2018 Jeep Grand Cherokee: headlights failing or too dim

Filed Jun 3, 2026 · Electrical, Lights · IL

Headlight beams do not function. Beam lights come on upon starting car then turn off moments after. Then I am driving done the street in complete darkness. I have taken the Jeep to the dealership of purchase ( Elmhurst Chrysler/jeep/dodge Elmhurst Illinois 630‑834‑8000 ) 4 times over several months. They have confirmed the problem. Two days ago they had me replaced the battery. There was NO messages or other warnings that the lights have failed.

Electrical goes crazy when driving and parked , radio comes on, switches from AC to heat , on its own , calls people in my contact list , calls 911, screens goes blank at times , flashes on and off , heated seat on driver side gets way to hot , passenger seat ok so far , headlight keeps going out on passenger side fails to get it off heated seats at times or it freezes, it jumps from defrost to vent to floor , heat to AC , have to turn on AC when it rains to keep windows from fogging up. Hard to drive when it’s lighting up like a Christmas tree , radio won’t stay on same station , jumps from station to station , when on speaker phone it mutes the calls, or hangs up the person you are talking to. Navigation won’t work most of the time freezes up also.

The car keeps saying the turn signals are out when they all function properly. The car is equipped with the LED factory headlight systems. When it thinks the bulb is out it makes everything flash or turn off so other drivers can’t see your signal. Several other users are also reporting issues online. Dealer says the only way to fix is an entirely new head light assembly at $1300 since the turn signal bulbs are built into the headlight and should be a lifetime part.

The 2018 grand Cherokee has issues with mother board and electrical ghosts. 1st it was headlights and dome lights. they would flicker. i had to change the front lights 2x in a year. i thought this was odd. never did this with any car before. then I was driving home from work during rush hour and it started to rain. started the wipers front and back. the back wiper started and went halfway and got stuck. what happen? the front wipers went on for several revolutions (say 10-20 ) then stopped. started again. then stopped again. the rain intensity grew. Now the -wipers would only work when turned in opposite direction (the manual 1 pass move). this happened as i was trying to get home and stuck bumper to bumper on [XXX] . on this dangerous highway in middle of now a torrential downpour the front wipers now decided it wouldn't work AT ALL. i couldn't see anything and veered off to the shoulder thank god - waiting for rain to stop and then safely proceeded home. the next day the wipers worked. no check engine or anything. this goes on for a week or so with no issue. then out of nowhere the driver seat decides it has a mind of its own and pushes me all the way to the steering column. it wouldn't return when pushing the back button. i had to drive like that for my trip and then it magically went back upon restart. i take to dealer. pump motors bad on front and back. i say not sure your correct and explain. motor changed on front. not fixed. ok we think its the BCM. changed not fixed. finally the PDM was changed and wow it worked. 2 weeks at dealer and this shows that this issue with the control module is certainly risking peoples safety. i hope Jeep does the right thing and prevents a serious catastrophic event. read on the jeep electric issues and my vehicle had a previous "corrected" recall for Electrical Cruise Control. I dont think the fireware updates or software changes fixed all the bugs. be safe out there jeep INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FO

Driving home on dark, deserted roads, my brights will not click on. When I click, nothing happens. When I hold the turner back in the mode to “flash my brights”, the bright headlights will come on. I had to drive holding this back almost an hour so I could see. I had a mechanic look and he said the switch is wired to the computer, so it is not an easy fix, but will have to go to the dealership. This is a safety issue. Dealerships are far from me and expensive. I’ve never had this issue with a vehicle before, when all lights are functioning. It should be recalled and fixed by the manufacturer.

Brakes failed when attempting to slow down, ABS kicked in on dry blacktop with no lights on dash before locking up and throwing the vehicle off of the road. Caused me to wreck into a tree head on at 50 mph. Seatbelt did not lock up and airbags did not deploy. Vehicle was totaled with heavy front end damage including a bent and snapped frame. Prior to incident had issues with low beam headlights not working/going out prematurely. Was told by Herrenstein Jeep in Chillicothe this was not an electrical issue. Low beam headlights failed again 2 weeks prior to incident.

The computer system keeps intermittently saying the turn signal bulbs are out turning off the front signal when you want to use it. The bulbs are a bunch of LED’s in the headlight and it shouldn’t turn off all of them even if one is out (they are all working properly regardless). It seems to be a fault within the computer system either inside the headlight assembly or in the car.

Hi, I’ve noticed with this Jeep and the two newer cars before it would have my dash lit up when my headlights weren’t on. This is giving me and other drivers of these cars the false impression that my headlights must be on. So many folks are driving with either just fog lights or no lights at all because their dash is lit up. Before this technology your dash would be dim and that way you knew you needed to turn your headlights on. This is becoming so common I see 1-2 every day home from work. Before this new technology it was maybe 1 a year. Please research or ask around about this since there doesn’t seem to be regulation around it. Thanks very much!

Screen started to delaminate two years ago. Slowly started glitching. It now glitches constantly while driving. It randomly turns on and off, calls people, turns seat heaters on and off, changes channel, turns back up camera on and off etc. This is a major safety concern while driving. When I researched this online it appears to be a very widespread issue for all 2018 Jeeps. I have also had to replace my headlights 3 times in the last 1 1/2 years. I feel there is a correlation. I don't understand why Jeep is not recalling this issue.

2 Issue Related to Electrical/Lights: 1) The touch screen has delaminated. This started a while ago (appx. 2020) and was only an aesthetic issue until very recently. Appx. 3 months ago (3/2023) the screen started to have a "ghost button" where different things were being pressed. For example, music changed, seat warmers turned on/off, etc. The most dangerous of these issues was a dark screen turning bright, which can be blinding at night. Definitely a safety issue since some of the essential controls of the car are done here. 2) The "auto" high beams have stopped working (appx. 5/2023). They turn on when held with the "flashing" method, but when put into auto (where they stay on) they do not work. Certainly a safety concern.

On 1/15/23 I went back to start it again and it started, tried to drive away and the car shut off on me while driving. The car then began to honk randomly, all the wipers went off, and the lights started flickering. I turned the car off completely and tried ot turn it back on and the car would not start again and also the front left blinker was now completely not working and the front left headlight is completely out. There is a warning on my car for the front left blinker but not for the front right headlight.
