trollllllI traded in my 2014 JK and bought a new 2019 JL Sahara in December 2019. Only 3 weeks after the purchase, I saw a lot of issues with this brand new JL:
1. check engine light came on, with code U0074
2. battery warning light came on, showing low voltage
3. auto start/stop warning light came on, the vehicle could not start after it was auto off
4. most dangerous problem: the steering wheel lost power when I was exiting the highway. I had to turn the wheel very hard to exit the highway, and suddenly the steering power was back and I nearly had an accident. This steering problem happened nearly every one minute 2 days later on my way to the dealership for diagnostic.
And one thing I am not sure if it is normal or an issue: the ETC light came on after I started the vehicle, but it disappeared very quickly.
The vehicle is now in dealership for diagnostic. I filed a claim in Chrysler's customer service website, and they contacted me saying they are reviewing my case. I will update the post when I get response from dealership or Chrysler.
