2022 Jeep Wrangler: battery drain or dead battery

Filed Sep 16, 2026 · Electrical, Transmission · IL

I am submitting this complaint regarding a critical electrical issue and potential safety hazard that occurred immediately after the 68C safety recall software update was performed. Since the 68C recall completion, my vehicle has experienced significant overnight High Voltage (HV) battery drain, losing approximately 10% of its state of charge while parked and powered off. I have returned the vehicle to the dealership three times for diagnostic testing. On the most recent visit, the dealership, working with Jeep engineers, claimed that the radio system fails to sleep, causing a continuous power draw from the battery. However, the dealership and Jeep engineer attributed this failure to a dash cam plugged into the factory 12V auxiliary power outlet (cigarette lighter socket). I believe this diagnosis is technically flawed and incorrect: The factory 12V outlet is off when the vehicle is powered down, meaning no current is drawn by the accessory once parked. The dash cam has been in continuous use since I purchased the vehicle without any issues; this battery drain issue began exclusively after the 68C software update. Blaming standard user accessories for the infotainment system's failure to enter sleep is unacceptable and ignores a likely software bug introduced by the 68C update. If the vehicle's electrical control modules fail to power down properly overnight, it poses unpredictable electrical and thermal risks. I escalated this issue to an FCA Case Manager, who upheld the engineer's assessment without addressing the underlying software defect. FCA has failed to perform due diligence in resolving this issue.

When driving the vehicle down the highway it just randomly hard shifted out of know where almost causing us to be rear-ended. The dash then said service transmission continue in drive do not shift or turn engine off until you reach a desired location. You may not be able to shift again until services. It then limited power to the vehicle. It was show codes U1003, U0101, and U0402 multiple times. The vehicle was taking to a dealer where it was "parked" only it wouldn't go into park. We had to put the e-brake up holding it in place at the dealer so it wouldn't roll. Then when attempting to shut the vehicle off it only stopped the engine from running. It stayed in ACC mode all night until the dealer could mess with it the next day. The dealer is now saying it's just a dead battery. This is unsafe and could have ended very badly just for a dead battery that showed no signs of issues before hand. For a vehicle that on has approximately 57k miles and is 4 years old this is horrible.

On 2/2/26 I took my vehicle to Thomson Motor Company to have the 68c recall repair completed. On 2/5/26 my car wouldn’t start and I was stranded. My vehicle was towed back to the same repair facility. On 2/6/26 they told me that my regular battery died and had to be replaced. After researching when the hybrid battery is re-coded/reprogrammed from the recall, it causes the regular battery to die due to and system overload to the regular battery. The dealer wouldn’t take responsibility or Jeep wouldn’t take responsibility. The dealer wanted to charge me $500 so I had the local Auto Zone replace the regular battery with a new battery for $238.00. I sent in a copy of the slip from the dealership to show what they had recommended and submitted a copy of the credit card receipt to Jeep and they are refusing to cover the replacement. I would not have had to replace the regular battery if the 68c recall didn’t cause my regular battery to die due to the overload. From my understanding they should have been replaced at the same time to keep this from happening. I want to be reimbursed for replacing the battery, for the cost of the tow and for the diagnostic at Thomson Motor Center.

We took the car in for the death shake and were informed there was a recall on the Jeep (25V741000). The dealership performed the maintenance work. The 12V battery was also inspected and listed as good. Since the repair, the 12V battery has shorted multiple times and finally ceased running yesterday. It has been two weeks since the dealership recall repair. While the recall specifically impacted the HV battery, the 12V is interconnected and the liklihood of that battery being impacted is high. The safety impact is the car temporarily not being able to gain power after stopping at red lights and the battery draining when stopped or turned off. The check engine light appears every time.

Jeep wrangler has 46k miles, 2 years, but battery died while car was running. Would not start once car engine shut down. I was stuck in the middle of a busy intersection and was out ant risk of an collision. Upon running diagnostics, battery is fully drained and alternator is not starting. Online forms suggest it could be the alternative battery, charging the start/stop function, that died and drained the charge from the main battery. Prior to the incident, there was a low voltage warning which got worse over 2 days, until ultimately it died completely.

History since I leased this vehicle: 1. Charging cord froze to vehicle when parked at a charging station outside and would not detach until it thawed. 2. Car was recalled for a battery issue and was allegedly fixed. 3. Car later died. The battery was completely dead for no apparent reason. I had to have the vehicle towed to the dealer for the battery to be replaced. They were not able to explain why the battery died. 4. Just received another recall for a High Voltage Battery fire risk issue that they have no remedy for as of yet. We are advised not to charge the vehicle or park it near any structures or other vehicles! 5. While driving home from work, the Jeep suddenly stopped moving. The console where the shift gear is began to flash and I had to put my foot on the brake, put the car into park and then put it back into drive to get it to move again. When it went back into drive it lurched forward. Luckily no one was behind me at the time or they likely would have smashed into me or I could have caused an accident. According to online research it is another on-going problem, one article reads there are hundreds of complaints on the Jeep forums with no fix saying: When customers take their Jeeps in, the service advisors have trouble diagnosing the issue. And while Jeep has issued some recalls, the problems remain and the electric Jeeps continue to fail.
