Hi All,
Picking up this thread as it was the only semi-relevant one to an issue I had today.
2016 XC90 with 33k miles. Very few issues, with an odd code (reduced engine performance) thrown a couple of times previously over the vehicle life.
I was reversing out of a parking spot and when shifting from reverse to drive the engine cut out. Like described in the thread above, engine cranked well for a few seconds, gauge cluster etc is fine. Just no engine start. I tried cranking the engine several times, with no luck.
I couldn't see any problems in the engine bay and was expecting to need a tow, but after 5 to 10 mins of letting the vehicle sit, tried cranking the engine again. This time it started, with the "reduced engine performance" warning showing briefly in the information line of the gauge cluster. I drove home with no further drama.
Temporary fuel delivery problem? Software glitch? If there are further issues I'll post again, but hopefully it was a transient problem.
