XC90 Electrical Starting Issue

I had a similar problem with my XC90. Have you checked for any voltage drops or shorts in the wiring harness? The car's electrical system is like a complex network; a single faulty connection can cause all sorts of headaches. Does the problem only happen on cold starts, or is it intermittent?

Thanks for the quick response! Where exactly did you find the voltage drops in your XC90? Was it difficult to access? And was it a similar experience with starting issues?

Yes, the symptoms were the same, quite hard to start. Given the complexity of modern vehicle electrics, I would suggest a workshop diagnoses it. It could be something minor, like a faulty circuit breaker, but it could also be more involved. They have the tools to pinpoint the exact location of the fault, and it's often more cost-effective than chasing ghosts.

Thanks a lot! I took it to a workshop, and you were right, the battery was defective. They replaced it, and the car starts perfectly now. The final bill came to 290€. I really appreciate the help!
