When Honda and Acura recalled 1.1 million Takata airbag inflators for exploding into pieces, they replaced the defective part with a slightly different version from the same company. Now those are exploding too. The replacement PSDI-5D desiccated inflators were exposed to excess moisture during assembly. This rapidly degrades the propellant and allows pressure to build up over time, turning the inflator into a mini-grenade that explodes during airbag deployment.
The 2014–15 Acura MDX and RLX have a 'collision mitigation braking system' that watches the road and hits the brakes if you’re about to crash. And that’s great when you’re about to slam into somebody’s bumper, less so when the system gets confused by a shiny guardrail that’s 100 feet away
