A few months ago I got a warning to book my car in for a service as there was an issue with the HV battery. No problem, booked in, replacement battery fitted, hire car provided - no issues.
However, they charged the replacement to 97% and it only showed 280 miles of range! I complained and they said it need to calibrate. I was told charge to 100% and leave it for 2 hours. Run it to below 10% leave it for 2 hours. Repeat 10 times and it would sort the BMS and be as expected. The car wouldn’t charge to 100% for a good 5 iterations of this!
Anyway, after every iteration, the range dropped and dropped until it got to 236 miles at 99%. I complained again and they told me to do the above procedure again as there was a battery imbalance. I humoured them and did it but they closed the service request!
Obviously no change so opened another ticket. They said everything was fine and do the above procedure again, they then tried to close the ticket but left it open for any final questions.
I politely told them to poke it. If they didn’t replace the battery I would be returning the car to a very awkward location and leave it until it was resolved. They very quickly discovered the battery was sub-standard and offered a new one! Absolute jokers! But all good that another is inbound!
Let’s see what happens this time….
