I also vote to keep the car if you want to save money.
Let's say you'll have to pay for all the broken parts:
20,000 for the main battery
4,500 for the Cabin Heater
4,000 for the A/C
4,000 for the steering wheel issue
3,000 for the MCU
3,342 for the 12V issue (DC-to-DC converter)
2,350 for the onboard charger
That's $41,192.00
Your equity is: 24K, which means you still need to pay $41,192-$24,000=$17,192 more after all those repairs above.
On the other hand, your new car costs $55,450, minus your $24 equity , which means you still need to pay $55,450-$24,000=$31,450 more.
Remember your older DMV and Insurance fees are lower than your new car
And after 4 years, you might have to deal with a broken heat pump and other things for your brand new car too!
