I took my vehicle in to have the computer reset as the recall fix required after my start/stop unavailable warning came up for the second time. First time I had to replace both batteries. About 6 months ago if that. Took it in with the check engine light having popped on saying it's a misfire. Then when we left the stop start failure was still lit up on the dash and there were more codes popping up including one for the shift module which is electronic.. so I believe the electronic system is causing the misfire. I don't even have 100,000 miles and my car is about 5 years old. (2017) We were traveling on a busy highway when the check engine light came on to start with and exited to turn around and head home when the van felt like it was getting sluggish and we luckily were not in the passing lane and were able to make it home safely.

UNKNOWN. Vehicle stalls out when attempting to start. If started vehicle can drive fine but when stopped at a light it stallls out from time to time requiring you to shut it completely off after putting it in park and restarting. At times it will fail to restart. There is no check engine light or anything for a shop to find the issue.

The vehicle is experiencing rough, late shifts when pressing the gas. The vehicle frequently lunges forward while your foot is steady on the gas pedal, feeling as if you have been hit from behind. It has 36,000 miles on it.

My Pacifica has random moments where the steering wheel feels really stiff while in motion. So stiff, It-??s on the verge of me not being able to steer! It also has random moments where the engine will stall while I am in motion. Sometimes when I press the gas to accelerate it will have a moment of lagging then it will abruptly shift into a higher gear. I-??m wondering if there is something seriously wrong and if I should stop driving it. I have four small children and I need reassurance that this vehicle is in fact safe. I-??ve been hearing and reading stories of other Pacifica owners dealing with the same problems with severe consequences.

Engine code p0303. Spark plug, intake plenum gasket, and coil replaced but still have the same code. Many other pacificas with the same engine have the same misfire problem that gets fixed by replacing head casket or engine.

- Des Moines, WA, USA

The engine overheated due to a coolant leak and faulty head gaskets that need replaced at 62k miles. A related cyclinder 4 misfire has been occurring since 58k miles. Chrysler refuses to cover the repair under the 60k Powertrain warranty and does not acknowledge the many reports of head gaskets failing between 50-80k miles.

While driving, the motor began to vibrate and lose power as if not firing on all cylinders, and acted as if it was going to stall in the lane of travel, causing me to have to pull off to the shoulder abruptly, striking a mailbox. The vehicle does not display any trouble lights or show any error codes on diagnostic equipment at an independent garage. Vehicle idles roughly.

- Clifton Springs, NY, USA

Symptoms: Rough Idle Check Engine Light Code: P0305 Cylinder 5 Misfire. Noticed the Coolant was low, and topped it off with distilled water. I've only owned it for a year and have had NO issues with overheating. The next day it wouldn't start. Towed to the dealer. Dealer replaced the starter and pulled out plug #5 and "coolant shot out of the spark plug hole". Dealers recommended service is Head Gasket replacement, with the possibility of head being re-surfaced or complete engine replacement. I was lucky the vehicle was in my driveway when it failed to start. It appears this exact scenario has happened to at least 50 other folks active in a single online community at 60,000-80,000 odometer miles (mine is at 74,000). So I believe this situation is much larger.

The 2017 Pacifica will sometimes have a lack of power when trying to accelerate, and/or will jerk or shutter. Other times, mainly when the engine is warm, it will shutter and die when starting the engine. Sometimes it will take two or three restart attempts for the engine to remain running. In one instance in slow moving stop and go traffic the vehicle stuttered and then accelerated toward the car in front and I had to slam on the brakes to prevent a collision. The vehicle has been back at the dealer multiple times and they claim there are not any codes they can use to diagnose the problem. Even when the engine dies it does not cause the check engine light to come on. When they scan the codes they usually find P0171 and P0174, but they say the codes are not active, only stored. I am told the vehicle is current on all power train software but the problem is still occurring almost daily.

Vehicle was misfiring, took it to the mechanic said it was the 3rd cylinder. Had that replaced, but the vehicle continued to have problems. It lost power while driving but I was able to maneuver it off the road. Took it back to the mechanic where he stated the head gasket had busted. There was no sign or indication of the vehicle overheating or anything prior to all of this.

I was driving on the highway when my vehicle began to shake and became undriveable. Before this incident I had brought the vehicle to the mechanic for a check engine light showing that there was a misfire and coils needed to be replaced. The coils and spark plugs were replaced but on this day the misfire caused the van to shake on the highway before becoming undriveable. I could not pull over and was left in the middle of the highway unable to drive my vehicle. This created a huge safety hazard as cars were driving by at 55mph and I could not pull over to the shoulder then had to wait for a tow truck. I then had this problem fixed for the 3rd time when on my way home from work today 8/11/22 the van once again began shaking, check engine light came on and misfiring, luckily this time it was as I pulled into my driveway. There was no warning, the check engine light appeared as the van began to shake right before stopping and locking up. This problem has been confirmed with a dealer. The dealer said the issue was the first mechanic used -??after market parts-?? however when I spent the extra money to have the -??factory-?? parts put in by the dealer, the problem also occurred. So I spent additional money to have the same result.

Stalling and loss of power, the car computer reader code is P0305. 5th cylinder misfire, and a P0300 cylinder misfire. 2017 pacifica with 62,000 miles and there are tons of people with the same issue around the same mileage. Funny how the drivetrain warranty ends at 55,000 miles and all of these Pacificas are failing at 60,000 - 80,000 with blown headgaskets or bad cylinders. $2000-$12000 depending on what blew.

I have a blown head gasket and my car has been in the shop for over 3 months because the part is not available. The car has never overheated. I'm so frustrated as I know this is a known problem with these cars. The car is at the shop, sitting in pieces because of the lack of parts available.
