Yes, dealers are ever ready to do stuff that isn't necessary. They even suggest rotating/balancing tyres every 5,000 km. I get it done about 15,000 km (usually do it myself) and a quick drive usually confirms that balancing isn't necessary. If a tyre is out of balance, my local guy does it for $10.Indeed. When I had my Sorento in for a warranty repair they tried to sell me all kinds of crap (tire rotation, oil change, air/cabin filters, nitrogen in the tires, blah blah). They even said they "were required" to balance the tires if I had them rotated (for $80).
Had a bit of a bump on a kerb not loing ago and took the car in for a 4-wheel laser alignment. Cost $99 and they did a rotation and balance; not a bad price.
