Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
***68375577A$ is not showing the correct verbiage please update and correct*** Clunking when going over bumps, potholes, or turns. During diagnosis dealers may find rubber separating from the bushing on the handling link (SOL S2102000004 Rev C. for reference). This is normal and most likely is not attributed to the noise. Please follow normal diagnosis and ensure all tie-rod and ball joints are properly torqued and if worn, replace. If diagnosis leads to lower control arm replacement, the tension link(s) should be replaced first then test driven to ensure noise has disappeared before any handling link replacements.

The failure pattern owners describe
The rear coil spring detachment is the dominant failure mode in this cluster. Sixteen complaints describe springs dislodging from their mountings—sometimes while parked, sometimes at freeway speeds (40–71 mph reported). Owners hear a pop or scraping noise, then notice the rear sag noticeably. The springs eject intact, suggesting a retention problem, not material failure. Multiple owners completed NHTSA Recall 23V413000 (Chrysler Recall 64A) for the same issue, yet springs detached again—one owner's spring popped off 13 days after dealer repair. Not all 2023 Grand Cherokee L VINs are included in the recall despite identical failures.
One owner reports accelerated inner tire wear at 15,000 miles blamed on the air suspension, with alignment confirmed correct.
Additional suspension troubles include persistent front-left clunking that dealerships traced to motor mounts, an unsolved cracked rail, and a rear strut found on the ground. One owner's left rear tension link bolt sheared, damaging the knuckle, axle, and tie rod.
Dealership communication has been inconsistent: some refuse to provide repair paperwork, claim original parts were used instead of updated ones, or deny coverage for out-of-warranty coil spring failures.
Failure modes owners describe
Rear coil spring detachment/ejection
Rear coil springs dislodging from their mounting position, either while parked or while driving. Springs ejected intact without fracture, indicating retention failure rather than material weakness. Multiple reports of springs coming loose even after recall repair (Recall 64A/23V413000) had been completed.
When: Ranging from ~46,000 to 60,000 miles; failures occur both parked and while driving at highway speeds (40-71 mph reported)
Symptoms owners cite: Loud pop or scraping noise from rear; Rear of vehicle drops or sags noticeably; Spring missing or hanging from mounting point; No warning lights or prior symptoms in most cases
Codes mentioned: NHTSA Campaign 23V413000, Chrysler Recall 64A
Repairs/costs cited: Dealers replaced coil springs, isolator springs, upper and lower cradle bolts, and shock absorber nuts; however, multiple owners report springs detaching again after repair, sometimes within 13 days, suggesting improper installation or incomplete resolution
Recalls/TSBs owners mention: NHTSA Recall 23V413000 (Suspension) / Chrysler Recall 64A issued; however, not all affected 2023 Grand Cherokee L VINs are included in recall scope despite identical failures; some vehicles repaired under recall, others denied coverage
Engine motor mount noise and vibration
Persistent clunking, rattling, or knocking sound from front left suspension/motor mount area present from delivery. Dealership traced issue to engine motor mounts; disconnecting electrical connector eliminates noise. Replace of left front motor mount did not resolve issue. Dealership advised no current fix available and that Jeep needs to redesign motor mounts and control software.
When: From day one (new vehicle delivery); 10+ service attempts documented
Symptoms owners cite: Continuous clunking or rattling noise from front left side; Noise present whether parked or driving; Noise disappears only when motor mount electrical connector is disconnected
Repairs/costs cited: Left front motor mount replaced without resolving the noise; dealership advised no fix currently available
Recalls/TSBs owners mention: Known design issue per dealership assessment; Jeep aware but has not redesigned motor mounts or updated control software
Cracked suspension rail
Unknown suspension rail found cracked during dealer inspection. No clear cause identified and no repair performed.
When: Approximately 46,000 miles
Symptoms owners cite: Abnormal sound from vehicle while parked
Repairs/costs cited: Not repaired; cause not determined
Detached rear strut
Rear passenger-side strut found on the ground while vehicle was parked, causing abnormal noise.
When: Approximately 46,000 miles
Symptoms owners cite: Abnormal sound from vehicle while parked; Rear strut visible on ground
Repairs/costs cited: Not yet diagnosed or repaired at time of complaint
Accelerated inner tire wear from air suspension misalignment
Continental Cross Contact tires wearing excessively on inner tread lugs at 15,000 miles, traced to self-adjusting air ride suspension system. Wear pattern hidden from inspection since excessive wear occurs on innermost edge of tire. Alignment checked and confirmed correct, ruling out typical misalignment causes.
When: 15,000 miles
Symptoms owners cite: Excessive wear on inner tread lugs of all four tires; Inner tread worn to 0 depth; Wear not visible during normal inspection; Reduced traction and handling due to tire damage
Repairs/costs cited: Alignment verified correct; issue attributed to air suspension design defect
Rear left tension link bolt shearing
Bolt connecting top of left rear tension link sheared off, causing secondary damage to knuckle, axle, and tie rod.
Symptoms owners cite: Bolt failure on rear left suspension linkage
Repairs/costs cited: Damage to knuckle, axle, and tie rod resulted from bolt shearing

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.
