2017 Chrysler Pacifica fuel system problems

Filed Oct 1, 2026 · Fuel system · ND

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.

On 8/16/26, my 2017 Chrysler Pacifica Hybrid would not start after being parked for several hours in an underground parking structure in downtown Detroit during a baseball game. There were no warnings before the failure. The vehicle was towed to Serra Lake Orion at a cost of about $700. The dealer found diagnostic trouble code P0AA1 (hybrid/EV battery positive contactor circuit). The high-voltage system is locked down and the vehicle cannot be started or driven. The vehicle has been at the dealer since August 18, 2026, and as of 10/1/26 has been out of service for about 6 weeks. The dealer has an open Chrysler STAR technical support case (102974656) seeking approval to replace the high-voltage battery, and the process has involved repeated requests for additional testing. I have been given loaner vehicles during this time but am approaching the mileage limit on the second. The vehicle has about 220,000 miles and I have owned it since August 2017. It has no open recalls. It previously received recall repair work on the hybrid system, including the power inverter module recall (Chrysler T34 / the federal safety agency 17V‑371), which included reprogramming of the battery pack control module. I understand this model has also been subject to other high-voltage battery recalls. I am reporting this because a high-voltage contactor failure that leaves the vehicle unable to start or move can strand occupants, in this case in an underground parking structure, and because the repair has been delayed for more than 6 weeks. The root cause has not yet been determined by the dealer or manufacturer. I would appreciate the federal safety agency tracking this failure alongside other Pacifica Hybrid high-voltage battery complaints.

While driving at highway speed, my 2017 Chrysler Pacifica PHEV suddenly entered limp mode, displaying a red turtle warning light and red battery icon, and lost propulsion. My family was forced to pull onto the shoulder of a busy expressway, creating an immediate safety risk to occupants and other drivers. The vehicle was towed to an authorized Chrysler dealership where it has remained for nearly four weeks. A wiTECH scan confirmed the Battery Pack Control Module is showing as unprogrammed. A second scan three weeks later confirmed the BPCM remains unprogrammed and three active DTCs are present. The dealership has confirmed these findings but is attempting to release the vehicle in this condition. Records show Recall 03A for loss of motive power was previously performed on this vehicle. The same symptoms have recurred, suggesting the recall remedy may not have been effective. The dealership is denying warranty coverage while refusing to program the BPCM that would confirm or deny that coverage. Stellantis customer care has closed my case twice without resolution. I have formally refused pickup on safety grounds.

My 2017 Chrysler Pacifica Hybrid entered limp mode and was taken to Central Florida Chrysler Dodge on XXX. The service advisor, [XXX], identified three recalls, which needed to be completed, after claiming they had completed them, the issue persisted. I authorized a coolant flush without being informed it involved the battery cooling system. Further diagnostics revealed a failed hybrid battery. However, Chrysler denied the battery replacement claim, citing contamination from “incorrect” coolant. I dispute this reasoning, as I was not properly informed about the coolant issue and believe there is no proof that it caused the battery failure. Under the Magnuson-Moss Warranty Act, a warranty or recall claim cannot be denied without clear evidence linking the fluid to the failure. I have opened a case with Chrysler (Case #XXX) and am requesting that the battery replacement be honored under the recall, especially since recall guidelines indicate that unresolved issues after software updates may require component replacement. After a days of back and forth, not the dealership claims the PIM is not the original part of the vehicle and for that reason it would be covered under warranty. However the law is clear and Chrysler is obligated to replace it since this part is also part of the recall they claimed was completed. Now the dealer wants US$ 5K to replace the PIM. I need the federal safety agency to intervene please. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I experienced a check engine light and intermittent starting issues with my vehicle (Chrysler Pacifica Hybrid 2017). [XXX] At times, the vehicle would not start, but after some time it could start again. After researching the issue online, I found that there are active safety recalls for this vehicle related to the hybrid system (including battery and inverter/PIM). I immediately contacted the dealer: [XXX] An appointment was scheduled for April 1, 2026 at 4:00 PM. I dropped off the vehicle at approximately 3:50 PM and handed over the keys. Prior to visiting the dealer, I purchased a diagnostic subscription tool to better understand the issue, as many owners report dealers misdiagnosing these problems. The diagnostic results indicated issues related to the PIM (Power Inverter Module), including required updates and possible internal diode failure. This matches the symptoms I experienced, where the vehicle would intermittently fail to start. I have attached photos showing error messages related to PIM update and hybrid system faults. On the next day, the dealer informed me that they would only perform a diagnostic for $180 instead of processing the issue under recall. I believe this is incorrect, as the symptoms match known recall conditions (loss of power / hybrid system failure), and recall-related diagnostics should not be charged to the customer. The dealer is refusing to proceed under recall and is attempting to charge for diagnosis. This is a safety issue and should be handled under recall.

This is a complaint regarding an inadequate recall remedy for Recall Z75 (the federal safety agency 24V‑538). The manufacturer's software update rendered my 2017 Pacifica Hybrid inoperable due to DTC P0C77. While the battery was ultimately replaced under warranty, the manufacturer is refusing to reimburse $1,948.74 in rental expenses despite a prior verbal commitment to do so. This constitutes a failure to provide a 'free and effective remedy' as required by federal law for safety recalls.

We bought this vehicle from a local dealer in March (9months ago) in the time we’ve had it… it’s been in the shop for about 6 of them. 1- About 3 weeks after the purchase it shut off while I was driving on the highway. We then took it to the dealership in Jasper, Ga bc the error code said the pcm needed to be reset. They couldn’t get it to reset so they embarked on a diagnostic that took 3 months to discover the fuel pump was “too small”. The dealership repair guy assured us this was a solve to the issue, they’re tech put 200 miles on it an had no issues. 2- The day we got it back the check engine light came on and while going around a curve to the right, the wheel locked up on me and almost drove me into a mailbox. We turned around and went right back to the dealership. They had it for another couple weeks and told us we needed a new rack and pinion. We couldn’t afford the $6000 they wanted to fix that. So we then called the guy we bought it from and he had a local repair shop take a look and they replaced some parts on the rack and said it was good to go. 3- got it back and the check engine came on again, they code said pcm needed to be reset. We couldn’t get the dealership to call us back so we went to the local shop o’reileys recommended and they deducted some gauges needed to be replaced. 4- within a couple weeks the van was sputtering and cutting off again, we took it back to the local shop and the only thing they could think to do was change the auxiliary battery. 5- we’ve had it for about 2 weeks… 2 days again I went to start it up and it cut off. I had to wait a few minutes to try again and it started. Then yesterday while driving we stopped a red light and something popped and the dash lit up with errors and a grinding noise started. We went to accelerate to turn and started rolling backwards while in drive. We slammed on the brakes, turned the cautions on and put it in park and still rolled backwards. We had to get a tow back to the local shop.
