What stands out
Owners have filed 143 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 21 model years of Toyota Camry in our records for powertrain problems, this one ranks #3 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain 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.
Warranty Policy Bulletin: Toyota has received some reports where vehicles may exhibit a brief intermittent shudder during torque converter flex lock up. This shudder may be observed while driving under light throttle conditions between approximately 25 ? 50 mph.
full bulletin at NHTSA ↗Dealer Package: Date 02/15/18 ZE5 previously stated that LSC E03 had to be completed prior to performing ZE5. LSC E03 is now expired and is no longer a prerequisite for ZE5. Language stating this requirement has been removed.

The failure pattern owners describe
The most persistent complaint across these 143 narratives is torque converter shudder and transmission hesitation in the 2012-2014 Camry with the U760E six-speed automatic. Owners describe a pronounced shudder or vibration between 15–50 mph, especially during gear shifts or initial acceleration, with some reporting complete throttle lag where the engine revs but the car doesn't move for up to 15 seconds. The issue typically appears between 30,000 and 110,000 miles.
Toyota addressed this via two limited programs: a 2014 software update (LSC E03) and a 2014–2015 warranty enhancement (ZE5) covering torque converter replacement, additional magnets, and software. However, owners report the software fix alone rarely resolved the problem, and many missed the deadline—the enhancement expired after 8 years or 150,000 miles from first use. When warranty expired, repair costs ran $2,200–$4,500 for torque converter replacement or $7,000+ for full transmission replacement. Some owners reported transmission failure within months of torque converter replacement, with dealers claiming unrelated component failure not covered by the enhancement.
Secondary issues include reverse-gear hesitation, transmission downshift at highway speeds causing stalling, and throttle unresponsiveness despite acceleration attempts. Owners consistently report no warning lights, dealers unable or unwilling to replicate issues during diagnostics, and Toyota refusing coverage after warranty deadlines. No official recall was issued; Toyota treated the problem as a warranty enhancement program instead.

