Owners report a suspension system full of trouble. The most critical issue is rear coil spring detachment—springs are popping off completely while driving at normal speeds (20–65 mph) and while parked, causing the vehicle to drop on one side and lose control. One owner's springs failed twice, on opposite sides, eight weeks apart, with the second failure never fixed. These failures are occurring even after dealership repairs under recall 23V413000. Owners also describe rear axle and tension link components bending and lodging into steering knuckles, fracturing the knuckles with bolts breaking inside.
Beyond springs, owners report extreme vibration and instability at highway speeds, loss of steering control, and difficulty holding lane position. Powertrain mounts are wobbling and driveshafts making alarming noise. The front suspension—particularly driver's side—is cracking and clunking with every turn, maneuver, and bump.
One owner experienced total engine and power steering shutdown at 55 mph on a highway after intermittent warnings, leaving them without steering control. That vehicle sat unrepaired for over two months.
Persistent metallic rattling sounds have sent some vehicles to dealerships 10+ times in a year with no resolution. Sway bars, links, and shocks are being replaced repeatedly without fixing the underlying problem.
Finally, owners report a parts shortage prevented recall repairs for 30+ days, leaving them driving vehicles they considered unsafe while waiting for components with no clear timeline from manufacturers.
Failure modes owners describe
Rear Coil Spring Detachment
Rear coil springs detach from the vehicle while parked or driving at various speeds (20–65 mph). Springs fall completely free, causing the vehicle to drop on that side and creating dangerous instability. Some failures occur even after dealership repairs under recall 23V413000, indicating the repair may not resolve the underlying issue.
When: As early as 5 months and 9,000 miles; recurrences at 40,000+ miles; also occurs while parked
Symptoms owners cite: Loud bang or popping sound from rear; Vehicle suddenly drops or tilts to one side; Rear end sitting uneven (one side lower than the other); Vehicle pulling to left or right when spring detaches while driving; No warning lights on dashboard in most cases
Repairs/costs cited: Dealerships replace rear coil springs, tension links, CV axles, and steering knuckles. Repairs completed under NHTSA Campaign 23V413000 and FCA Campaign 64A (both suspensions/coil springs). Some owners report repair completed but springs still had original part numbers and same failure recurred within weeks or months.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V413000 (Suspension). FCA Campaign 64A. Manufacturers declined buyback requests in some cases. Parts for recall repair were backordered for 30+ days, delaying fixes despite owner safety concerns.
Persistent Rattling Noise from Suspension
Persistent metallic rattling or cracking sounds from the suspension system that dealerships have been unable to diagnose or repair after multiple visits. Noises occur during normal driving, turning, reversing, and over bumps, suggesting a structural or fastener issue that repair attempts have not resolved.
When: From early ownership (some from May 2023 purchase); persists after multiple repair attempts over 9+ months
Symptoms owners cite: Metallic rattling or cracking sound coming from underneath vehicle or front driver's side; Sound audible during reversing, three-point turns, straight driving, and left/right turns; Vibration felt in feet and steering wheel; No warning lights illuminated
Repairs/costs cited: Unknown parts have been replaced at dealerships on 10+ occasions for one owner in one year, with no permanent fix achieved. Owners report 3–4 week service stays without resolution.
Recalls/TSBs owners mention: Owner contacted Jeep in November 2023 with certified letter and Chrysler Board of Arbitration multiple times in December 2023; no callback received. Lemon law case opened but unresolved after 9 months.
Rear Axle and Tension Link Bending/Fracturing
Rear axle and tension link components bend and lodge into the steering knuckle, fracturing the knuckle and its bolts. This causes vehicle to pull sharply to one side and drop. One owner experienced this failure on both sides of the vehicle (8 weeks apart), with the second failure never repaired.
When: At 62,000 miles for first occurrence; second occurrence at unknown mileage 8 weeks later
Symptoms owners cite: Vehicle unexpectedly lowers at speed (20–40 mph); Vehicle pulls sharply to one side (right, then left); Abnormal sound from rear of vehicle; No visible failure obvious to driver upon inspection
Repairs/costs cited: Dealer diagnosed bent rear axle, bent tension link lodged in knuckle, fractured steering knuckle with fractured bolt inside. Required replacement of tension link, CV axle, and steering knuckle. Second failure remained unrepaired at time of complaint.
Recalls/TSBs owners mention: Manufacturer was notified of failure.
Quadra-Lift Air Suspension Failure
Air suspension system failed multiple times while driving and during repair work, with less than 1,000 miles on the vehicle. No clear diagnostic follow-up documented by owners.
When: Fewer than 1,000 miles on vehicle
Symptoms owners cite: System failure while being driven; System failure during repair work; Warning notice light after system failed (no prior warning light); Vehicle spent more time in shop than on road
Repairs/costs cited: Inspected and worked on by Covert Chrysler Dodge Jeep and Caliber Collision in Austin, TX. USAA Insurance inspected photos. Detailed repair outcomes not specified by owner.
