2019 Chrysler Pacifica problems

“I am reporting repeated electrical failures affecting my 2019 Chrysler Pacifica Touring, including recurring auxiliary battery failures, stop/start warnings, dashboard malfunctions and electronic shifter faults. Despite multiple dealership repairs, the problem continues. August 22, 2023: Auxiliary stop/start battery replaced under Mopar warranty at Jim Shorkey Chrysler, as documented in subsequent service records. August 26–28, 2024: Following another stop/start warning, Ferman Chrysler tested both batteries and found both failed load testing. The main battery was replaced and auxiliary battery warranty work was documented. September 8–9, 2025: Stop/start warning followed by electronic shifter malfunction. Ferman Chrysler confirmed the auxiliary battery had failed and replaced it under warranty. July 7, 2026: Jim Shorkey Chrysler documented previous starting problems and reported battery health at 78%. October 13, 2026: On starting the vehicle, the instrument cluster flickered repeatedly, and multiple warning lights appeared. A Service Shifter warning followed, and the rotary gear selector indicator lights stopped illuminating. Gear selection remained…”

“At 105,000 miles the check engine light came on, at which point the vehicle experienced rough starts and a rough idle. Vehicle also began emitting white/gray smoke from the exhaust upon starting. Upon diagnosis it was determined that coolant was leaking into #4 cylinder requiring head gasket replacement. Total repair came to $4,287.07. This is a known issue commonly being experienced by other Pacifica owners. This major mechanical issue is a safety issue and could easily have stranded my family on the road. We were fortunate to have been home and located near a known and trusted mechanic when the issue presented.”

“We are on a 5th! Auxiliary battery since purchasing the vehicle new in 2019. It fails every 1-2 years and it causes the main battery to drain as a result of it which means replacing both batteries on average every 18 months.”

“Almost got in 2 separate accidents because of a failed brake booster. No symptoms before hand to let me know anything was wrong. Came to a red light and the brakes became very hard to push and the vehicle proceeded to continue moving even though I hit the brake. It came to a stop in the middle of the intersection and I almost got hit. Also almost rear-ended someone because of the same issue. It has been confirmed at the Chrysler dealer that the brake booster failed. I have children and almost got into an accident twice because of it. Now I have to pay out of pocket because it got denied due to it being over the date of expiration. My vehicle has under 85,000 miles and now I'm out $700 because it won't get covered. It's a safety risk for me and my family.”

“When driving on the road and slight turning of the steering wheel from 11-1 o' clock position, the steering locks or gets stuck and I have to apply extra force to turn the steering wheel to get it to turn OK.”

“Our pacifica has repeatedly stalled on freeways. The engine will just stop running and will not start for 15 minutes to several hours. If it does start, it often will sputter and stall again if you try to put it in ear or press the accelerator. After some time, the problem will resolve itself and the vehicle will drive normally. This problem is infrequent which is what makes it so vexing. Each incident was more than 6 months apart so you never know when it will just stall out. Because our van was converted to a rear entry wheelchair van by Braunability we've had the conversion components/connections thoroughly inspected by the conversion company dealer. I can see online that this is a known issue with multiple vehicles equipped with the Pentastar V6 engine with stop-start and that there have been recalls but many people on the forum, the recall work didn't resolve the issue. We've had the vehicle to Chrysler dealers several times (four or five) to address the issue without permanent resolution. We've replaced the primary and secondary batteries several times. We've recently installed an aftermarket stop-start eliminator recently in the hope that it will resolve…”
