Renault Arkana 1.3 TCe 160 Mk1

All 1.3 TCe 160 Arkanas come exclusively with the 7-speed EDC automatic, so this risk cannot be avoided by choosing a manual. Common symptoms include low-speed judder when manoeuvring, delayed engagement from a standstill, and a noticeable clunk when shifting between Drive and Reverse. The 160 hp variant delivers higher torque (270 Nm vs 240 Nm on the 140 hp), which can accelerate clutch wear in stop-and-go traffic. The clutch housing has been reported to crack along its factory weld, causing fluid leaks. Clutch pack replacement costs around 1,200-1,800 euros at a specialist. Full gearbox replacement at a Renault dealer can reach 2,500 euros or more. Regular gearbox fluid changes every 60,000 km help extend life. Software updates from Renault have improved shift quality on later production cars, particularly 2023 and later builds.

The 1.3 TCe H5Ht uses a complex plastic thermostat housing that is known to crack, typically at the dome joint on the upper section. When it fails, it tends to happen suddenly during motorway driving, dumping coolant rapidly. If the driver does not stop immediately, the resulting overheating can warp the cylinder head or damage the head gasket, pushing costs past 1,000 euros. The thermostat housing part costs around 80-100 euros, and labour is approximately 2-3 hours. Renault has released updated housing versions with improved material. Typically appears between 60,000 and 120,000 km. The higher output 160 hp tune may generate marginally more heat, though failure rates appear comparable to the 140 hp version. Check coolant level regularly and never overfill the expansion tank, as excess pressure accelerates housing failure.

The intercooler hoses on the 1.3 TCe are known to detach from their fittings due to inadequate factory clamping. The 160 hp variant runs higher boost pressure than the 140 hp, making this slightly more likely. Symptoms include a sudden and dramatic loss of power, often accompanied by limp mode and an EPC warning light. The fix is usually just refitting the hose and tightening the clamp, which costs almost nothing at a workshop. If the pipe has split or the turbo actuator has been strained, replacement of the hose or actuator inspection may be needed at 100-300 euros. Reinforced aftermarket silicone hoses are available for around 30-50 euros as a permanent prevention. Most commonly reported in the first 50,000 km.

The Arkana's OpenR Link infotainment system is prone to software glitches, including complete screen blackouts, frozen displays, and unresponsive touch input. Renault released a faulty software update that caused widespread unit failures, and replacement units were in short supply during the semiconductor shortage. In most cases, a software reset or dealer reflash resolves the issue. If the main board has failed (often due to sulphate accumulation on internal connections), the entire unit needs replacing at 500-800 euros. Reversing camera and parking sensor malfunctions are sometimes linked to the same infotainment control module. This is most common on 2021-2022 models and improved with later software versions.

All Euro 6d Arkana 1.3 TCe 160 models have a GPF that requires periodic regeneration at sustained higher speeds. Cars driven mainly in city traffic may not reach the exhaust temperatures needed for automatic regeneration. The 160 hp variant typically runs at slightly higher exhaust temperatures than the 140 hp, which can slightly reduce this risk during mixed driving. Symptoms include the check anti-pollution warning, increased fuel consumption, and eventually power limitation. A guided regeneration at a workshop costs 150-300 euros. If the filter is beyond cleaning, replacement costs 1,000-1,500 euros. Prevention is straightforward: drive at highway speeds for 20-30 minutes every 300-400 km of urban driving. Dirty spark plugs or worn injectors can also prevent successful regeneration.

As a direct-injection engine, the 1.3 TCe does not spray fuel over the intake valves, so carbon deposits build up gradually. This can cause rough idling, slight power loss, and increased fuel consumption, typically noticeable after 80,000-100,000 km. A walnut blasting or chemical carbon cleaning at a specialist costs 300-600 euros. This is common to all direct-injection engines and is not specific to the H5Ht, but worth monitoring on higher-mileage examples. Using quality fuel, regular highway driving, and occasional use of intake cleaning additives can slow the buildup.

Arkanas built between October 2019 and November 2021 were subject to recall 0DTM for faulty calibration of the electronic power steering computer. The issue causes overheating of an internal component during sustained steering input at full lock, leading to sudden loss of power assistance. Renault recalled 43,116 vehicles worldwide and issued a free software recalibration taking 30-45 minutes at any Renault dealer. If the recall has been completed, the issue is fully resolved at no cost. If the EPS unit has been damaged by repeated overheating before the fix was applied, replacement costs around 300-400 euros. This is a critical safety item to verify before purchase on pre-November 2021 cars.
