“Recall 272 was addressed on Dec 31, 2024. ICCU and fuse replaced; software updated. On 4/26/2025, 'Low voltage on the 12 volt battery, stop safely’ warned came on when I tried to start the car. The car was used several times earlier in the day and is used daily (i.e., does not sit idle). No other warnings were noticed prior to this failure.”

“ICCU failed while driving. Risk was that I suddenly had to pull over safely, as my car would no longer accelerate. This is a known issue, yet they haven’t fully addressed it over years. I had it taken in for recall fixes, and the part still failed 2 weeks later. There was no warning before it happened. But failure signs appeared after.”

“Was pulling out of drive way. Loud pop heard in the car. Immediately car flashed warning telling me electrical system had an issue and I needed to pull over and have the car towed to a dealer for service. Was told the part was related to the iccu and would take a couple days to arrive. Part is now on back order. 3 weeks later I am still waiting with little to no update on timeline for repair.”
