Chrysler Pacifica Problem
32 Reports

Model Years Affected: 2004, 2005, 2006

Engines Affected: 3.5L V6, 3.8L V6

The engine may develop a ticking noise, often caused by a broken retaining pin on the rocker arm shaft. When the pin breaks, the shaft can spin blocking the oil passage the rocker arms (which causes the ticking noise). The rocker arm shafts, rocker arms, and pedestals (sold as a kit) are commonly replaced in order to correct this condition.

    My Pacifica engine just started clacking as if it were gonna blow! A repair center said the rocker arms are going bad and gave me an estimate of $1500 to fix. They said they'd just keep driving it as it is. People stare when I pull into a gas station. Its that loud! I'm so upset because I loved this car until now. The trade in value for it should be $6000 however a dealer said they'd only give me $2500 for it because of how it sounds. Now I'm stuck with it!

    tgicking started about a week before Christmas 2010. By the time the we got it to the dealer, it was knocking like a diesel and the fuel economy fell to around 11mpg. Dealer says rocker assy and it's gonna runs just shy of $600. Extended Warranty Co says all parts are covers but they are trying to say I failed to maintain the vehicle. We got it with 39K on it and since that time I've changed the oil EVERY 3000 mi just like the reminder tells me to. Dealership say that it is common in these engines and there is nothing I could have doen to cause this. If only I had known....I'd went with the 4.0L. Love the car though...just not the engine.

    I have had the ticking sound a couple of times with my Pacifica which was previously caused by low oil (this thing burns a quart every 3K miles) but this time it won't go away.

    ticking noise from front of the engine. Two diagnosis the dealer says removed front valve cover and rocker arm shaft, shaft shows some wear. oil has heavy metalic tint probed around cylinder head with magnet, found small pieces of metal that looked like bearing material. they charged me 240 dollars and told me I need to replace the engine to the tune of 7000.00 dollars. Second opinion said I need to replace the rocker arm pedastals. 2 hrs labor and 200 dollars in parts. I haven't done anything yet what would you do?

    Ticking sound coming from engine. Get's worse when drive uphill. The check engine light has never turned on. My mechanics says it needs lifter replacement at minimum. The repair starts at $2000 and could be much more.

    I also have the ticking noise. Checked the oil and it was 4 quarts low. It has been 4000 miles since the last oil change. The dealership is going to charge me $130 just to diagnose what the problem is..I have an extended warranty, but I'm sure they are going to give me a hard time about the oil changes as well.. I do change the oil every 4500 miles, but no documentation to prove it. I'm crossing my fingers, hoping they will cover the parts.

    Brake light will not go off and motor ticking. The last oil change we put heavy duty oil in try to stop ticking but it still ticks.

    The engine often makes a ticking sound. It is also often accompanied by a "purring" sound.

    Ticking noise like a bad valve, plus just started a clunking noise, but only sometimes when slowing or accelerating. Have extended warranty, but told that due to negligence (have maintained my vehicle), that this problem is mine alone. I have been also told that this issue is very very uncommon, although I can see now that it is just swept under so Chrysler does not have to pay for repairs.
