Some dealers care, others don't. My car stayed two weeks at the dealer to find a safari windows leak, until I took the car back, and I found the leak myself after some hours searching ... to hear later on that this was a known problem at Ineos Automotive.
Same with airco not working: was mentioned to them in June and only repaired end of August, when I didn't need it anymore!
I was very angry then on them, because I brought the car in at 8h00, they started only at 13h30 (found this by casualty) and couldn't finish the job (and other warranty tasks), and handed me the car only the next day, despite telling me that it would be finished in one day.
Now they told me that they will replace the airco filter next week, task included in the 20.000 km preventive maintenance: I refused that task!
I would like to go back to my Suzuki workshop: there was communication and service and honest explanation! I could walk in the workshop without restriction also! Official Suzuki dealer by the way!
