Somebody’s in Trouble-Improper Automotive Heat Treatment

“Honda is recalling a number of 2021 Acura RDX and 2022 Honda CR-V Hybrid  models in the United States over a driveshaft issue. A recall issue notice published by the National Highway Traffic Safety Administration (NHTSA) reveals that a component in the right of left front drive shaft may have received improper heat treatment. This could result in premature wear and if the front driveshaft fails prematurely, the engine will not provide power and the SUVs could roll away if the electronic parking brake has not been set. Involved in the recall are a total of 41 Acura RDX models produced on September 28, 2021 and 238 examples of the Honda CR-V Hybrid built between September 28, 2021 and October 1, 2021. The automaker first received word about the issue from a supplier in late September after suspect parts were assembled with insufficiently heat-treated steel balls for the front driveshaft outboard joint sub-assembly. Reproduction testing reveals that the steel balls could deform from the heat generated by the driveshaft.”
