This service bulletin provides information on some vehicles that may rock or move slightly forward or rearward while in Park at start up after cold soak. This condition may be accompanied by a clunk noise. This is a slight movement that is more often seen visually, rather than felt, when viewed from the outside and using the auto-start feature, if equipped.

What stands out
Powertrain accounts for 21% of all owner complaints filed against this vehicle, across 8 categories tracked.
No new NHTSA powertrain complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain 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.
GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

The failure pattern owners describe
The 2007 Cadillac SRX shows a pattern of severe powertrain failures across 11 complaints. Most serious is sudden, unannounced power loss—the engine keeps running but the vehicle refuses to move, as if dropped into neutral, occurring as early as 25,000 miles and recurring every few days or weeks. One owner experienced vehicle lockdown at speed, lost control, and collided with another car. A restart temporarily fixes the condition, but dealers cannot diagnose or repair it.
Rear differential problems dominate the cluster. Multiple owners report pinion seal leakage starting around 60,000 miles, causing complete oil depletion and severe grinding noise. One owner's pinion seals failed again after recall replacement. Differential gasket ruptures also leak profusely, creating loud banging audible enough to alarm passengers. Wheel assembly fasteners have loosened, causing a wheel to separate during driving. One owner's transfer case failed at 54,000 miles, causing jerking at all speeds; an independent shop charged $2,700 and noted the problem is common for this model.
Recall 07V589000 (powertrain) addresses pinion seals, but applies only to specific VINs. Owners with identical failures outside that range face dealer refusals and full-pocket repair costs. One owner spent 13 months in the shop waiting for a complete differential replacement after an initial attempted seal repair made the leak worse.

Failure modes owners describe
Sudden power loss / transmission lockup
Vehicle loses all power output without warning lights or engine shutdown, decelerating from highway speed to a stop in seconds. Engine continues running but car behaves as if in neutral. Condition resolves temporarily after key-off/key-on restart, then recurs after days or weeks. One reported incident involved vehicle locking down entirely while driving, causing loss of control and collision.
When: Starting at 25,000 miles; occurred 4–5 times over vehicle ownership
Symptoms owners cite: Sudden loss of power without warning lights; Rapid deceleration despite throttle input; Engine running but no drive; Condition clears after restart; Vehicle locks down (in one case), causing crash
Repairs/costs cited: Dealer unable to reproduce; condition undiagnosed and unrepaired
Recalls/TSBs owners mention: Recall 07V589000 (powertrain); dealer stated no ability to diagnose without reproduction
Rear differential pinion seal failure and oil loss
Rear axle pinion seals leak gear oil, leading to complete oil depletion and major internal damage. Owners report fluid pooling under vehicle, loud grinding noise during acceleration or shifting, and jerking sensation. Some seals were initially replaced under recall but failed again. Dealers initially denied warranty coverage for vehicles outside specified recall VIN ranges despite identical symptoms.
When: 57,900 miles; 65,000–70,000 miles; 112,200 miles; 150,000 miles
Symptoms owners cite: Gear oil leaking under vehicle; Loud grinding noise in rear; Jerking or banging when shifting into first gear; Check engine light illumination; Steering wheel shake
Repairs/costs cited: Pinion seals replaced under recall; complete rear differential axle replacement required in some cases ($2,700+ noted in related repairs); one owner waited 13 months in shop for full differential replacement
Recalls/TSBs owners mention: Recall 07V589000 (powertrain); recall limited to specific VIN range, leaving many owners with identical failures outside coverage
Rear wheel assembly fastener failure
Wheel attachment fasteners (nuts) loosen or back off the axle shaft, causing wheel to separate during driving. Owner reported that wheel literally fell off the axle while driving. Previous service on traction control system may have been involved, though dealer initially denied connection.
When: Within one month of traction control service at dealer (June–July 2007)
Symptoms owners cite: Wheel nut comes loose on rear axle; Wheel separates from vehicle during driving; Grinding noise when turning front wheels
Repairs/costs cited: Wheel nut replaced; service manager acknowledged possible connection to prior traction control work
Rear differential gasket rupture
Differential housing gaskets rupture, causing gear oil to leak. Often accompanied by loud banging or knocking noise. Condition occurs across wide mileage range. Owners report dealership denials of warranty coverage for vehicles not in specific recall VIN batch despite identical failure mode to recalled components.
When: 65,000–70,000 miles; 112,200 miles
Symptoms owners cite: Fluid leak under vehicle; Loud banging or knocking noise; Noise loud enough to alarm passengers
Repairs/costs cited: Gasket replacement attempted; one owner experienced worse leak post-service, requiring full differential replacement
Recalls/TSBs owners mention: Recall 07V589000; dealers deny coverage for out-of-range VINs despite matching failure
Transfer case failure
Transfer case internal failure causing jerking and loss of vehicle control during driving across all speeds. Failure occurred at relatively low mileage (54,000 miles).
When: 54,000 miles
Symptoms owners cite: Vehicle jerks back and forth at all speeds; Loss of control during driving
Repairs/costs cited: $2,700 repair cost; independent mechanic noted this is a common problem for this model year
Secondary engine check light issues and sensor failures
Check engine warning light illuminates and remains on. In one case, owners reported steering wheel shake and clicking from rear. Another case involved fuel injector and mass air flow sensor failure. One owner experienced check light refusal to clear after differential repair, requiring replacement of camshaft sensors and timing chains.
When: 30,000 miles (post-repair check light); 110,000 miles; 150,000 miles
Symptoms owners cite: Check engine light illumination; Steering wheel shake; Clicking sound from rear; Check light failure to clear after service
Repairs/costs cited: Fuel injector, mass air sensor, camshaft sensors, and timing chains replacement; extended shop time (13 months in one case) for resolution

Tl* the contact owns a 2007 Cadillac srx. While driving approximately 60 MPH, there was an abnormal noise coming from the rear of the vehicle. The vehicle was not diagnosed or repaired. The VIN was not included in NHTSA campaign number: 07v589000 (power train) the manufacturer was not notified of the failure. The VIN was unknown. The failure mileage was 60,000.
Without any notice or lights or anything, my 2007 Cadillac srx will loose power and decelerate from 60 to 0 in just a few seconds. I can have the gas pedal to the floor and the car does not move, even though the motor is still running. It is as if the car is in neutral. Once you turn the car off and on again, it will run fine for a few days or a week or so before happening again. This has…
