5. Seat Tarraco (2018-present)

2019 Seat Tarraco front

Reliability Rating 87.5%

The Tarraco was plagued with issues, 33% of cars went wrong with complaints in a whopping nine categories: bodywork, engine, engine electrics, exhaust, fuel system, gearbox, interior trim and seats, non-engine electrics and sat-nav. 

Although all cars were still driveable, 42% took more than a week to repair. And even though most of the cars reported on would still have been under warranty, Seat only covered the cost of 83% of repairs, leaving the remaining 14% of owners with bills of up to £750.

Nearly half (44%) of the XC60s we were told about had issues, with the main areas of concern the air-con, bodywork, engine, exhaust and interior trim. Most cars were still driveable, but repairs were slow, with nearly 30% of stricken cars taking more than a week to put right. The only good news is that 94% of problems were fixed for free.
