The latest generation introduces plug-in hybrid options.

So far:

• Battery packs show strong durability
• Electric motors are low-maintenance
• Early reports are positive

Long-term data is still developing, but no major red flags yet.

Ownership Costs Over Time

Reliability ties directly to cost.

Typical Annual Maintenance Costs:

• Oil service: Moderate
• Brake pads: Average
• Timing belt (PureTech): Higher due to wet belt
• Diesel servicing: Reasonable

Compared to German rivals, parts are often cheaper.

High-Mileage 308 SW: What Happens After 100,000 Miles?

Here’s where we separate myth from reality.

A well-maintained 308 SW can:

• Reach 150,000+ miles
• Maintain structural integrity
• Retain drivetrain smoothness

Neglected examples? Different story.

Maintenance history is everything.

Peugeot 308 SW Reliability vs Competitors

Let’s stack it against rivals:

• Volkswagen Golf Estate
• Ford Focus Estate
• Skoda Octavia Estate
• Vauxhall Astra Sports Tourer

In recent years, the 308 SW sits comfortably mid-to-upper tier in reliability surveys.

It no longer lags behind.

Real Owner Experience: What We’ve Learned

Owners consistently report:

• Comfortable long-distance driving
• Solid motorway performance
• Reasonable repair frequency
• Few catastrophic failures

The biggest complaints revolve around:

More Caution:

• Early 2008–2011 petrol THP
• High-mileage neglected diesels

Is the Peugeot 308 SW Reliable for Families?

Absolutely.

It handles:

• School runs
• Road trips
• Heavy loads
• Daily commuting

Its chassis balance feels planted. Safe. Predictable.

That’s what families need.

Does Reliability Improve With Each Generation?

Yes. Dramatically.

• T7: Developing
• T9: Mature and dependable
• P5: Technologically advanced but promising

The reliability curve trends upward.

Long-Term Verdict: Should We Trust It?

The Peugeot 308 SW reliability story is no longer about skepticism.

It’s about intelligent ownership.

If you:

• Choose the right engine
• Follow service intervals
• Avoid neglected examples

You’ll likely enjoy years of dependable service.

It’s not bulletproof—but few cars are.

And it’s far more reliable than outdated stereotypes suggest.

Conclusion: The Balanced Truth

The Peugeot 308 SW has matured into a dependable estate car. Earlier generations had quirks, yes. But modern models—especially post-2017 versions—offer reassuring durability.

We wouldn’t hesitate to recommend a well-maintained example.

Reliability isn’t about perfection. It’s about consistency.

And in that regard, the 308 SW delivers.
