General Motors has issued a product emissions recall for certain examples of the Chevy Camaro and certain full-size truck and SUV models due to an issue related to the engine calibration.
The problem: all vehicles affected by this recall were ordered with the optionally available, dealer-installed performance air intake (LPO RVK or 5W7), however the engine control module may not have been programmed with the calibrations appropriate for the performance air intake.
The hazards: GM did not specify what issues this problem can lead to. However, on the GM Tech Link website, the automaker states that “GM Accessories that require updated calibrations must have the calibrations installed to ensure proper operation of the new accessory components as well as other related vehicle systems.” The site also says that if the proper calibrations not performed following the installation of an accessory, then this “may not only limit system performance, but may also leave the vehicle non-compliant with regional government regulations.”
The fix: GM dealers will be instructed to recalibrate the ECU. These updates will be performed at no cost to the vehicle owner.
Affected components: ECU calibration.
