Car bought new on 2014. On 2018 car started to show engine light to illuminate on and off. Jeep technician comply with recalls, and did not change transmission despite DTC U0402 was there all the time, and car was under warranty. Now, Delaware Motor Vehicle does not want to renew my tag because DTC U0402 is related to increase of emissions. Cost of changing transmission is $11,000. Jeep office does not want to authorize the change of transmission despite the problem started when the car was 4 years old. Not fair at all. I am worry to have accidents because of this DTC.
