Which Chrysler Pacifica years have the most engine problems?

The 2018 model year has the most by far, with 187 of 318 engine complaints, mainly head gasket failure. The 2019 through 2023 years have fewer, and 2024 and 2025 have very few. Those newest years are too new to call better, since complaints build up over time.

Is it safe to drive a Pacifica with a bad head gasket?

Owners say no. Coolant loss can cause overheating, misfires, and sudden power loss on the highway. Some described coasting across lanes of traffic. Having it checked quickly matters, since continued driving can destroy the engine and turn a gasket job into a full replacement.

Is there a recall for Pacifica engine problems?

Federal recall records show no recalls in this engine problem area. Owners complain that Chrysler offered little help with out-of-warranty head gasket failures. Check the vehicle's VIN with the manufacturer or NHTSA for any open recalls in other areas before you buy.

How much does a Pacifica engine repair cost?

Owners report a wide range. One repair cost $3,500. Dealers quoted $6,000 for one head and $9,500 for both. A shop estimated $9,000 for an engine, and another dealer quoted around $16,000. A $900 misfire repair failed within two days for one owner.

Why does my Pacifica stall with a Stop Safely message?

Owners on 2021 through 2024 vans report this warning followed by power loss, often on the highway. Dealers frequently find no stored fault, and some shutdowns continued after a software update. The data does not name a confirmed cause, so ask a dealer to document each event.

Chrysler Pacifica Engine Problems

Head gasket failure on the Chrysler Pacifica's 3.6L V6 lets coolant leak into the cylinders, mostly in 2018 vans, and can end in a new engine.

Pacifica engine complaints by model year

The 2018 model year dominates, with 187 of the 318 engine complaints and the highest rate per vehicle sold. The 2019 through 2023 vans each have between 16 and 35 complaints, mostly head gasket trouble in the early years and stalling in the later ones. The 2024 and 2025 vans have only a handful, and 2026 has none. Those years are too new to judge. They have simply had less time on the road to collect complaints, so a low count does not make them safer bets.

Owner complaints filed with NHTSA under engine, engine and engine cooling. Newer model years have had less time to collect complaints.

What goes wrong

The main engine problem is a failed head gasket on the 3.6L V6. Coolant leaks into a cylinder, often with no puddle under the van. Owners see a check engine light, a misfire code, rough idle, shaking, and a coolant reservoir that keeps running low. Some vans overheat. Many shops end up recommending a new head or a full engine.

Newer vans show a different engine complaint: stalling at highway speed after a warning that the van will shut off soon. Owners report no crashes and no injuries in this area, and federal recall records list no engine recalls. Fire is the exception. Six 2018 complaints involve fire, and some of those point to overheated catalytic converters. Sudden power loss on a highway is the real safety risk, and a failed engine leaves the van undrivable.

Symptoms owners report

Coolant loss with no leak

Owners keep topping off the reservoir and find no drip on the ground. Some see a pressurized reservoir on a cold engine. Coolant is leaking into a cylinder, and the van can overheat on the freeway without warning.

Misfire and check engine light

A misfire code, most often for cylinder 3, 4, 5 or 6, comes with rough idle, shaking, a ticking noise, or a chug on startup. Replacing the coil and spark plug often does not fix it, and the light returns.

Stall after a shut-off warning

The van shows a message that it will shut off soon, then loses power, often at freeway speed or in traffic. It may restart after a few minutes. Dealers often find no stored fault, and repeat failures are common.

Internal engine damage

Some vans fail inside: a seized lifter bearing, metal shavings in the oil, or worn rocker arms and lifters. In 2025 complaints, a check engine light came before the dealer replaced the engine, and one van is on its third.

Overheated catalytic converters

Owners describe a burning smell and sudden power loss, and some report cracked or heat-damaged converters. A technician called one case a known catalytic converter issue. These reports include the 2018 fire complaints.

Oil leaks and start/stop trouble

A burning oil smell traced to leaking seals on the oil filter housing and valve covers shows up in several years. Some vans also fail to restart at traffic lights when the auto start/stop system shuts the engine off.

When the problems start

On 2018 vans, head gasket failures cluster from about 55,000 to 74,121 miles, with more between 104,000 and 120,000. One owner reports a diagnosis at about 51,000 miles. On 2019 vans, most reports fall between about 55,000 and 93,000 miles, and 2020 failures cluster around 58,000. Stalling and internal failures on newer vans can come much sooner, from under 150 miles to around 28,000 miles.

Repairs and recalls

Federal recall records list no recalls in this area, so owners pay for repairs themselves once the warranty ends. Several say the failure came just after the powertrain warranty expired. Fixes range from a new head gasket or cylinder head to a full engine. Owners quote $3,500 and $6,000 for one-side repairs, $9,500 to do both heads, $9,000 for an engine, and one dealer estimate of $16,000. A dealer software update did not stop the shutdowns on some 2022 vans.

Checking a used Pacifica for engine problems

Ask for service records showing coolant top-offs, and check the reservoir level on a cold engine before the test drive.
Scan for stored misfire codes and pending check engine codes, and ask if any coil or spark plug swaps were done.
Have a shop run a cooling system block test, which can show combustion gases in the coolant before a gasket fully fails.
Idle the van for several minutes and watch for shaking, rough running, a ticking noise, or any rising temperature.
Ask whether the van has ever shown a stop-safely or shut-off warning, and test the start/stop system at lights.
Look for oil seepage around the oil filter housing and valve covers, and smell for burning near the exhaust.

A VIN check shows whether the car you're looking at had its recall work done, plus accident and title history.
