What stands out
Owners have filed 68 powertrain 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.
Among the 20 model years of Toyota Tacoma in our records for powertrain problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2009 Tacoma automatic transmission has a well-documented pattern of hesitation and slipping during low-speed driving, especially after turns—owners report this causes dangerous surging and leaves them vulnerable in traffic. Dealers universally told owners this was "normal," but independent research and NHTSA complaints show it affected hundreds of 09 Tacomas; Toyota never issued a recall or permanent software fix.
The 2009 Tacoma automatic transmission (5-speed ECT-i) exhibits a consistent failure pattern across 68 complaints: when slowing to 10–20 mph for turns or traffic, pressing the accelerator produces 2–3 seconds of engine revving with zero power delivery, followed by an abrupt lurch forward once the transmission finally engages. Owners describe this as terrifying in intersections with oncoming traffic.
Related failures include cruise control overspeeding past set limits on hills, violent lurching when shifting from neutral to drive, spontaneous engine racing at stops, and hard downshifts into first gear that jolt the vehicle mid-turn. A few complaints cite transmission line corrosion, driveshaft vibration, and clutch slipping on manual models.
Dealers consistently told owners the behavior was "normal for the model" or blamed a computer that needed to "learn driving habits"—sometimes claiming 5,000 miles were needed before normal operation resumed. Toyota confirmed awareness in some cases but never issued a recall or TSB with a permanent fix. One dealer mentioned similar issues on Camry models had been resolved with software reprogramming, but stated no fix was available for the 09 Tacoma. Owners documented dozens of identical complaints on forums and EDMUNDS before filing with NHTSA, yet manufacturer response remained unchanged.

Failure modes owners describe
Transmission hesitation/slipping on low-speed acceleration
After slowing to 10–20 mph (turning, yielding, or decelerating), pressing the accelerator produces engine revving with 2–3 second delay before transmission engages. Vehicle lurches forward when gear finally engages, or transmission stays in neutral-like state. Occurs consistently, often multiple times per drive.
When: Present from early ownership (150–3700 miles reported); low-speed driving situations
Symptoms owners cite: Engine revs 1500–2000+ rpm with no vehicle response; 2–3 second delay between pedal press and transmission engagement; Sudden lurching/surging forward when transmission finally engages; Transmission feels like it's searching for the correct gear; Occurs after slowing for turns, traffic, or deceleration
Repairs/costs cited: Dealers report no fix available; some performed 'shift logic resets' with no lasting result; one case involved computer module replacement that failed to resolve issue; Toyota stated computer needs to 'learn driving habits'
Recalls/TSBs owners mention: Dealers and Toyota told owners behavior is 'normal for the model,' 'new technology,' or 'computer learning.' Toyota stated no TSB applies; no recall issued. Mentioned computer 'patch' or software fix in development but no timeline given.
Cruise control overspeed/unintended acceleration
Cruise control engaged, vehicle accelerates past preset speed on resume or during downshift on hills, reaching 80–95 mph. Problem stops when cruise control is disengaged. Patterns include downshift and acceleration maintaining preset speed but continuing past it.
When: During highway cruise control use, on hills or after resume; early ownership
Symptoms owners cite: Vehicle accelerates 15+ mph past preset cruise speed; Continues accelerating past safe speed despite foot off pedal; Occurs during transmission downshift for hill climbing; Only halts when cruise control manually disabled
Repairs/costs cited: Dealer told owner cruise control unit replacement needed but would not perform without reproducible problem; documented but not repaired
Recalls/TSBs owners mention: Dealer refused repair due to inability to replicate; case documented
Engine racing/unintended rpm increase at stops
While stopped (red light, parked, brake applied), engine RPM increases spontaneously to 3000–5000 rpm. Vehicle may lurch forward or show signs of wanting to move despite brake. Shifting to neutral stops the revving.
When: At complete stops, early to mid-ownership
Symptoms owners cite: Engine races to 3000–5000 rpm while stopped and braking; Vehicle lurches or moves forward when RPM spikes; Revving stops when shifted to neutral; Occurs intermittently, not every stop
Repairs/costs cited: Dealer performed 'system health check' with normal results; could not replicate; one case also involved gas pedal stuck situation with no resolution
Recalls/TSBs owners mention: No fix provided; floor mat was verified not to be cause
Transmission lag/no-response on neutral-to-drive shift
When shifting from Neutral or Park to Drive, transmission spins or hesitates for 2–3 seconds before engaging, or vehicle lurches violently when gear finally engages. Sometimes causes wheelspin.
When: At traffic lights and stops; from early ownership
Symptoms owners cite: Transmission spins without engagement for 2–3 seconds; Sudden violent lurch when transmission finally engages; Can cause wheelspin or unexpected surge; Occurs almost every time vehicle is put in drive from stop
Recalls/TSBs owners mention: Dealers said behavior is 'normal' or 'characteristic of that year transmission'; no repair offered
Erratic downshifting and engine lugging during turns
Automatic transmission downshifts abruptly to first gear when slowing for turns, causing engine to lug and vehicle to lose smooth deceleration. Hard downshift followed by abrupt re-engagement when accelerating out of turn.
