I have filed for the lemon law replacement through Chrysler with no avail. I have not been contacted by anyone at Chrysler despite my repeated attempts at resolving this issue. Not only have I filed for the lemon law replacement within Chrysler, I have also filed complaints with the BBB of Michigan, the ky. Attorney general's office which referred me to the NHTSA due to the safety hazards that the cars tire pressure monitoring system displays when the vehicle is in use. Constantly while driving the system malfunctions. Chrysler has attempted repair for approximately 11 months and have ceased from communicating with me as a customer. I am requesting a formal inquiry by the NHTSA into the Chrysler corporation about this issue and their lack of communication to customers to resolve these issues. I have been inconvenienced for 11 months and at this time cardinal Chrysler louisville, ky. 502 449-1900 service manager charlie trya, has had my auto attempting repairs for 1, 1/2 months. Chrysler has replaced the tire sensors, the dashboard digital cluster, and the receiver for the tpm. Under the Kentucky and Michigan lemon law, my automobile should have already been replaced.

Thank you for your assistance in this matter. Chrysler is covering up major issues in their automobiles with the tire pressure monitoring system and misleading customers globally.

Tpm (tire pressure monitor) light keeps coming on, with a corresponding bell ring, every time I use the car and often again while driving. Dealer has spent countless hours and many visits attempting to repair same with no satisfactory results. A call to Chrysler's complaint line suggested that I inflate the tires with nitrogen! since the air is 78% nitrogen to begin with, I fail to see how that will help. In any event there is a problem here which seems to be a Chrysler fault that dealer can't resolve and the problem is ongoing.
