2012 Vauxhall Antara 2.0L Diesel · WU12 THG

C4R's Antara buying guide lists DPF blockage with a fire-risk recall campaign as the headline fault on 2.2 CDTi cars: the DPF warning light comes on, usually on cars that only do short trips, because the filter self-cleans by burning off soot at high temperature and cannot do that on school runs. Under the recall Vauxhall first removed the lower engine compartment cover and later fitted a revised cover, with the DVSA recall record logged as R/2015/137. GetCarWise's Antara data puts professional DPF cleaning at £200-£400 and replacement above £2,000, with emissions-related warning lights running into the hundreds for diagnosis alone.

RAC's Antara (2011-2015) owner-report survey found electrical issues to be common, listing alarms going off arbitrarily, indicators not working, wiring loom problems, electric window motors burning out and ECU failures, alongside power steering failures and alloy wheel corrosion. C4R's Antara guide reports the same cluster from owner reviews - an alarm that triggers by itself, erratic indicators or central locking, burned-out window motors, failed boot locks or Bluetooth units - and explains that the cause is looms, connectors, motors and control units rather than one single part, so it must be traced with a scan tool rather than fixed by swapping components.

C4R's analysis of 2024 DVSA MOT data for the Antara found a fractured or broken coil spring recorded on 4.0 per cent of tests and an excessively worn suspension pin or bush on 5.2 per cent, with corroded springs flagged on 10.1 per cent of tests on 2007-2010 cars, and reports owners describing leaking struts - in one case both fronts at only 34,000 miles. GetCarWise's Antara fault data goes further on corrosion, quoting failure rates for suspension component damage and corrosion many times the fleet average with total repairs above £1,500 when several parts let go at once. Springs rust from the coating outwards, so a car can look fine and still snap a spring on a winter pothole.
