Holy shit, man. You know what!? This area has a huge marder problem. You might be on to something. This is at least something I can ask the mechanic to please look for and rule out.
Suggestions from the other forum have been to monitor the battery voltage next time and to also switch into neutral and see the effect in order to further isolate the problem.
Multiple misfire. Could be from a variety of causes.
Very odd that a code is not being set.
You can see the needle move. lol.
Total gas mileage isn’t super horrible. I work 60km away, which takes about 35 minutes of driving. So I drive the car a little over an hour each day; about 120km round trip, plus incidental mileage around my work. I almost never drive it anywhere else. I fill up the tank about every 4.5 days.
My wild ass guess:
It looks like the car is going into a limp home mode, which should throw a code. I wonder if the PCM isn’t going into a diagnostic mode where it will put the car in that mode, but not throw a code as it’s just a diagnostic test? Something, maybe faulty wiring, could be triggering that diagnostic mode?
I have to say that I really appreciate people who love cars, love driving, and love American Muscle. I do not understand people who view a car as just a utility. Crunchable, recyclable, jelly bean shaped cars, that no one will ever keep longer than a few years and never to become classics. I only live 11 miles away from work and I often wish it was farther away, because of my love for driving.
And roads, god what good roads you have!
I always thought that at speeds like 150 miles per hour and up … that even so much as rolling over a pencil could throw your car off the road and lead to a very dangerous accident. The Autobahn is scrupulously free of pebbles, tree branches, and such? No chunks of rubber thrown off from the tires of big trucks?
And I may assume that the Autobahn is set up so that you see signage for ramps and such many (many!) km in advance? At those speeds, there’s no last-second lane change as you suddenly realize you’re going to miss your exit.

The autobahn is generally free of large debris–tire chunks, wood, or branches and such would be promptly removed by the police or road workers. Once I saw a police stop an entire three lanes of autobahn to remove a piece of wood that was off the shoulder and not even on the road itself.
As far as pebbles and that sort of thing, I don’t think it’s any more free of that sort of thing than any American highway. My father used to say the same thing about driving that fast–“At that speed even a pebble will cause you to lose control” he’d say. I’ve come to find that it’s just not true.
Signs for the exits usually start 1 km back, and then there are signs with hashmarks every 100m starting about 300-500 meters prior to the exit. And that’s usually the start of the exit. You’d think that the autobahn would have long deceleration lanes prior to the actual exit. Quite the opposite, in fact. The autobahn is notorious for extremely short and often nonexistent deceleration lanes. It’s important to slow down before exiting.
In fact, I believe the Interstate system in the United States is much more capable of handling autobahn speeds than the autobahn itself. It’s the strict driving rules that keeps everything safe over here, not the road design.
“Eco mode” is running on 4 cylinders. Maybe your car is going into eco mode when it shouldn’t. It should only go into eco mode at very light throttle.
Regarding running on 4 cylinders, for a moment I almost wondered if there was a lifer issue and it was backfiring or engine braking.
Probably a good sign, thought it’s going to be tough to see if the fuel smells rich while you’re driving.
I’m sure it has the ability to display quite a bit of user friendly information. But I’d be surprised if you could see things like fuel trims (different than air/fuel ration) or O2 voltage. But I could certainly be wrong, I’ve never even been in one of those cars.
Of the ECM is faulty, I have to assume it would start throwing codes or the car would be having more problems than just some odd noises.
If it is misfiring, that should have been enough misfires to turn on the CEL, but even if it’s not, the misfire data is still stored in the computer and easily accessible.
Hell, if it’s under warranty, let them. But I’d probably attempt to rule out other things first, unless the ECU going bad is a common problem on this car.
I’m not sure if the noise would only be noticeable once in a while. The few times I’ve had to fix them, they were either fine one minute, not so much, or they would have a low pitched groaning for a little while until we replaced them. If that’s your problem, maybe they’re just starting to go bad.
Yes, I have a bluedriver that does a really nice job. Last year I bought a bi-directional Autel as well.
How about this for dumb. Last year or the year before I could not get one of my trucks started. It cranked fine, there was spark, there was fuel, the fuel was at the correct pressure, the injectors were getting their pulses. After months of playing with this, I was getting so fed up I was going to, out of frustration, siphon some gas out and set it [the gas] on first just to make sure the stupid stuff was still flammable.
What came out was a translucent white liquid that quickly separated into gas and water.
There was probably 4 or 5 gallons of water and 15 gallons of gas.
It took A LONG time to get all that gas out.
One more point, Bear, don’t get too fixated on one issue. If you convince yourself that it’s a specific thing, absent any real evidence, it makes it easy to start throwing parts at it instead of confirming your suspicions are correct.
I lived in Germany for four years. German drivers can’t get a license until age 18 and go though a pretty extensive training. That said, whenever there is an accident on one of the highways, it’s usually spectacular. I saw a Porsche disintegrate into just so much shrapnel.
IIRC the SRT versions of the Hemi- Hellcat included- do not have the cylinder deactivation hardware.
Sounds like if you’re on the Autobahn … you’d better know exactly where you’re going and what exit to take well in advance. Deceleration lanes aren’t necessarily necessary, but early signage helps out-of-towners a ton.
Some sections of the U.S. Interstate system would be fine at 200+ kmph. Others are too rough and cracked for even 100 kmph. And the U.S. system – at least as far as road maintenance goes – is really 50 separate systems. Some places are maintained very well … other places, not so much.
Were Hellcats equipt with a automatic setting that makes it sound more "muscle car"ish? I know some cars were and if so I think you may be right.
I’m trying to think of a car that would need any less help in sounding like a muscle car than a Hellcat. Unless Bear_Nenno bought the ‘Gilding the Lily’ option.
I agree with Joey on the torque converter being the issue. The wrong trans fluid can cause this. I doubt on a new car such as your that it would have the wrong fluid but if all else fails maybe request that they change it on warranty.
You have an expensive performance car under factory warranty, take advantage of it. Tell the dealer it isn’t acceptable for a top-of-the-line Hellcat to have an issue like that, and it’s a safety issue if it starts shaking like a blown tire at high speeds.
If you had warning lights there should be codes to read from the ECU, if the codes don’t reveal the exact problem they should at least provide a clue.
This is a $60,000+ car, tell them if you’re ever buying a Chrysler vehicle again they need to make it right. Stay on the dealer, make friends with the service manager and/or mechanics and keep gently pushing until it’s fixed. Or if the dealer doesn’t seem willing/able, go to another dealer or call corporate.
I’m a fan of going fast where legal, but when you have a known issue that might involve anything from brakes to wheel bearings, I’d take it slow. A locked wheel or loss of brake power can be dealt with at 60 mph. At 190 mph… not so much.
Be safe in a car that isn’t working at 100%.
I dunno, car would cruise comfortable at 150mph+ all day long if it was legal. Speed limits haven’t kept up with technology. Driving at 60mph seems super slow.
Not when you have an undiagnosed problem with your car that manifests itself as potential problems with shimmy, braking, etc. What if it’s an early warning of a major failure? Do you want to experience that at 150 mph?
Incidentally, how many Dodge dealerships are there in Germany? Who works on or even looks at this car over there?
