Opel Movano Engine Failed After Authorized Service Maintenance Error

My Opel Movano with license plate 34 P** 703 underwent its 20,000 km scheduled maintenance on 14.04.2026 at Çorlu Çetaş Opel Authorized Service.

Immediately after the maintenance, the vehicle began showing serious problems including heavy smoke emissions, excessive oil consumption, and major performance issues. On 21.04.2026, we took the vehicle back to the same service center, where we were told that the smoke was supposedly caused by residual oil left in the oil pan and that the issue had been “cleaned.” However, the problem was never actually resolved.

On 28.04.2026, the vehicle suffered a complete engine failure while driving and had to be transported back to Çetaş Opel by tow truck. Later, we were verbally informed that they suspected the injectors might be responsible.

Because we wanted the vehicle to be inspected by another authorized Opel service center, we did not approve any repairs there and instead took the vehicle on 07.05.2026 to Opel Erdemir Haramidere Authorized Service.

What happened there was even more shocking. The service advisor openly stated:

“Since Çetaş Opel worked on this vehicle, we cannot inspect it.”
“Take the vehicle away from here.”
“We accept no responsibility.”

During the preliminary inspection, we were verbally informed that the engine failure may have been caused by oil being filled into the wrong location during the maintenance performed at Çetaş Opel. However, the service refused to provide this assessment in writing and explicitly stated:

“We will absolutely not repair this vehicle.”

At this moment, our vehicle is completely unusable, and both authorized Opel service centers are refusing to take responsibility for the situation.

This is a commercial vehicle actively used for business operations. Because of this unresolved issue, we are suffering serious financial losses, business interruption, and significant damages.

The matter has even been personally escalated to Opel Turkey General Manager Mr. Y**** Y*****.

Our demands are clear:

An independent expert inspection must be conducted on the vehicle
All possible service errors and negligence must be thoroughly investigated
The vehicle should be evaluated as a defective product/service case
The vehicle should either be repurchased by Opel or replaced with a brand-new vehicle
All of our financial and operational damages must be fully compensated

Otherwise, we will proceed with all available legal actions, including material and moral compensation claims, and international complaint procedures involving Opel Germany and other relevant authorities.
