Summary

The Peugeot 508 is a medium-sized liftback and estate model. The current version was launched in 2018, and is considered a big step up from its predecessor. The liftback body style was launched first, with the SW (estate) versions arriving about six months afterwards.

The 508 has received a wider range of scores than usual from the UK media, ranging from average to outstanding. Particular praise has been given to its striking design, comfort and safety levels, while criticisms have been made regarding its driving experience and practicality compared to rivals.

A mid-life facelift for the Peugeot 508 arrived in the UK in late 2023. This is an update to the current model, rather than a significantly new vehicle. There are some minor styling and trim changes, along with some interior technology updates.

As of September 2025, the Peugeot 508 holds a New Car Expert Rating of C, with a score of 63%. It scores highly for its low average CO2 emissions (thanks to the plug-in hybrid). However, its safety rating and media review scores are only average, while running costs, the 508’s historic reliability record and Peugeot’s new car warranty coverage are all poor.

Notes on safety rating

The Peugeot 508 was tested by Euro NCAP back in 2018 and awarded a five-star rating. However, this rating expired in January 2025 and is no longer valid as the car no longer meets the standards required for such a rating. This is normal practice, as Euro NCAP reviews its ratings on most cars annually with most ratings expiring after about six or seven years.

Although the rating has now expired, the score is still useful if you are comparing a used 508 to vehicles of similar age – whose ratings will have probably also expired.

The Peugeot 508 is about average in terms of its running costs, according to five year cost numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.

The plug-in hybrid looks great on paper, but that’s due to the woeful EU/UK goverment lab tests that are completely useless at measuring a plug-in hybrid…

Reliability rating

MotorEasy logo 600x167

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

The Peugeot 508 has a reliability score that’s very worse than average, according to exclusive workshop and extended warranty data provided by our partners at MotorEasy. This score covers both the current-generation 508 and the original (pre-2018) version.

The average repair bill to date has been a bit over £600, although gearbox repairs have been very expensive with an average of almost £2,000.

If you’re looking at a used Peugeot 508, make sure any extended warranty cover you purchase covers all of these potential problem areas.

Warranty rating

New car warranty information for the Peugeot 508

Overall ratingD31%
Petrol or diesel modelsE17%
Electric or hybrid modelsC56%
New car warranty duration3 years
New car warranty mileage60,000 miles
Battery warranty duration8 years
Battery warranty mileage100,000 miles

Peugeot’s new car warranty is pretty much the bare minimum offered in the UK, with a duration of three years and a limit of 60,000 miles. Other rivals in the price bracket do better (and in some cases, much better).

In addition to the standard new car warranty, hybrid versions of the 508 have an eight-year/100,000-mile warranty for the battery components.

Warranty on a used Peugeot 508

  • If you are purchasing an ‘Approved Used’ 508 from an official Peugeot dealership, you will get a minimum six-month warranty included.
  • If you are buying a used 508 from an independent dealership, any warranty offered will vary and will probably be managed by a third-party warranty company.
  • If you are buying a used 508 from a private seller, there are no warranty protections beyond any remaining portion of the original new car warranty.

If you’re looking to buy a used car that is approaching the end of its warranty period, a used car warranty is usually a worthwhile investment. Check out The Car Expert’s guide to the best used car warranty providers, which will probably be cheaper than a warranty sold by a dealer.
