I have notice that when attempting to accelerate eg passing another vehicle at highway speeds or just a city cruising speeds, my truck will drop a couple of gears and do the job just adequately and is quite disappointing. This also happens when city driving. I was told by a friend that there is a bit of a stop on the gas pedal and that if you don't depress it harder to the floor, it will act in this way. So I checked it out in my truck and with the truck off in the driveway, I depressed the pedal to the floor and felt it bottom out......I then pressed further down and heard a CLICK and was able to depress the pedal even further. So next I went for a ride and set the cruise at 55 mph and then floored the pedal....the truck went 8th gear down to 5th and as usual, the rate of acceleration was again adequate and disappointing.....so this time, I did the same test and made sure that the pedal was mashed into the the floorboard and WOW WOW WOW!! That truck went from 8th gear down to 4th gear and the truck screamed like a banshee. I did the same test at 30 mph and got the same good results. Check it out fellas in your own vehicle and see if you can hear the click on your pedal.

Taking it all the way to the floor, that 6.2 pulls and pulls and pulls...it pulls so hard you're at 100 and have to back off before you can blink...

Yep, been that way since 2015. Nice to have when you really need to get out of a hole. I noticed this on my test drive and had to research it a bit before figuring out what it was.

OM calls it:

 

"Kickdown Mode

The accelerator pedal provides an additional downshift after pressing through the kickdown feature.
It requires extra pedal pressure near the end of its travel to engage."

This feature has been on cars for a long long time.

In April 2000 I got one of the very first VW GTI's with the 1.8T and sadly at the time it was an auto.

It had this detent in the throttle back then.

First car I knew of that had it.

Again, this is nothing new on many automatic cars for the past decade or more.

I tried this on my 17 Denali and couldn't get it to"kickdown." Does the pedal height make a difference?

Move them up and try it!

      OCI, not when but why?

      By PunchT37 · Posted

      When I was there, most to all did not have an hour meter. They just did 5000 miles on regular vehicles and 3000 on police stuff. The modern oil change monitors should take into account engine hours, weather, etc. I don`t use the monitor on my stuff. I pull the stick, look at it, smell it, rub it between my fingers, etc. That`s my oci.   I have had many engines. Some bracket race. No problems doing things my way. I was in the mechanic business for 30 yrs or so. I still do things the old school way. Don`t care who laughs at me.   Understand, I was in the main shop. We didn`t do oil changes or tires. We had a service station for that. I don`t remember the hours they used for tractors, lawn mowers, etc. Something in my head says 250 hours.

      I don't know how far back vehicles had hour meters, be it driver accessible or diag accessible but was wondering if there was any rule of thumb your shop came up with in regards to an hour limit on engine oil regardless of the miles on the oil.    I know with construction or farm equipment its almost always based on engine hours for maintenance scheduling as no other metric really applies other than a seasonal time limit that one self imposes on items like engine oil.

      I'm not sure what to say on that mess but I will say that is an odd thing for that mechanic to speculate on as per assuming its been run out of oil a few times as the odds of that engine having instead piled up with a complete seizure would be very high if such events had actually taken place. However there is nothing saying that the oil has ever been changed although once again, what filter was on that engine as that would tell part of the story if its possible to figure out if its a factory installed filter or not. Too many items unknown and a lot of speculation, but regardless of that its one fubared mess that is mind boggling to see for a vehicle that new and its hard to imagine how it ever made it that far in life looking at the top of the engine.    His scanners, I've watched him before here and there and I'd have to say if I recall correctly that some of his scanning equipment is one or two steps up from a child's Exo Sketch 😋

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      CLASS ACTION SUITS?  Does anyone know if there is already a class action suit for the paint - which was to have been fixed, changed in after the 2020 GM vehicles?  Does it look like this?    Just started 3 weeks ago - No help from GM as of yet - Dealer will not assist in speaking with GM on my behalf. Confirmed it is the paint they use along with the way the put it on that causes it to fail.  Clearly a Manufacturer's Defect.
