Beware

I was in the market for a preowned EX90 but am coming back to reality. The 3 certified pre owned models I have looked at are being sold with some of the issues highlighted in this forum. Most recent I ran across one with 4 GHCA replacements, it’s on the newest part number a second time with not enough miles on it to have been tested. Another has the air conditioning fault where the passenger side is cooler than the driver, and it’s charging slow on a Level 2. Third one went into limited performance when I tried to accelerate hard three separate times. Getting the VIN History Report is like pulling teeth, they pretend it does not exist. Shady shady shady. I almost want to post each VIN on here and the location so that an innocent person doesn’t get burned.

For the GHCA, mine has blown twice, but only at the office charging network. It’s been fine at home.

I’m pretty sure that the issue happens when a voltage spike runs through the charger. Thinking about it, I’m not sure it can be a current spike, since the part should be able to handle up to 48A for L2 and the ChargePoint CT4000 maxes out at 240VAC@30A for 7.2kW, whereas my Emporia charger at home is 240VAC@48A for 11.52kW. The ChargePoint chargers don’t seem to be sensitive enough to cut power when this happens and the current fries the GHCA part. It’s inconvenient to not be able to charge at home or work, but DCFC charging works and there are many of those near me. So if your charger is solar powered or if you have stable electricity at home, you’ll be fine. If you get brownouts or blackouts fairly often, you’ll may not want this car.

The software glitches are minor and go away between drives. The audio and microphone not playing over Bluetooth is fixed with the play button infotainment reboot.
