General observation, example, and questions on cruise control (2022 Ram 1500):

Observation: When vehicle is traveling slower than cruise control is set, when cruise control is resumed, the vehicle will stomp on the accelerator and try to speed up to achieve the set cruise control speed as fast as it can. This is annoying and probably uses more fuel than necessary, especially since I left the house early and am in no rush (haha, yeah right).

Example: Cruise is set at 65 mph and vehicle is traveling at 65 mph. Traffic causes me or the vehicle to slow down below 65 mph, say to 45 mph. When I hit "resume" or the vehicle in front of me is no longer in front of me, the vehicle will go bat out of hell to get back to 65 mph like its life depended on it.

Question 1: Are Ram engineers out of their minds?

Question 2: Is there a setting somewhere for "resume by gradually increasing speed back to set cruise control speed?"

No setting that I have seen ref adjustment of Cruise,. Maybe with AlphaOBD, but nothing at least on MY 19 in Uconnect.

If I hit resume, it will go up to about 2800 RPM or a lil more sometimes to preset, but it is not bone jarring, more like a gradual but get there acceleration, but U will get the opposite also. Say, have cruise set at 52 cresting a hill. If U leave cruise on, going down the hill, the trans will downshift in an attempt to keep it at set speed and rev up your RPM's.

Just about every vehicle out there will hammer the cruise control if there is greater than a 10 mph difference between the actual speed and the set point.

My HEMI powered 2009 Ram would be in Fuel Saver, now known as ECO, would allow the speed on an uphill grade to drop 6 or 8 miles below the set CC speed & then it would give me a surprising, neck jarring burst of speed as it kicked into 8 cylinder mode.

Same as people above. Every car/van/truck I've own at least in last 10-15 years maybe longer has done that.
Best thing to do is use pedal to get back up close the cruising speed and then resume.

Cruise control and adaptive cruise control both do this. I don't like it and I wish I had control over it. I don't know what the thought was behind this but like others, every vehicle I've driven in the past, regardless of brand, has done this.

My wife's 2016 Jeep Cherokee does the same thing in Adaptive Cruise...

My '19 Wrangler does the same. Only thing I can figure is that it's the programing that causes this. I've just learned to cancel the cruise, and do it myself in those situations.

I just ordered my Ram, so I guess I can expect the same with it.

Our other car is a 2017 Lincoln MKZ with adaptive cruise and when it resumes, it's a nice gentle acceleration. Really works good. If i'm on the freeway with the cruise set at 70 and get slowed down by traffic to 60, as soon as i use the turn signal to move to the next lane over, it starts to gently accelerate and when i'm clear of the vehicle ahead it continues to resume to the set speed. Very smooth.

22 PW. Mine is a slow smooth resume. I even sometimes look down at speedo to see if it accelerating because the resume is slower then Im used to.

Im also ALWAYS in selective gear mode, so never in eco mode. Dont know if that makes a difference.

You guys reporting a "slow resume". Yes, I get that also but the variable is the travel speed versus the set cruise speed. If the delta is small, like 5 or 6 MPH, I get a slower acceleration to the set speed but if the delta is much larger, say 15 MPH, seems like the cruise system sets the throttle to darn near wide open to get to the set speed.

What I would like to have is a setting in between full throttle and a slow resume.

Keep in mind, we are all driving the same trucks with the same cruse systems and there should not be any difference in behavior.

There needs to be rate of change limit based on the differential of actual vs requested speed of the vehicle. Then again that could solve one problem but create another.

I beg to differ the trucks reacting the same. I know my EcoDiesel doesn't react as violently as a Hemi but that probably has more to due with it not having to downshift as much as the gassers.

Well. since we're all driving the same trucks, and your experiences are the same as my comparisons to the last 10 trucks ive owned, We'll just let you answer any and all future questions about our identical experiences.

I've owned a few brands over the years. Most of them seem aggressive to me on cruise resumes.

Then I'm pulled into the whole autonomous driving thing... RAM touches on it with it's adaptive cruise control feature, which I have in my 2020 RAM. Not quite a "level 1" autonomous feature, but close. Many cars have adaptive cruise, my wife's Caddy has it too. It also is aggressive, to the point I rarely use it fully. It is my go-to for turning on, but I will take control most often way before it does. The programming of these systems are way too giving to subjective situations and don't do nearly enough to be safe in terms of defensive driving. I see a lot of Tesla videos where too the computer just doesn't do enough to be what it needs to be for safety as the #1 goal. They do good, almost great in 90% of cases, but that's not good enough for me. I tried Telsa once in a test drive. I haven't tried Ford's or GMs auto driving feature yet. I do hear that GM beats Telsa for smoothness though, which would be the goal all car companies need to shoot for. Don't just do it, but do it well and safely.

Is there a pathway to discuss/inform this issue with RAM, or is it safe to assume they review pages like this? I would guess they do not review these forums, but what do I know.

Btw….I do the same “push the peddle down”….to pass slower traffic, while leaving the cruise in sevice. When the pass is complete backing off the gas let’s the cruise drop the speed to the set speed.

Maybe the engine is just trying to hose down/lubricate those roller lifters ? ? ? Kidding

Unfortunately there's no good way to make a vehicle think like a human, it can only react based on what it's programmed. Probably be another 10-15 years before enough real world data is gather to get close to full autonomous driving with the number of unknown variables encountered while driving. Unless the automakers will be held responsible for the "decisions" their autonomous driving systems, responsibility will always fall back on the car owner.

Probably your best course to inform them will be to contact their customer support at the headquarters in Auburn Hills.
