I have an EX30 had it almost 6 months also. No actual mechanical issues or faults, but have heard of the odd issue you speak of where the car is totally unresponsive, often its due to 12v issues and having no key it’s a big issue. As you cannot enter the car.
There is an emergency port to give the 12v some charge under the left front bumper. Sometimes though it’s just the battery itself that is faulty from the off. Had a golf in 2017 and within a few months it just wouldn’t start after a supermarket visit and needed replacing. RAC only had a bigger more powerful one and never had an issue after.
So the question is are they putting in smaller batteries to lower costs and weight and in some situations, that creates an issue. After all the 12v is a critical part of any Ev still.
I wonder do you plug the car in to charge a lot like on IOG and for long periods of time, where the car is not actually charging for periods but still creating slots and waking the car. As if the car goes to sleep it might then not wake to charge, which is another issue many EV owners suffer with.
I don’t dynamic charge you see. I set it all in the car and it is something I have wondered about. I generally don’t let the soc get below 20% and charge to 90%
Alternately it could be a hardware or software issue that stops the car from sending charge from the traction battery to the 12v, or something is draining it.
The issue is they won’t exchange it for a different ex30.
You’d have to order again and the cost of AP on ex30 is now over 4k. As it has risen hugely since 6 months ago, when it was £1999. So IMO I would look at something else. I agree the ex30 is a great little package. Suits me down to the T also and I don’t know what else I’d select, as I need something around 4.2m long to fit onto my offroad parking space.
What exactly happens.
I have sat in mine watching videos with climate on for over an hour and car has used 1 or 2 kwh and not had one issue and I also do lots of very short journeys. That power is being provided to the 12v. So it is constantly draining and recharging, Seems to be a weak link on any car. Even more so maybe on an EV.
The 12V battery in the Volvo EX30 is crucial for powering various low-voltage systems and components, essentially everything except the electric propulsion system itself.
The other problem is dealerships and getting the car actually looked at.
Autoglass broke my adas, fitting a new windscreen and it took over a month, just to get the car in to be seen by volvo. Then a wait for the part etc, another month it was actually at Volvo. Just from a stone.
So that time frame is rather normal these days. Having to wait for it to actual be seen even if it towed there by RAC. It will only be looked at if a slot is cancelled or when the next one is available. Which adds to the stress each time.
All dealerships are not equal, after all they usually part of a group. So maybe try another if its fixed and happens again. See if there tech is better qualified. As your best solution I feel would be to have the problem solved and fixed. Sometimes electrical shorts are hard to locate fix and how long do they have to diagnose the actual issue before the next customer is booked in.
I also did an AI search and it suggested
Ensure the main high-voltage battery pack is charged regularly, as the 12V battery relies on it for power. Avoid letting the charge level drop below 20% to prevent the 12V battery from also going flat.
Preventing parasitic drains: Ensure all electrical components and accessories are switched off when the car is parked to avoid unnecessary drain on the 12V battery.
Hopefully you get it back and it gets sorted but if it doesn’t your options are pretty limited.
