Got our Tucson at the end of May 2021. The BlueLink reports started kicking in maybe in July, (around 6 weeks after purchase, as I recall) and were initially accurate. That stopped some time in October, not sure exactly when, but there has been a growing discrepancy between the actual odometer reading and the BlueLink reading. The numbers are increasing, but there doesn't appear to be any linear relationship between actual mileage and BlueLink mielage. On December 3rd, I had to take my car in for a service (windshield washer motor/pump failed and had to be replaced, and the recorded mileage was 5070 miles, whereas 8 hours later, BlueLink was telling me I'd done 8300 miles (which would equate to having travelled at around 400 mph and would've also resulted in phenomenal gas mileage). This isn't a simple miles to km "conversion" thing. The annoying thing is that it appears the BlueLink mileage triggers me to get numerous emails telling me to get my vehicle serviced urgently. I've attempted to contact Hyundai several times and was told BlueLink would be contacting me within a few business days, but they've failed to live up to that on each occasion. At this point, BlueLink seems pretty worthless, which given it was thrown in free for a period of time, I suppose it technically is, but they are not doing a good job at persuading folks to subscribe at whatever the fee will be once the trial is over.
