This is the end of the road for a transmission: the car stops moving under its own power, or a shop says the unit has to be replaced or rebuilt. Half of the owners here mention a warning light or message, and a quarter mention it happening again or to a second unit.

The 25 vehicles with the most reports

Each row is one model year. The bar is its count of transmission failure reports; the share is how much of that car's complaint file this problem takes up. Bigger sellers draw more reports, so read the share alongside the count. Red dots mark crashes and fires in these reports; amber marks a recall on the same system.

What it is and what to do

The transmission carries the engine's power to the wheels, and without it the car won't drive. Firestone lists the signs of transmission trouble: trouble shifting, a check engine light, slipping or over-revving between gears, shaking or jolting during shifts, a burning smell, noise in neutral and red fluid on the ground. The transmission shudder sheet covers those earlier symptoms.

Across roughly 5,000 complaints on the vehicles this site covers, the median mileage owners give is about 72,000. The 2018 and 2019 Ford F-150 and the 2014 Jeep Cherokee top the list. About one owner in five mentions paying out of pocket or quotes a price, against fewer than one in ten who mention warranty coverage.

NHTSA has opened several investigations into outright transmission failures. PE24-009, opened in 2024, looks at 82 complaints of lost drive from a snap ring coming loose inside the transmissions of 2022 Ram 3500, 4500 and 5500 trucks, and NHTSA learned that a Ram service bulletin already covered the condition. An older case, PE13-029, ended in Nissan recall 14V-142 on some 2013 Pathfinders, after a poorly clamped internal cooler hose could come off. Nissan described the sequence: a warning lamp, then noise and vibration, then loss of power, and drivers told NHTSA the last step came soon after the first. Subaru's 21V-955 and 22V-485 reprogrammed the transmission control unit on some Ascent, Legacy and Outback models after a programming error could let the drive chain slip and break, cutting drive power.

Expect a shop to read the stored codes (Firestone notes the check engine light can flag transmission trouble) and check the fluid, since low, burnt or dirty fluid is one of the first things it points to. Leaks at seals, a cooler hose or the pan come next.

Stop when drive is gone or a transmission temperature light comes on. Firestone's advice for that light is to stop and let the vehicle cool, because driving on can turn a manageable repair into a full replacement. The Nissan case is the argument for acting on the first warning light rather than the last symptom. The Subaru recalls describe losing drive power as a crash risk in itself.

Tell the shop what happened just before it quit: noises, smells, lights, a shudder that had been building. Bring the service history, especially any fluid changes. Look up the VIN on NHTSA's recall site and check the manufacturer bulletins NHTSA posts by year, make and model. If the car is under the powertrain warranty, put the complaint on a repair order now; the FTC says a defect reported in the warranty period must be fixed even if coverage runs out before the repair.