Complete Vehicle Shutdown and Loss of Power Steering
Engine and power steering completely shut off while driving on highway at 55–60 mph, leaving driver without steering control. Occurred after intermittent 'Service Hybrid System' warning codes. A digital crash code appeared but no repair timeline was provided. Vehicle remained unrepaired for 60+ days.
When: After initial Service Hybrid System warnings in February 2025; actual failures in June 2025 at 26,000 miles
Symptoms owners cite: Intermittent 'Service Hybrid System' code flashing for 3–5 seconds, appearing 4–5 times before failure; Complete engine shutdown with no power to engine or power steering; Aggressive jerking when shutdown occurs; System restarts but only runs in 'e-save' mode
Codes mentioned: Service Hybrid System, Digital crash code
Repairs/costs cited: Vehicle has been at dealership since failure; no estimated time for repair. Warranty applies but repair not progressing.
Recalls/TSBs owners mention: Stellantis denied buyback request despite 26,000 miles and active warranty coverage.
Extreme Vibration and Suspension Instability
Excessive vibration throughout the vehicle at highway speeds, loss of steering stability, difficulty maintaining lane position, and exaggerated bounce on bumpy roads. Owners suspect this is not an alignment issue but a structural suspension defect.
When: Reported on CPO vehicle; another owner with similar symptoms in 2022 model year
Symptoms owners cite: Extreme vibration at all speeds, worsening daily; Loss of steering stability at highway speeds; Difficulty maintaining lane position; Hard, stiff bounce-back on bumpy roads; Unstable, bouncy driving condition
Repairs/costs cited: Not yet repaired; owner concerned this is not an alignment issue.
Recalls/TSBs owners mention: Stellantis Corporate failed to provide safety compliance review despite being a certified pre-owned vehicle sale.
Front Suspension Cracking/Clunking and Control Arm Defects
Front driver's side suspension produces cracking sounds with each movement and vibration felt through steering wheel and pedals, suggesting control arm, ball joint, or upper/lower link failure. Similar complaints reported on 2022 model; symptom mimics recalled rear spring issue but on front.
When: Noted on 2023 model; also reported on 2022 Grand Cherokee by other owner
Symptoms owners cite: Cracking sound from front driver's side during reversing, turning, and straight driving; Vibration and instability felt through steering wheel and feet; Vibration and noise when going through bumps; Vehicle will shift/skip and jump off pavement
Repairs/costs cited: Dealership uncertain if covered by recall or separate defect. Owner driving no faster than 40–45 mph out of safety concerns and has not completed repair.
Recalls/TSBs owners mention: Recall coverage unclear; owner report indicates dealership unable to confirm if related to 23V413000.
Powertrain Mount Weakness and Driveshaft Noise
Powertrain wobbles and vibrates severely at highway speed due to weak or worn-out mounts. Driveshaft produces scary noise when accelerating. These issues could lead to shaft failure and loss of driver control.
When: At highway speeds (70 mph noted)
Symptoms owners cite: Powertrain wobbles and vibrates at 70 mph; Driveshaft makes scary noise when accelerating; Instability at speed
Repairs/costs cited: Owner reported issue during third service visit; inspection recommended but not completed at time of complaint.
Suspension Component Looseness (Isolators, Sway Bars, Links)
Coil spring isolators come loose and unattached, allowing springs to fall out. Sway bars and suspension links have required multiple replacements without permanent resolution. Rear shocks also replaced.
When: Throughout ownership; multiple repeat repairs documented
Symptoms owners cite: Upper coil spring isolator comes unattached; Coil spring falls out as a result; Clunking sounds from suspension; Poor suspension ride quality
Repairs/costs cited: Dealerships have replaced sway bars, sway bar links, rear shocks multiple times on some vehicles without achieving permanent fix. Isolators and springs require repeated replacement.
Parts Unavailability Delaying Recall Repairs
Multiple owners received recall notifications (23V413000) but could not schedule repairs because replacement coil spring parts were backordered for 30+ days. Manufacturers exceeded reasonable repair timelines while owners drove unsafe vehicles.
When: Recall notification issued; parts unavailable for extended periods following notification
Symptoms owners cite: Recall parts on backorder; Repairs delayed 30+ days; No loaner vehicles provided; Owners unable to drive vehicles due to safety concerns
Repairs/costs cited: Dealers confirmed parts unavailable. Manufacturers stated parts were available, but discrepancies existed between dealer and manufacturer statements.
Recalls/TSBs owners mention: NHTSA Campaign 23V413000 parts backordered. Manufacturers provided no loaner vehicles or interim solutions while parts were unavailable.
