The 2016 Camry is generally solid transportation, but the 2.5L I4 (2AR-FE) suffers from excessive oil consumption due to piston ring design flaws, leading to catastrophic engine damage if not monitored closely. The hybrid and V6 variants largely avoid this nightmare.
Symptoms: Burning a quart or more of oil every 1,000-1,500 miles, Blue smoke from exhaust on cold starts or acceleration, Check engine light (P0300 misfire codes when rings finally fail), Sudden loss of power or knocking if run low on oil
Fix: Factory defect in piston ring design allows oil to pass into combustion chamber. Short-term: monitor oil religiously and top off every 500-1,000 mi. Long-term requires engine rebuild (piston/ring replacement) at 15-20 hours labor, or short block replacement at 18-25 hours if damage has occurred to cylinder walls. Toyota extended warranty to 10yr/150k for some VINs, but many 2016s fall outside coverage.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Leaks
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: ATF puddles under front of vehicle, Transmission slipping or delayed engagement when fluid gets low, Sweet smell or visible red fluid near radiator area
Fix: Cooler lines that run to the radiator corrode at crimp points or develop pinhole leaks. Replace both lines as a set (they're cheap), 1.5-2.5 hours labor. Critical to catch early before transmission runs dry and cooks itself.
Estimated cost: $250-450
Lower Transmission Mount Deterioration
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive/Reverse, Vibration or shudder during acceleration from stop, Excessive engine movement visible when revving in Park
Fix: Hydraulic lower mount fails internally, causing excessive powertrain movement. Replace mount, 1.5-2 hours labor. Not dangerous but annoying and accelerates wear on other mounts and CV axles if ignored.
Estimated cost: $250-400
Rear Main Seal and Oil Pan Gasket Leaks
Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Oil seepage or drips from rear of engine or oil pan area, Oil spots on driveway after sitting overnight, Low oil level without visible smoke (leaking instead of burning)
Fix: Rear main seal requires transmission removal, 6-8 hours labor. Oil pan gasket is 2-3 hours but often found during rear main seal job. On high-mileage cars with oil consumption issues, sometimes both are leaking AND burning oil.
Estimated cost: $800-1,400
Occupant Classification Sensor (OCS) Airbag Light
Occasional · low severity
Symptoms: Airbag warning light illuminated on dash, Passenger airbag off light staying on with adult passenger, No crash safety concern, but won't pass inspection in some states
Fix: Sensor in passenger seat fails to detect occupant weight correctly. Recall issued for some VINs but not all. If not covered, requires replacement of entire sensor mat in seat, 1.5-2 hours labor. Purely a nuisance issue, not a safety hazard in practice.
Estimated cost: $400-700
Fuel Filter Clogging (High-Mileage)
Rare · medium severity
Typical onset: 150,000+ mi
Symptoms: Rough idle or hesitation under load, Hard starting after sitting, Loss of power on highway acceleration
Fix: In-tank fuel filter isn't a scheduled maintenance item but can clog with debris in higher-mileage examples. Requires fuel pump/filter assembly replacement, 2-3 hours labor including fuel tank drop. Only pursue if you've ruled out ignition and injectors.
Estimated cost: $500-800
Owner tips
Check oil level every 500-750 miles on the 2.5L I4 without fail—this engine will destroy itself if run low
If buying used, get a pre-purchase oil consumption test: drive 500 mi, measure oil usage, walk away if burning more than half a quart
Service transmission fluid at 60k intervals even though Toyota says 'lifetime'—cheap insurance against cooler line contamination damage
Hybrid and V6 models don't have the piston ring problem and are significantly better long-term bets
Avoid the 2.5L I4 unless you can verify no oil consumption history or get remaining powertrain warranty; hybrid and V6 versions are solid used buys.

Southeast Toyota Distributors, LLC (SET) is recalling certain model year 2016 Toyota Camry and Highlander, 2015-2016 Toyota Tundra, Scion FR-S, and tC vehicles. The Load Carrying Capacity Modification Label may not reflect the correct added weight of the installed accessories. As a result, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims for Passenger Cars."
Consequence: An incorrect label may lead an owner to overload the vehicle, increasing the risk of a crash.
Remedy: SET will notify owners, and provide a corrected label for placement over the inaccurate label, free of charge. The recall began on July 14, 2016. Owners may contact SET customer service at 1-866-405-4226.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2016 Avalon and Camry vehicles manufactured November 30, 2015 to March 4, 2016. The occupant classification system (OCS) that activates or deactivates the front passenger seat air bag system may have been improperly calibrated. As a result, the front passenger air bag and the front passenger knee air bag may not deploy as intended in certain crash scenarios. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Consequence: Air bags that do not deploy as intended during a crash increase the risk of injury.
Remedy: Toyota will notify owners, and dealers will recalibrate the OCS, free of charge. The recall began by May 13, 2016. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is G0J.
