I bet Toyota has a billion more cars and products on the street than Tesla

Seriously, Tesla produces, what… 4 vehicles? Toyota has been making cars for 75 years and has 14 current models.

You don't understand "rates", do you?

Recalls : New cars sold

Tesla = 55%

Toyota = 191%

They compare total vehicles for that brand sold and recalled in the time frame.

There are a lot of Toyota on the road recalls happen not only for new cars. I think a lot of the recalled Toyota were some before the time frame and that is increasing the numbers.

On the other hand there were basically no Tesla before 2011.

This doesn't change the rate. Toyota was selling cars for longer but also recalling then for longer. Tesla wasn't able to recall cars during that period, but they didn't sell cars either. It's not relevant to interpreting the results.

Ok. Scenario: you sell lots of cars. From say 2000 to 2010 you have an airbag in the cars that in 2012 is shown to have a problem. So you do a recall in 2012. As you just recalled 10 years of production you obviously recalled more cars then you sold in 2012.

That is a problem that a company that basically didn't sell cars before the reference time frame can't have.

We'd have to see the average age of the products that were recalled. In my mind, recalls usually happen pretty soon after a model is released. It doesn't take 10 years for something to need to be recalled. I think it usually shows up in the first two years. I'd have to check though.

The average time between release and recall should decrease, if over-the-air software updates are being considered recalls. Those will only get more common.

The percentages look bullshit to me. They explain this as number of recalls in a given year divided by new registrations, which I’m assuming are registrations of the given make. However, those numbers are not related.

Firstly, newly registered cars most likely will be different models than those affected by recalls. The ratio mixes two different sets of data. At least from what I’ve seen new models are rarely subject to recalls, and the article definitely does not give any evidence to substantiate it’s approach.

Secondly, we get no context of the new registration trends. A brand losing market share will be appearing worse in the statistics than a brand gaining. It looks pretty clear to me why Volvo and Mitsubishi have such high percentages, with this approach.

A more valid statistic but much harder to assess accurately would be the total number of cars a given brand has on the market at the time of the recall.

A possible alternative approach could be to divide the number of recalls for a specific model year by the total number of units produced in a given model year and average them out across whole manufacturer gamut.

Either way the statistics the article presented do not look very trustworthy and seem to favour new and rising brands.
