2017 Chrysler Pacifica: check engine light

Filed Nov 5, 2026 · Engine · LA

I experienced the red turtle light on a trip to [XXX] two weeks ago. It was intermittent, it would come on and go off within about 5 seconds total. I realized the fire hazard risk recall had not been completed. Upon returning home I took my vehicle to the dealer. At that point I did not have a cel illuminated just the red turtle light intermittently. They had returned the van to my possession saying it was fixed. I drove the vehicle for about an hour and once again got the red turtle light and no Cel. I immediately texted the service manager at the dealership with a video of what it was doing. No Cel light only intermittent red turtle. Now fast forward to today. The dealership says the van needs a HV battery heater to the tune of over $2,000. It now has the red turtle and and the cel illuminated. This battery heater has been an extremely common issue for the pacificas and the jeeps with the hybrid drivetrain (essentially the same). There needs to be some sort of recall for this issue as the problem is common among pacifica and jeep owners with the hybrid drivetrain. P0E15 code is active currently. I have attached pictures showing the red turtle and no cel. Service manager says the cel is currently active on the vehicle along with the red turtle.

The contact stated that the vehicle occasionally shut off while driving at various speeds. The "Check Engine" and "Shift to Park" messages were displayed with an audible chime. Due to the failure, the contact was forced to pull over and restart the vehicle to resume normal driving. The vehicle was taken to an independent mechanic, where a code for an unknown sensor was retrieved. The contact reset the computer; however, the failure returned several days later. The failure mileage was approximately 128,000.

This occurred on [XXX]. I was driving with two passengers heading west bound on [XXX] in Ohio and starting to go off an exit ramp. The passenger side power window went down without anyone pressing a button. I pulled up on the driver-controlled passenger window switch to correct the window, and it went up. But, either immediately upon going up or shortly after (I don't remember), the van experienced a series of electrical faults. The CEL came on, I start hearing warning chimes, the infotainment screen rebooted. I heard a clicking noise from under the hood, which I later learned was the parking pawl trying to engage. Dash screen said something about "speed too high to shift to park." Momentarily the wheel jerked hard - I think I lost power steering (if the car fully shut off I think that's what happened). I gained control and directed the car to the side of the road. I don't know what state the car was in at this point - either fully off or electrically on but no engine power. In any case, I shifted to park, pressed the on/off button and the car fully shut down. After a couple of minutes I attempted to start the car again, and it started right up with no issues. The CEL was lit, but the car drove fine. When I got to my destination about 20 miles away, I checked the battery terminals. I found that the negative terminal could be turned about a quarter turn if I used some force, but it was not what I would consider 'loose'. I still tightened the connection as much as I could, to the point that the connection was now immovable. The CEL cleared after a few cycles of turning the car on and off. A scan later showed that code P1B14 was stored. I called multiple Chrysler dealerships and each told me that they could not diagnose the problem unless it was actively acting up. The car has not malfunctioned since the incident four days ago. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Under safety recall 73B, for which I had the software update done last year (nothing noted by the dealer). I have since had intermittent check engine light issues, and even had the vehicle completely shut off last winter for 10 minutes in the middle of the road. It subsequently turned on, and when brought in I was told there were no "current codes" in the system to investigate. I've now had check engine light on steady for a couple months. There are historical codes U029A-00 (lost communication with hybrid battery pack sensor module), U0412-00 (invalid data received from battery energy control module A), and current code P1D43-00 (internal control module shut off test monitoring time error). With these relating to the battery pack control module ("BPCM") and hybrid control processor, it is quite apparent that there is an issue with the BPCM and that the lack of communication and errors on the shut off test monitoring that the BPCM is malfunctioning which could cause a number of issues, such as a fire per safety recall 73B. I was told by the manufacturer that there is a 2-year period to remedy safety recall work. As this was a software update, it would appear that the software is now identifying a potential danger with the BPCM. Per that recall "...A folded or torn anode tab may result in the generation of lithium by-product over time. This defect, along with a second unidentified factor, may lead to an internal short within the pack and may result in a vehicle fire. A vehicle fire may increase the risk of injury to occupants and persons outside of the vehicle, as well as property damage. " Without proper communication (as stated earlier), I expect that my vehicle is still at significant risk. However, the dealership I've brought it to is requiring me to pay for battery pack replacement and has charged me a diagnostic fee. This while they have labeled the issue a "failed high voltage battery". My request for recall coverage was dismissed.