Failure modes owners describe
Torque Converter Shudder with Acceleration Delay
Transmission shudders and hesitates during acceleration, particularly between 15-50 mph, when shifting gears (especially 3rd-4th or 4th-5th), or when pulling away from stops. The shudder feels like running over a rumble strip or a manual transmission slipping. Hesitation lasts 2-15 seconds before vehicle jerks forward. Does not produce warning lights. Owners report safety risk when merging or crossing intersections.
When: Typically appears between 70,000-110,000 miles; some reported as early as 30,000 miles or at 94,000+ miles. One owner reported it at 2-3 years of ownership.
Symptoms owners cite: Shuddering or vibration between 15-50 mph; Hesitation or delay in acceleration (2-7 seconds common); Hard jerk after hesitation resolves; Slipping sensation; vehicle stays in neutral momentarily; Worsens during turns or lane changes; No warning lights illuminated; Worse in winter or on cold starts; Can be temporary masked by manual downshift or hard acceleration
Codes mentioned: P2109
Repairs/costs cited: Toyota Warranty Enhancement program ZE5 covers: torque converter replacement (~$2,200-$4,500), transmission pan magnet replacement, and software update. Dealers also performed Limited Service Campaign (LSC) E03 (software-only update) starting October 2014. Many owners reported the software update alone did not resolve the shudder. Torque converter replacement cost $2,200-$4,500 out-of-pocket if outside warranty window. Transmission replacement (remanufactured) $7,116 at dealer; rebuild at independent shop $3,800. One owner reported transmission failure occurred within months of torque converter replacement.
Recalls/TSBs owners mention: Toyota issued TSB 008612 (June 2012) and Technical Service Bulletin (service advisory 2017) for known torque converter issue. LSC E03 issued October 2014 for software update only. Warranty Enhancement Notification (WEN) ZE5 issued November 2014, covering 8 years from first use or 150,000 miles, whichever comes first. Some dealers reportedly performed LSC E03 instead of full ZE5 coverage (torque converter replacement) despite owners bringing ZE5 letters. Toyota declined to honor warranty enhancement if deadline expired or warranty already lapsed. No recall issued; branded as 'warranty enhancement' program.
Transmission Failure Following Torque Converter Replacement
Transmission develops severe vibration, slipping, or complete failure within days to three months after torque converter replacement under warranty. Owners report vibration between 30-40 mph after repair, with transmission diagnosed as failed. Dealers claim transmission cooler failure or other components responsible, not related to torque converter work. However, no other faults were diagnosed at time of original repair.
When: Occurs within 3 months (sometimes less than a few hundred miles) after torque converter replacement at higher mileage (105,000-106,000 miles reported).
Symptoms owners cite: Vibration or shuddering 30-40 mph after repair; Complete transmission failure or slipping; Loss of motive power; No warning lights initially
Repairs/costs cited: Transmission replacement required; warranty enhancement does not cover secondary failures. Full transmission replacement ~$7,116 at dealer. Owners report dealers claim transmission cooler failure is separate and not covered under torque converter warranty work.
Recalls/TSBs owners mention: Toyota WEN ZE5 covers torque converter replacement only; secondary transmission damage blamed on unrelated components (transmission cooler) and not covered under warranty enhancement.
Acceleration Unresponsiveness (Throttle Lag)
Vehicle exhibits extreme delay in throttle response or fails to accelerate when pedal is depressed, particularly at highway speeds or during merging. Engine revs but car does not gain speed for 1+ minute, or accelerates in hard jerks. Some owners report vehicle stays in neutral or slips during acceleration attempt.
When: Can occur as early as 1,000 miles (at purchase) but commonly reported 80,000+ miles. Persistent or worsening over time.
Symptoms owners cite: No acceleration response despite full throttle; RPMs rise but speed does not increase; Vehicle stuck at 40 mph unable to merge; Hard jerk when acceleration finally engages; Intermittent occurrence (every 1000 miles reported); Vehicle rolls backward when transitioning from brake to gas on flat ground; Dangerous on highway merges and lane changes; No warning lights
Repairs/costs cited: Software updates (LSC E03) performed at dealers but did not resolve the issue. Some owners attempted transmission fluid flushes at independent shops; temporary improvement noted but recurred at higher mileage. No permanent fix identified outside of torque converter replacement.
Recalls/TSBs owners mention: Toyota issued LSC E03 (software update) October 2014, but owners report this alone does not resolve throttle lag. Some dealers claim vehicle 'operates as designed' despite owner demonstration of problem.
Transmission Downshift and Stalling
Transmission suddenly downshifts at highway speeds, causing abrupt speed reduction, stalling, or shudder. Vehicle may drop to low gear unexpectedly, jerking occupants or losing motive power entirely.
When: Reported at 35,000-98,000 miles.
Symptoms owners cite: Sudden downshift at speeds above 50 mph; Vehicle shudders and vibrates after downshift; Abrupt speed reduction; Engine stall without warning; Loss of motive power
Repairs/costs cited: No permanent repair identified in narratives. Owners report dealers unable to diagnose cause.
Recalls/TSBs owners mention: Manufacturer notified but offered no assistance. Cause of failure not determined by dealers.
Reverse Gear Malfunction
Vehicle hesitates or fails to enter reverse properly. When shifted to reverse, car does not move or creeps backward slowly as if brake is applied. Owner must apply hard throttle to move backward, causing vehicle to lurch abruptly. Vehicle jerks to stop without brakes applied.
When: Intermittent; reproduced at dealer lot after 48 minutes of driving and parking.
Symptoms owners cite: Reverse does not engage normally; Slow creep backward despite neutral-to-reverse shift; Feels like brake is on; Requires hard throttle to move; Sudden lurch backward when gas applied; Jerk to stop without brake input; Intermittent behavior; hard to reproduce
Repairs/costs cited: No diagnostic trouble codes found on scope tests. No permanent repair documented.
Recalls/TSBs owners mention: Toyota has no explanation; dealer unable to replicate persistently or find diagnostic codes.
Brake Actuator Grinding Noise
Grinding or odd noise heard from brake actuator when transmission shifts from first to second gear. Noise occurs every time vehicle starts and shifts into second, regardless of braking. Toyota dealer claims this is normal operation (brake actuator performing a pressurization test).
When: Occurs with every vehicle startup and first-to-second gear shift.
Symptoms owners cite: Grinding or odd mechanical noise from brake area; Noise during first-to-second gear transition; Noise present on every startup; Persists regardless of brake pedal frequency
Repairs/costs cited: No repair offered; Toyota claims noise is normal operation.
Recalls/TSBs owners mention: Toyota technical support claims brake actuator pressurization test is normal operation after first-to-second gear shift. Deemed not a safety concern despite owner concern given Toyota's past brake actuator safety issues.

What owners are reporting 3 most recent
While driving on any road between 20 and 40 MPH, 3rd and 4th speed, the transmission shudders and while pressing the gas, the vehicle hesitates. Sometimes it is somewhat clear to accelerate, other times it feels like you are fighting a wall that will not move. I believe from what I have read that it has to do with the ECU and a possible faulty torque converter. This should be looked into by…
Tl* the contact owns a 2012 Toyota camry. While driving approximately 35 MPH, the vehicle began to shake and hesitate. There were no warning indicators illuminated. The contact stated that the failure occurred for at least three years. The vehicle was taken to an independent mechanic and they determined that the transmission failed and needed replacement. The dealer and manufacturer were not…
Ever since I purchased vehicle back May 2016 with 24K miles on it (currently has 107k miles on it) the car has been vibrating between 35mph - 45mph. I took it to the dealer over 3 times within 30 days of purchase and they couldn’t figure it and replaced tires. They said it vibrates because roads are uneven. Didn’t feel like dealing with dealership and left it at that. Last year in 2021 I decided…
