Model Years Affected: 2003, 2004, 2005, 2006

Average Mileage: 88,180 mi (57,500 mi - 129,000 mi)

Verified

A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

    I have been told I need a new engine. So it sits in my driveway for now. It needed an oil change before I went on vaca came home and my sister used it. The next day it sounded so loud like putting a card in the spokes on a bike. I am trying to figure out if it really is the engine??

    Loud top end ticking noise when engine warms up. Diagnosed the problem, valve lifters. We are going to replace all eight of them, along with spark plugs.
