The engine hesitates when accelerating from a stop. Especially while turning. This happens 100% of the time. If you are accelerating very slowly, then no issue. However this is not common. The hesitation has resulted in several near accident situations.

ELECTRICAL SYSTEM, ENGINE
New 2026 Jeep Grand Cherokee (2.0L turbo I4) has open, unrepaired safety recall 26V-559 (FCA 54D): the tire pressure monitoring system may not detect low tire pressure or illuminate the warning telltale; remedy is an RFH module reprogram. The vehicle also has an open manufacturer campaign for 2.0L engine spark plug replacement and additional software flash campaigns. I scheduled service for these recalls at an authorized FCA/Stellantis dealer (Larry H. Miller Chrysler Jeep Dodge Ram, Boise, ID). I dropped the vehicle off on a Wednesday at 7:00 AM; the dealer kept it nearly 4 full days and returned it Saturday evening with zero recall work performed, citing shop scheduling delays. The service advisor told me to call/email the following Tuesday to reschedule; those calls and emails were not returned. Voicemails and emails to the dealership's service manager and general manager have also gone unanswered. As a result, I am driving a new vehicle with an incomplete safety recall and no dealer remedy scheduled. No crash, fire, or injury has occurred. Problem has not been inspected by the manufacturer. I have escalated to the manufacturer and am attempting to book the recall at an alternate dealer. I am reporting that the manufacturer's dealer network has failed to remedy this safety recall in a timely manner.

NEW SAFETY INCIDENTS – [XXX] – PREVIOUS COMPLAINT ON FILE I am reporting additional serious safety concerns involving my 2026 Jeep Grand Cherokee Limited Reserve, purchased new on [XXX]. Since purchasing this vehicle, I have experienced repeated bucking, jerking, rough engine operation, hesitation, loss of power, and stalling. On [XXX], the vehicle completely stalled. On [XXX], it nearly stalled while traveling through a busy intersection with my granddaughter in the vehicle. The vehicle was at Douglas Jeep for approximately 24 days, from September 23 through October 16, 2026. The dealership replaced all eight spark plugs after discovering excessive oil or unburned fuel contamination on the plugs. Despite these repairs, the dangerous drivability problems continue. During a recent test drive, Douglas Jeep General Manager John Grupe personally experienced the vehicle bucking and jerking at low speeds. On [XXX], I experienced additional concerning vehicle movement. After shifting into reverse while backing out of my driveway, the Jeep moved backward at approximately 4–5 mph without my foot pressing the accelerator. When shifting into drive, the vehicle also moved forward without accelerator input, reaching approximately 5 mph and maintaining that speed until I applied the brakes. I recorded video evidence of these incidents. The vehicle continues to buck and jerk severely at low speeds, including while maneuvering, turning, and driving through parking areas. I am particularly concerned about pedestrians, children, and other motorists. Despite multiple repair attempts and approximately 30 days out of service, these problems remain unresolved. I have repeatedly notified Stellantis and the dealership about the continuing safety concerns. I am requesting that NHTSA document these new incidents in connection with my previous safety complaint and evaluate whether these recurring drivability problems represent INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving approximately 65-70 mph on a highway, my 2026 Jeep Grand Cherokee 4x4 with approximately 15,000 miles suddenly jerked to the right and a loud knocking/clunking noise was heard from the drivetrain area. Immediately afterward, vehicle performance decreased significantly and the vehicle struggled to accelerate. The sudden loss of power at highway speed created a safety hazard due to surrounding traffic. No warning lights or messages appeared. The condition persists and the vehicle continues to have acceleration problems. This was very unsafe because either myself or other couldve been injured. I called jeep and they told me to drive it in to the Dodge dealership in Andrews TX, I want to emphasizes this is very unsafe, because it wont accelerate as it should. I have to drive down a road that oil tanker semis drive on as well.

"I am filing this supplemental report to provide critical new technical information regarding a 2026 Jeep Grand Cherokee Limited Reserve. This vehicle has experienced recurring engine instability, including rough idling, jerking, bucking, and loss of power. Most critically, on September 22, 2026, the vehicle nearly stalled while traveling 25–30 mph through a busy intersection, creating an immediate and severe safety hazard. Following this incident, an extensive investigation by Douglas Jeep, Stellantis STAR technical assistance, and a manufacturer engineer revealed oil contamination inside the engine cylinders and on the spark plugs. This is a recurring issue; the spark plugs were replaced prior to the vehicle's delivery in August 2026 and were replaced again in October 2026. Despite the involvement of a Stellantis engineer, the manufacturer has failed to provide a diagnosis of the root cause of the oil contamination or a permanent repair. The vehicle has spent approximately 30 cumulative days out of service since August 17, 2026. I am reporting this as a systemic mechanical failure that poses a significant risk of sudden power loss during operation."

