Took my car to DRS motors, gurgaon on saturday. The service advisor had called up a person who new about this seat issue. This confident looking chap told me he has solved such issues in 3cars before and the earlier batches had this issue of squeaking seats. May be the springs in the seat back need correction. After some diagnosis both front seats were opened up. All springs of seat back were checked, no noises from springs. Some alignment issue was there in seat rails as the teeth were not setting up properly, corrected. Bolts at the hinge were opened, no sign of wear and tear. Everything cleaned up, greased and fixed back. Surprisingly, 90% of the noise is gone. only a very faint squeaking noise comes. Its like seat covers making some noise. They again took out the seat and found the bolt holding seat belt was making this noise. Bolt was ok it was cleaned lubricated and put back. Absolutely no noise now.. Took multiple test drives, on all types of roads. No noise.. car is noise free uptill now..keeping my fingers crossed. I checked each and every car in the service center for this noise. to my surprise all of them were making noises at different places, no new linea or evo were there. Seems like people are enjoying their upgraded ICE.
