What stands out
Steering accounts for 31% of every owner complaint on file for this vehicle — the dominant problem area across 8 categories tracked.
Owners have filed 32 steering complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering steering 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.
This Preliminary Information communication provides information to the technician the steps needed to diagnose and repair the vehicles that may have unwanted or phantom phone calls. Technician will need to determine what type of call the customer is having that is unwanted. The vehicle may receive an incoming call just like any other phone. Typically the customer will hear the phone ringing in the vehicle. This scenario also includes incoming Bluetooth calls. One type of unwanted call can be made if the key pad is faulty the OnStar system will try to make a blue button call for shorted voltage in the circuits.

The failure pattern owners describe
The dominant complaint across these narratives is wet-weather power steering lockup. Owners report the steering wheel freezes, becomes immovable, or requires extreme force to turn when the vehicle contacts standing water, puddles, or wet road surfaces. Lockup lasts 5–60 seconds, then restores to normal or resumes after restarting the engine. This failure occurs at any speed and has happened to owners multiple times over their ownership period, sometimes recurring dozens of times. One owner reported 7–8 failures in a single month; another had the problem recur three times in two days.
Dealers have acknowledged multiple customers report this issue but universally state no recall exists and no permanent remedy is available. One dealer identified water reaching the serpentine belt as the culprit; attempted fixes include belt replacement, pulley replacement, and power steering pump replacement (one owner's pump was replaced three times). Splash shields have been inspected and found intact, ruling out obvious water intrusion paths.
A secondary concern is ball joint failure: one owner's driver-side ball joint broke at low mileage, causing the wheel to separate and the vehicle to drop to the ground. Additionally, owners report a steering wheel lockup event tied to ignition failure, and one complaint describes an unresolved steering loss that caused a crash into a fire hydrant.
Failure modes owners describe
Power steering lockup in wet conditions
Power steering seizes, locks up, or becomes extremely difficult to operate when the vehicle contacts standing water, puddles, or wet road surfaces during rain. The steering wheel becomes nearly immovable or immobilized for 5–60 seconds, then restores to normal operation either spontaneously or after restarting the engine.
When: 17,000–170,000 miles; occurs during rainy weather or within hours/days of rain exposure
Symptoms owners cite: Steering wheel locks or becomes immovable when turning through water or puddles; Extreme force required to turn steering wheel; Squealing or screeching noise from serpentine belt before lockup; Power steering disengages temporarily; re-engages after seconds or engine restart; Failure occurs at any speed, low or high; Steering is extremely difficult to control during wet-weather failures
Repairs/costs cited: Serpentine belt has been wet from water splash and loses grip on power steering pump; dealer replaced serpentine belt, pulleys, and power steering pump (pump replaced multiple times on some vehicles) without resolving the issue. One dealer advised customer water was reaching the belt; another replaced a right-side pulley in March 2010 with no improvement. Splash shield was inspected and found intact on at least one vehicle.
Recalls/TSBs owners mention: Dealers acknowledged other customers reported the same failure (per complaints #1, #3, #6, #10). No recalls issued. One dealer informed customer there was no current remedy and advised him to file an NHTSA complaint. Cadillac advised one customer there was no information or recalls for this problem despite it being reported on 2003–2005 models for years.
Ball joint failure
Driver-side front ball joint broke without significant mileage accumulation, causing the wheel to come off and the vehicle to drop to the ground. The complainant considers this an engineering defect related to inferior metal strength and quality in the OEM ball joint.
When: Low mileage; exact mileage not stated but within reasonable service life expectation
Symptoms owners cite: Wheel came off vehicle; Vehicle dropped to ground after backing out of driveway and beginning normal acceleration
Repairs/costs cited: Driver-side ball joint broke; wheel removal and replacement required.
Steering wheel difficulty and squeaking (ignition-related)
Steering wheel becomes difficult to maneuver and produces squeaking noise when turned. This occurred in conjunction with an ignition failure (key would not insert) and air bag indicator illumination. A locksmith rebuilt the ignition.
When: 111,808 miles
Symptoms owners cite: Steering wheel difficult to maneuver; Squeaking noise when turning steering wheel; Air bag indicator illuminated; Key unable to insert into ignition
Repairs/costs cited: Locksmith rebuilt the ignition; vehicle was not fully repaired by dealer.
Excessive vibration at highway speeds
Vehicle experienced excessive vibration while driving at 60–70 mph. The cause was not definitively identified despite replacement of the front passenger-side rim and all four tires.
When: 29,000 miles
Symptoms owners cite: Excessive vibration at 60–70 mph
Repairs/costs cited: Front passenger-side rim and all four tires were replaced; vibration persisted.
Ignition cutting out while driving
Engine and power steering cut off at random times while in motion when the vehicle hits bumps, railroad tracks, potholes, or even when the column cover is bumped. The ignition appears to rotate out of the ON position unexpectedly. Vehicle was modified for a key recall, but the problem persisted.
When: Timing not specified
Symptoms owners cite: Engine cuts off at random times while in motion; Power steering cuts off when vehicle hits a bump, railroad track, or pothole; Engine and power steering cut off when column cover is bumped; Ignition rotates out of ON position randomly
Repairs/costs cited: Key modification was performed as part of a recall but did not resolve the ignition rotation issue.
Steering control loss and vehicle swerve/crash
Vehicle swerved without driver input and crashed into a fire hydrant during normal driving. The steering control was lost, suggesting a spontaneous failure of the steering system.
When: 47,000 miles
Symptoms owners cite: Vehicle swerved and crashed into fire hydrant; Loss of steering control

A quarter of owners report trouble before 50,000; a quarter make it past 97,500. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $700 for steering repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
