I need to disagree with you. DU's and Batteries should be the absolute most reliable part of the car. Most already know, I'm getting DU #4 tomorrow. First one was the Clunk, that got loud enough to echo between houses on my street. Second one was milling noise that was loud enough that Neighbors could hear it IN their homes as I drove by, and #3, has intermittent power loss at random times. #3 is a Revision P drive unit, and has been the most dangerous. In a Median making left turn, press the accelerator to complete my turn in between streches of cars coming from opposite direction, Wham, no power, DNRP turns Red, that oh schnit moment when that Semi is approaching while speeding.... Then all of a sudden powers back and it lurches forward. This has happened a number of times. It is scary, especially with children in the car. Granted, safest car in the world, but I'd rather not test that.
It's gone beyond nagging issue, and has dipped into the realm of just being dangerous. With each new Drive unit, they have had shorter and shorter life span. In fact, in hindsight, I had thought these power-loss problems with #3 were potholes and other bumps in the road, as at first, it happened so quick, it felt more like a bump. But now looking back, and how each time the power loss gets worse.... It was happening almost immediately since #3 install.
I will have had 4 drive units in my car in less then a year as of tomorrow. This is ridiculous. Battery.... I had the battery failure at 34,000. It was the contactor. I had the 60kWh "A" Pack. They were at least able to remedy that issue, and I rarely see people with contactor failures any longer, however, the drive unit issue seems to be getting worse, and number of people having repeat failures is increasing in my observation, not decreasing.
