What stands out
No new NHTSA suspension complaint has been filed on this vehicle in over 10 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 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.
This Preliminary Information communication provides information to the technician about vibration complaints that are one of the most challenging complaints to accurately diagnose and repair. Technician will need to use Pico Oscilloscope Diagnostic Kit to effectively diagnosis vehicles. Technician should drive the vehicle will using the Pico Oscilloscope to record data. After the data is recorded it should be reviewed to determine the root cause of the concern. If a repair attempt made the concern better but not eliminated or had no affect at all, and are requesting assistance from General Motors Technical Assistance Center record another Pico file and save it to the computer.

The failure pattern owners describe
Owners report sudden rear ball joint failures across a 52,000 to 135,000 mile range. These break off without warning—usually with a loud bang—causing immediate loss of steering control and forcing vehicles off the road. One owner experienced this twice on the same vehicle: first at 115,000 miles (right rear joint), then at 135,000 miles (left rear joint), sliding into a ditch at highway speed. Another had the right rear joint fail at 52,000 miles with the wheel fracturing. In nearly every case, drivers describe taking significant control action to avoid hitting other vehicles or worse outcomes.
Front wheel bearings are failing prematurely. Owners report failures starting around 62,000 miles and recurring at 90,000 miles. One complainant who owned 2002 and 2004 Rendezvous models saw Buick cover bearing failures under warranty on those vehicles, then refused coverage on his 2006 at 62,100 miles. Another owner had the same bearing replaced three separate times, with failure recurring each time.
Tie rod problems and front-end alignment issues appear early in ownership or around 17,500–22,000 miles. Owners describe pulling to one side, front-end vibration, and loss of control at highway speeds. One owner's alignment reached the extreme correction limit at just 38,000 miles. Owners also report poor overall ride quality, stability, and control at highway speeds compared to other vehicles they've owned, which persists even after tire pressure correction and suspension repairs.
Failure modes owners describe
Rear Ball Joint Failure
Rear ball joints breaking off suddenly without warning, causing loss of steering control, wheel collapse, and dangerous loss of vehicle control on road.
When: 52,000 to 135,000 miles; can occur during normal driving or turning
Symptoms owners cite: Sudden loud bang or popping noise while driving; Abrupt loss of steering control; Vehicle pulling to one side; Wheel bent outward or collapsed; Rear tire blowing off rim after initial failure
Repairs/costs cited: Ball joint replacement; front tie rods also replaced in at least one case due to poor condition
Front Wheel Bearing Failure
Front wheel bearings failing prematurely, with some owners reporting multiple repeat failures even after repair attempts.
When: 62,100 miles; also reported around 90,000 miles; failures occurred under 50,000 miles on 2002 and 2004 model year Rendezvous vehicles owned by same complainant
Symptoms owners cite: Grinding sound from front end; Hard brake pedal when depressed
Repairs/costs cited: $358 to over $300 per bearing replacement; one owner reports three replacement attempts with recurrence each time
Recalls/TSBs owners mention: Buick refused warranty coverage on 2006 model after covering failures on 2002 and 2004 models under warranty
Tie Rod and Front End Alignment Issues
Tie rod ends failing or wearing excessively, combined with alignment problems that exceed normal adjustment range.
When: Early in ownership; 38,000 miles for alignment issue; front tie rods replaced between 17,500 and 22,000 miles on one vehicle
Symptoms owners cite: Vehicle pulling to the left at highway speeds; Front end vibrations; Poor control in snow despite new tires; Alignment at extreme of correction range
Repairs/costs cited: Tie rod ends and tires replaced, but problems persisted; alignment issue required potential drilling of new holes in front wheel section at cost over $200
Recalls/TSBs owners mention: Alignment work not covered under warranty
Sway Bar Damage
Front passenger-side suspension sway bar found bent, affecting ride quality and handling.
When: Discovered after purchase at 134,103 miles
Symptoms owners cite: Bent sway bar on driver's inspection
Poor Ride Quality and Handling
Overall suspension delivers poor ride quality, stability, and control compared to other vehicles, particularly at highway speeds and in adverse conditions.
When: Present from early ownership
Symptoms owners cite: Lack of smooth ride compared to 2003 model; Difficulty controlling vehicle at highway speeds; Poor traction control in snow even with new tires; Difficulty controlling at highway speeds after tire pressure correction
Repairs/costs cited: One case involved checking and correcting tire pressure from 28 PSI to 35 PSI, but problems persisted

I was driving on the freeway going around a bend at about 65 MPH when I heard a bang and thought it was the tire. It took all my effort to get it over to the side of the road. I have new tires on the vehicle. When I got out to look, the wheel was bent out and first thing I thought was tie rod. Tire is fine. When my husband and uncle came out they noticed the ball joint had broke off. Thank…
2006 buck rendezvous with 55,212 miles had front wheel bearings go bad. Cost was over $300 each to replace the front bearing assembly. Gm and buck refused to cover the cost. *tr
My last alignment was at the extreme of correction. I was told any further adjustments would require taking apart the front wheel section and drilling new holes to put in new adjusters. The car has 38k miles. I was told this was not a warranty item and it would cost over $200.00. *tr
Tl* the contact owns a 2006 Buick rendezvous. The contact was driving 20 MPH when the rear ball joint failed. The rear passenger wheel fractured and the contact lost control of the vehicle. The vehicle was taken to an authorized dealer where the ball joint was replaced. The contact called the manufacturer and was told that someone would return his call at a later date. The current and failure…

Common questions
How serious is the suspension problem on the 2006 Buick Rendezvous?
It's a meaningful issue. 13 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $900.
At what mileage does the suspension typically fail?
Across the 10 complaints that reported odometer mileage, most suspension failures cluster between 52,000 and 114,000 miles, with the median around 85,000. A quarter of owners report trouble before 52,000; a quarter make it past 114,000. 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 $900 for suspension 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.
Are there any recalls related to suspension?
No active recalls currently cover suspension issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
