The Most Common Chrysler Pacifica Problems You Should Know About

A new car should last you a good while, getting you from point A to point B reliably and safely. Before you committed, you probably did your research to make sure it would do just that. But every car seems to have issues at least at some point, including the Chrysler PacificaRepairPal.com breaks it down and looks across model years to track matters reported by consumers. While fewer than many other cars that had reported issues, there are still 12 overall problems reported regarding the Chrysler Pacifica. Here are the top three complaints.

The Chrysler Pacifica suffers from a ticking noise from the engine

Over 205 reports made the engine’s ticking noise the top complaint among Chrysler Pacifica drivers. The years affected were 2004-2008, and the ticking occurred as early as 15,000 miles, with the average being 104,500 miles. The 3.5-liter, 3.8-liter, and 4.0-liter V6 engines were among the affected.

The issue was thought to be caused by a broken retaining pin on the rocker arm shaft, which caused the pin to block the oil passage in the rocker arms and created the ticking sound. Most often, a kit that includes rocker arm shafts, rocker arms, and pedestals was used to replace the old parts and correct the issue. On average, consumers reported it would cost between $80 to $1,500 to fix, depending on if they did it themselves or had a professional fix it and whether they used the kit or only did one part.

Carbon buildup in valves

Affecting the Chrysler Pacifica’s 3.5-liter and 4.0-liter V6 engines from 2004-2008 was carbon buildup in valves. This made the check engine light come on and indicated that multiple cylinders were misfiring. To solve this, the combustion chamber needs to be cleaned out to remove all the carbon and potentially have the valve spring retainers updated to prevent it from happening again.

62 reports in total came in about this issue, which generally affected the Pacifica on average at 131,000 miles, but could happen at as low as 60,000 miles. Consumers reported that the buildup would cause their car to stutter when trying to maintain a steady speed. They stated that mechanics would fix it, but it would quickly go back to the same problem again and that there was no estimate for the cost to repair. 

Static discharge causes problems

Coming in as the third most common issue with the Chrysler Pacifica was that static discharge or loose wire connections could cause problems. This generally meant that the power seat memory, seat heaters, and adjustable pedals would have issues. This was resolved with revised seat modules that resist the effects of static discharge.

There were 48 reports for the 2004-2008 models, with the average mileage the problem occurred at being 106,000 miles. The issue could arise as early as 52,000 miles, and consumers complained it would be intermittent and random. One estimate is that it would cost $350 to fix. Further down the list, static discharge issues came up again but in the door handles, causing a loss of function.

Numerous other issues were reported for the Chrysler Pacifica, including water leaks from the HVAC case not sealing at the bulkhead, misalignment of the drive belt pulleys causing noise, and software updates being needed for the powertrain control module. The year with the most problems overall was the 2004 Chrysler Pacifica, coming in at 11 issues.

But since 2008, the Pacifica has actually been a mostly problem-free car, with the exception of two problems in 2017. This is a good sign, and that shows Chrysler is making an effort to fix the issues of the past and is getting better every year
