Anybody else notice funny stuff with the operation of their Trax for instance;

When you put you Trax in ''Neutral'' why does the rear wiper stop working and resume when you put it back in gear or even in ''Park''

When you don't put your seat belt on the blinker chimes instead of clicking

Why does engine braking only work in cruise mode?

I know there must be a logical engineering answer to this....

I don't have cruise on my Trax, but engine braking does kick in when coasting downhill. I haven't noticed the other quirks but will watch for them.

Mine does to a little bit without cruise but it won't downshift to hold it back. When you use the cruise it will let it gain about 5 mph then it will go into engine brake and if it keeps climbing it will actually downshift to try and hold back. It is a great option when you live on a hill like I do.

Well tested this today in both state ''cruise and without''
First I tried with cruise set at 85kph going 90kph in a 90 and when the Trax accelerated to 93 down the hill, the torque converter locked up and the transmission dropped to 5th gear slowing it down all the way to 86 before unlocking the torque converter and shifting back up to sixth where it started to accelerate again down the hill. So I turned around and did the same with no cruise came to the top of the hill at 90 and took my foot of the gas and this time it only accelerated to 93 before the torque converter locked up and Trax fell on engine brake but it acted differently as it did not downshift and also didn't decelerate at all, in fact it went all the way up to 98 when I decided to apply the brake. It definitely acts differently with and without cruise.

This isn't a qwirk, more like a nice to know for people with cold winters. I noticed that when the selector knob of the HVAC is in the windshield defrost position ( mixed or full ''ON'') that heated mirrors and rear windshield defrost get actuated when you remote start your Trax. I don't know yet if it checks outside temperature but I will keep an eye on it. This works differently than my wife's G6.

I guess what I'm trying to say is if you're going to remote start your car in the morning or even after work it is best to turn all 3 knobs fully clockwise.

I really don't think the engine is big enough to hold back the speed that much. There's a long downhill run here where the Trax downshifts itself until it's about 3200RPM @50mph, and I still have to tap the brakes to slow to the speed limit of 45mph. If it dropped down another gear or two it would probably make no difference, except for the engine RPM raising to the point that I would start worrying. It's more of an assist.

Here's and other one I just noticed today, when signaling a lane change you don't have to hold the lever. When you depress it once and let go it automatically flashes 3 times.

I have the 2015 LTZ and I've read in the manual that the seat heaters should come on when remote-started below a certain temperature threshold - but that has never happened...has anyone figured this out?

Just dependant on outside temperature because this morning it was -3°C and I didn't have the defrost selected and rear defrost was switched on when I remote started the Trax.

I was wondering why the turn signals were blinking in the opposite direction 3 times after manually cancelling a turn signal.

I wonder if that can be turned off, my Miata has a choice, I can change it in the car features section on my infotainment screen.

I will take a look at my Buick when I go home tonight, we are still blessed with dry roads and sunshine here in the northeast.

My Miata is the car of choice when the roads are dry.

Haven't seen anything in the menus and I don't know why you'd want to turn it ''off'', kinda neat feature.

New one I noticed today, if you have your front wipers ''ON'' your rear wiper will automatically come on when you put your vehicle in reverse.

I agree - the Trax has very little engine braking. I have some decent hills to go down and I like to try and hold my speed with the transmission and not using the service brakes, but I can't do it in either of our Trax's. These are 10% - 15% grades. If you want a good experience as to what engine braking feels like, go grab a diesel truck... My diesel truck I can hold speed without using the service brakes on 15% grades even towing.

Knowing this, I start out much slower on the big hills in the winter.

An other quirk I have with my Trax is when I press the windshield pisser the wipers only sweep once, maybe this is a problem not sure, My Encore sweeps 3 times. When you're driving at highway speed one sweep just doesn't cut it so you have to turn your wipers on before you spray the windshield. Kind of a pain, the rear wiper sweeps 3 times though go figure.

My 2017 Trax hasn't been nearly warm enough in cold weather. When sitting and idling I have to rev the engine to get heat. This is even after driving 15 minutes. Anyone else?

Yes, the heater is a bit slow warming up even in Southern California. I did find this article for slightly older Trax which sounds like the same quirk.

The energy efficient engines that these vehicle are equipped with may not generate the same amount of heat at idle that the customer may be accustomed to when compared to older less efficient engines. Additionally, depending on extreme cold ambient temperatures, a short drive cycle under light engine load may also not generate enough heat to reach normal engine coolant operating temperatures as indicated by the engine coolant temperature gauge and therefore insufficient heat from the heater outlet ducts.
If there are no DTCs, the engine coolant level is correct and the thermostat is diagnosed as operating correctly, then the comment of the engine is slow to reach normal coolant operating temperatures should be considered as a normal operating condition of these energy efficient engines in cold ambient temperatures.

In cold weather, has anyone else noticed the white/blue cloud forming from the tail pipe? I have a 2017 Trax with 15000 miles. When ever the temp drops to single digits or colder I get a nasty smelling cloud that follows me for a couple miles. Once the engine warms up it stops.

Yeah, mind did that last week at -23°C about -9°F for those who haven't caught up to the rest of the world. I believe it might be the PCV valve that freezes open until it thaws out and sucks oil from the valve cover into the intake. Mine stunk of burnt oil for a while. I guess at those temps we should let it run for several minutes before forcing this little 1.4 to work. Mine hasn't done it since but I thought I blew a gasket or something.
