2021 JEEP GRAND CHEROKEE Power Train Problems

REPEATED CAM SHAFT FAILURE. THE VEHICLE HAD A SUDDEN LOSS OF POWER. THIS HAS HAPPENBED THREE TIMES IN THE LAST 12 MONTHS. IT IS CURRENTLY AT A STELLANTIS DEALERSHIP IN MICHIGAN. THERE IS USUALLY N O PRIOR WARNING. THE CHECK ENGINE LIGHT COMES ON AS SOON AS THE ISSUE STARTS.

35000 miles 4 wheel drive transfer case went bad. Company honored full repairs. I was the second owner of this vehicle.

Transmission failure at 19,481 miles in my 2021Jeep Grand Cherokee Limited 4x4 V6. The vehicle has not been abused, and the mileage is low for its age. The symptoms—erratic shifting, limp mode, and “Service Transmission” warnings— are consistent with a known defect pattern affecting multiple FCA vehicles using the same transmission.

I believe it is something with the engine or an electrical component. I was driving and as I was parking my car shut off, was not able to completely park back end of the car is sticking out. I looked up if there were any current recalls using my VIN and nothing appeared. I did my own researching and found that there have been recalls for that model regarding the PTU, Power Steering and Power Loss which is the issue I am experiencing. My car turns off on its own and does not get any type of power. Started having trouble turning on my car over Labor Day weekend was not able to travel due to what I thought was my battery having issues, people were jumping me to be able to start my car. I then had my battery tested at O'Reilly's on 9/3/2025 and when trying to jump...

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the ESC and “Service 4WD” warning lights illuminated, causing the vehicle to shake abnormally. Additionally, the transmission unexpectedly shifted to 4WD Low while driving. The steering wheel vibrated while making a turn, and the vehicle jerked. The vehicle also intermittently failed to start immediately and made a clicking sound. The vehicle was taken to an independent mechanic, who determined that the ABS had failed, and that the drive train control module and transfer case control module needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,000.

This Car have a lot issues we the computer in the car, the car I was missing oil in the engine ,the piston. Blows out No light 💡 engine On the car have a lot problems we trans mission No light On,I Have problems we transfer Case No light on, Now still having problems if backups sometimes is No light on,I don’t know if Normal but if have a lot safety concerns in this car.

Vehicle shifts from park to drive jumping gears ,making loud noises, Accelerating by its self and jumps aggressively into gear. Transmission is slipping, late engagement when shifting, and shifting rough. sometimes it will low rpm. Rpm is going up and down. Making total transmission failure and transfer case failure. Melting the hot and cold lines. Mechanic found aluminum melted and oil burn. Rpms fluctuate and gets hung up during shifting while driving.

Service shifter message keeps showing every-time I turn on the vehicle. Eventually it just stays on. Took vehicle in for service and when dealer was installing new shifter, it shorted out other components. Jeep still hasn’t found a permanent fix.

Vehicle code: C1562-98 AIR PUMP CONTROL - air suspension compressor is overheating or there's a problem with the control system, leading to issues with adjusting the vehicle's height. With further inspection he found a leak in the air bag fittings. Vehicle Power Control Module has caused vehicle to shutoff while driving on the highway. Air suspension and electrical issues continued after 60 days of attempted repairs.

Once you start driving after letting the vehicle sit the transmission will “slip” multiple times jerking the car and everyone in it. Occurs every day around 4 pm and various times

The car have a lot of problems engine total failure, mounting joints failure, acelere by him self, jerking,,while driving vehicle kicks aggressively in to gear, oil cup broken down make in the engine to blow oil over , no oil in engine. Sometimes missing 3. Quarters of oil because the seal of the engine no last , is a lot problems in this car

Since it was brand new it likes to shift hard into reverse or drive from park. Sometimes it shifts with NOTHING going on like it should Other times there is subtle thump into gear other times it's a harder thumb into gear. There is 2 or 3 levels of hard shift into gear. Valve body and Output shift kit have already been replaced and it's STILL happening

I was driving down the highway and all of the sudden and with zero warning the engine cut off but the effect it had on the car was very severe engine braking as it automatically downshifted very aggressively which caused me to go from about 80mph to a stop VERY quickly. The dash looked as if I simply had the car switched to on without starting the engine. There were no warning lights lit. Shifting into park and turning the car completely off and back on allowed it to start again with no further symptoms.

I drove my car out of my garage on the way to work and just outside my house, the transmission bucked when shifting from 3rd to 4th gear and the p0733 code appeared. I turned around and went home and took another car to work. I had previously taken my jeep with ~85,000 miles to my local dealer wanting the 4 wheel drive and transmission service as I do with all of my cars. It was driving fine, but seemed like the gas mileage was decreasing a bit which I shrugged off. The dealer informed me that the transmission wasn't serviceable. I thought this was odd, but they did the 4 wheel drive service and said everything was good. When I got the error code, I called my local independent transmission shop who said they could look at it in 2 days, so I didin't drive it until the ~10...

