Seeking Advice on Troubleshooting 2013 Volvo XC90 Start-Stop System and Other Issues

Hey folks, I'm having some trouble with my 2013 Volvo XC90 Gasoline engine. It's not starting up, fuel efficiency is down, a warning light pops up on the speedo, and the lights are dimming or flickering at times. I'm suspecting something's off with the engine start-stop system, but I need your help to narrow down the problem. Has anyone had a similar experience? How did you resolve it at the workshop? Would appreciate your tips and advice. Thanks in advance!

Hey there, some experience here! I had a similar problem with my 2011 Volvo XC60 a while back. It turned out to be a weak old battery, not really the start-stop system. Took it to my local mech and had to fork out about 290 Euro for a new one and installation. Bummer, right? But it fixed all the symptoms you're describing. Just to be sure though, could you let me know about any recent changes in your driving routine or check if there's any corrosion on the battery terminals? Happy to help out more with a bit more info. Cheers!

Hey, thanks for the advice! As for my driving routine, nothing's changed much recently. And I just checked the battery terminals, they're all clean and good. My latest service was at 100357 KM, but these issues have only started popping up in the last few weeks. I'll take your advice and get the battery checked at the garage next. Fingers crossed! Cheers!

You're welcome! Good to hear that there's no corrosion on the battery terminals. Given your car mileage and the recent emergence of these symptoms, it does increasingly sound like a dwindling battery. My issues started shortly after 100k kilometres as well. I seriously suggest getting your battery tested ASAP. There's a chance it's not holding a charge as efficiently. It's vital since it affects the overall electrical system of the vehicle which indeed is responsible for starting the engine, lights, and the speedo-meters. There's also no harm in checking the alternator as well. A faulty alternator could result in poor fuel economy and problems with lights too. But yes, start with the battery test. Wishing you good luck for diagnostics at the garage and hope your Volvo gets back on track soon! Cheers!

Thanks a ton! Your advice is really helpful. I'll get my battery and alternator checked at a reliable garage tomorrow first thing in the morning. 100k kilometres does seem about the right time for battery trouble, I suppose. Here's hoping that solves the problems with my XC90. I'll keep you updated. Cheers for now!
