Should I buy a 2009 Toyota Prius with documented steering problems?

Depends on the price and the specific vehicle. Documented steering issues should be priced into the purchase — if the seller is asking full retail, negotiate down by the expected repair cost. A pre-purchase inspection from an independent shop tells you whether THIS specific vehicle has already shown the symptoms or not.

severe NHTSA 12V537000 November 14, 2012

Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 5, 2003, through March 30, 2009

Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash.

Fix: Toyota will notify owners, and dealers will inspect the extension shaft and replace it if it is one with insufficient hardness, free of charge. The recall began during December 2012. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.

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.

Service Bulletin T-TT-0578-19 Rev Oct 2020

TT: Some customers may encounter Bluetooth® connectivity concerns such as: ?Difficulty to pair the phone. ?Intermittent Bluetooth® failure to connect to the vehicle when first turning on the vehicle. ?Various Bluetooth® Audio functions are no longer functioning with customer?s phone such as ability to change the track using the steering wheel controls. These concerns can be caused by changes made on the customer?s phone. Make sure to inquire with the customer if the connectivity concerns occurred after receiving an operating system update on their phone, or if they have restored their phone data/settings recently.

The failure pattern owners describe

The 2009 Prius steering system shows multiple failure modes. Owners report complete loss of steering control—where the wheel either locks solid or spins freely without turning the wheels—sometimes while driving at highway speeds or during turns. One owner hit 108,000 miles before the electronic power steering ECU failed; another at just 3,000 miles. At least one steering failure occurred after hitting a curb, suggesting impact vulnerability in the intermediate shaft and cable assembly.

Highway driving reveals steering wander and side-to-side instability above 60 mph, especially in crosswinds or wet conditions. Owners describe continuously correcting the wheel to hold a straight line. The problem worsens on curves and overpasses.

One owner experienced simultaneous brake and steering loss after accelerating from a stop—warning lights activated, brakes became unresponsive, and steering failed. The condition temporarily resolved after power cycling but the owner was charged for repair.

A concerning pattern: Toyota issued recalls for the intermediate shaft and spiral cable assembly in 2004–2006 models for this exact problem. The same failures are being reported on 2009 vehicles. Dealership technicians have been unable to reproduce intermittent failures or offered no solution, telling owners the behavior is "working as designed."

Failure modes owners describe

Electronic Power Steering Loss / Complete Steering Lockup

Power steering system fails, leaving the driver unable to steer the vehicle. In some cases the steering wheel locks completely; in others it turns freely but does not turn the wheels (loss of mechanical connection).

When: While driving at various speeds; one reported at 108,331 miles; one at 3,000 miles; some intermittent

Symptoms owners cite: Steering wheel becomes difficult or impossible to maneuver; Steering wheel turns freely but wheels do not respond; Steering wheel locks completely; Warning lights illuminate and beeping occurs; Engine dies when steering freezes; Loss of steering on curves or during turns

Repairs/costs cited: Toyota dealer replaced intermediate shaft and spiral cable sub-assembly in one case; electronic power steering ECU replaced in another case

Recalls/TSBs owners mention: Toyota recalled this item (intermediate shaft and spiral cable) in 2004, 2005, and 2006; problem reportedly persists in 2009 model. Dealers unable to diagnose intermittent failures in multiple instances. Toyota customer service told one owner 'the car is working as designed.'

Steering Wander / Instability at Highway Speeds

Vehicle steering is unstable, causing the car to shift side-to-side on the road. Driver must continuously correct to keep vehicle traveling straight. Worse in cross-wind conditions.

When: While operating at speeds over 60 mph

Symptoms owners cite: Car shifts from side to side; Driver must continuously move steering wheel to keep car straight; Instability exacerbated in cross-wind conditions; Problem persists in wet conditions; Extreme understeer reported, especially in wet conditions and on curves

Recalls/TSBs owners mention: Local dealer and Toyota customer service told owner 'the car is working as designed.' Owner found many other Prius owners (various model years) reporting the same problem on internet forums.

Steering Control Loss with Brake / Throttle Issues

Loss of steering control occurs in conjunction with brake and throttle system malfunctions. Warning lights and beeping activate. Driver unable to brake effectively while steering is compromised.

When: After pulling away from red light; around 25 mph

Symptoms owners cite: All warning lights turn on and vehicle beeps; Unable to brake effectively; Unable to steer; Vehicle does not respond to driver input; Problem resolves temporarily after turning vehicle off and on

Repairs/costs cited: Dealer attributed to accelerator and brake system issue; owner charged for repair

Recalls/TSBs owners mention: Toyota dealership informed owner issue was with accelerator and brake system; owner disputes manufacturer responsibility

Steering Failure Following Minor Impact

After hitting a curb or minor obstacle, the steering system fails. The intermediate shaft or steering control mechanism loses integrity.

When: After hitting a curb; after hitting a tree on county road

Symptoms owners cite: Loss of all steering control; Steering wheel turns freely but wheels do not respond; Steering wheel breaks (structural damage); No responsiveness to steering input

Repairs/costs cited: Intermediate shaft and spiral cable sub-assembly replaced by Toyota dealer

Recalls/TSBs owners mention: Toyota had recalls for this exact component in 2004, 2005, and 2006 models; appears to be unresolved in 2009