driving down the road at any speed, the jeep will stop on a dime like you applied the full brake and shut off. i this has occurred 4 different time almost causing 2 bad accidents, one involving an unloaded log truck on hwy 130 in nc and the other one on hwy 544 in sc. The other two were while trying to accelerate out onto the rd. All this occurs without any warning. The engine will race quickly up to 35mph making rpm go to 7, the dash will go completely red when pulling off at red lights. I refuse to drive it thru a small town where people cross at, Jeep has been reported back to dealerships for all the same reoccurring problems since 130 miles.. Spark plugs replaced 2, elec parts been replaced , nothing is fixing the problem. MB Jeep is where i purchased the Jeep. Will not hold a speed, it will control speed itself. I took it back Saturday to dealership, bc I refuse to get killed or kill anyone else with all these problems. I was also told that my jeep of the 26 model engine change out was no the only one. All of them are coming back in with major problems.

On September 22, 2026, at 1,445 miles, my brand-new 2026 Jeep Grand Cherokee suffered a sudden powertrain failure and almost stalled in a live traffic intersection. The vehicle experienced an active loss of motive power with no dashboard warning lights. I drove it immediately to Douglas Jeep, where the Service Manager scanned the vehicle and found active fault code P032F-00 (Insufficient Engine Torque) stored in the computer. The vehicle was grounded the next morning, September 23, 2026. Authorized technicians confirmed liquid engine oil intrusion into the cylinder head had flooded the main chamber spark plugs. This manufacturing defect causes sudden engine hesitation and loss of motive power in active traffic, creating an imminent crash hazard."

My 2026 Jeep Grand Cherokee has experienced repeated engine shutdown and braking-related failures while driving. The vehicle is currently at an authorized Jeep dealership and is available for inspection upon request. On May 17, 2026, while driving to Fair Oaks dealership due to an unusual engine noise, the check engine and brake warning lights came on. The engine then shut off while I was in the roadway, and I experienced loss of normal braking ability. I was frightened but managed to move the vehicle safely to the side of the road without a collision. The dealer inspected the vehicle, replaced the spark plugs, and returned it on May 29. I later received a recall notice involving the spark plug issue. I returned the vehicle to the dealer on September 11, 2026, and the recall/service work was completed. On September 23, 2026, while driving to work, a similar dangerous failure occurred again. The check engine light came on, the engine shut off while the vehicle was moving, and I again experienced a braking problem. I was terrified but fortunately managed to stop safely. The vehicle was towed to the authorized Jeep dealership. The dealer inspected it and told me the problem was related to the auxiliary battery and repaired it. The problem has therefore occurred more than once and has been inspected/repaired by an authorized Jeep dealer. Jeep Customer Care has also been notified under Case #98217351. To my knowledge, police and insurance representatives have not inspected the vehicle because no collision occurred. I have not picked up the vehicle because I no longer feel safe driving it. An engine shutting off together with braking problems while the vehicle is moving creates a serious risk of a crash, injury, or death to me, my family, other motorists, and pedestrians. No one has been injured so far, but I believe we were extremely fortunate. I request that NHTSA investigate this repeated safety failure.

I purchased a new 2026 Jeep Grand Cherokee Limited on August 31, 2026. Immediately after taking delivery, I discovered that the vehicle’s Assist and Automatic SOS services were not functioning. The Automatic SOS system does not connect to the required service, and these safety features remain unavailable. I reported the issue to Jeep Customer Care on September 1, 2026. Since then, I have worked extensively with Jeep Customer Care, the assigned Case Manager, Jeep’s technical team, and the dealership to resolve the problem. The issue was escalated to Jeep’s technology team and, according to Jeep representatives, to AT&T as a Critical Safety concern. Jeep has specifically classified this matter as a Safety Issue. The dealership inspected the vehicle and confirmed the issue. A Star Case was also initiated at the direction of Jeep Customer Care for further investigation. Despite these efforts, I have now been dealing with this issue for 23 days without a resolution or definitive timeframe for when the safety-related services will be restored. I have been advised that there is no estimated timeframe and that resolution could take days, weeks, or potentially months. I have also been told that Jeep considers this issue unique to my specific vehicle and that it is not affecting other like vehicles. I purchased a new vehicle with the reasonable expectation that all advertised safety and emergency-assistance features would be operational at delivery. After 23 days, these critical services remain unavailable. Given Jeep’s own classification of this matter as a Safety Issue, I am requesting an immediate and appropriate resolution, including replacement of the vehicle with a comparable new vehicle in which the Assist and Automatic SOS safety services are fully operational.

