OTA Updates
Ever since Tesla introduced the idea of over the air (OTA) software updates with its Model S sedan, the rest of the industry has been scrambling to catch up. Ford and GM will reportedly be ready with the 2020 model year, and the last 6 weeks or so have truly provided the evidence that it is sorely needed, now.
In that time, 10 recalls have been issued impacting 2.8 million vehicles, each of which was software related and all potentially safety issues.
The industry has plunged headlong into computer control of just about everything, without considering improving the methods for upgrades, recalls or clever problem solving. For instance, when Tesla’s sedans were striking debris in roadways and damaging battery packs, part of the fix was an over the air software change that literally raised the vehicle’s height in relation to the road.
The Recalls
The 10 current recalls include a software issue that causes the low fuel warning light to not come on when fuel is actually low, which could lead to a driver running out of fuel.
The second and eighth issues cover hybrids. The first can actually result in a fire because of unburned fuel, while the second can lead to a stall. And there’s never a good time for a stall.
The third is a transmission calibration issue that can lead to stalling.
The fourth involves air bags, which is particularly galling given the attention paid to these devices over the last few years.
The fifth is a stuck purge valve that starts with the programming of the Powertrain Control Module.
Numbers 6, 7 and 9 revolve around the Electronic Control Unit, one of which hits the air bags again, while the last one includes another fire risk.
And finally number 10 leaves a back up camera inoperable.
The central issue across the board is software, and as cars become more and more computerized, you can bet that these issues will increase as well. But at legacy manufacturers, electronic systems have been added piece by piece with essentially no central core in control and no consideration given to over the air connectivity. Thus pretty much every recall requires the vehicle to be taken to a dealer for updates.
And while we see this as a safety and convenience issue for drivers, according to IHS Automotive manufacturers stand to save over $30 billion in recall costs by 2022 if over the air updates can be implemented.
The Risks
Hacking risks exist in vehicles already and will be exacerbated by over the air connections. These issues simply need solutions and cannot be an excuse to avoid the bigger fix. But we would caution manufacturers not to follow the examples set by our computers and cell phones.
We have all experienced odd behavior from our devices only to discover that an update had been downloading while the devices were in use. This simply cannot happen in our cars. The announcement shown in the picture of a Tesla screen would be more than sufficient to cover an update.
And we are assuming that new software was not actually downloaded before the message was shown. And if this is not the case, it damn well should be. Gumming up the works with a download while a car is in use is down right dangerous.
Make no mistake, software and software updates are a dicey game to play with moving vehicles. Aside from the recalls noted, a September software update by Tesla disabled their Auto Pilot system rather than improving it. Other manufacturers, where they have the capability to update their infotainment centers, have experienced similar problems. Mistakes of this type could impact a far more critical system in any car at any time.
Now we’ve clearly oversimplified the issue. It’s not easy to turn around the methods used by existing manufacturers or to control the cost of those changes and the over the air data delivery. Also as we’ve seen too often in the industry, there are no standards for something that a few years ago simply wasn’t even on anyone’s mind outside of Tesla.
But leaving a driver in a car that has a fire risk or other safety issue that was likely caused by, and can be fixed by software changes is not acceptable in a computerized and wirelessly connected world.

Does Your Owner’s Manual Have a Troubleshooting Guide?
How Deep Is Your Owner’s Manual?
We’ve done a couple of owner’s manual rants and got to thinking about where the average driver might look in their respective manual if they ran into trouble, specifically with dead or dying key fobs.
So, we examined a sampling of owner’s manuals from BMW and Mini, Fiat Chrysler, Ford, GM, including Buick, Chevrolet and Cadillac, Honda and Acura, Kia and Hyundai, Land Rover and Jaguar, Mazda, Mercedes Benz, Nissan and Infiniti, Subaru, Toyota and Lexus, Volkswagen and Audi and Volvo. And since we are adding this commentary, you can probably guess the results.
So lets set some parameters. Our first thought is to look for Troubleshooting chapter. So, result #1 is that not a single one of these 25 manufacturers have a chapter with this title. Only 3, Mazda (right), Toyota and Lexus, even use the word Trouble. Emergency, Roadside or Breakdown are most likely to be found, and this is a pretty short hurdle. VW raises the hurdle, with a Do It Yourself chapter that includes flat tires and dead batteries, etc. that tend to be found in the Breakdown chapters from other manufacturers.
To Index or Not to Index
Next, we looked to see if there was an index to resort to. Several, BMW, Land Rover, and Ford, for instance, have no indexes at all. So if someone out there is from these companies, please consider adding that in. On the other hand, the indexes we did find were no help at all with dead key fobs.
So, back to the our troubleshooting-like chapters. Once inside, only Honda/Acura, Toyota/Lexus and Subaru got this right! Setting aside for a moment the fact that the owner’s manual is most likely inside the car and the driver locked outside, at least if the driver manages to get the car open, he or she will be able to get started.
The Honda and Acura chapters point to an issue with the key fob being weak. This may not be immediately obvious to the operator, but it would be a likely spot to check out if the car wasn’t responding.
Subaru (right), Lexus and Toyota chapters point directly to pages with solutions to issues with the electronic keys. Again, it may not be obvious to the driver that the key fob is the problem, but these manufacturers come the closest to nailing the problem. Titling the sections using something like what to do if the car does not respond to the electronic key would come closest to replicating exactly what the driver is experiencing.
Absolutely none of the other manufacturers point directly to the electronic keys in anything remotely like a troubleshooting chapter. To be clear, they all have the solutions shown, but the driver is left to contend with 400, 500 or 600 pages of information to get to what they need.
So for all of them, walk a mile in your customers shoes and try to think like someone who simply doesn’t understand what is wrong. Then make a Troubleshooting chapter and forget the clever titles like Handling the Unexpected or Volkswagens do it yourself chapter, which is where they keep breakdown assistance.
The closer your cars get to being rolling computers, the more relevant an actual Troubleshooting chapter will be to your customers.
