"Anything new and improved has all the worst features of the previous version and none of the best ones." --Ashton's Law

It appears that we are going to replace our 2001 Subaru Forester with a 2012.

Why 2012?

It has to do with the width of the body. My 2001 is 68 inches (172 cm) wide. Why does that matter? Parking it at home. the car must fit through a tight space between my house and my neighbor's fence. 2009-2013 Foresters are 70.1 in. (178 cm) wide. For the test drive, we had to drive the car home to see if we could park it. The good news is, we can. Starting in 2014, the Forester width went to 72 in. (183 cm). That makes parking it too tight. I can park such as vehicle, but I'm not the only driver.

Fortunately, the 2012 we found has under 20,000 miles (32,400 km). We looked at a 2013 but it had 3x the distance driven and was already showing some signs of rust underneath. The 2012 underside looks like a new car.

There's a big difference in the headrests from 2001 to 2012. The newer cars have to meet more stringent standards, which makes the headrests less comfortable and they create larger blind spots.

OK, the 2012 has an audio jack for a phone or music player. There's also a cigarette lighter receptacle between the front seats in a compartment that also contains the audio jack. Also. the radio/CD player is mounted higher so you don't have to look down to change stations when a commercial comes on. Now, I can move the adapter that connects an audio plug to a cassette player to my 1999 Toyota, which were' keeping.

The 2001 Forester has one annoying "feature" that was designed out a few years later. The front cupholder would place your cup so that it interfered with the environmental controls. Convenient for reaching for your cup, but it made adjusting the controls impossible. I'm happy to lose that annoyance.

The 2013 model has Bluetooth, but it's about reliability and age, not features.

@TonyTib ...but think about clothes (especially woman's clothing):  what you like today will be gone in what, 6 months?

Don't get me started on woman's clothing... LOL I think the usual cycle is closer to 3 months. I've also found that online retailers who emphasize quality are more likely to keep selling items that I like. I've been known to buy several when I find something that I really like.

@elizabethsimion, Come on, for cars it's not too bad, since it takes a while for them to grow, and it's possible to buy used....but think about clothes (especially woman's clothing):  what you like today will be gone in what, 6 months?

Hi Elizabeth. "One of the problems with keeping a vechicle for 15 years is that the feature set that you've grown to love is no longer available in newer vechicles." Ashton's Third Law: Anything new and improved has all the worst features of the previous version and none of the best ones.  Proven right again! BTW you've put too many C's in vehicle...  (you're overloading it already... :-)

@Measurement Blues I hope to replace the car soon.

 

One of the problems with keeping a vechicle for 15 years is that the feature set that you've grown to love is no longer available in newer vechicles. Including, in my case, the ability to get something with the same interior cargo space in the same exterior dimensions. Fortunately, my parking is not quite as constrained as yours. The "compact" pickup that I bought last year to replace my 2000 Grand Caravan is close enough to the same dimensions and the backup camera helps when I back it in. I still miss being able to get 10 foot lumber inside instead of hanging out the back.

IoT headaches will go beyond sensors

With the latest WiFi security WPA2 issue, so many IoT devices will not be patched. That will leave gaping holes for intruders. No IoT devices in this house.

I had the same problem with my 2001 Forester. Now the check engine light is on all the time due to an emissions problem. But, because the car is over 15 years old, it can pass state inspection anyway. I hope to replace the car soon. It's leaking oil. The problem is finding a replacement that will fit in my parking space. Cars of similar style to the Forester are too wide to fit.

I have an old low mileage Lexus that is ladened with sensors, most of which results in a large red frightening danger triangle lighting up in the instrument cluster.  When alerted, I normally scan for important issues like oil pressure, coolant temp, etc, and then ignore the triangle until I get around to re-reading how to reset.  However, the latest warning is kind of nice.  Knowing the brakes are about due, I purchased new pads and caliper bolts (they are one time use!) about 10K miles ago.  This week, red triangle fires up along with a text display which states "Brake Wear".   I imagine being an older deign, perhaps more tightly integrated, the warnings and diagnostics work pretty well.  I just wish everything did not lead to the rred danger triangle display.  I should add, via internet search I have found a detailed diagnotic menu available, which is probably what the dealer techs use along with OBD data.  This vehicle has a high end fancy audio system, which according to brand forums had a class failure issue that resulted in cash refunds to the original owners.  Mine was evidently never fixed as deep in the secret diagnistics menu it reports a failure within the Audio system.  So I would say there can be decent implementation of smart sensors to avoid information overload, it's up to the product developer.

I remember when my car always signaled with some noise that the oil level is too low. This was really annoying. The garage replaced a control unit for 1000 euros but this could not fix the problem. In the end I have sold the car and changed the manufacturer.

I recently got an emissions control warning light on my 6 year old VW Tiguan. Diagnosed as a leaking fuel cap- they have a sensor for that? I actually believe that I hadn't tightened the gas cap sufficiently- I am guessing there is a sensor for that since just prior to this fault I got the gas cap warning light.   

I have never had a similar complaint on the 13 cars I have owned- but they all have a sensor that I wish could be removed- the excess cash sensor. Whnenver you think you have a little money to put away, your car develops a problem.
