EVs do fail without warning but the anecdotal evidence says it is rare and as a % no worse
I had read and understood your post!
In this specific case, If a customer is advised of the poor condition of a traction battery by the seller, that information is classed as part of the description of the goods. The buyer is responsible for making the decision whether to buy or leave. If the buyer decides to buy, it would be accepted the buyer is fully aware of the battery condition, and made a conscious informed decision to buy the vehicle with the impaired battery.
Under these circumstances, the buyer could not reject the vehicle if it fails becasue of the impaired battery, specifically becasue the battery condition was fully declared before sale, and the buyer chose to risk the issue.
But as the growing body of historical evidence proves, the reliability of EV batteries are surprisingly high , and there ae many other parts of cars ( solo and shared with ICE and EV) which are far more likely to cause a total failure of a modern car.
I fully agree Prof
The devil is in the detail.
If the seller in the very unlikely situation says the battery is duff then imo any future failure is down to the purchaser. However say the seller says the battery is already 50% used and it fails before the next 50% time frame is up then that’s down to the seller.
In practice I can’t see any dealer personally guaranteeing the battery. What I suspect they will do is refer to the manufacturers battery warranty, most of which seem to be 8-10 years.
My friend has 5 y old Tesla which has not been a bed of roses. He lives in the Cotswolds but has to take the car to Tesla Bristol which is on the South side near Cribbs Causeway. A 130 mile round trip.
His air suspension has failed twice, once the pump, secondly a sensor thing that cost a mint. The suspension bushes have needed replacement and the auto card reader security system needed a lot of TLC. .They also,like to change his expensive tyres at 3-4 mm!
He’s now looking at Polestar, China or Kia EV. The warranties / guarantees are generous especially the Koreans
