Highly disappointed with the service . Took my new car to get the weather stripping replaced (the vehicle is still under factory warranty), took 2 trips to get it looked at, get the new parts and replaced. Few days later on, we found that that the panel on the door is broken. I called up the service center and explained them that their mechanic opened up the door to fix weather stripping so he is the only one who broke it. I was asked to bring the vehicle back to the service center. Another trip back to the service center, and after 4 hours of waiting, they confirmed that their mechanic broke that while replacing the weather strip and now the part has to be ordered again..and they will call me again.. Waiting for the part to arrive...Not to mention, the wastage of my time (45 min drive each way to their service center).
