2017 CHRYSLER PACIFICA Complaints

I purchased my 2017 in 2023. Within a few months, problems began. When we brought the van back to the Chrysler dealer to have it checked with their OBD2 code reader, multiple codes pulled up… First thing “needing” to be replaced was the hood sensor because the display said the hood was open (even though I was simply stopped at a red light). The auto start/stop light was also coming on and staying on. The dealer said that would go away after replacing the sensor. That repair was done (I believe) in April of 2024 at the Chrysler dealer (and the auto start/stop light came back on a week later, both batteries testing fine independently of one another). Next thing “needing” to be replaced was the accelerator pedal module because my van would start shaking, not accelerate, and go into (what I now know is) limp mode with all warning lights displaying on almost every right hand turn. This absolutely puts my safety and the safety of my four children at risk when it suddenly decides to not accelerate!! That repair was done in June 2024 at the Chrysler dealer. Next thing to happen is the check engine light illuminating. We checked the coolant and it was almost empty! This should NOT be happening! We filled with coolant, but have to do this every few days now. The check engine light has come back on and is still producing many codes, the worst of which is p0303. This code has pulled up every single time we’ve had the van scanned at the dealer. The dealer has had my vehicle on MULTIPLE occasions for MULTIPLE days each time and NEVER ONCE told me the severity of this problem. Their words: We just go down the list, starting at the top. P0303 was not at the top, and now I have to pay the price for their incompetency! My van would not start and had to be towed to the dealer yesterday, 7.17.2024. I’m waiting to hear from them, but I can guarantee this is a head gasket/engine failure issue. Who can afford to just replace an engine?! This is infuriating and beyond frustrating!!

The contact owns a 2017 Chrysler Pacifica. The contact stated that while children were exiting the passenger’s side of the vehicle, the passenger’s side sliding door came off track. The sliding door collapsed and was hanging. There were no warning lights illuminated. There were no reported injuries. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 130,000.

Before I purchased the vehicle the head gasket was replaced do to an misfire on cylinder 3 fault code. Misfire on cylinder 3 fault code consistently comes back on after replacing coil packs and spark plugs. Independant mechanic states he cannot solve the issue. Chrysler dealer states engine needs replacement as the block is cracked and leaking into cylinder 3. 120k miles on engine. Bought it with 112k.

The contact owns a 2017 Chrysler Pacifica. The contact stated while driving 70 MPH, the transmission position indicator started blinking while in drive(D), after which the vehicle lost motive power and was unable to accelerate above 40 MPH. The contact pulled over to the shoulder of the roadway and turned off the vehicle however, the failed to restart. The contact stated that the gear shifter was stuck in park(P). There was no warning light illuminated. The vehicle was taken to an independent mechanic, but the vehicle was not yet to diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown. The VIN was not available.

92,000 miles engine failed and had to replace with a new one. Started with a rough idle at start up and code said misfire on #6 ,had a tune up done with replacing plug and coil packs. Next code was #5 misfiring, and then it started blowing white smoke. Head gasket blown but wouldn't guarantee repairs so I went with a new motor with a warranty

2017 Pacifica, front bank (also referred to as left side of 3.6 Pentastar engine) multiple cylinder misfire, due to failed head; 110,000 miles. Issues progressed exactly or very similarly as described by multiple (hundreds of owners) on Pacifica forums), most fail between 80,000 to 120,000 miles, with distribution between 50k and 150k. Suspect excessive heat in engine bay coupled with defective head manufacturing (Mexican built engines suspected to have higher failure rate) and faulty components leading to head failures (cracked heads, warped heads, faulty head gaskets) on 2017+ Pacificas. Rear head known to fail due to lack of sufficient cooling in position at back of engine bay. Vehicle also goes through one aux start/stop battery every 1-1.5 years (suspect early failures due to excessive heat, not overcharging issue that Chrysler recalled for). Vehicle also has history of faulty roller rockers and lifters, already had replaced once while in warranty period. Issue began as faulty cam phase sensor. When repairs made mechanic also noted that oil cooler was cracked. This is a faulty design remedied by Chrysler for 2022 models. Heat coupled with bad o-rings and/or overtightening of oil filter cap leads to crack in assembly allowing for oil and/or coolant loss. Chrysler has made no attempt to fix known issue on pre-2022 models. Repaired both at cost of $1033. Few days later P0300 code and loss of engine power. Diagnosed as faulty roller rockers, one of which had even broken off. Roller rockers, lifters, and cam replaced on left side of engine at cost of $2700. Mechanic pressure tested head and found no leakage. Drove home and multiple cylinder misfire occurred again with loss of power. Returned to mechanic. Suspect crack between intake and exhaust valve guides which opens as head heats (seems to occur once engine reaches 195 degrees F, which is just below normal operating range). Head replacement suggested but not recommended as I'll be upside down in vehicle.

Failed head gasket. Faulty manufacturing. All maintenance done as recommended by manufacturer by the dealership who sold the vehicle.

I was driving the 2017 Chrysler Pacifica on [XXX] when the engine warning light came on and indicated that the engine was running hot. When I got home we checked and added engine coolant since it was low. Two days later the van was running hot again. I pulled over the engine coolant was empty. We refilled the engine coolant. Two days later the engine light came on and I took the van to our mechanic and he completed a partial tune up on the van and refilled the engine coolant. A few days later it began hesitating, jerking, and bouncing and the check engine light came back on. The temperature was reading okay. At home and when we opened the hood there was a very hot smell. When we opened the coolant and it began to bubble up then sucked all the liquid back into the van...somewhere. We left the engine cool completely overnight but the smell of burning coolant was seeping into our house all evening. In the morning we added more coolant because the tank was empty again. A few days it started all over again., loosing engine coolant, jerking, hesitating and bouncing. (I only drive the van 12 miles a day to work then 12 miles back.) This time I took it to our mechanic and he ran a diagnostic test and it found a cylinder misfired. He checked the coolant level and it was empty again. At this time he also checked the oil to be sure the coolant was not going into the oil tank but the oil was clear. He also double checked for recalls on the van and also on the spark plugs he had just replaced and but found nothing. He reset the engine light and we added 1/2 can of BG-44k fuel cleaner, part 208. The van ran smoothly for about five days. Then it began all over again. We then took it to a Chrysler dealership and was told the head gaskets were leaking coolant into the cylinder and the van needed a completely new engine! at a cost of $13,750! This seems to have been an ongoing issue with this model of van and Chrysler is doing nothing to fix it! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552

The contact owns a 2017 Chrysler Pacifica. The contact stated that soon after purchasing the vehicle, the check engine warning light appeared on the instrument panel. The contact had the vehicle towed to the dealer; however, once the vehicle was in the dealer's possession, the check engine warning light was no longer illuminated. Upon return of the vehicle, the vehicle jerked and hesitated upon the depression of the accelerator pedal with the check engine warning light intermittently flashing on the instrument panel. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 50,000.

The touch screen radio screen has blacked out in some sections making it difficult to use the backup camera.
