Vehicle failed to start and a jump is required to start the vehicle for the first time on 10/6/2026. This has now happened numerous times and at times when the vehicle's power train batteries are charged. An small portable charging device has been purchased to jump the vehicle which eliminates the need to call for roadside assistance. Roadside assistance has take over 2 hour to response. An error on the dash indicated the 12 Volt battery has lost charge. There is a red circle message displayed on the dash. The vehicle was taken to Batteries Plus and a battery and alternator test. No problems were noted. The vehicle is scheduled for a dealer inspection on 10/22/2026.

The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.

I charged my car at a level 3 fast charger on a road trip. After completing my charge, the AC stopped working. The fan worked but it was only blowing hot air. Normally this would be a nuisance, but the day was about 114 degrees and the car’s interior was probably close to 140 degrees.

I took it to the dealer who initially thought it need the coolant to be recharged. It turns out that the inverter for the A/C died. Apparently this has some connection to the known issues with the ICCU, which in my case ju
