Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries.

The failure pattern owners describe
Owners of 2010 Siennas report widespread power sliding door failures. The automatic door cable snaps, frays, or gets pulled into the motor, leaving doors stuck closed or partially open—a serious safety issue when kids need to exit quickly. Repair costs run $1,500 to $1,900 per door. Multiple owners note that Toyota covered this defect under warranty for 2004–2009 and 2011–2018 models but explicitly excluded 2010, despite identical failures. Some owners report warranty enhancement programs expired and Toyota refuses to reopen them.
Beyond cables, owners describe doors opening without command or closing on occupants—one incident involved a child's head trapped between the tire and door panel while a parent pulled the handle and the door kept sliding. Unintended door operation, missed sensor stops, and crushing injuries are reported.
One owner experienced a catastrophic electrical fire two to three weeks after battery replacement, with dashboard lights flickering, the infotainment screen cycling, then black smoke and flames erupting from under the hood. The battery appeared to explode, blowing out the windshield.
Other reported electrical gremlins include infotainment screens going black and unresponsive, cruise control shutting down unexpectedly, ABS pump failure codes ($3,600+ repairs), and key fob commands that unlock then immediately relock doors.

Failure modes owners describe
Power sliding door cable failure
Cables in the automatic door mechanism snap, fray, or are pulled into the door motor, preventing the door from opening or closing. Some doors will not latch properly; others lock up completely. Owners report this occurs on both driver and passenger rear sliding doors.
When: First reported around 3-5 years of ownership; failures reported across the vehicle's service life
Symptoms owners cite: Door will not open or close, even manually; Door partially opens then stops; Door can only open 6 inches; Loud noise from door motor before cable failure; Cable visibly snapped or frayed inside door structure; Cable sticking out below rear window; Door motor seized, preventing cable release
Repairs/costs cited: Repair estimates cited: $1,500 to $1,900 per door; includes cable assembly replacement; dealer diagnosis confirms cable failure
Recalls/TSBs owners mention: Toyota issued a customer warranty enhancement program for some model years (2004–2009, 2011–2018) but explicitly excluded 2010 model year despite identical defect; some owners report warranty expired and Toyota refuses to reopen it; no official recall issued for 2010 model year
Power sliding door unintended operation and sensor failure
Automatic sliding doors open or close unpredictably without driver input, or fail to stop when a person is in the door's path. Sensors fail to detect obstruction; in one instance, a child's head was crushed between the tire and door panel while the door continued sliding despite the parent pulling the door handle.
When: First occurrence reported ~8 months after purchase; intermittent throughout ownership
Symptoms owners cite: Door closes randomly with no warning pattern; Door opens when person is in path despite sensor; Crushing/impact injuries reported (shoulders, head, back); Parent unable to manually stop door motion; Door operates via remote with no command; Closing door hits occupant multiple times over vehicle's life
Repairs/costs cited: Owners report minor bruises and crushing injuries; one report of child's head trapped between wheel and door panel
Recalls/TSBs owners mention: Toyota aware of sliding door sensor issue dating back to 2004 model year per owner correspondence; customer was told extended electrical warranty did not cover sliding door sensor; no recall issued
Electrical fire—battery and charging system
Newly installed replacement battery and electrical system malfunction led to catastrophic vehicle fire. Shortly after battery replacement, dashboard lights flickered, infotainment screen cycled on and off, then fire erupted from driver's side engine compartment and hood. Battery appeared to explode; fire spread rapidly with risk to fuel tank. Fire department response required.
When: 2–3 weeks after battery replacement; 12/29/2022
Symptoms owners cite: Dashboard lights flickering; Navigation/audio screen turning off and restarting; Gray then black smoke pouring from hood; Sparks falling from driver's side engine compartment; Fire spurts from hood and below bumper on driver's side; Charring and melting observed at second and third row vents/lights; Loud explosion (battery rupture); Windshield blown out from explosion
Repairs/costs cited: New Duracell battery (3-year warranty) installed at Sam's Club North Little Rock, AR within 2–3 weeks before fire; vehicle had passed 199-point diagnostic at repair shop prior
