2018 Dodge Journey Electrical System Problems

I am reporting a safety concern involving a 2018 Dodge Journey SE (VIN: [XXX] ) related to a failure in the vehicle’s emissions control system, specifically the catalytic converter and oxygen sensors. On January 13, 2026, the vehicle began producing a strong sulfur or “rotten egg” odor while driving, and shortly afterward the check engine light illuminated. Diagnostic testing revealed trouble code P0420 (Catalyst System Efficiency Below Threshold – Bank 1). This code indicates that the catalytic converter is not properly converting exhaust gases, which can result in increased emissions and potential exposure to exhaust fumes. The vehicle was inspected by an authorized Chrysler, Dodge, Jeep, and Ram dealership in Maurice, Louisiana, which confirmed that the catalytic converter and oxygen sensors are failing and must be replaced. The vehicle remains available for inspection upon request. This vehicle was purchased for our growing family and is regularly used to transport our children, including a [XXX] infant and a [XXX] child. Since the emissions system issue began, occupants have noticed persistent exhaust-like fumes and strong sulfur odors while the vehicle is operating. Our infant has experienced recurring respiratory issues, and our [XXX] began experiencing respiratory symptoms after we purchased this vehicle. While we cannot definitively determine the cause, we are concerned that exposure to exhaust fumes from the malfunctioning emissions system may be contributing to these health issues. In addition, adult occupants have reported feeling unusually tired or fatigued after longer car rides in the vehicle, which raises additional concerns about potential exposure to exhaust gases inside the cabin. Because catalytic converter failures can allow harmful exhaust gases such as carbon monoxide and other pollutants to pass through the exhaust system improperly, we believe this issue presents a potential safety risk to vehicle occupants, p INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Back up camera failure cutting off and on. Could cause wreck. Dull headlights. Could cause a wreck.Leak in firewall driver floor wet. Could short out electrical system, cause shock, cause a wreck. No accident to report. This is ongoing since purchase in 2023.

The back up camera intermittently comes on when vehicle in reverse. Sometimes it shows a camera with a line, sometimes an image then it disappears and sometimes the image is hazy or distorted. It is never consistent nor reliable. The rear view mirror cannot be used to its full size because of the image of the failed camera.

There are known recalls on 2018 Dodge Journeys. For some reason my VIN [XXX] doesn't show on the list. 1) back up camera shows a black screen or a blurry dark picture (on going issue for over a year) 2) electrical system sometimes refuses to acknowledge the key fob and or won't start due to it thinking it has a dead battery. (on going issue for almost two years) 3) when braking in an emergency situation, heavy vibration from the rear of vehicle (on going issue for a few years when hard braking rarely occurs) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My back up camera has flipped the view upside down. Sometimes it glitches like static. I have tried different approaches to fix the issue but it continues to be upside down. It also caused me to back into my other car due to it glitching in the process of me backing up by causing me to lose visibility in a split second. It has been like this for years now with no hope of finding a solution. This is a safety issue and should be recalled.

The backup camera randomly works. When it does work, within minutes it slowly fades from a picture to a black screen.

Back up camera goes black

The cruise control has stopped working. And there is faulty wiring in the hood making the check engine light come on. And a huge water and oil leak we just got the vehicle Friday 2/21

At first,unknown, All problems are in the Tailgate,of which you cant see while driving. Tailgates are designed to be used. First ,the backup camera went out, then the third brake light went, and you can ONLY SEE when backing up to a Large picture window-also,parking light R/S in tailgate is out. NOW, I asked my granddaughter to open the tailgate when the car is LOCKED, and it OPENS- (Security) I then looked up on YOUTUBE, and found many on how to fix due to BAD WIRING at the hinge. A service repair ticket dated 11/21/24 from Bill Volz in westchester,NY noted immediate attention but did not see the rest items in need of correction. Security- Tailgate not locking Safety- multiple lights not working, Camera out,and windshield wiper /tail occaisionally --All connected

While driving on the freeway some of the lights on my dash kit up and all the sudden my car would not go over 15 mph. I tried to turn it off and turn it back on and it continued to do the same thing. I did have my grandkids in the car.

Lighting bolt with parentheses came on along with off road sign. I was unable to accelerate past 20 mph and then I just rolled to a stop in morning traffic with my flashers on. I took it to dealership and they replaced my key battery since I told them i was also having problems lock and unlocking my car. I was told this should solve the problem. It did for about 3 weeks now lights back on car won’t accelerate only till and it’s shaking bad.

The contact owns a 2018 Dodge Journey. The contact stated while driving 45 MPH, the check engine warning light illuminated. The vehicle was taken to the dealer, who diagnosed failures with the transmission, catalytic converter, and motor mounts. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 18V524000 (Electrical System), but the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 86,000.

***Radio system not working properly no longer connecting properly to phone, sounds muffled to the receiver on the other end of call, audio connect is not allowing me to be heard and I got a brand new updated phone! Thinking that was the issue. It wasn’t the phone, there was a precious recall regarding system updates issues, that I saw on here, but I was never notified about it!! *Audio hands free won’t map my iphone, to the car Bluetooth system will not connect at times, ****instrument panel lights are not showing, Radio goes off while driving often, not working properly, *****BACK UP CAMERA NOT WORKING PROPERLY: *Back up camera not working properly, noticed blurry, not able to see properly at night. ****Back up parking assist lines are not as bright and clear when backing up, image is no longer vivid! *Difficulty seeing behind you at night when Backing up, looks like snow on a tv screen ! ***off road system comes on by its self and stays on at times, car is serviced regularly!

All doors get stuck locked and/or unlocked. Key fob will not lock or unlock and door panels will not unlock our lock. 999 Back wiper only works intermittently.

Door locks Doors remain locked or unlocked. Key fob will not unlock or lock doors. Panel will not unlock or locked doors

The back up camera does not display an image. It will only show black, with a camera slashed out symbol.

It started with third brake light out, then,tail wipers intermittenly work, then camera not working- had to have someone watch the back of car to see also right inside light out AND Tailgate wont lock with rest of doors After looking on YOUTUBE this has been going on since 2012

The car will turn systems of the car off and own without anyone touching anything windows rolling up on their, traction turning off, and climate controls and A/C coming on by itself. I contacted Stellantis last year about this vehicle and received no substantial resolution. This exact thing happened when I owned a 2014 Dodge Journey and I submitted the same complaint. I have taken video of this occurrence, there is no way to demonstrate issue via still photo.

Failure of the back up camera to function while in reverse. Unit generally displays a blank screen although occasionally does work but image is extremely blurry.

A stall/no start condition situation occurred while driving, and has occurred a few times over the last couple of weeks. I have had the issue checked by a trusted mechanic, and it was suggested that the power control module(pcm) would likely need to be replaced. No warning lamps appeared prior to the problem, but appeared when the stall/no start condition situation occurred. The most recent occurrance of the problem was on Saturday, October 4th, 2023. I located on the NHTSA website that there is a recall listed, NHTSA Campaign Number: 18V524000, for replacement of the pcm. On 11/06/2023 I spoke with Chrysler support, according to them a recalibration of the pcm was done on 01/07/2021, and they will not support replacing the pcm because it has been more than 2 years. According to the customer rep, the unit was just recalibrated, and not replaced, but the remedy in the recall notice states that dealers will replace the powertrain control module, free of charge.
