2018 Chrysler Pacifica: sudden loss of power

Filed Oct 20, 2026 · Electrical, Fuel system · CA

My van has been reliable for 5 years until recall 73B was performed. Ever since it's install I have had 7 repair attempts and 250+ days out of service. Each repair attempt is preceesed by check engine lights, service hybrid system, check electronic throttle control, red wrench, blind spot temporarily unavailable, (occasionally) service airbag, service shifter, and stability control lights. Chrysler has been unable to fix this issue. They have replaced the abs module, 12v battery, can bus's, wiring, battery coolant heater, eflite motors and reducers, 400v battery, and the under hood wiring harness. Engineering has been involved, star cases opened, and technicians flown in to address these issues. The DTC code scans reveal many communication codes, both active and permanent. The last scan had 23 active codes. No one can tell me if this van is safe to drive, I don't think it is. I have had no drive events, and lost power steering momentarily at highway speeds. The latest incident had the messages start appearing at 45 mph. This can is unfit to be on the road, and stellantis does not seem to be able to fix it

Intermittent loss of power steering, giving the sensation of "sticking" when the wheel is turned about 30 degrees clockwise. Generally happens at highway speeds, but can happen at lower speeds too. Steering feels locked me momentarily, needing extra force to either continue the turn past 30 degrees or to bring it back to center.

The wheel suddenly became difficult to turn while driving due to a loss of power steering, but it soon regained normal function. However, not many trips after that, the power steering completely failed. It has not regained function.

Another incidence of a 2018 Chrysler Pacifica with "sticky" or intermittent loss of power steering while driving. This is not chronic at this point in time but is a problem that can catch one out if not paying attention. I ran my vin # and it shows no outstanding unfixed recalls but obviously this is a recurring safety problem that needs to be addressed. Recall V53 / the federal safety agency 19V‑348 are the numbers that pop up from NUMEROUS complaints describing this very same issue.

Lots of power going up steep hills. Especially while AC is on. Almost complete loss of power yesterday with vehicle behind me.

I bought my 2018 Chrysler Pacifica Touring van in February 2018 brand new from Burlington Chrysler, Burlington, NJ. In May 2026 the check engine light came on and I brought the van to my mechanic. The code he pulled was for #5 cylinder. I had the repair done. A month later in June of 2026 the che ck engine light came back on and this time the code was for the catalytic converter. On July 21, 2026 I brought the van back to my mechanic for an oil change and replacement of catalytic converter. When they put the van up, it was discovered that coolant had leaked all through the exhaust system and my mechanic suspected there was a crack in the head gasket. He searched through the Pacifica Forum online and found many, many complaints about this same issue. My mechanic completed the oil change and filled the car with coolant because it had none and advised me to bring the car to the dealership which I did. On July 22, 2026 Chrysler called and advised I need an entirely new motor. I now have to pay out-of-pocket $14,098 + tax for a new motor and catalytic converter. Chrysler advised there is nothing else they could do for me because the car is out of warranty. However, the car is only 8 years old with 76,000 miles and has had all the regular maintenance and oil changes required. It should not need to have the motor replaced at this point unless there's a major defect with these engines. I feel this is a MAJOR safety issue as this head gasket crack occurred without any warning other than the codes for #5 cylinder and catalytic converter failures. Without coolant, the car would have overheated at some point and caused engine failure and power loss. As I drive mainly on highways, this defect had the potential to cause a very bad accident. Due to the overwhelming number of complaints about this issue, I feel this warrants an investigation by your organization.

I own a 2018 Chrysler Pacifica equipped with the 3.6L Pentastar V6 engine. At approximately 81,600 miles, the vehicle developed a check engine light and a Cylinder 5 misfire (P0305). The vehicle began exhibiting hard starts, rough engine operation during cold starts, white smoke from the exhaust, and coolant loss with no obvious external leak. An independent repair facility initially diagnosed the vehicle and found evidence suggesting coolant intrusion into Cylinder 5. The vehicle was then inspected by a Chrysler dealership. The dealership confirmed that coolant was present inside Cylinder 5 using a borescope inspection. The dealership recommended replacement of the cylinder head gasket. The safety concern is that the failure developed with little warning other than a check engine light and intermittent rough operation. The engine misfires on startup and can run rough, which could result in reduced power, hesitation, stalling, or loss of acceleration while operating the vehicle. The vehicle also consumes coolant internally, which may lead to engine overheating or further engine damage if not detected quickly. During my research, I found numerous reports from other owners describing similar coolant intrusion, head gasket failures, and Cylinder 5 misfires in Chrysler vehicles equipped with the 3.6L Pentastar engine. Despite the apparent frequency of these complaints, I am not aware of any recall addressing this issue. In my case, the repair estimate is approximately $5,000 for head gasket replacement. I am submitting this report because coolant intrusion into a combustion cylinder can create a significant safety concern due to engine misfires, loss of performance, and the potential for engine failure while driving. I believe this issue warrants investigation to determine whether a defect exists affecting other vehicles with this engine.

I own a 2018 Chrysler Pacifica with approximately 79,000 miles. The check engine light illuminated, so I had the vehicle scanned at an auto parts store. The diagnostic code indicated a cylinder 3 misfire. After leaving the store, the vehicle quickly began displaying overheating warnings. The overheating occurred suddenly, and the vehicle had been driven very little after the check engine light first came on. Because of the overheating, I had the vehicle towed to a repair shop. The shop initially repaired the vehicle and tested for misfires but reported that they found no remaining issues. However, immediately after leaving the shop, the check engine light returned with the same cylinder 3 misfire code. The vehicle was returned to the repair shop for further diagnosis. After additional inspection, the shop determined that the engine had a blown head gasket. This resulted in major engine damage and the possibility of a complete engine replacement despite the vehicle having only 79,000 miles. I am submitting this complaint because the engine failure occurred unexpectedly and without warning other than the check engine light. The rapid progression from a misfire to severe overheating created a potential safety hazard due to the risk of sudden engine failure or loss of power while driving. I believe this premature engine failure may indicate a defect affecting other 2018 Chrysler Pacifica vehicles.

The van has just approx 55000 miles. While driving on highway, it suddenly lost power and from 60mph it came down to 20 miles in a matter of few seconds after few violent jerks. I was lucky that no vehicle was behind me. After that I pulled a side and then again started. It kept jerking and loosing power. Very carefully I got it to a mechanic. They are checking but they say looks like transmission issues. Engine light also came on. This happened few months ago however it was not this bad and my mechanic looked and he could not find anything. That problem went away after that incident. Kindly advise what to do in this situation. Chrysler Pacifica 2018 This van has lots of problems in other crucial area also like air fender switch, oil hose and cover that went bad as they are made of plastic. Then the trans mounts broke. It costed me dearly. Please Advice what to do? Best regards [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle experienced intermittent and sudden loss of power steering assist while driving. Steering becomes extremely heavy without warning, creating a risk of loss of control. This is the same symptom addressed by Recall V53 (Power Steering Assist Loss). The recall was previously marked as completed, but the defect has returned, indicating an ineffective recall remedy. Issue occurs during normal driving and is reproducible. Chrysler claims safety recalls have a warranty and will not repair or reinspect it.
