The 1.2 PureTech engine, developed by the PSA Group (now Stellantis), has been a huge commercial success thanks to its fuel efficiency, good low-end torque, and brilliant performance for its displacement. However, beneath the surface lie technical issues that have caused numerous inconveniences for Italian drivers in recent years. Many users have complained of major breakdowns, even on cars with low mileage, which in some cases have resulted in significant repair costs. In this article, we analyze the most common problems, how to recognize them, prevent them, and address them effectively.

⚠️ COMMON 1.2 PURETECH ENGINE PROBLEMS
Premature wear of the timing belt (Euro 6B and 6C versions)
One of the most well-known defects of the 1.2 PureTech engine is the "oil bath" timing belt. Instead of running dry, this belt is immersed in engine oil to reduce friction. However, in many cases, the rubber tends to deteriorate prematurely, releasing residues that eventually clog the oil circuit and damage vital components like the oil pump or turbo.
Symptoms not to ignore:
-
Oil light on or low oil pressure
-
Abnormal noises at idle (metallic clicking)
-
Engine light comes on
-
Reduced performance or difficult starting
Excessive engine oil consumption
Numerous owners have reported abnormal oil consumption, in some cases as much as 1 liter per 1,000 km. The causes may be related to defective piston rings or a malfunctioning oil separator. Prolonged use with a low level can cause serious engine damage.

Turbo and injector problems
Urban driving, excessively long service intervals, or the use of dirty fuel can compromise the turbocharger's efficiency and lead to clogged injectors. The engine becomes uneven, loses power, and increases fuel consumption.
Problems with Gen3 releases (with chaining)
Starting in 2022, some models will be equipped with the new generation 1.2 PureTech engine with chain timing. Despite its improved durability, there have been reports of camshaft bolts loosening, causing the timing to slip. This can generate the following error codes:

🔧 PRACTICAL MAINTENANCE TIPS
To avoid unpleasant surprises and costly repairs, it is essential to follow some good practices:
-
Replace the timing belt at 60,000 km instead of waiting for the expected 100,000 km: better safe than sorry than sorry.
-
Check the oil level regularly , especially before long journeys. Use only high-quality oils with PSA specifications.
-
Clean the injectors periodically and use additives to clean the fuel system, especially if you travel many kilometers in the city.
-
Have your timing checked if you notice a loss of power or timing-related warning lights come on.
❌ COMMON MISTAKES TO AVOID
-
Ignoring official warnings from the parent company
-
Relying on non-specialized workshops for belt replacement
-
Underestimating symptoms such as metallic noise or loss of power
-
Using unsuitable cheap lubricants
❓ FAQ: FREQUENTLY ASKED QUESTIONS
Do all 1.2 PureTech engines have these problems?
No, not all of them, but the defects have been found recurringly on many models, especially those produced between 2014 and 2022.
How can I find out if my car is involved?
Check the vehicle identification number (VIN) at an official service center or check for active recall campaigns.
Is it safe to buy a used car with this engine?
Yes, but it's important to check the maintenance history, ask if the belt has been replaced, and check if the oil consumption is normal.
