Another software-related recall — are cars getting too centralized?

Write down what you already tried. A second data point from another 2017 Nissan Altima owner helps more than a generic diagnosis. I'd do that before spending real money. Post the numbers (or the code) and people can get more specific. I'd sleep better after that step, even if it finds nothing. This is the version I'd tell a friend.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Nissan Altima, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Post the numbers (or the code) and people can get more specific. If the story changes I'll post the new data.

Thanks — that narrowed it. I'm going to try the simpler check on the 2017 Nissan Altima first. That's my plan before I call anyone.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Nissan Altima, a specialist hour can be cheaper than another round of parts. That's where I'd start. Post the numbers (or the code) and people can get more specific. Make the next action something you can finish this week. I'm keeping receipts and dates in one folder.
