Is the Audi e-tron / Q8 e-tron reliable?

We have found no documented faults with the electric motor or the power electronics; what is on record are two precautionary high-voltage battery recalls: moisture at the connection (first 2019 units) and cell modules with a risk of overheating (built 2018-2022). Check the chassis number and the battery's state of health.[1][2][3]

Is the Dacia Spring reliable?

The Spring's drivetrain is simple, but Fiches-auto.fr records the charger and charging port as the category with the most testimonies (17 out of 73), and about nine serious alerts for the traction battery; the motor barely features. The sample is made up of voluntary reviews.[4]
