I own a 2012 TL with Technology Package. It now has 97,700 miles, I am the only owner, it has been excellently maintained and I intend to try to keep it for another year or two. To do so, I am told that I must/should do a 100,000 mile service which I understand may cost as much as $1,800.00! I'm not clear on all that is included for this hefty cost, but I have heard specifically that 1. timing belt will be changed, 2. 6 platinum-tip spark plugs, 3. water pump and, if necessary 4. serpentine belt.
My question, especially for those who have recently had this service performed, is: what else should/must be included with this major service? $1,800.00 is a lot of mula! So, any help will be appreciated!!!
