2020 Chrysler Pacifica PLUG-IN Hybrid

I received a service hybrid electric vehicle system warning. Also vehicle speed may be limited warning. When I shut the vehicle off, it was loud and remained running. My safety and the safety of others were put at risk because the warning happened while I was driving and I couldn’t get speed to park in a safe location. I had my car towed to a local Chrysler Jeep Dodge dealer and they updated software related to my car that was the source of the problem. They also told me the battery completely drained. The recall was due to a faulty PCM that the recall was for. You can see in the invoice the problem I communicated to the manufacturer before they diagnosed my vehicle. You can see clearly the vehicle was still active even after shutting off, likely causing the battery to drain completely. And due to the faulty PCM, it failed to tell the systems to shut down. Chrysler is giving me $100 for the tow. But they say the battery is out if basic warranty so will not reimburse me the $650 or so for the battery. My argument is that it doesn’t matter if the battery is out if basic warranty as the draining of it was a direct result of the recall and failed PCM. There is case law that supports the fact that If a recall-related defect (such as a faulty PCM) directly causes a secondary failure (e.g., battery damage), the manufacturer still bears responsibility, as the defect rendered the vehicle unfit for normal use.

While driving, the vehicle spontaneously goes into limp mode and warns the driver to pull over immediately because it is about to shut down. This has happened at least 10 times in my ownership of this vehicle since 10/04/2023 and the first time on 10/09/2024 and most recently occurred 07/06/2024. The first time it occurred on a narrow mountain road at night but I was safely able to drive slowly for about a mile before finding a parking lot to pull over. Several times were significantly more dangerous and occurred while traveling 70mph on a busy interstate and forcing us to navigate across several lanes of traffic into the emergency lane in a vehicle that is no longer able to keep up with traffic due to significant power loss when limp mode. Once pulled over, the vehicle must be turned off for several seconds before restarting and driven again. Occupants are at significant risk of being involved in a collision during the entire process from unexpected power loss, navigating traffic with said power loss, parking and restarting the vehicle on the side of a busy road, and attempting to safely merge back into traffic which is often traveling 70+mph. This entire issue is due to a faulty wiring harness in the transmission of 2017-2023 Chrysler Pacifica Hybrid that can short circuit and requires immediate shutdown of the vehicle when it occurs. Thus far the only remedy from Chrysler is a software update which installs a driver warning to pull over and restart the vehicle before it shuts down instead of immediately shutting off. This is marginally better than complete power loss but still poses significant increased safety risk for passengers and surrounding vehicles and a remedy that stops the failure from occurring in the first place needs to be implemented immediately. This has been known to effect 70,000 vehicles from 2017-2023 year models and the fact that a remedy to the actual problem has not yet been made is appalling and dangerous.

Dealer said the transmission needs to be replaced. 2020 Chrysler Pacifica Hybrid Limited (Certified) purchased in August with 28,500 miles. Bought the 7 year/100,000 mile extended warranty. Happened on Interstate 495. Chrysler Care was a joke. Wanted info filled out ONLINE. Ask for the zip code and couldn't go past that point. Finally called and waited on hold for 40+ minutes. Hell of a time trying to tell where I was on the interstate. I was almost directly under an overpass, told them the name of the overpass street and they kept wanting to put me on THAT street. Sent coordinates from Google Earth and they put me on the other side of the interstate going in the other direction. 😡 To make a 3-hour story short tow truck finally came and we got it to my dealer. Codes did say something about the transmission but the manager couldn't tell exactly. Now waiting for the service tech to call on Monday. Oh, BTW, no loaner available (even though it's covered in the warranty). The dealer called and paid for a Lyft to take us home.

Twice now the A/C has quit, and a short time later the Hybrid battery severely overheats and the van shuts down. This happens at highway speeds, and the vehicle loses power and shuts down. This is dangerous to have a sudden shutdown at 75 MPH. When driving in hot weather for a couple hours, the electric A/C compressor quits. On this van, the Hybrid battery is cooled by the passenger HVAC system. When the A/C quits first you feel the air from the ducts getting warm. Then you get a message on the dash for "Battery Conditioning" and a Check Engine light. If you keep driving, it stalls and will not restart until the battery cools off. It takes about 3-4 hours to get the van to move again at reduced power. If you let it cool overnight, the van drives normally until the next incident. There are trouble codes set for battery overheating, P0A7E, P1AA6, P1A9A, P1A21, P1AA2, P1A9E. There have been multiple unsuccessful attempts to diagnose the van by Chrysler dealers. Dealers can't/won't replicate this due to having to drive for approximately 2 hours in high ambient temps. The vehicle is fine in moderate or cold temps due to not needing the A/C to cool the battery, it is cooled and heated by secondary systems in those conditions. This issue is very dangerous because lithium batteries do not like extreme high temperatures, this issue could cause a thermal runaway event of the battery. Many of the codes that were set are for the battery temperature exceeding 131F (55C), which is severely hot for Li-Ion. This is much hotter than safe high temp recommendation for Li-Ion. Recall 03A for not giving warning before stalling was performed, however this issue is not the same symptom, nor the same cause as that recall. That recall involves a transmission short, not battery overheating. My van has had multiple reflashes and is up to date on all software. My vehicle was a "lemon law" buyback for the same stall issue, and was purported to have been fixed before I purchased the van.

The contact owned a 2020 Chrysler Pacific. The contact stated while entering the vehicle unknown warning lights illuminated, and the contact shut down the vehicle and restarted it. When the contact restarted the vehicle, the contact noticed that the engine was running rough and shut down the vehicle. When the contact exited the vehicle, it roll backward on its own and rear-ended into a fence causing damage to the fence and damage rear passenger side bumper. No one was injured. A police report was filed. The vehicle was towed to an unknown place. The manufacturer was not contacted. The failure mileage was 27,000.

Was driving the vehicle and all of a sudden the vehicle lost ability to accelerate. Warning of "Service Charging System" appears on the dash and the "D" indicator starts blinking. Warning of "Shift to P to Start" appears and check engine light comes on. I tried to shift to park and restart the vehicle, but it did not do anything. I was on a decline, so was fortunately able to coast into a parking lot. This is the 5th time this has happened while driving the vehicle. There is no warning that it will happen and it is extremely dangerous for the vehicle to lose all motive power without warning. I was lucky to not get rear ended. The vehicle has been serviced at a dealership two times for this same issue.

Driving on the road and vehicle lost all propulsion. Warning comes up on the dash saying Service Charging System and Shift to P. At that point, one has to coast to a stop on the side of the road. Vehicle would not restart. After waiting and completely shutting down the vehicle, it did restart. This is the second time this has happened over the past two months. The dealer updated software as a "fix" the first time, which has not fixed the issue. It also happened a third time when pulling into the dealer for service today. Dealer was able to see the issue. It is extremely dangerous, as there is no warning before losing all propulsion and it can happen at any speed and at any time. Please note that this appears to be the exact same issue addressed with NHTSA recall 22V-865, and both vehicles are manufactured by FCA and likely use the same hybrid electric powertrain. By addressing this loss of propulsion issue in the Chrysler Pacifica Hybrid now, there is a chance to save lives (there was a death caused by the Jeep 4xE recall issue) by mandating this same recall for the Chrysler Pacifica Hybrid.
