Hi,

I hope you can help me with a perplexing issue I've encountered with my car. Here's what happened:

My wife took our dog for a walk, and the car was driving fine when she traveled to the park. However, upon returning and trying to start the car, the engine light suddenly appeared, and the car could only move at a sluggish 5mph. We managed to get back home safely.

The next day, when I attempted to reverse the car into our driveway, it suddenly died after just 10 seconds, as if the battery had drained completely.

My mechanic had a look and tried to diagnose the problem. He suspected it might be the throttle, so he changed it, but unfortunately, nothing changed. He's now at a loss as to what the issue might be.

As someone with very limited knowledge about cars, I'm turning to you for advice and guidance. Could you please suggest what might be wrong or any further steps we can take to resolve this problem?

Your assistance would be greatly appreciated.

Thank you.

btw, car had only 50k miles
