NHTSA Complaint #11557265 — 2021 JEEP WRANGLER

My Jeep has the 3.0 ecodiesel engine and there are two batteries. One battery is huge and powers all the components on my vehicle. The second battery is tiny and considered an auxiliary battery. It is located in a place that I can not get too, and can not check to see if its good or bad. However, as soon as it has any issues it will keep the Jeep from starting up. If you are out in the country or in the middle of nowhere then you will be stranded. It does not matter if the larger battery is working perfectly, the auxiliary battery will disable the entire vehicle anyway. This is a huge safety issue for obvious reasons. According to Jeep forums over the internet, this is a very common issue on all Jeeps with two batteries. It would be nice to take the auxiliary battery out, but Jeep engineered the two batteries to disable the entire vehicle if the auxiliary battery dies. Poor engineering? Perhaps! I would suggest there be a recall and that Jeep be forced to take the auxiliary battery out and re-wire the electrical system to allow vehicles to start regardless of the auxiliary battery. Some customers might want to keep the auxiliary battery cause it plays a part with the auto-start system. I would like to remove the battery and the auto-start all together and still have a functioning vehicle. I don't want to be stranded out in the middle of nowhere where I have no cellphone service.
