My cars coolant is leaking and the source is unknown. My car has overheated twice and my mechanic has been unable to find what needs to be repaired. The coolant has need to to be filled twice within a 6 month period. Now my car is having other issues with the catalyst system that lead me to believe the coolant leak might be affecting these other parts. My catalytic converter was already replaced and the same code has popped up 4 months later.

Once again, my doors unlocked then relocked, my dashboard lights went out and the engine stalled. I was on the KU campus when this happened 3 times within 6 blocks. This is getting very scary, especially when i am in a busy area of town. No codes have ever popped up. This has been happening since May 2022. I will keep reporting, hopefully there will be a recall soon. Very frustrated with this situation!
