2018 CHRYSLER PACIFICA Complaints

The contact owns a 2018 Chrysler Pacifica. While driving at an undisclosed speed on the highway, the vehicle suddenly veered to the left on its own. The contact continued driving for a short distance before the vehicle pulled hard to the left a second time. The contact pulled over safely and contacted law enforcement, and the vehicle was subsequently escorted off the highway. The contact then observed multiple warning indicators illuminated on the instrument cluster panel, including the power steering warning light, but could not recall the remaining indicators. The contact referenced NHTSA Campaign Number: 19V348000 (Electrical System) to be the cause of the incident however, the VIN was not included in the recall. The vehicle was towed to a independent where it was diagnosed to have a loss of communication Mod A. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 166,303.

2018 Chrysler Pacifica exhibits severe 'sticky' and binding steering at highway speeds (70+ mph). When maintaining a straight line or slight left curve, the steering wheel notches and resists physical effort when trying to turn back to the right. Correcting the vehicle requires sudden, excessive force to break the electronic resistance, causing a jerky movement that risks overcorrection and loss of vehicle control. This is a severe, intermittent tracking and safety hazard under the ongoing NHTSA EPS gear investigation.

What component or system failed or malfunctioned, and is it available for inspection upon request? The alternator snap off while driving on the highway. The snap was clean all bolts are still in the engine block. While driving all kinds of dashboard lights and overheating indicators turned on. How was your safety or the safety of others put at risk? This happens with warning or actions prior to the alternator falling out of the while driving. This put me at-risk of crash and endangering anyone on board, leaving me and family stranded on yhe highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Similar post online with same issues found. Dealer want 80% of the car value to repair and wont help. They recommend changing a cylinder head. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Chryslerbdealer ship inspected. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No signs or symptoms. After the alternator drop off, many issues arise. None prior.

Odometer 66466. Hybrid battery charge level 100%. When starting the vehicle the issue started with the transmission shifter knob stuck in gear Park. After turning off and on a few times, the transmission shifter knob would shift into Reverse. I then drove it to a dealer service for repair. During the drive several dash warning messages appeared. Also, the blind spot warning system did not function and the backup camera did not function. Dash warning messages while driving to dealer service: Parking Brake, TPS, Service Electronic Stability Control, engine, Red wrench, amber throttle, Brake, Service Electronic Throttle Control, Service Hybrid Electric Vehicle System. stability control, Blind Spot Alert, Arrived at dealer, kept engine on, brought service tech rep to vehicle and demonstrated the issue while in service bay. Mileage 66474. Last message I saw, Service Hybrid Electric Vehicle System. Friday, April 10 2026. The vehicle was in the shop for Service Hybrid Electric Vehicle System just 750 miles previous to this system failure. Dealer is unable to fix problem. Hybrid System still under warranty. Hybrid battery replaced last year, 12 volt battery replaced twice after. Vehicle is beyond unreliable, there is significant risk of failure at any time.

The contact owns a 2018 Chrysler Pacifica. The contact stated when attempting to charge the battery, the charger failed to work as intended . A dealer was contacted. The vehicle was towed to the dealer where it was diagnosed that the battery needed to be replaced and and they sent a request to the manfactuer in regards to replacing another battery. The vehicle was repaired as the battery was replaced three times. The manufacturer was notified of the failure and they could not give her an update and they informed her this is up to the dealer. The approximate mileage was 101,000.  

Positions during small steering corrections, especially at highway speeds and during straight-line driving. Condition feels like temporary increased steering effort or intermittent reduction of electric power steering assist. Additional force is required to move the steering wheel past the sticking point 11 o'clock or 1 o'clock. Once resistance releases, steering may suddenly move farther than intended, causing brief overcorrection or oversteer. Issue occurs repeatedly during lane correction maneuvers and creates a safety concern because steering input is not smooth, consistent, or predictable. Problem appears to be worsening over time. No warning lights were present when symptom occurred. Vehicle mileage at onset: 80,000. Current mileage: 82,500. This complaint appears related to NHTSA investigation PE25009 involving sticky steering and increased steering effort in 2017–2018 Chrysler Pacifica vehicles.

The manufacturer's mandatory 73B Safety Recall update (Vehicle Fires) creates a critical software-induced communication failure on the central vehicle network. Following the 73B flash, the vehicle developed an Active SGW U0001-00 CAN C Bus network fault, which permanently blocks data transmission and triggers an HCP U0412 hybrid battery fault. This network crash disables the hybrid propulsion systems, creating an unpredictable and hazardous driving condition. The manufacturer (Stellantis) and its authorized dealer (Seattle Jeep) are refusing to remedy this safety recall side effect under the vehicle's Hybrid Powertrain Warranty, instead forcing consumers to pay out-of-pocket diagnostic fees ($284.67) and multi-module software update fees ($812.50) to correct a defect injected by the recall software itself. This directly compromises vehicle safety and violates federal recall remedy mandates.

I was in a motor vehicle accident when my passenger side vehicle got t-boned on 3/22/26. My 2018 chrysler pacifica limited airbags failed to deploy and the driver and passenger sustained whiplash injuries.

In reference to recall query RQ24004, the appropriate software was installed under recall O3A for Loss of Motive Power on my 2018 Chrysler Pacifica Hybrid. However, on multiple occasions the vehicle has displayed "Stop Safely - Vehicle Will Shut Off Soon". Once on 6Apr2026 and again on 13Mar2026. The first occasion occurred on a winding mountain road enroute to a ski hill. The road was extremely busy at the time and pulling off was difficult and dangerous with only a small snow covered shoulder. The second occasion occurred on I-15 during rush hour. Again pulling across multiple lanes of traffic and stopping along the shoulder was dangerous. The dealer seems reluctant to do anything other than re-flash i.e. update the software again. A brief internet search demonstrates that often the software is insufficient to fix the problem.

2018 Pacifia developed a leak in the left bank head gasket. The vehicle only has 53,000 miles. From the forms it sounds like this maybe a common issue. So I am reporting the issue to hopefully help push the company to cover build or design issues. The gasket shouldn't break down a little past 53,000 miles. Thanks,
