Dacia Sandero Headlight Fogging

Since purchasing my 2025 Dacia Sandero Stepway Extreme in March 2025, I have been experiencing persistent condensation in the front headlights. My vehicle has 11,000 km on it, and this issue has been present from the first day. The condensation becomes particularly noticeable in rainy and humid weather, and I am concerned that it may negatively affect driving safety. On March 12, 2026, I took my vehicle to the authorized Demireller Renault/Dacia service in Afyonkarahisar for its first maintenance and reported the headlight problem. The service informed me that all necessary tests regarding the headlights had been carried out, that the issue and the test results were recorded in their system, and that relevant photos and videos were also documented. Despite these official findings, Renault Mais headquarters initially refused to replace the headlights under warranty, citing “climatic conditions.” When I stated that this explanation was not technically reasonable, I was given another inconsistent and unconvincing explanation, this time claiming that the issue was caused by engine temperature. These contradictory statements, given while my vehicle is still under warranty and the problem has been clearly identified and recorded by the authorized service, indicate that the headlight condensation is a manufacturing or product-related defect and should be handled within warranty coverage. I do not accept being pushed out of warranty coverage or being delayed with inconsistent explanations. I request that Renault Mais take into account the records of the Afyonkarahisar Demireller Renault/Dacia service and replace the defective front headlight or headlights with new ones under warranty, free of charge, and provide a clear and concrete resolution to this issue without any further justification.
