I Face Citroen C4 Turbo Failure After Authorized Service Said The Problem Was Fixed
On August 4, 2026, I took my Citroen C4 Shine 1.2 PureTech to the authorized Citroen Deniz Otomotiv service center for scheduled maintenance and repeated problems involving an “engine fault” warning, cruise control becoming disabled, and the radiator fan continuing to run for approximately 10 minutes even after the vehicle was turned off.
Although the service manager instructed the staff to connect the vehicle to the diagnostic computer at no additional charge because maintenance was already being performed, the service advisor did not include my fault complaint on the official work order. Instead, the system only stated that routine maintenance would be performed. I was charged approximately $278 for the maintenance.
The official service document I received states: “The vehicle was connected to the diagnostic device, reset was performed, the problem was resolved, and if it happens again, a detailed inspection will be carried out.” In addition, the Stellantis Free Vehicle Inspection Form marked all engine-area leak and inspection items as “acceptable” or in proper condition. Instead of identifying and permanently resolving what I consider a potentially serious safety-related fault, the service center simply cleared the fault code and told me that the issue was fixed and that I could continue driving.
I trusted the authorized service and left the facility. However, approximately 30 minutes later on the highway, the same problem returned more severely, the engine warning light came on, and the safety of my family and me was put at risk.
When I returned the vehicle to the same service center the following day, the same facility that had officially documented the engine as being in acceptable condition and stated that the problem had been resolved now told me that the vehicle had a turbo failure. I was then presented with a repair estimate of approximately $1,593.
Because of what I believe was inadequate service and contradictory documentation the previous day, I have already spent my available budget at this service center and am now experiencing significant financial and personal hardship. A turbo that was reported as being in proper condition and whose related fault was supposedly resolved should not fail immediately after the maintenance process without a thorough explanation.
I have already opened a complaint case with Citroen Turkey / Stellantis. I request that this matter be resolved urgently, that the serious service failure be addressed, and that the approximately $1,593 turbo repair be completed at no cost to me as a customer satisfaction remedy.
If this issue is not resolved, I intend to apply to the Consumer Arbitration Committee using the contradictory official service documents and the videos showing the vehicle malfunctioning on the highway as supporting evidence.
Progress
Citroen Deniz Automotive Defective Service On 04.08.2026 I took my Citroen C4 Shine 1.2 PureTech to the authorized Citroen Deniz Automotive service for periodic maintenance and for the repeatedly occurring complaints of "engine failure, cruise control deactivation and the radiator fan not turning off for 10 minutes while the vehicle is stopped." Despite the service manager's instruction to "the maintenance is already being performed, connect the vehicle to the computer without extra charge," the service advisor did not record my fault complaint on the official work order form and entered only "Maintenance to be performed" into the system. I was charged 13,250 TRY for the vehicle's maintenance. The official document of performed actions I received contains exactly the following statement: "Vehicle connected to the device, reset performed, problem resolved; in case of recurrence it will be examined in detail." In addition, the Stellantis Free Vehicle Inspection Form gave a "compliant" (solid) report for all leaks and control items in the engine section. Instead of solving this life‑threatening fault at its root, the service simply cleared the error code from the screen and told me "the problem is fixed, you can go on the road," sending me and my family away in a faulty vehicle. I left the service trusting them; however, on the highway the vehicle repeated the same fault more severely after half an hour, the engine warning light illuminated and our safety was jeopardized. The next day, when I took the vehicle back to the service, the same workshop that had marked the engine as "compliant" and said "problem resolved" on yesterday's official form now claimed a turbo failure and presented me with a cost of 76,000 TRY! Because of yesterday's shoddy service and irregular documentation, I have spent my entire budget on this service and I am now suffering a great financial and moral hardship. The turbo that was declared sound and repaired yesterday broke down again just ten minutes after the maintenance, and Citroen Deniz Automotive is fully responsible. I have opened a complaint file at the Citroen Turkey (Stellantis) level; however, I demand that the process be resolved urgently, that yesterday's severe service defect be compensated, and that this 76,000‑TRY turbo repair be performed free of charge as part of 100 % customer satisfaction. Otherwise, I will file a claim with the Consumer Court using the contradictory official service documents and highway breakdown videos in my possession.
Due to the technical inconvenience experienced after the maintenance at the authorized service of my 2021 Citroen C4, the complaint file I opened on this platform and with Stellantis Turkey has been resolved with a level of professionalism befitting the brand's global vision. I especially extend my infinite gratitude to Ms. Özlem, the Stellantis Turkey representative who has handled my case from the very beginning with great meticulousness, fairness, and sensitivity. Her constructive approach from the start of the process, the expert examination in her field that objectively clarified the technical details, and the customer satisfaction she provided have completely restored my confidence in Citroen and the Stellantis group. I thank Ms. Özlem and the entire Stellantis Turkey family for resolving the inconvenience I experienced in a short time with professional leadership, and wish them good work. I expect the same visionary and customer‑focused approach demonstrated by the General Directorate from the authorized Citroen Deniz Otomotiv service where I will collect my vehicle; I hope they will continue this positive process with delivery and service quality in the future.