The electronic stability control has malfunctioned and the 4wd svc light has comeon. The vehicle shifts hard when taking off at low speed. When coming to a stop there is a loud pop from transfer case. Also the 4wd low and neutral comes on by themselves. This vehicle definitely has safety issues. I just bought this vehicle and just barely have 1000 miles on it. How is thus safe? The hard shifting started around 6/1/2024 the electronic stability, svc 4wd, going into 4wd low and neutral all started on 6/23/24

In 2022 I attempted to back into a parallel parking space and the emergency braking system kept activating to prevent backing up. Attempted getting corrected at dealer but no trouble codes available. Was driving, slowing down to stop at about 22mph, emergency braking system kicked in, shifted into auto stick, switched back reactivated normal drive. Six months later, was at a stop sign, on green light, turned left from left lane, accelerating to approximately 25mph, suddenly emergency braking activated again, again had to use auto stick to kick out of emergency braking. Luckily car behind me was not tail gating. end of message 04:56-Fri-01/05/24

Started noticing hard reverse shift when vehicle was cold. Took to the dealership, tech could not find any issues other than it shifted hard in reverse. Tech found no leaks, performed PCM reflash. Still no problems found. Tech did not check transmission fluid level on vehicle. Must be checked at the dealership. Tech recommended replacing transmission even though could not find any issues. A few days later while driving at highway speed the vehicle suddenly downshifted to 3rd gear nearly causing me to loose control. Vehicle would not shift into fourth gear. Had to limp vehicle home.

Driveshaft became loose while driving

The vehicle turned off once while driving and the check transmission light comes on periodically. l took it in for service, however, the dealer was not able to find the problem. Since leaving the repair shop the check transmission indicator comes on while driving and turning.

Paddle shifters are disabled with no way to enable them. While towing, there is no way to reduce downhill speed maximizing the use of the power train while minimizing the use of the brake system causing the brakes to overheat and a potential crash incident.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that after accelerating from a stop light and driving approximately 45 MPH, the wheels locked up causing the vehicle to abruptly stop, and the vehicle stalled. After restarting the vehicle, the failure immediately reoccurred. The vehicle was later towed to the local dealer however, the cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 11,000.

We were stopped for redlight at busy multilane intersection, light turned green, went to accelerate vehicle revved to over 3000 rpms but would not shift out of first gear, got to side of road put vehicle in neutral and then back into drive and was able to proceed. Took vehicle to Chrysler Jeep Dodge dealer service center after doing diagnostic they did computer update; they then got a diagnostic code to replace transfer case. The vehicle did this again about 3 months later took it to dealer they did diagnostic unable to find anything. Vehicle did it again about 2 weeks later took it to dealer and they performed a computer update. This is a very dangerous situation when vehicle will only barely move at busy intersections, and you are in a middle lane and can't get into and outside lane and off the road in a timely manner. When...

Turning the car on, there was a failure of our power steering and the steering wheel was not functional. Check engine light and power steering error lights came on. After turning car on and off, we were able to drive (check engine light remained on) to a dealership. They performed a software update that Chrysler released in Oct 2022. This is the second time this has happened to us (first in April 2022, car had to be towed), there are forums of similar issues for this model. Dealer was able to pull the codes and said they have seen other similar instances of this issue. "We cannot guarantee this won't happen again" it was physically inspected and did not see any obvious issues. This is absolutely a safety issue and should result in a recall in my opinion if it is a known issue that is a safety hazard.

While in gear if would not go. Within the first 5,000 miles it was in the shop twice and had to have a new transmission installed. Drove it for another 5-6k miles and same thing happened again and dealership is saying it will need another transmission.

What component or system failed or malfunctioned, and is it available for inspection upon request? *radio, sound, bluetooth connection, dashboard, entire screen of radio, navigation, speakers, transmission slipping occasionally - yes it was available for inspection How was your safety or the safety of others put at risk? screen often updates itself while driving or the screen and dashboard turn completely solid white or black, preventing me from seeing speed, navigation or anything at all.

Has the problem been reproduced or confirmed by a dealer or independent service center? YES Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? inspected by the original dealership Were there any warning lamps, messages or other symptoms of the...

The contact owns a 2021 Jeep Grand Cherokee.

The contact had the vehicle towed to a dealer after the second failure; however, the mechanic was unable to duplicate the failure. The contact also stated while going downhill at low rate of speed, the vehicle independently downshifted twice without warning, which brought the vehicle to a near stop. The contact stated that the vehicle lunged forward with her foot on the brake pedal with an abnormal cranking sound coming from the transmission. The manufacturer was not notified of the failure.

