I have a 2006 Toyota Highlander Hybrid with about 130,000. miles. The dealership is telling me that I should replace the spark plugs. The cost will be over $600.00. Does this sound about right?
No way. repairpal.com estimate is $175 to $230 for new spark plugs. Are you sure the dealership estimate was only for new plugs? If so, someone has a boat payment to make…
At that mileage the plugs definitely need replacing. The dealer price seems very high, unless they replace the wires and a number of other things as well.
I would get a second estimate from an independent shop.
It’s an 8 year old 'Yota. Spark plugs are a common maintenance item any shop can handle. I’d get a second opinion from an independent shop, but insist on Denso plugs. They are the OEM supplier, and work best in your truck.
Denso or NGK are both OEM suppliers to Toyota. Either is fine.
$600 is outrageous. It may have to be put on a lift to get to the back plugs, but it shouldn’t cost anywhere near $600 - even if they use iridium plugs.
Is it possible that the dealer is recommending the 120,000 mile service–including spark plug maintenance AND some other items?
We don’t have your owner’s manual handy. Please tell us when it says the plugs should be replaced.
I found this - here. It doesn’t look like it would cost $600.00. Note: Unless I missed it, it’s the first mention of changing spark plugs…
