# Service bulletin N192268181

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

Emissions Recall. General Motors has decided to conduct a voluntary emissions recall involving certain vehicles equipped with a 2.4L engine and certified to the EPA Bin 4 emission standard and the California Cleaner Federal Vehicle option of Bin 4 emission standard. The performance capability of the vehicle?s catalytic converters may have degraded, such that efficiency is reduced. In addition, the oxygen sensors may provide inaccurate information to the engine control module which manages engine combustion air\-fuel ratios. If these conditions occur, tail pipe emissions may exceed allowed limits, without providing any notification to the driver. The malfunction indicator lamp \(check engine light\) will not illuminate. Dealers are to replace both catalytic converters and both oxygen sensors.

Emissions Recall. General Motors has decided to conduct a voluntary emissions recall involving certain vehicles equipped with a 2.4L engine and certified to the EPA Bin 4 emission standard and the California Cleaner Federal Vehicle option of Bin 4 emission standard. The vehicle?s post\-catalyst oxygen sensor may provide inaccurate information to the engine control module, which manages engine combustion air\-fuel ratios. If this condition occurs, tail pipe emissions may exceed allowed limits, without providing any notification to the driver. The malfunction indicator lamp \(check engine light\) will not illuminate. Dealers are to replace the post\-catalyst oxygen sensor.

- [PIP4112S](/bulletins/10137182.md), 2018-05-21, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE. This Preliminary Information communication provides information to the technician of a complaint of a sag or hesitation when accelerating. The concern is present when coasting at low speeds of less than 15 miles per hour and then aggressively applying the throttle, or after making a hard stop followed by an aggressive throttle. This concern may also be present while crusing at highway speeds and then an aggressive increase in throttle.This is considered normal operation of the vehicle the throttle is delayed and opened slowly up to .7 seconds to help minimize driveline lash and clunking or will have approximately .5 seconds of zero torque to allow the transmission to shift to downshift.
