2023 Jeep Grand Cherokee L

The starter/starter solenoid and related engine oil sealing have failed three times. Most recently on 6/18/2026, and previously in 2024 and 2025, the vehicle would not start: the dashboard illuminated but the engine would not crank. The engine then began smoking and a burning electrical smell entered the cabin. My wife and young child were in the vehicle. The vehicle was rendered completely inoperable and had to be towed each time. Safety risk: an engine that smokes and emits a burning electrical odor upon attempted starting presents a fire hazard to occupants. On the most recent occurrence the failure happened at a fuel station with my family present, over 1,000 miles from home, stranding us for seven days. Dealer confirmation: yes. On the two prior occasions a franchise dealer diagnosed a defective starter solenoid and replaced the starter. Both repairs failed and the identical failure recurred. On the most recent occurrence, a different franchise dealer found that a plug sealing an unused opening on the engine block was missing, allowing engine oil to spray onto and saturate the starter, destroying it. The starter and the plug were replaced. All failures were documented on dealer repair orders, which are available on request. Inspection: the vehicle has been inspected and repaired by franchise dealers on all three occasions. No police or insurance inspection. The manufacturer has been notified through its customer care department, which has open case records on this vehicle. Warning indicators: none. There were no warning lamps, messages, or symptoms prior to any of the three failures. The vehicle simply would not crank, followed by smoke and a burning electrical smell. This vehicle has spent approximately 60 days out of service since purchase and has had persistent electrical problems documented since 2023. Despite repeated dealer repairs the same failure mode continues to recur. I am reporting this as an unaddressed safety defect.

Computer telling vehicle to do a sudden unintended acceleration. Forward collision warning system did not respond. Air bags didn’t deploy. No diagnostics have been done. No warning lamps illuminated on dash. Vehicle currently is at repair shop. While pulling into a parking space at low rate of speed, vehicles engine reved up and vehicle took off, braking system did not respond unable to stop vehicle, hit a parking lot light post .

Electrical System: The dashboard and screen have repeatedly turned off, the windows have become inoperable, and numerous warning lights and messages have appeared, including alerts for night vision, front camera sensor, and service car. Climate Control System: The system blows inconsistent temperatures, ranging from extremely hot to very cold. It also gets stuck in windshield defrost mode regardless of the selected setting. This has caused dangerous fogging of the windows, obstructing my vision while driving. Drivetrain: The vehicle shakes and trembles, both at high speeds and at a complete stop. There is also a distinct abnormal sound coming from the driver's front side. These issues suggest potential problems with the axle, transmission, suspension, or a combination of these components. Potentially the Engine: The vehicle has experienced sudden acceleration issues while shifting gears, which could indicate an engine-related problem. Loss of Vehicle Control: The trembling and shaking, particularly at higher speeds, can cause a loss of control, increasing the risk of an accident. Unexpected Acceleration: The sudden acceleration issues while shifting gears could lead to unintended speeding and collisions. Impaired Visibility: The climate control malfunctions, specifically the extreme temperature fluctuations and persistent fogging of the windows, significantly reduce visibility and make it dangerous to drive, especially in inclement weather. I have been forced to pull over multiple times to clear the windshield due to the severity of the fogging. Distraction and Discomfort: The extreme temperatures blowing from the climate control system are distracting and uncomfortable, which can impair my focus while driving. Car has only been inspected by dealership. No there were no warning messages prior to the car starting to act up.

This vehicle has been making a noise in the front left side since new (day one). The vehicle has been taken to the dealership about 10 times in attempt to fix this issue. During the last service, the dealership performed multiple tests and concluded that the noise source is the engine motor mounts. If they disconnect the electrical plug of the motor mounts all the noises are gone. Consequently, they proceeded to replace the left front motor mount but unfortunately the noise is still there and concluded that there is no fix available right now. They understand that Jeep needs to redesign the motor mounts and update the software the controls the engine motor mounts. I know a few owners of the same vehicle that have the same issue. Jeep knows about it but doesn't do anything to redesign these parts in order to correct the design flaw. I can provide copy of the communications with Jeep if required.
