2019 Chrysler Pacifica brakes problems

Filed Aug 27, 2026 · Brakes · IL

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.

The brake booster has failed, a hissing noise is audible coming from the brake pedal when depressed. I have also noticed reducing stopping power in certain situations. It appears this issues is referenced by Chrysler in an extended warranty, covered under Mopar Warranty Bulletin D-22-15, however this car has now been in service for 6 years.

The vehicle’s braking system is not working properly. The brake pedal pumps and does not always respond correctly when pressure is applied. When backing up, the brakes pump and do not stop the vehicle as expected. While driving forward, the vehicle may continue moving even after the brake pedal is pressed. Because of this, I have to begin braking much earlier than normal and stop farther back from stoplights and other vehicles to allow enough distance for the van to finally come to a complete stop. This issue puts the driver, passengers, and others on the road at risk because the vehicle may not stop when expected. It has been extremely scary, we stopped driving the van. The exact cause is UNKNOWN but the BREAKS for sure.

I have had an issue with my brakes for a couple years. I have taken my van to a couple of different mechanics to express my concerns and they have changed brakes but the issues continue. The brakes do not always work effectively. They make a hissing sound. When my foot is on the brake, sometimes my van will still roll forward or backwards - this has happened often when leaving parking lots. I cannot stop quickly when animals or unexpected moments happen while driving on the highway. I have not yet had an accident due to this but this condition is very serious. There was an extended warranty issued due to this issue (brake booster) but it was issued prior to these issues occurring in my vehile and has expired. The issues are still very dangerous. I encourage this warranty coverage to be extended further.

During normal driving from office to home car suddenly started stuttering and I was apply break but speeded up and showed engine light on, I was about to hit front car due to additional speed. During that time I saw few quick messages on the dashboard, the one that I can remember was related with ACC. That's the dangerous situation. I looked d from OBD and found that code was U0412 and reported that code to Huntington Beach Chrysler service station. Please keep an eye out for some similarities between others reports.

Component failute: first the cruse control would stop working while driving. then the engine would rive way up while trying to accelerate and not gain much speed, gas mpg dropped. when breaking to stop i had to push the break pedal harder. when the cruse had stopped and i shut the engine off, it was hard to start, and would bump and shake as if it was hitting on 2 cylinders, cruse still would not work. after i made it home, the next time i started it, it was ok, then the last time i parked it the brake will not depress and it will not start. battery has 12 volts, jumped it anyway break still want depress. took battery cables off shorted them together , did not help. break pedal still will not depress.
