Went for oil change & tire rotation. First told I needed to spend approx $500 in maintenance items. Next got told my battery needed to be replaced bc they had to jump start my car 2x. I started my car 6x after I left the dealership just to see if I had any issues. My car started up each time with no problem. They wanted to charge me $170 for a battery I can purchase for $94. Then they didn't reset the tire monitor system and told me i had to bring it back up to them to fix bc they use a special tool to reset the tire monitor. Wrong! I looked it up on YouTube and it's a simple set of instructions. No "special tool". This dealership is frustrating and full of b.s.