My 21 Jeep Cherokee shipped from Detroit Stellantis HUGE cover up FLOOD car. My JEEP is 8 mons new. I leased it 12/7 contacted Uconnect on 12/13 for Powertrain Malfunction indicator light on.

They stated door was open still locked out, stranded multiple times, car will not start. Dealer has...

The transmission was slamming into gears while attempting to accelerate onto a road way from a mall parking lot and any time we met a hill of even the smallest incline, the transmission would be slamming gears again so we struggled when met with needing to accelerate. When attempting to accelerate, transmission began slamming into gears, would and wouldn't shift, transmission would go into limp mode rendering the vehicle unable to operate safely and causing us to loose speed. Any inclines we would lose the ability to accelerate and would hope we'd make it up the hills. Any time I attempted to accelerate, the transmission would begin jerking the car in a forward and backward like motion while it was attempting to find what gear it needed. When that would happen, the tack would jump all over the place as would the gear number on the dash (I have video...

In March 2022 my wife was driving down a street in Arizona on her way to work when she heard a pop and the car stopped accelerating. She managed to get the car into a neighborhood and pulled over. I picked her up and left the car there. Eventually I was able to get it towed to the dealership at which point the service advisor told me the transmission needed to be replaced. The car only had 2,900 miles on it. I requested that Chrysler buy the car back knowing it was defective but they said the car does not qualify for a buy back and they ended up giving us a 1 month payment and fixed the card under warranty. In June 2022, my family and I were on vacation in California traveling north on the I-5. The car made a faint noise and several lights came on the...

I started driving through an intersection after sitting, stopped at a traffic light. I stepped on the gas pedal and the car wouldn’t move. It made a loud reviving noise but wouldn’t go anywhere for about 15-20 seconds. I put my hazard lights on and sat for a few more seconds and then put it in park, and then back into drive. I was able to pull onto the median of a very busy road. My vehicle was brought to the dealership who said there’s nothing wrong with it 🤔

The contact owns a 2021 Jeep Grand Cherokee. The contact stated while performing a routine maintenance on the vehicle, she was informed that the vehicle was emitting an abnormal sound. The vehicle was taken to the local dealer where it was diagnosed that failure was associated with the transmission. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 28,000.

This is my second attempt to get someone to reach out. I have a 2021 Jeep Grand Cherokee L with approximately 3100 miles. This vehicle has been in the repair shop a minimum of 10 times. Power steering goes out at times while driving. This vehicle falls into the Lemon Law. I have been unable to reach anyone at Jeep Headquarters to assist with resolving this buy back. No one has returned my calls. This is a very serious safety concern

This vehicle had a new complete transfer case after owning 3 weeks was in the repair shop for approximately 1 month. 1 week later power steering goes out. back at the dealership. Power Steering goes out again get back 1 day and Power steering goes out as I am driving. Back to the Dealership. 3 x power steering goes out. Now says a repair has been done. This week transmission and interior lights possibly going out. Car purchased new November 4, 2021 has less than 3000 miles on it. Has been in the repair shop approximately 3 months of the 4 months its been owned. This car actually scares me to drive it because I never know what's going to happen.

2/18/2022, I was driving down Bethany and 75 in Allen, Texas when my vehicle made a sputtering noise then the gears went out. Could not engage the gears to Drive or Reverse. I coasted the vehicle to the church parking lot where I sat for 6 hours waiting on a tow truck. When tow arrived, vehicle's brake and parking break had to be pushed down to allow vehicle to go into neutral. Vehicle would turn on, but the ac/heating system did not work, radio was shorting out and vehicle remained locked in Park. Check engine light came on after the sputtering and did not turn off. Vehicle was serviced the previous week at Dodge City McKinney with no reported issues of this caliber. Per dealership, codes are showing issues with the transmission and engine. Vehicle only has 9347 miles and if I had been on a major highway, I could...

VECHICLE WAS PURCHASED ON 11/6/21 ATT SMITHHAVEN JEEP IN NYS. THE NEXT DAY I NOTICED SUBSTANSIAL CONDENSATION IN BOTH THE HEAD LIGHTS AND REAR BRAKE LIGHTS. I TOOK THE VECHICLE TO THE DEALER RIGHT AWAY AND THEY STATED "ITS NORMAL AND IT WILL GO AWAY", THAT BEING SAID I STILL HAVE THIS ISSUE AND IT HAS NOT BEEN RESOLVED. ON APPROX 12/13/21 THE VECHICLE'S RADIO FROZE AND I WAS UNABLE TO USE IT FOR SEVERAL DAYS. A MESSAGE PROMPTED ME TO CALL SIRIUS XM RADIO, HOWEVER THEY STATED IT WAS A VECHICLE ISSUE AND NOT A SATELITE RADIO ISSUE. I LOOKED UP ONLINE AND FOUND HOW TO HARD RESET RADIO AND I HAVE TO DO THAT OCCASIONALLY TO CLEAR THE UNRESPONSIVE RADIO. THE MOST RECENT ISSUE WAS A COMPLETE TRASMISSION FAILURE ON 2/1/22. WHILE ATTEMPTING TO MOVE VECHICLE THE TRANSMISSION WOULD NOT GO FORWARD PAST THE 1ST GEAR AND WOULD...

