"Is the Trezia 1.4D reliable, and what should you check?"
When buying a used Subaru Trezia 1.4D 2013, the most frequently mentioned issue is problematic DPF regenerations and soot buildup. Additionally, steering hydraulic failures are also commonly reported.
Engine: 1NDTV
1ND-TV · 1.4D · Used in this car from 2010-2014
Strengths
Very economical engine
Installed in many European models
Watch-outs
Many problems in early years
Not common on used market
Frequent oil consumption
Known engine issues
Recall campaignEarly diesel engines suffered from loss of tightness at the cylinder head and block joint. A large-scale recall campaign was conducted, and many of these engines were replaced under warranty.
Oil consumptionThe most common problem is oil consumption, usually caused not by wear of oil scraper rings or valve stem seals, but by turbocharger failure.
Oil leaksAnother weak point is the crankcase ventilation system, which quickly clogs, causing oil to enter the intake and leak from seals.
Listed from most frequently reported, each with its source.
Problematic DPF regenerations and soot buildup
Often reported
The 1.4D engine is sensitive to city driving and short trips: DPF regenerations may be incomplete or frequent, leading to increased smoke, temporary power loss, and risk of filter clogging.
Exhaust Emissions
Steering hydraulic failures reported
Often reported
Multiple user reports indicate intermittent steering hydraulic issues on Trezia models (2011-2014), ranging from loss of assistance to inconsistent steering behavior.
Steering
Robotic MMT Transmission: Jerky or Delayed Gear Changes
Often reported
The 1.4 diesel version was also offered with a 6-speed MMT robotic transmission; road tests report that this transmission may be less smooth than a manual or torque converter automatic, with slow or sometimes abrupt shifts, especially in city driving.
