Service bulletin TSB 25-2174

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some of the vehicles listed in the model statement with approximately 1,000 miles (1600 km) or less on the odometer, may exhibit an intermittent momentary moan noise with an associated vibration when traveling an uphill grade at 50-70 mph (80-112 km/h), while the throttle pedal is slightly depressed (throttle tip-in) without shifting. The vibration may be felt through the accelerator pedal, through the driver's side floor of the vehicle and the steering wheel that lasts for 1-2 seconds. This may be due to momentary excessive slip of the torque converter lock up clutch within the front hybrid drive unit.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
