Enhanced Driver Alert Package

I just bought a 2017 High Country and guess the Lane Keep Assist and forward collision alert do not work as I would have expected. We have a 2013 Terrain  and this is nothing like that.

 

The dealer tells me on this system that there are no visual or audible warnings when you cross the center line. Just the keep lane assist kicks in to attempt to steer the vehicle.  The only time I get the 5 lights on the dash and the seat buzz and/or chime is slow speed when I am pulling into the garage.

 

Further more the only time the forward collision alert kicks in is when you are a few inches from swapping sheet metal with the car in front of you. I tested it doing about 70 with a 50 MPH vehicle in front of me and the forward collision alert never changed from green as I did this and I was pretty close... No warning or anything.  I have the collision alert set to max distance (3 bars).

 

Is this normal on a 2017?  Appears they have changed some over the years.

I have a '17 with the package, ltz. Here are my observations.

The LKA, if you look at your DIC, the LKA symbol will turn orange... That's the only alert you get. If you swerve hard (don't recommend) over the line, the hapatic seat will kick in. Otherwise LKA will just nudge you back in. Also, if it detects your hands aren't on the wheel or you don't give feedback as it nudges, the system will alert to that. Again, I don't recommend testing.

 

The collision detection has 3 sensitivities... Make sure you adjust that. It's really like a last resort type deal. Mine has kicked in with cars doing a left turn in front of me. Speed is city streets for the automated braking.. either way, it still flashes and boosts the brake. I think there is some delta logic happening... It doesn't activate off proximity alone. Seems to be proximity + rate of close.

I was led to believe it was low speed collision avoidance meaning 30mph and under is how it was explained to me.

This is from my manual.

I think we are talking about two different things. I was referring to the low speed collision avoidance)low speed automatic braking. And I believe it works under 25-30mph.  I see now you are referring to just the collision alert in which I do not think slows the vehicle down.  I know the 17’ Tahoe’s have this maybe it has not gotten to the trucks yet.

Yea I am talking about high speed. (FCA)


I did not think the 2017 braking worked at high speeds.

At high speeds it will probably just give you brake booster. I've had mine active... I was needing to cut over two lanes and was close to the car in front and closing quick... But it was a definite if I wasn't moving over I needed to be on the brakes type event. I think it's set when there is a high probability. Not over the top like some systems.

Well it does not seem to work well. I would expect the tailgating warning they talked about in manual at speed.

Disappointing.

It's not so much the following distance but the "closing" rate.

Yep. I was pushing the closing rate hard.

Also keep in mind scrubbing speed at speed is easier than when slow... You have downforce, cooling and well the aerodynamics in your favor. I bet you can do 70-50 faster than you can do 20-0

I was really interested in the advanced safety features, but there was no way I could find an equipped truck in my price range.

My 2018 has it and it seems very random. Algorithms I guess.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thanks @newdude, guess I'll keep looking.  Test driving so many trucks that have obvious things broken, I'm thinking "if they couldn't even be bothered to fix the power seat," what else is broken".   Just drove a 2021 where the power seat motor was grinding/binding and wouldn't do anything but make a terrible sound.   An owner that puts dents on the bumper, doesn't fix a seat motor, and had spotty service intervals (along with missing major services) doesn't give me the best of confidence.   Amazed at the number of people that will finance a $60k+ truck, run it into the ground, then trade with a loan balance (every single one had "loan/lien reported" on the CARFAX at the last year of registration).

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.
