Consumer Description

We had the Internal Charge Control Unit replaced due to a warranty recall a couple years ago and it failed again on Dec. 23, 2025. The car has been at the dealer ever since, waiting for a replacement ICCU. The car refuses to charge and the dealer has diagnosed the issue as a faulty ICCU. There were no warnings or problem indicators prior to failure. This is our only vehicle, so while there was no safety issue, there is definitely a convenience issue. We had to obtain a loaner.
