What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 18 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: 2007 4Runner owners report driveshaft clunking and transmission engagement issues starting as early as 5,000–8,000 miles, including violent lurching and delayed shifts—some requiring transmission replacement by 63,000 miles. These appear to be systemic problems owners describe as widespread across the generation.
Owners describe two main clusters of powertrain problems on the 2007 4Runner. The most common is a driveshaft clunk and lurch that happens at stop-and-go driving, particularly when shifting from reverse to drive or coming to a complete stop. Multiple owners report this occurs as early as 5,000–8,000 miles and persists across higher mileage. When it happens at highway speeds, the vehicle lurches noticeably forward. One owner reports Toyota initially blamed inadequate propeller-shaft lubrication despite that task not being listed in the owner's manual maintenance schedule.
The second issue involves transmission hesitation, loss of engagement, and delayed shifts. One owner experienced transmission failure to engage for 5 seconds when shifting from reverse to drive, with violent engagement afterward occurring randomly over several months. Another reports hesitation on acceleration at 71,000 miles. A third describes torque-converter shudder (the "rumble strip" issue) occurring around 2,000 RPM during 3rd-to-4th and 4th-to-5th gear transitions at around 90,000 miles, which disappears when manually selecting 4th gear.
One owner reports differential problems: front-differential vacuum actuator and transfer-case actuator failure around 49,000 miles, plus a fractured rear differential. One transmission was replaced at 63,000 miles; another needed torque-converter replacement at 71,000 miles. Owners note these issues are widespread across discussion boards for the 2003–2009 generation.

Failure modes owners describe
Driveshaft clunk and lurch at stops
Clunking noise and forward lurch when coming to a complete stop or shifting from reverse to drive. Occurs in stop-and-go traffic and can happen at highway speeds, causing the vehicle to lunge.
When: 5,000–8,000 miles and persisting; one report at 16,000 miles; still occurring at higher mileage
Symptoms owners cite: Clunking noise from driveshaft; Forward lurch or jolt when stopping; Forward lurch when starting from a stop; Feels like being rear-ended; Loud clunking noise on start from stop; Lunge forward in heavy traffic
Repairs/costs cited: Toyota initially claimed propeller-shaft lubrication was the cause, stating it should be lubricated at every oil change, but then admitted this task is not listed in the owner's manual maintenance schedule. Repairs performed by dealers, but details not specified.
Recalls/TSBs owners mention: Toyota initially blamed lubrication; later refused to take action despite multiple reports. Repairs were performed at dealerships.
Transmission delay/loss of engagement
Transmission fails to engage or delays engagement when shifting from reverse to drive. When engagement occurs, it is violent and sudden, causing the vehicle to leap forward.
When: Starting at 35,000 miles, occurring randomly once or twice per month over 6–8 months
Symptoms owners cite: Transmission fails to engage for approximately 5 seconds when shifting from reverse to drive; Violent engagement when transmission finally engages; Vehicle leaps forward suddenly; Occurs randomly (approximately 12 times in 6–8 months)
Repairs/costs cited: Dealer stated they could not duplicate the failure and therefore could not repair it. The vehicle was not repaired.
Recalls/TSBs owners mention: Dealer unable to duplicate; no repair performed.
Transmission hesitation and acceleration lag
Transmission hesitates to respond when attempting to accelerate. One owner reports the vehicle hesitating to accelerate from a stop light.
When: Approximately 71,000 miles
Symptoms owners cite: Vehicle hesitates to respond when attempting to accelerate; Transmission loss of power response
Repairs/costs cited: Dealer diagnosed transmission replacement as needed; independent mechanic diagnosed torque-converter replacement. Vehicle was not repaired.
Recalls/TSBs owners mention: Manufacturer was not notified of this failure.
Torque-converter shudder (rumble-strip issue)
Vibration and shudder felt during gear transitions, particularly around 2,000 RPM when the transmission attempts to lock up the torque converter in 4th and 5th gears. Disappears when transmission is manually placed in 4th gear.
When: Approximately 90,000 miles
Symptoms owners cite: Rumble or vibration at end of 3rd gear around 2,000 RPM; Vibration during shift to 5th gear; Issue disappears when transmission placed in 4th gear instead of Drive
Repairs/costs cited: Owner's plan was to check fluid level and lubricate zerks; uncertain whether reflash could resolve the issue.
Transmission replacement at early mileage
Transmission required full replacement at 63,000 miles. Oil-pan system also required replacement. Toyota initially denied warranty coverage and charged labor despite being out of warranty.
When: 63,000 miles
Symptoms owners cite: Transmission failure requiring replacement; Oil-pan system failure
Repairs/costs cited: Transmission replaced; oil-pan system replaced. Toyota covered transmission cost but charged labor out of warranty.
Recalls/TSBs owners mention: Toyota covered transmission cost but charged labor. Owner suspects this is a known issue with the model year.
Front and rear differential failures
Front differential vacuum actuator and transfer-case actuator failed. Rear differential fractured, producing abnormal noise.
When: 49,412 miles
Symptoms owners cite: Four-wheel drive failed to engage when prompted; Four-wheel drive warning indicator illuminated; Abnormal noise from rear differential; Fractured rear differential
Repairs/costs cited: Front differential vacuum actuator replaced; transfer-case actuator replaced; rear differential repaired.
Recalls/TSBs owners mention: Manufacturer was notified of the failure. Repairs performed at dealer.
Excessive heat in gear-shift area
Plastic trim around the gear-shift area becomes excessively hot during stop-and-go driving, reaching approximately 50°C even with air conditioning active.
When: During stop-and-go traffic
Symptoms owners cite: Plastic around gear-shift area becomes very hot (~50°C); Occurs in air-conditioned cabin

Common questions
How serious is the powertrain problem on the 2007 Toyota 4Runner?
It's a documented issue but not catastrophic. 10 complaints have been filed. Repairs average $2,500 and most owners catch it before it causes a breakdown.
At what mileage does the powertrain typically fail?
Across the 9 complaints that reported odometer mileage, most powertrain failures cluster between 8,000 and 71,000 miles, with the median around 49,412. A quarter of owners report trouble before 8,000; a quarter make it past 71,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
