Alas, all the Acuras produced before 2007 --- including my MDX 2006 --- either flunked outright the recent IIHS rear-collision tests or came close to it. That prompts a question: does anyone know whether the 2006 seats and head restraints can be replaced by the post 2007 MDX ones that passed the tests with flying colors? Michael Here's the link to the IIHS results for Acura: http://www.iihs.org/ratings/head_restraints/headrestraints.aspx?acura

Replying to: gordongordo (Dec 03, 2007 5:39 pm) These IIHS tests have become more-and-more sophisticated and the vehicle designs change more frequently....its not valid to extrapolate results from one model year to next model year. IIHS doesn't do it but many magazines try and do it. It is the main reason I recently did not renew my membership in Consumers Union (Consumer Reports).

Replying to: mecheng1 (Dec 04, 2007 7:52 am) Here's a link to a fairly full description of the IIHS rear-end collision test: http://www.iihs.org/ratings/head_restraints/head_restraint_info.html Please note two things that you queried about: 1) the dummy is the size of an average size man (first paragraph); 2) the speed used simulates a vehicle of equal size (MDX mid-size SUV, for instance) that slams into the test-sled simulating a 20 mph crash. The results for those of us with Acuras made before 2007 aren't encouraging, just the opposite. And a mediocre score is, as I indicated, "close" to flunking. Note, finally please, that in 50 years of driving, I've been in six accidents --- and 5 were rear-end collisions, one (estimated by the police when I myself was in my very large Mercedes sedan) caused by a vehice going around 40 mph. The whole trunk area was pushed way forward, but nobody in the vehicle was hurt. And we didn't have airbags in those days to cushion the sudden jerk forward after the initial brusque jerk backward against the headrest. (The 6th accident was caused by somebody backing out of his driveway as I made a slow right turn into his street.) What are the likely deficiencies in the pre-2007 MDX (to stay with it)?. Most likely, 1) the design and material of the seat, 2) the support material of the head-rest itself (the geometric design gets a "Good" rating), and 3) the seat-belt --- especially how quickly it restrains an occupant when a collision occurs from behind. I do hope that someone knowledgeable about swapping the seats in the 2006 MDX reads this thread and can help me (and no doubt others) see about an exchange to safer seats and head-restraints (and maybe seat belts). Otherwise, my 2006 Acura MDX --- just purchased, certified, 3 weeks ago --- is a marvelous vehicle. Michael |

Replying to: gordongordo (Dec 04, 2007 5:47 pm) Obviously Acura changed something in the MDX design in May of 2007. If you can implement a similar change to you 2006 model...you have it. Since seats of all years passed the "geometry" test with a "G", it may be more than the seat component that needs to be swapped. [You see how Acura made a design change in the middle of the model year in this instance?...lots of the auto magazine and others that quote the IIHS data fail to recognize this and will report that "ALL" MDX's fail this or that test, etc.,etc......lazy journalism]

So am I to surmise that my '04 MDX failed this test because the head rest height is too low? It's adjustable so that mine is hitting the back of my head much higher than what's shown as poor in the diagram.  Anyone else w/ a pre '07 MDX confused by this?
