In july 2016 I was cresting the top of a hill when another vehicle pulled out in front of me causing me to hit my brakes. Upon braking and deceleration, I felt the car momentarily try accelerating through the brakes. This freaked me out and I pulled over to try and figure out what had happened. Checked my floor mat and everything was locked in place as it should be. So I started my car back up,…

What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 9 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: 2016 Camry powertrain complaints span excessive oil consumption leading to engine failure, transmission hesitation and power loss that dealerships dismiss as normal, unwanted movement while parked, unresponsive accelerators, and recurrent brake/ABS failures. Critical safety issues remain unresolved after multiple dealership visits, with Toyota often declining assistance or blame-shifting to driver error.
Owners document two major powertrain failure patterns in 2016 Camrys. First, excessive oil consumption begins around 120,000 miles despite regular maintenance, with one quart disappearing per week. Owners also report grinding noises and sluggish acceleration; one engine completely failed by 130,000 miles after dealerships initially overlooked the worn piston rings. Second, transmission response is consistently delayed or erratic from new—the vehicle hesitates when accelerating from stops, lurches unpredictably, loses power entirely during normal driving, or hangs at 1500 RPM during deceleration. Dealerships uniformly tell owners this is normal operation or cannot duplicate the problem, despite it recurring hundreds of times.
Additional safety issues include unwanted vehicle movement while parked (shifting out of Park at 5,000 miles in one case, causing injury), unresponsive accelerators requiring hard braking to avoid collisions, and one incident of momentary acceleration through applied brakes. Engine sputtering at 66,000 miles, torque converter issues, brake system failures with recurring ABS warnings and unexpected stalling, and transmission fluid leaks also appear. Minor issues include HVAC blower failure after four years and constant road noise from day one. Owners report Toyota denies fault or assistance across nearly all cases, often blaming driver error or calling behavior "design-intended."

Failure modes owners describe
Excessive Oil Consumption and Piston Ring Failure
Engine consumes oil at high rate without visible leaks. Owners report one quart per week or worse under normal driving. Diagnosed as worn piston rings leading to catastrophic engine failure in some cases.
When: 120,000–130,000 miles typical, despite regular maintenance and proper oil change intervals
Symptoms owners cite: One quart of oil consumed per week; Sluggish acceleration; Grinding noises; Dipstick reads dry well before next scheduled oil change; Complete engine failure at high mileage
Repairs/costs cited: Dealership diagnosis noted worn piston rings. Engine replacement required in reported case due to failure.
Recalls/TSBs owners mention: Toyota has issued recalls for similar engine defects in other vehicles but not for 2.5L engines in 2012–2017 models. Dealerships minimized or overlooked the issue.
Transmission Delay and Hesitation / Power Loss
Inconsistent transmission response during acceleration and driving at various speeds. Vehicle hesitates, lurches, loses power, or feels sluggish when driver expects normal response. Dealerships report this as normal operation or transmission searching for gear.
When: From new or within first few months; occurs intermittently during normal city and highway driving
Symptoms owners cite: Delayed acceleration response at traffic lights and during merging; Transmission shifting instability; Sudden power loss or lurch as if shifting from neutral to first gear; Sluggish acceleration with fluctuating boost and hesitation; Engine revs with little forward motion; Tachometer hangs at idle or jumps around 1500 RPM when decelerating
Codes mentioned: P1604 - STARTABILITY MALFUNCTION, P2610 - ECM/PCM INTERNAL ENGINE OFF TIMER PERFORMANCE
Repairs/costs cited: One case noted dealership suspected faulty ECM; Toyota denied repair approval citing driver error. Multiple dealership visits returned no resolution; several stated 'normal operation' or could not duplicate.
Recalls/TSBs owners mention: Toyota denied ECM replacement citing driver error. Dealerships uniformly told owners behavior is normal or design-intended.
Unwanted Vehicle Movement in Park
Vehicle rolls backward or shifts out of park while parked and idling. Two separate incidents reported at low mileage, one resulting in injury to owner and vehicle striking a light pole.
When: 5,000 miles and 15,000 miles (near-new vehicles)
Symptoms owners cite: Gear shifter moved from Park to Reverse without driver input; Vehicle rolled backward while parked with engine running; Vehicle rolled away while parked and idling
Repairs/costs cited: No repairs documented; manufacturer examined black box data but offered no assistance.
Recalls/TSBs owners mention: Manufacturer notified and examined vehicle's black box but did not provide assistance or remedy.
Unintended Acceleration / Accelerator Unresponsiveness
Two distinct problems reported: accelerator becomes unresponsive when driver depresses gas pedal, and vehicle momentarily accelerates through applied brakes during deceleration.
When: From new (recurring 2–3 times per month); one incident at low speed in parking lot
Symptoms owners cite: Accelerator pedal does not respond when pressed; tachometer stays at idle; Vehicle nearly causes collision due to lack of acceleration response; Vehicle momentarily accelerates through brakes while decelerating; One incident resulted in unintended 5 mph collision in parking lot
Codes mentioned: B1507 - VEHICLE SPEED CONTROL AND IDLE CONTROL RELATED
Repairs/costs cited: No repairs completed. One case involved 20-day investigation by manufacturer and third-party EDR extraction.
Recalls/TSBs owners mention: Manufacturer investigated but found no defect; codes that appeared on initial diagnostic were reported as non-existent after investigation.
Engine Sputtering and Torque Converter Failure
Engine sputters unexpectedly during normal driving. Dealership diagnosis identified need for torque converter replacement.
When: 66,000 miles
Symptoms owners cite: Engine sputters without warning
Repairs/costs cited: Torque converter replacement recommended but not completed by owner.
Recalls/TSBs owners mention: Manufacturer stated nothing could be done to assist.
Idle and RPM Control Malfunction
Engine RPMs hang or jump at specific points during normal operation, particularly during deceleration. Occurs consistently every time vehicle returns to idle.
When: From new
Symptoms owners cite: Engine RPM hangs at 1500 RPM when decelerating; RPM jumps or spikes at 1500 RPM; Occurs every single time on every drive cycle
Repairs/costs cited: No repairs made. Multiple dealerships stated this is normal operation and observed on other new Toyota 2.5L vehicles.
Recalls/TSBs owners mention: Dealerships confirmed behavior is present on multiple 2.5L equipped vehicles and deemed normal.
Brake System Failure with ABS and Traction Control Malfunction
Vehicle jerks abnormally when brakes applied, accompanied by illuminated ABS and traction control warning lights. Vehicle stalls without warning during braking events. Problem recurs after replacement of brake components and ABS system.
When: 157,703 miles (late in vehicle life)
Symptoms owners cite: Vehicle jerks when brake pedal depressed; Abnormal sounds from vehicle during braking; ABS warning light illuminated; Traction control warning light illuminated; Vehicle stalls without warning while driving at various speeds
Repairs/costs cited: Dealership replaced ABS system, brake pads, rotors, and four tires; failure recurred. Additional unknown repairs performed; failure recurred again. Vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer notified but offered no assistance.
Transmission Fluid Leak
Transmission fluid leaking from multiple points in transmission assembly, leaving stains on ground when parked.
When: Mileage unknown; discovered when parked