One year ago (114k miles) I started having some rough idle, stumbling, etc. Then a cylinder 5 misfire code appeared. I swapped around coils and injectors, replaced the PCV valve, replaced lower intake manifold, coolant flush. Still no improvement. So I then replaced all the coils, plugs, and bench cleaned and tested all of the fuel injectors and reinstalled them with new o-rings. Misfire code kept returning. On Veteran's Day last year on our way back from a parade it would barely go over 35 mph with the CEL flashing. I limped it straight to the dealership. For context, I have never run the vehicle hot and have kept up on regular maintenance intervals. I gave them a detailed list of everything I did to the vehicle. They had it in the shop and did a compression test. Compression was good on the cylinder head for 1, 3, and 5. However, a leak down test was performed and showed a significant leak in cylinder 5, prompting the need to replace that cylinder head. Luckily, we still had our extended warranty and this $10k job was completely covered. Fast forward to a month ago (126k miles) I was getting a noise from the accessory drive area. After looking closer, I had to replace the serpentine belt. In order to do that I had to remove the lower radiator hoses and drain the coolant. Got everything back together and started it up. The noise I previously heard was louder and more like a chatter. Then a cylinder 4 misfire code appeared. I tore it down, looked at the plugs and coils. All checked out. Did a compression test and compression in all 3 cylinders was good at #2: 155 psi, #4: 151 psi, #6: 153 psi. Ibwent ahead and replaced fuel injector for that cylinder. Vehicle has been running for a few weeks and is still registering misfires for cylinder 4. Everything is pointing towards a cylinder head replacement, which will cost upwards of $10k, just as the previous cylinder head replacement did. This is a far too common problem on these engines.

The contact owns a 2017 Chrysler Pacifica. The contact stated that the check engine warning light was displayed on the instrument panel soon after the vehicle was purchased. An independent mechanic replaced the EVAP purge valve, but after the repair, the power steering assist failed, and several unknown warning lights were illuminated. A mobile mechanic attempted to clear the codes, but the power steering failure persisted. The vehicle was then towed back to the independent mechanic, where a diagnostic test provided several fault codes, including electrical, ABS, brakes, traction control, rack and pinion, and the check engine warning light was displayed. The vehicle remained with the mechanic unrepaired. The dealer and manufacturer were notified of the failure but provided no assistance. The failure mileage was 107,000.

I keep getting check engine lights and they have repaired serval of the items and I did get a letter in the mail saying the battery would now have a lifetime warranty if it threw a certain code and I had two codes come up and some people told me to replace my 12v battery and it would probably clear up. so reset the codes and put new battery in and ran fine for a week or so (I don't drive much) then when I got in the other day and had it fully charged and it showed on screen only 69% and I thought that was strange then the check engine light came on again showing code P0A0A high voltage system interlock circuit so I am really worried the battery is having a problem and needs replaced. Will it be covered under the lifetime warranty? I see on safety recalls that these vehicles were recalled??

My 2017 Chrysler Pacifica experienced repeated engine timing and oil system failures. The vehicle first developed a check engine light and engine timing code (P000D – camshaft position slow response). The vehicle was inspected by a dealership service department. Shortly after, a major engine oil leak was discovered from the oil cooler / oil filter adapter assembly. The vehicle required repair of the oil cooler assembly and associated seals. After that repair, the vehicle continued to experience engine timing issues. The dealership later confirmed failure of the cam phaser components associated with the engine timing system and performed a repair. Within days of the repair, the check engine light and engine timing code returned again. The failure involves the engine valve timing system and oil pressure dependent components based on Autozone code check. Improper camshaft timing can affect engine operation, cause loss of power, rough running, or possible engine stall while driving, which creates a safety risk in traffic. The issue has been inspected and confirmed by a dealership service department. The vehicle is available for inspection upon request.
