9/25/15 purchased brand new; already had 5 episodes of alert problem in tire pressure: 10/29/15 (2,835 miles) alert of tire pressure while driving at freeway & brought to dealer on same day:11/20/15, the lights went on again while driving at freeway: brought car to dealer on 11/21/15 4,536 miles- alert of tire pressure and brought to dealer; 12/28/15 (6,816)--made an oil change in same dealer and on 1/4/16 the alert signal was on again while driving on freeway and went back to dealer on 1/5--they didn't create a work order but checked the car and was advised and was shown by service advisor how to manually reset the alert so it goes away; called 1800-9991009 on 1/13/2016 @8:03 am and spoke with nikki and was advised to bring car back to dealer if lights go on again; on 2/29 the lights went on again while i was on freeway and thinking it was the same problem, i ignored it and went on driving until a passenger of a motorist signaled to me that there is something wrong with my tire--it was a flat tire. i exited freeway and parked in a safe area & called for roadside assist. on 3/1 (10888)car brought to dealer for a new tire. on 3/4/16 while driving on freeway, the light was back again and brought care to the dealer on 3/5 (111509). dealer recalibrated the sensors. on several occasions, i was told by various service advisors that the tire pressure should be exactly the same, not more, not less. i got a gauge to check it and in 3 out of the 5 events, my gauge showed the correct pressure and had other people validate it
