Service Electronic Throttle Control

[8pack-29]

About 4k miles on my scat pack plus… hit the gas and got a big red lightning bolt “Service Electronic Throttle Control”

Whatever the issue is, this seems to effectively put it the car in limp mode. So I had to putter it all the way over to the dealer with the engine limited to like 2k rpm or something.

Service department refused to give me a loaner or rental… had to make a stink with sales to get a car I could drive home while they figure this out.

Anyone else have this Service Electronic Throttle Control issue and get it resolved? I did a quick search and saw nothing to date.

Sounds like you’re dealing with a pretty lousy dealership. We’ve got one up here that acts the same way, they barely lift a finger to actually help you.

ETC issues can come from a bunch of small things like sensors, wiring, or a loose connector (which is probably what it is but who knows). I really doubt it’s the throttle body or anything big IMO. Too bad they didn’t bother pulling the codes or doing a quick inspection while you were already there. Would’ve given you at least some direction on what’s going on.

Personally, I haven't had it, but I only have reached 2200 miles right now.

Have not seen this either. I presently have 1300 miles on car. later RJD

Unrelated, or maybe related, but there were TWO new RRTs with open recall that needed to be flashed since the one they did at purchase in April. I’d been in, in May and these were not a thing yet, so y’all might want to check with your dealer on these, they don’t show up when I put my vin into anything.

The dealer told me there where no new up dates to add. They did one before I bought the car. I bought my car last day of April. Later RJD

Build date?

Build date?

Sometime in March 2026 according to the door panel. I’d been in to dealer since the ones built on or after March 9 TSBs… so I don’t think it was built before the 9th, if that’s what you’re getting at, but I suppose they could have missed those.

These are the RRTs they plan to flash, which may or may not be related to this issue or the TSB:

(RRT) 26-103
(RRT) 26-110

I can’t find any info on what they entail.

Update:

Got the vehicle back today… they told me they were unable to diagnose why the vehicle went into Limp Mode with Service Electronic Throttle Control message. They claimed there were no diagnostic codes or anything active or stored in the car.

I’m pretty salty about this and am escalating it up to Dodge corporate. Although the car is no longer in Limp Mode and the Service ETC message is gone, it is not reassuring that the service shop cannot tell me why it happened in the first place. They didn’t fix anything it just went away on a power cycle from what I gather and brushed it under the rug in the paperwork.

For those that aren’t aware… the car going into limp mode while navigating traffic is a major safety issue especially if you’re turning across a busy road or merging onto the highway it could cause an accident. It cuts the power and limits you to like 2k rpm and it accelerates like somebody who doesn’t know how to drive a manual is operating the transmission (best I can describe it, jerky and slow).

So yeah, not knowing if that’s going to randomly happen again is not cool. @DodgeCares

Well not a good response from your dealer. Later RJD

Yeah... also had this happen to me due to a software issue. It's really not fun. And of COURSE it was right before one of the busiest and largest intersections in the area. I wasn't sure if the jerky-ness was the limp mode or what was causing the limp mode, but yeah "somebody who doesn't know how to drive a manual" is a good way to describe it. Both embarrassing AND scary!

If it's any consolation it's been good for me so far. Happened around 2k miles and I'm at about 6k now and that hasn't happened again.

What concerns me the most is the dealer is basically choosing to not acknowledge that it even happened with a “customer claims” and then they claim they found no evidence of it despite me showing them a picture of the screen with message, the car physically running in their bay at check-in with the screen and car in limp mode, and the service associate literally getting in the car to turn it off and then another one driving it while it was in limp mode…

To me that is MESSED UP. Idk if they’re (service department) incentivized or compensated more as a service department if they have lower “verified issues” and things that can lead to lemons and recalls or if it’s a Dodge policy or what…. But if dealers are hiding real issues from the OEM to get more kick back or having less items unresolved to get more kick back….

My goodness, I hate to say it, but this is Goodbart’s Law in full flex.

Goodhart’s Law states: “When a measure becomes a target, it ceases to be a good measure.”

A few common examples:

Call center metrics: Measuring “calls resolved per hour” can lead agents to rush or hang up early rather than actually solve problems.

Standardized testing: Using test scores to judge schools can push teachers to “teach to the test” instead of building real understanding.

Code metrics: Rewarding “lines of code written” leads to bloated, unnecessarily verbose code rather than efficient solutions.

Soviet nail factory (apocryphal but illustrative): A factory told to hit a quantity quota made huge numbers of tiny, useless nails; told to hit a weight quota, it made a few giant, useless nails.

Yeah man, that's just how it is everywhere now. It sucks

After it went into that mode, did you shut it down and restart to see if it cleared up?

No, I drove it straight to the dealership when it went into limp mode from my current trip. It’s a huge safety issue so they needed to look at it. I’m not going to try and troubleshoot the car going into limp mode. Even if I had got it “back to normal” on my own with a restart, it’s still not really safe to drive without knowing the cause of the Service ETC message and the limp mode.

I’ve owned about 15 cars of different makes and models and never had a car itself mid acceleration like this did.

I think a lot of this stem from the EV computer which they copied into the six pack and missed taking out issue that the EV had. Just a thought. Later RJD

I’m not sure how much bearing the infotainment and IC computers would hold over something like the car going into limp mode, but I definitely agree there are lots of signs of that being the case with the back up camera image, kilowatt default for power measurement etc.

I would think the ETC/ECU/PCM/DTCM/TCM etc would all have to be completely different components, but I’m not a mechanic and don’t know much about EVs other than the mechanical aspects of them are much simpler than an ICE vehicle with traditional transmission.