my wife was driving. SUV was doing about 50 mph on highway. With left hand she hit the paddle shifter on the steering wheel. SUV went from auto trans mode to lower gear manual mode. Engine jump up in rpms, had to pull off road, stop car, restart car to get back into auto trans driving. This 2021 Grand Cherokee L has no way to disable the paddle shifters if you do not want to use them. This driving change can happen anytime, local or highway driving. You need to have them come up with software fix to disable paddle shifters.

Front Drive shaft broke off vehicle while driving at 45 mph and lost control of vehicle. Vehicle is available for inspection. The vehicle lost control and almost flipped over when the drive shaft broke off. Problem was confirmed by dealer. Manufacturer has not inspected vehicle they had the dealer send pictures. No warning lights appear on dash before or after the incident.

Vehicle was in park on the drive way and rolled backwards about 20 feet before coming to a stop. Video from Ring camera is available in the link below. https://photos.app.goo.gl/QjvPBfN47gBhqLA37

Second incident in less than 2 months on Grand Cherokee L that has 2K miles. Vehicle experienced limp mode when stabilizer system malfunctioned when going 45mph. Began to stall and lost acceleration. Gas pedal was unresponsive. Second incident (~500 miles later) Power Steering Failure. Could not get vehicle out of garage. Luckily this malfunction did not occur on the highway. Was able to get it to dealer the next day and they fixed with software updates for only the effected power steering module. What other updates are needed and what happens if the braking system is next? I have lost all faith in Jeep’s ability to design a safe and reliable vehicle for my wife and 2 kids. My wife has anxiety driving her own car as well. The roll out of the L and Grand Wagoneer may be coming with potentially fatal flaws.

Vehicle was left at dealer on 12/3 to address the infotainment screen gltiching and turning off and to address a recall. The dealer performed a software update and addressed the recall. I picked vehicle up on Saturday, 12/4. The infotainment screen flashed off again and I noticed the transmission shutters and bangs during a downshift and when I lift off the gas pedal. It was observed on Sunday, 12/5 that the nightvision images freezes and glitches while using.

Rough shifts from 1st gear to 2nd gear. When making a a full stop transmission does hard kick.

During the first 3,000 miles of owning the vehicle, on 3 separate occasions, the vehicle has failed to shift from first to second gear, appearing to get stuck in neutral. Because this is occurring when the vehicle is first beginning to accelerate this is happening when entering intersections, changing lanes, and crossing lanes causing the vehicle to rev while either coasting (due to the positive motion prior to shifting) or sit motionless when on-coming traffic is approaching. The only way to get the vehicle back in motion is to completely stop the vehicle (irrespective of the dangerous location) put the vehicle in park, then back in drive, and try accelerating again in hopes that the vehicle will shift on a second attempt. One one of the three occasions so far, this occurred while exiting a parking lot but before entering a changing lane on a busy street. On another occasion...

Car does not down shift properly from 5th to 1st gear or shifts hard into upper gears causing the car to jerk or jolt into gear. The Sport mode engaged the steering becomes sloppy loose and car becomes unstable to maintain control, unless returned to auto mode. Dealership techs claim they cannot diagnose because the computer system does not show any error codes the repairs they have done are computer updates which were supposed to fix the transmission issues it did not. FCA Stellantis refuses to acknowledge the problem and has told the dealerships to not pull the car in for any work unless they can show computer code failure or they will not compensate the shop for any warranty work. Jeep knows there are many issues involving this model including engine shutting down while in motion and again refuse to warn Jeep owners this particular model puts them at...

On three separate occasions on the same trip, the engine simply shut off at freeway speeds, requiring me to navigate to the shoulder. This was extremely dangerous as there was no propulsion control to avoid other traffic and no warning that it would happen. This is a brand new car with under 3,000 miles. No warning lights came on and all gauges were at normal range. When placed back in park, the engine restarted. Research reveals that for many years Jeep and Chrysler vehicles have displayed similar problems, resulting in numerous recalls and many Lemon Law lawsuits. The dealer has the car and is conducting an inspection.