Infotainment/navigation system failure
Navigation display screen goes black and displays 'No DVD. Please insert Map DVD' message. Subsequent buttons on navigation system and steering wheel controls become unresponsive. Reinserting map DVD does not resolve issue.
When: While driving on interstate
Symptoms owners cite: Navigation display turned black; DVD insertion request message displayed; All navigation system buttons non-responsive (radio, nav, Bluetooth, maintenance info); All steering wheel controls non-responsive
ABS actuator pump failure with diagnostic codes
Check Engine Light illuminated with multiple diagnostic fault codes. Dealer diagnosis indicates ABS actuator pump failure requiring replacement at high cost. Owner reports same codes and part failure documented in online forums and similar Toyota vehicles (Camry Hybrid received extended warranty coverage for identical issue).
When: Unspecified mileage
Symptoms owners cite: Check Engine Light illuminated
Codes mentioned: U0123, U0124, U0126
Repairs/costs cited: ABS actuator pump replacement estimate: $3,600+; yaw rate sensor also implicated in one code
Recalls/TSBs owners mention: Toyota extended warranty provided for Camry Hybrid with same part failure; no equivalent coverage offered for Sienna owner
Dynamic cruise control malfunction
Cruise control deactivates unexpectedly during operation with red warning light and audible chime. Additionally, bumper sensors detect objects that are not in front of the vehicle.
When: At 100,000 miles
Symptoms owners cite: Cruise control shuts off independently while operating; Red warning light and audible chime upon deactivation; Bumper sensor false positive detections
Repairs/costs cited: Dealer unable to diagnose or repair the failure
Key fob and door lock control intermittent failure
Key fob remote control malfunctions: unlock command immediately triggers relock; sliding door buttons activate intermittently; back hatch door opens but closes unexpectedly with no warning, trapping occupants.
When: Unspecified; owner reports at least 12 instances of hatch door closing unexpectedly
Symptoms owners cite: Key fob unlock followed by immediate relock; Sliding door buttons work intermittently; Hatch door opens then closes without command; Door sensor (eye) detects obstruction and re-opens, but lag creates entrapment risk; Owner struck in back and head multiple times by closing hatch; Dealership claims no prior reports of this problem
Repairs/costs cited: Owner received injury (hit in back and head); concerned about entrapment if sensor fails
Remote control system failure
Key fob remote control stopped functioning. Dealership reprogrammed the remote control for a service charge.
When: September 2011, approximately one year after purchase
Symptoms owners cite: Remote control did not function
Repairs/costs cited: Dealership charged for reprogramming service
Sliding door cable severed during door opening
Sliding door cable was cut off as the door opened, immediately rendering the door non-functional. Door cannot be opened after cable damage.
When: During normal door opening operation
Symptoms owners cite: Cable visible cut/severed during door motion; Door will not open after cable failure
Recalls/TSBs owners mention: Noted as Takata recall-related

The automatic sliding door cable broke, and we are now unable to open the door. Our children can only exit the car from the driver side door. We understand that Toyota is repairing certain model years with this safety issue, under an extended warranty. If the part is defective, why are some owners covered and others paying $2000 for repairs?
Airbag inflator needs replacing. Sliding door could open during car movement
Tl* the contact owns a 2010 Toyota sienna. When the cruise control was activated, it would deactivate independently.

My both side sliding doors are not functional. I could not use the key fob to open or close the doors. Wonder if it has any recall.
Our 2010 Toyota sienna recently had a CEL go on. No codes were found by local repair shop so took the car to Toyota dealer. Dealer gave us error code u0123, u0124, u0126 and said we would have to replace the ABS actuator pump which will cost $3600+. I searched online and many have/had the same problem. Also read that Toyota has already covered a extension warranty for the camry hybrid with…
Passenger power sliding door was closing when door cable along rear side window snapped. Door will no longer open or close, even in manual mode. This is a safety hazard not allowing passengers to egress in an emergency. A door malfunction should fail in a safe mode allowing the door to be opened and/or closed when a failure occurs. Toyota covered this repair up thru 2007 model year but refuse to…
