I feel awfully bad after reading this and I empathise with you.
When I sent my N Line for its first service to Universal Hyundai Najafgarh Service
Center, I too opted for a pick up and drop. Little did I know that the service center technician who drove that car would be takin git for a joyride. He was driving the car at highway speeds in a residential area.
Within Dwarka, on the route from my home to the service center, there is no place to drive the car over the speed limit of 50. The guy however crossed speeds of 90 kmph and 115 kmph to and fro respectively.
Service center manager was informed about this, but I’d hardly imagine they did anything. I should have made an official complaint.
Since day one, my car has had a rattle on the right driver door. I requested the service center to look into this during first service. They did, and someone broke the door trim itself, while trying to open it up. Pretty sure they observed it while the car was at the service center, but turned a blind eye. Only when I reported this issue a day later, they accepted the fault and ordered a replacement door trim at their expense. I appreciate that they accepted this and offered a resolution without fighting it out.
Coming back to the rattling issue, they sent a guy to check it out and while it was checked out multiple times, they could not agree that there was a problem in the first place. It took over an year and 3 dealerships to actually get this one sorted. During last service at Sapphire Hyundai Dwarka, it was identified that the door speaker was possibly faulty, but they suggested to visit their Mayapuri Service Center (about 9 kms away) and perform re-diagnosis.
I moved to Noida in December and finally, some time back at Karma Hyundai Sector 80, Noida the rattling issue was solved after the cause was identified as a combination of (possibly) faulty speaker and a plastic part: a bad washer. After replacing both of these things, the problem is solved. For the last few months before this replacement, I had stopped listening to music from the speakers because the rattle would creep in every time and spoil the experience.(Imagine the disappointment after spending so much on a car only to not be able to enjoy music due to faulty finishes)
Next, about 6-8 weeks into ownership, something in the Dash started making a weird sound on starting the car. Service manager identified it as a faulty AC actuator, which they replaced under warranty. In order to do that, they opened up the dashboard and steering column. After they fixed it back, in the following days and even the same day itself, I could feel my Car veering towards left, but the service technician disagreed. I showed and explained how it was happening but after no interest from the service technician or service manager to accept the existence of this problem I gave up on this conversation and left.
Few days later, I went there for a door change (I was sold a new vehicle with a repainted door from this dealership itself; it was another fight to get it fixed). I again complained about the left-veering on even straight roads and they ran alignment on the vehicle again. Nothing much showed up there and the car was visibly still moving towards the left in the following test run. The service engineer this time said that it is the road banking that is making the car seem like it’s moving to the left. Let me say this: I had visited that road numerous times in the past on this same vehicle and the car always maintained in the same line as the steering without fail.
Hopeless scenario, when you are not skilled enough to solve a problem, blame it on external factors. This finally got fixed when I took it for alignment a few weeks later to Manish Tyres, my nearby go-to for wheel alignment and balancing.
All this and after reading through numerous other reports of vehicular mis-use, similar to your vehicle and my own experience, I decided to spend as much time as it takes but stay with my vehicle every time it is serviced or goes to a service center any time any work is required. Once or twice every 6 months, I will take up that pain.
While it is painful to spend an entire day on this activity, it might be a better alternative to an accident/road incident/car damage resulting from their joyrides or their oversight. Because if there is an accident, it is your insurance they will ask you to claim on, and if there is a car damage in the workshop, they will most likely not accept it in the first place.