The contact owns a 2026 Jeep Grand Cherokee. The contact stated that the vehicle was idling roughly, shuddering while turning, and hesitating while accelerating. The failures had occurred approximately three times. The contact stated that while his wife was driving approximately 15-20 MPH and attempting to merge onto the highway, several unknown warning lights illuminated, an alarm sounded, and there was an abnormal burning odor, prompting the driver to pull over to the side of the road, where the vehicle lost motive power. The vehicle was restarted after several minutes and operated as intended. Additionally, the contact stated that while making a left turn onto a street, the vehicle stalled, nearly causing a crash with oncoming traffic. The contact promptly shifted into Park (P), restarted the vehicle, and continued driving. The contact also stated that while going through a car wash with the gear shifter in neutral(N), the Auto Park mode engaged, and the vehicle was almost rear-ended. The car wash was shut down, and the vehicle was pushed with assistance before being restarted. The vehicle was taken to the dealer twice; however, the contact was informed that no trouble codes were retrieved. The spark plugs were replaced under an unknown recall, and the shuddering ceased temporarily, but the failures persisted. The failure mileage was approximately 357.

The vehicle repeatedly bucks and jerks during acceleration, including at approximately 5 mph in parking lots. It also runs roughly and has demonstrated unexpected forward movement. These problems affect the vehicle’s ability to accelerate and operate smoothly and may create a safety risk near pedestrians, parked vehicles, other objects, and surrounding traffic. On XXX, at approximately 4:49 p.m., in a parking lot in [XXX], and with the vehicle at approximately 1,181 miles, I shifted the vehicle into Reverse. The Jeep shook severely and stalled. After I restarted the Jeep, it ran very roughly, continued bucking, and jumped forward unexpectedly. This created a potential risk of striking another vehicle, pedestrian, or object in the parking lot. The vehicle also continues to buck and jerk at approximately 5 mph in parking lots, creating an additional risk of unexpected movement near pedestrians, parked vehicles, and other obstacles. On XXX, at approximately 6:22 p.m., I contacted Jeep Customer Care and reported that the vehicle had stalled when I shifted into Reverse and that it ran very roughly after restarting. The manufacturer case number is XXX. I previously reported the bucking and jerking condition to Jeep dealerships.

Jeep is violating federal recall mandates under Case #97911550. My 3-month-old vehicle was grounded at the dealership for two mandatory safety recalls, and the dealer had no loaner cars available. While my third-party rental stayed well under the company's $60 daily cap, Stellantis has refused to fully reimburse the mandatory, non-discretionary state fees (New Jersey Domestic Security Fee and Vehicle Recovery Fee), as well as an uber transportation cost to retrieve a third party loaner, leaving me with a $58.20 out-of-pocket balance. The manufacturer has failed to provide a zero-cost remedy as required by the National Traffic and Motor Vehicle Safety Act despite several requests for them to do so.

2026 Jeep Grand Cherokee Limited - Once I shut down engine, when I opened the door to exit, it started beeping at me. After a few minutes looking around to make sure I hadn't left a door open or something, I thought maybe it hadn't registered that it was in Park, and Shut Off. I pushed the "Start" button, and the dash had a message "Ignition On". When I tried to put it in Reverse, it moved on it's own back into Park, and again displayed "Ignition On". I tried putting it in Drive, and the "D" just flashed at me and finally moved back to "P". I'm not sure exactly when this was displayed, but there was a message at one point that said something about the "Start/Stop" function, but it wasn't visible long enough for me to catch what it said. I called my son who came over and we troubleshooted (I was afraid to remove my foot from the brake due to other horror stories I've heard about, so I sat there for several minutes with my foot on the brake waiting for my son to hopefully know what to do). Once he was there, he asked me to slowly remove my foot from the brake. When I did, he could feel the Jeep trying to move forward. After some other testing/troubleshooting, he asked me to lock the door and see what happened. I did so, waiting a few minutes and turned it back on. This time it worked as expected and started. I'm driving this car all the way to Texas next week, and I'm terrified (especially now that I see ANOTHER recall - that's 3 since I bought the car 60 days ago) that something horrible is going to happen! I do not feel safe in this car, and I just spent ALOT of money on it!

This engine does not run smoothly, it jerks coming out of a stop so there is delayed acceleration and it jerks every time you change gears. So I am almost rear ended at every stop light and stop sign. It also can lose acceleration or fail to accelerate on highways.
