NHTSA Data Dive 3: 117 Models Ranked By Rate Of UA Incidents

And the data beat goes on. I asked Edmunds if they had updated model information to filter out the spike of UA reports to NHTSA after the 9/29/09 Toyota mat recall in order to improve my attempt at coming up with a model-specific UA rate. Not only did they oblige, but they already did all the work! A big hat tip to Edmunds, who has taken a lead in the quest to make sense of the data as well as the whole UA fiasco.

A note of explanation from Edmunds:

Attached are the UA complaints against sales by Model for MY2005-2010 and complaints received through 9/30/2009. A couple things to note about our “complaints per 100k sold” measure: if the model sales was less than 30k, then we excluded it from the list and if the model sales was between 30k and 100k, then we extrapolated the complaints to 100k.

Furthermore, I removed a few cars that had very low UA reports, generally less than four. But I left other in with low numbers because they were essentially “twins” of other models (Fusion/Milan), in order to test how reliable and consistent they are between the. I’m happy to see that generally that is the case: (Grand Cherokee: 7.57; Commander: 7.30); (Fusion 2.91; Milan 3.18) (Vibe 2.85; Matrix 2.75).

Obviously, the same question as to the Panther triplets comes up: they’re all high, but by varying degrees. And of course the biggest on is the discrepancy between the ES 350 (32.03) and the very similar Camry (6.52).

One more minor note: the Lexus LS 430 has an old-time bottom-hinged accelerator pedal, so mat entrapment is not an issue with it. And it hasn’t been implicated with a sticky pedal either. So in its case it must either be human error or…

Finally, the next step would of course to cross tabulate both sides of this chart to specific model years, since awe saw in our previous post how much variation there is from year to year. And then…

Then explain how the 300 is on the list, but not the Magnum, Challenger, or Charger.

      You're making me wonder again about driver demographics. Are 300s being sold to Lee Iaccoca's age group or to Snoop Dog's? There is an elderly coupe that goes to our local Catholic church and shows up in a DUB edition 300. Seeing them pull up always makes me chuckle.

    Interesting stat about AT/MT cars having the same UA rate. Do MT drivers find that the clutch is also disabled in such occurrences?

  • Ronin The very asking of the question "Are Plug-In Hybrids the Future?" is an interesting one. Because just 2 or 3 years ago we'd be asking- no, asserting- that E cars are the future. We're no longer asking that question.
  • Peter Benn There apparently were some K-code 4-dr sedan Fairlanes. Collectible Automobile Apr 2024 has found a '63 500 with HD 3/spd.
  • Mia Hey there!I recently stumbled upon the Crack Eraser DIY Windshield Repair Kit (check it out here: https://crackeraser.com/collections/diy-windshield-repair-kits) and decided to give it a shot on a small chip in my windshield. I have to say, it worked like a charm! Super easy to use, and it saved me a trip to the professionals. If you're dealing with a similar issue, this kit is definitely worth considering. 😊
  • Rust-MyEnemy Whoa, what the hell is wrong with Jalop1991 and his condescension? It's as if he's employed by Big Plug-In or something."I've seen plenty of your types on the forums....."Dunno what that means, but I'm not dead keen on being regarded as "A type" by a complete stranger"" I'm guessing you've never actually calculated by hand the miles you've driven against the quantity of gas used--which is your actual miles per gallon."Guess again. Why the hell would you even say that? Yes, I worked it out. Fill-to-fill, based on gas station receipts. And it showed me that a Vauxhall Astra PHEV, starting out with a fully charged PHEV battery, in Hybrid mode, on my long (234-mile) daily motorway daily commute, never, over several months, ever matched or beat the economy of the regular hybrid Honda Civic that I ran for a similar amount of time (circa 5000 miles)."You don't use gasoline at all for 30-40 miles as you use exclusively battery power, then your vehicle is a pure hybrid. Over 234 miles, you will have used whatever gas the engine used for 200 of those miles."At least you're right on that. In hybrid mode, though, the Astra was using battery power when it wasn't at all appropriate. The petrol engine very rarely chimed in when battery power was on tap, and as a result, the EV-mode range quickly disappeared. The regular hybrid Civic, though, deployed its very small electric reserves (which are used up quickly but restore themselves promptly), much more wisely. Such as when on a trailing throttle or on a downward grade, or when in stop-start traffic. As a result, at the end of my 234 miles, the Civic had used less gas than the Astra. Moreover, I hadn't had to pay for the electricity in its battery.I look forward to you arguing that what actually happened isn't what actually happened, but I was there and you were not."Regardless, that you don't understand it appears not to have stopped you from pontificating on it. Please, do us all a favor--don't vote."You really are quite unpleasant, aren't you. But thanks for the advice.
