Check a SEAT Exeo advert (free) →The SEAT Exeo has 2 known faults in our database, 1 of them rated high severity. The most serious are engine (timing chain tensioner failure causing engine destruction) and engine (EGR valve failure and DPF blockage following the 'Dieselgate' emissions software fix). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.
One owner each, in their own words rewritten as a line, and not counted in our risk scoring. A fault joins the list above once a second report or an editorial source backs it.
Sellers rarely admit these faults outright

They do not tell you whether this particular car has had the work: for that, put the registration into the free GOV.UK MOT history check, which shows a recall status where the manufacturer shares it, or ask a franchised dealer to check the VIN.
In some SEAT EXEO (3R) vehicles within the specified range of VINs with a front passenger airbag by Takata a deterioration of the propellant could occur due to high air humidity and temperature changes. As a result in the event of an accident and the activation of the front passenger airbag fragments of the generator housing could become detached and injure the passengers.
Put right by: The front passenger airgbag must be replaced.
Urgent Safety Warning - Do Not Drive Your Vehicle Issue: The front airbag in your SEAT vehicle contains an ageing inflator propellant that may explode when deployed due to long-term exposure to heat and humidity. Risk: If the airbag inflator explodes metal fragments may be ejected causing life-threatening or fatal injuries to anyone in the vehicle. Immediate Action Required: Stop driving your vehicle immediately. Contact the SEAT Takata Stop Drive helpline at 0113 526 9646 (Monday to Friday 9:00am to 5:00pm) to arrange your recall service. Mobility assistance is available if needed.
Put right by: For important safety reasons it is necessary to replace the inflator or driver/passenger seat's airbag module of your vehicle.
Takata has advised that in the event of an accident with airbag activation the front passenger airbag gas generator housing may explode. The cause may be a deterioration of the propellant caused by high air humidity and temperature changes during an extended period of time. In the event of an accident with front passenger airbag activation fragments from the gas generator can cause injuries and endanger the life of the passengers.
Put right by: Replace the passenger airbag as necessary.
Recall data published by the Driver and Vehicle Standards Agency under the Open Government Licence v3.0. A recall listed here may not apply to every car of this model: the build dates and the registration check are what decide it.
No SEAT Exeo year is a write-off, but the 3R (2009 to 2013) carries the most serious faults: engine. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for heavy oil use between services and engine management light. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against its known faults before you travel. Check a SEAT Exeo advert →

Recall work is done by the manufacturer, and GOV.UK says you will not usually have to pay for it.

Owners report 49.4 mpg on average across the SEAT Exeo engines with data, about 88% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 99 owner submissions. SEAT Exeo Real MPG by engine →
