2020 Chrysler Pacifica

When driving on highway, electrical system started beeping and showing various signals, could no longer keep speed or accelerate. Had to put on warning lights and coast to side of road with four small kids in car. Was able to pull off to side and slowly get to safe location by resting vehicle in between events. When fully charged, didn’t seem to have issue so was able to drive to dealer. Thought was related to engine switching from electric to gas power. Dealer checked and performed two software updates. On way home from dealer, same problem occurred on highway. Super dangerous to loose all acceleration or same speed on highway! I got a video of second event as I was a passenger and my husband was driving. But as can see in video the car has a charge so the incident is not related to the switch from electric to gas power. Now we are very concerned whether Chrysler has the means to fix this at all and or whether the dealership will be actually able to identify the issue given the car was literally being driven home from the dealer. Attaching photos but have a full video. First time happened on April 4, 2026. Second on April 16, 2026

The contact owns a 2020 Chrysler Pacifica. The contact stated that while driving approximately 45 MPH, the vehicle started losing motive power. The vehicle stalled with the check engine light and several other unknown warning lights illuminated. The vehicle was restarted; however, the check engine warning light remained illuminated. The vehicle was taken to a local dealer to be diagnosed, and it was determined that there was an electrical failure in the transmission. The vehicle was not repaired. The contact stated that prior to the failure, the vehicle was repaired under NHTSA Campaign Number: 23V010000 (Electrical System, Hybrid Propulsion System); and associated the failure with the recall. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 113,000.

The contact owns a 2020 Chrysler Pacifica. The contact stated that while turning to the right, the steering wheel seized, and the vehicle became difficult to maneuver. The contact stated that force was needed to maneuver the steering wheel. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The contact stated that the failure persisted and became a worsening failure. The steering wheel seized while turning to the right or the left. The vehicle was not taken to the dealer or an independent mechanic. Upon further investigation, the contact became aware that the failure was most common with similar vehicles between 60,000 and 90,000 miles. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

Many times over the past 6 months the power steering assist goes away while driving at highway speeds. The steering wheel sort of locks up and it becomes difficult to turn. After much effort the wheel will turn and the steering returns to normal. It has happened at speeds as low as 40 mph and as high as 50 mph. This has occurred in heavy traffic situations. I have never had a dealer look at the problem. No warnings or messages from vehicle.

The hybrid propulsion system on my 2020 Chrysler Pacifica Plug-In Hybrid has repeatedly failed, resulting in sudden and complete loss of power while driving at highway speeds. The vehicle enters full limp mode, displays a red turtle warning light, and the motor cuts out entirely, creating a serious collision risk. The failure occurs without warning and has happened on multiple occasions. The root cause has been traced through escalating component failures: first the Power Inverter Module (PIM) was found to have an internal failure disabling regenerative braking and causing the motor to cut out; subsequently the battery charging module was found to be failing, causing the high-voltage battery to drain to 0% and stall the vehicle. Both components were replaced by an authorized Stellantis dealership under warranty. Despite replacement of the PIM, the charging module, and ultimately the transmission, the defect has not been resolved. The vehicle has been confirmed defective by the authorized dealer on each visit and has been subject to a STAR (engineering escalation) case with Stellantis. Warning symptoms include the red turtle warning light, check engine light, and sudden power loss. The vehicle has been out of service for cumulative warranty repairs exceeding 130 days, including a continuous period exceeding 90 days. The vehicle remains unrepaired and in dealer custody as of the date of this filing. The dealer has confirmed the defect on each visit and has conducted multiple rounds of diagnostic testing and component replacement, none of which have restored safe and reliable operation. The component failures are available for inspection upon request.

While driving in suburban traffic vehicle engine began running rough and lost most power with about 58000 mi on the vehicle. Received check engine light and vehicle entered 'limp mode' with Turtle Icon displayed on screen. Brought to dealer and it was diagnosed with a P0304 Cylinder #4 Misfire and leaking head gasket causing coolant contamination to engine oil. Dealer repaired the head gasket under warranty. About 2 months after the head gasket was repair at 60,098 miles while drive on the Interstate the engine began running rough. Check Engine Light came on and then Oil Pressure Light came on. We were able to exit the highway, had the vehicle towed to the same dealer where the head gasket was repaired under warranty. This time the engine was diagnosed with a failed #4 Cylinder connecting rod. Chrysler and Dealer refused to repair or replace the engine even though both leak and failure occurred on same cylinder.

This submission supplements my prior NHTSA ODI complaint regarding the same vehicle and loss-of-motive-power condition. On Nov 8, 2025, the vehicle experienced a loss of propulsion at highway speed, creating an immediate safety risk. The vehicle could not maintain speed and required evasive action with no propulsion to avoid traffic hazards. Following the incident, the vehicle was inspected and stored diagnostic trouble codes P0A3F-00 and P0A43-00 were retrieved, relating to drive motor position sensor / resolver signal loss or degradation. These fault codes are associated with loss of propulsion and indicate a propulsion control signal-path fault, rather than a condition resolved by software calibration alone. The vehicle remains available for inspection and is out of service at a dealership due to unresolved safety concerns. Since my prior ODI complaint, I provided formal written notice to the manufacturer describing the incident, the retrieved fault codes, and the safety implications, and requested a written response. Receipt was confirmed by USPS certified mail on January 6, 2026. No written response was provided, and repeated attempts to contact the manufacturer through customer service channels were not returned. The manufacturer authorized only a recall firmware update and declined to authorize or perform the intermittent wiring and resolver diagnostics identified in its diagnostic procedures for these fault codes. The firmware update does not inspect, repair, or replace the resolver, wiring, or related hardware indicated by the stored codes, and does not determine whether the underlying propulsion fault has been corrected. As a result, the vehicle has been out of service for more than two months, and the risk of another loss-of-propulsion event remains unresolved. This update documents the manufacturer’s non-response after notice and reliance on a software-only remedy that does not address the indicated propulsion system fault.

WHILE DRIVING DOWN MAJOR HIGHWAY, THE POWER STEERING LIGHT WENT ON. IMMIDIATELY MY POWER STEERING SHUT OFF AND I COULD NOT TURN WHEEL AT ALL. HIGHWAY WAS 55 SPEED LIMIT AND I COULD NOT EVEN PULL OVER. HAD VAN TOWED TO DAYTON ANDREWS CHRYSLER DEALERSHIP FOR DIAGNOSIS AND THEY TOLD ME THAT THE POWER STEERING MECHANISM NEEDED TO BE REPLACED AND IT WAS GOING TO BE $4,500.00. THIS VAN HAS 14,400 MILES ON IT. AFTER LOOKING ON LINE IF OTHER PACIFICA OWNERS HAD THE SAME PROBLEM, IT SEEMED THIS IS A GLOBAL PROBLEM. I OBVIOUSLY CANNOT AFFORD TO FIX THIS ALMOST BRAND NEW VEHICLE AND THE SALESPERSON INDICATED THAT EVEN IF I DID WANT TO FIX THE PART IS ON BACKORDER AND THEY DON'T KNOW WHEN THEY COULD GET THEIR HANDS ON THE PART. THE FACT THAT THIS PART IS ON SUCH AN EXTREME BACKORDER TELLS ME THIS PART IS IN DEMAND BECAUSE MANY PEOPLE ARE HAVING THIS SAME ISSUE. PLEASE HELP ! i AM GOING TO CONTACT MY ATTORNEY TO SEE MY OPTIONS. THIS VEHICLE IS BASICALLY NEW AND FOR SAFETY REASONS, BEYOND ANY FAULT OF MY OWN, IS UNOPERABLE.
