I have had my new Canyon for about a month now and love it. I made the switch to GM from an '04 Dakota I had for 11 years. Making the change from a 4.7L V8 to a 3.6L V6 in a mid-size truck is hardly noticeable with the VVT engine. However, I have noticed some slight hesitation or gear searching when going up an incline or from simply letting off the gas on a level road and then giving it gas again. The truck seems to struggle to find the proper gear sometimes. It's almost like the computer is trying too hard to find the most fuel efficient way to deliver power. (Coming from my old V8, when I hit the gas I expect power not hesitation then power). I wanted to reach out to forum members to get some insight and opinions on whether or not this is something others are experiencing or a unique issue I'm having or if this is to be expected from the 3.6L VVT. Thanks!

How many miles? The transmissions go through a learning phase

Ya it's probably still in learn mode. My '14 Silverado's trans acted a little weird at first. It would shift hard, but then after somewhere between 1K and 2K miles the trans is smooth as silk and haven't had any problems since then which I have just under 11K on the truck now. Also I'm sure your trans has a TQ management like mine where it will seem to hesitate and not give full power from a stop and that's to protect the trans and axles from dumba**es like how I use to drive.

Adam is there any other info you can give about the new truck? Likes, dislikes. I'm pretty sure a Canyon or Colorado will be my next truck. My biggest concern is interior room and ride quality.

Steve: Ride quality is top notch. The steering, turning raidius and responsiveness is very tight, making it a nimble vehicle in the city. The 4wd auto feature is convenient and capable in the last few snow storms we had here. As far as interior room... I think it's got ample room. I'm about 6' and have had adult passengers in the back with no complaints. (compliments actually). Overall I love the truck.

Keep us updated on this issue, I haven't seen anything you are experiencing on the internet with regards to these new trucks, still too new.

Update

 

Here's what the manual says about the shifting issues I'm experiencing...

 

D (Drive) can be used when towing a trailer, carrying a heavy load ,driving on steep hills, or driving off-road. Shift the transmission to a

lower gear selection if the transmission shifts too often. Down shifting the transmission in slippery road conditions could result in skidding. See“Skidding”

under Loss of Control on page 9-5 . The vehicle has a shift stabilization feature that adjusts the transmission shifting to the current driving conditions in order to reduce rapid

upshifts and downshifts. This shift stabilization feature is designed to determine, before making an upshift, if the engine is able to maintain vehicle speed by analyzing

things such as vehicle speed, throttle position, and vehicle load. If the shift stabilization feature determines that a current vehicle speed cannot be maintained, the

transmission does not upshift and instead holds the current gear. In some cases, this could appear to be a delayed shift, however the transmission is operating normally.

The transmission uses adaptive shift controls. The adaptive shift control process continually compares key shift parameters to pre-programmed ideal shifts stored

in the transmission’s computer. The transmission constantly makes adjustments to improve vehicle performance according to how the vehicle is being used, such as with

a heavy load or when the temperature changes. During this adaptive shift control process, shifting might feel different as the transmission determines the best settings.

When temperatures are very cold, the transmission's gear shifting could be delayed providing more stable shifts until the engine warms up. Shifts could be more noticeable

with a cold transmission. This difference in shifting is normal.

I just bought a Canyon and have around 800 miles on it. I am glad I read it is still in learning mode. I am having the same transmission issue: where it is not sure it knows when to shift. THere have been a couple time it was a very hard shift that kind of surprised me.

So, I am at a little over 1100 miles and the transmission is getting better. I have not had any surprise shifts and it seems to be getting smoother except on the entrance ramp to the highway - still learning...

Just wanted to for warn everyone that GM posted bulletin #PIP4112Q regarding Sag or Hesitation on Acceleration. It was posted on September 16, 2015. My 2015 Colorado LT is experiencing moderate to severe hesitation concerns. It's progressively getting worse. I first brought it back to the dealership to have it checked out around 4500, 10,000, and 12,000 miles. Each time they claimed they can't do anything because the diagnostics reveal no trouble codes, although, per aforementioned bulletin, there's proof that a problem exists. I inquired if it could be a mechanical issue, but they refused to because no diagnostics produced no codes/proof. Therefore I contacted GM regarding the concern and am in a tussle right now with the issue.

Going through the same thing now with GM. I don't buy the whole "It's normal operation of the vehicle" response. I have since opened a case with NHTSA. I don't think this shifting issue is safe and hopefully GM will have to address the issue with a recall or update of some sort after a federal investigation. I'll post any progress.

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.

      Bridgestone vs Goodyear tires?

      By Vu1can · Posted

      Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.

      maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...
