First time with a Hybrid Car. Check Engine Light and What to Do Next?

Hello everyone, I’ve been driving a used 2022 Toyota Corolla Hybrid for about 1.5 years now (24k miles). When I bought it, I asked about costs and warranty, and everyone was super helpful here.

Now, I’m back because the check engine light came on for the first time. The car wasn’t starting after sitting for a few days in the cold (below freezing at times). I jump-started it after watching a few videos, but then the check engine light appeared with a message to go to the dealership. I nervously drove the car this morning.

After calling the dealership, they said the diagnostic alone would cost $200, not including repairs or anything. I didn’t expect the diagnosis to be this expensive.

So I’ve got a few questions:

  1. What should be my next steps? Should I try a local mechanic instead of the dealer? The car is still pretty new and the cold weather might be the cause, but it’s my first hybrid, so I’m looking for honest advice.

  2. Is it normal for hybrids to have issues in the winter? I’ve heard a little about it but didn’t expect this kind of problem.

  3. How can I prevent this from happening again? Should I start the car more often?

Looking forward to your advice. Thanks!

If the issue might be covered under warranty, then take the car to the dealer. If it’s something under warranty, they should waive the diagnostic fee. But if you’re unsure, you might want to visit a trusted local mechanic for a cheaper diagnostic. If it turns out to be something simple and not covered, you’ll save money on the diagnostic. If it is covered, you might pay a bit more, but not by much. I think it’s great you’re asking for advice first! I’m new to hybrids myself, so I’m curious about others’ experiences too.

I’m a new Corolla hybrid owner too. The 12v battery that powers the car’s electronics gets charged by the hybrid battery when the car is running (there’s a voltage converter instead of a regular alternator). If you’re not driving long distances often, the 12v battery might not charge fully. I keep my 12v battery topped up by using a trickle charger every other weekend. I also have a portable booster in my trunk just in case. The problems didn’t start until the cold weather hit. It seems like it’s just a thing with hybrids in winter.
