This type of problem can have any number of causes. The best option is to have the car scanned electronically to see what fault codes have been logged by the on-board computer.

You could be looking at a fuel issue, something purely mechanical (like the idle-speed set too low) a blocked air-filter, a computer issue or any number of sensors that are not playing ball. But until you interpret the fault codes, you’ll be flying blind and potentially replacing things that aren’t the cause of the stalling problem.

I’d certainly be taking the vehicle back to the workshop that serviced it and pointing out that the problem only occurred after they'd 'fixed' it.

There’s nothing to suggest the Outlander is a lemon. Just read up on all the reviews of the 2019 model. That should be enough to convince you it’s a decent SUV. The Black Edition is a variant of the Outlander with a long list of special features. I don’t see any reason to wait for the 2020 model.

There’s not much between them, but the Honda is regarded as being a little better than the Nissan overall. It’s well-equipped, good value, and practical. Another to consider is the Mazda CX-5.