When: When turning at speeds 10–35 mph; occurs almost every drive
Symptoms owners cite: Transmission drops into first gear unexpectedly during turn entry; Engine races/lugs during turn deceleration; Sudden re-engagement and lurch when exiting turn; Vehicle loses smooth braking feel; Downshift noticeable and jarring for an automatic
Repairs/costs cited: Dealer 'reset learn code' in one case without success
Recalls/TSBs owners mention: Dealers stated 'normal for the model' or 'normal transmission operation.' One dealer mentioned similar past issues on other Toyota models were fixed with software update, but no fix available for 09 Tacoma.
Shuddering/vibration at cruising speeds
Vehicle shakes or vibrates for 2–3 seconds when reaching 35–40 mph during cruise, consistent and reproducible. One owner diagnosed with torque converter lockup problem.
When: At 35–40 mph during acceleration to cruise speed
Symptoms owners cite: Vehicle shakes or shudders for 2–3 seconds; Occurs consistently when entering cruise speed range; Reproducible condition
Repairs/costs cited: Dealer diagnosed torque converter lockup problem and recommended full transmission replacement
Recalls/TSBs owners mention: TSB does not pertain to out-of-warranty vehicles; no repair offered based on warranty status
Transmission line corrosion and leakage
Transmission line rusted through, causing fluid leak and transmission failure. Vehicle stalled when pulling into driveway.
When: At 65,000 miles
Symptoms owners cite: Transmission fluid leaking beneath vehicle; Transmission suddenly disengages and vehicle stalls; Forward gears become inoperable
Repairs/costs cited: Transmission line replaced by independent mechanic; transmission still required replacement; repair cost not specified in complaint
Recalls/TSBs owners mention: Manufacturer stated VIN not under recall for this failure; corrosion initially cited as reason to deny warranty coverage despite warranty claim
Clutch slipping (manual transmission vehicles)
Manual transmission clutch slips, causing inability to maintain power during acceleration. Slipping began at 5,000 miles and worsened significantly by 15,000 miles.
When: 5,000–15,000 miles
Symptoms owners cite: Clutch slips during acceleration from standstill; Vehicle unable to maintain power output; Slipping progressively worse over short mileage
Repairs/costs cited: Dealer refused to recognize as warranty issue; requested $480–$1,000 authorization before inspection
Recalls/TSBs owners mention: Dealer classified as wear issue rather than defect; no warranty coverage
Driveshaft vibration and universal joint wear
Driveshaft vibration beginning around 40 mph and increasing through 60 mph. Toyota issued warranty enhancement (ZH2) covering universal joint replacement, but vibration persisted even after parts and center support bearing replacement at owner cost.
When: At 40+ mph highway speeds
Symptoms owners cite: Vibration at 40 mph increasing through 60 mph; Grinding noise from driveline on deceleration; Vibration continues after warranty repair
Repairs/costs cited: Toyota ZH2 warranty enhancement covered parts replacement; owner paid out-of-pocket for center support bearing; vibration unresolved
Recalls/TSBs owners mention: Issued warranty enhancement (ZH2) rather than full recall; denies need for further remediation
Transmission shift refusal/stuck in gear
Transmission refuses to shift gears until vehicle is turned off and restarted. Occurs intermittently in early ownership.
When: Early ownership (2,100 miles reported)
Symptoms owners cite: Transmission will not shift for period of time; Requires vehicle shutdown and restart to regain shifting; Intermittent occurrence
Repairs/costs cited: Dealer investigation inconclusive
Recalls/TSBs owners mention: No resolution provided
Brake and transmission interaction issues
Brake pedal goes to floorboard momentarily during low-speed driving; separate incident of vehicle shifting from regular gear to 4WD on its own at highway speed. Service engine light and traction control indicator illuminated.
When: At 79,899 miles; during regular and highway driving
Symptoms owners cite: Brake pedal sinks to floor without stopping vehicle; Unwanted shift to 4WD at highway speed; Service engine and traction control lights illuminate
Repairs/costs cited: Transmission fluid added; metal piece removed from fuel tank cover by dealer
Recalls/TSBs owners mention: Manufacturer told owner 'unintended acceleration template' was the problem; owner did not believe vehicle was properly repaired
Idle creep and driveline wrap
Vehicle nudges or moves slightly while stopped with brake applied and engine running. Phenomenon attributed by online sources to driveline wrap (drivetrain loading under engine torque at idle). Gets worse over time or recurs after tire changes.
When: At every stop; present since early ownership
Symptoms owners cite: Vehicle nudges or creeps forward while at stop with brake engaged; Additional nudge when brake is released; Problem worsens over time; Recurs after tire replacement
Repairs/costs cited: No repair provided by dealer; one case noted new tires temporarily reduced issue
Recalls/TSBs owners mention: Dealer characterized as 'characteristic of that year transmission'; no fix offered despite owner reporting it did not occur at purchase
