Some 345 examples of the 2023 Challenger SRT Demon 170 are covered by a new Dodge customer service notice. The trouble sits at the front of the supercharged V8. There, a Demon 170 crankshaft damper and its bolt can work loose. Rather than have owners drive in, Dodge wants these cars hauled to the dealer on a truck.

That last instruction is unusual, and it tells you how seriously the company takes the problem. This is not a safety recall. Instead, it is a service action aimed at a small batch of cars built with parts from one supplier production period. Even so, the stakes are high for an engine this expensive.

Dodge built the Demon 170 in limited numbers, so a batch of 345 cars is a meaningful share of the run. Here is what the notice covers, what can go wrong, and what owners should do next.

What the Demon 170 crankshaft damper notice covers

According to Mopar Insiders, which reported the notice on September 14, 2026, it applies to 345 specific 2023 Demon 170 VINs. The outlet puts total Demon 170 production at about 3,300 cars. In other words, roughly one in ten Demon 170s is on the list.

Mopar Insiders also reports that Dodge traced the issue to one supplier production period. It affects the damper and its related bolt. That’s why the notice covers only a slice of the run instead of every car. The outlet adds that Dodge acted after “some failures in the field.”

Later, autoevolution reported the same figure of 345 cars for the U.S. market. It also gave Dodge’s internal code for the action as C6C. Both outlets stress the same point: this is a service notice, and Dodge did not classify it as a safety recall.

What a crankshaft damper does

A crankshaft damper, often called a harmonic balancer, bolts to the nose of the crankshaft. Its job is to soak up twisting vibrations as the crank spins. If it comes loose, the damper can no longer do that job, and it can start to move around.

For the Demon 170, autoevolution says the fasteners from certain supplier batches may loosen over time. Once that happens, a loose damper will damage the front timing chain cover. The first warning sign, according to both reports, is an abnormal noise from the engine compartment.

Mopar Insiders goes further. It quotes Dodge CEO Matt McAlear as warning that continued operation could result in “catastrophic engine damage.” Carscoops also reports that the company has “received reports of several engine failures.” That explains the push to keep these cars off the road until the fix is done.

Why Dodge wants the cars towed

Mopar Insiders reports that Dodge “strongly recommends that owners have their Demon 170 transported to the dealership rather than driving it in for the repair.” Dodge also covers the cost of that transport, both to the dealer and back home. For an owner, that means no miles and no risk on the trip in.

Autoevolution adds the specific limits. It reports reimbursement of up to $250 for towing from the owner’s location and up to $250 for the return trip. Claims above $250 need corporate review and approval. The outlet also says each owner gets a letter by mail. Dodge then assigns a customer assistance advocate to set up the appointment and the transport.

The repair itself is straightforward. Autoevolution reports that dealers install a new crankshaft damper and a new hex flange head bolt. It lists the Mopar part numbers as CCAPC6C1AA for the damper and CCAPC6C2AA for the bolt. Before any work starts, the 6.2-liter engine must cool to ambient temperature, the outlet says.

Mopar Insiders notes one more detail that will reassure owners. “The front fascia does not have to be removed to complete the work,” it reports. Technicians can do the job from underneath the car.

How owners can check their car

Owners can run their VIN on Mopar’s website, according to both outlets. However, there is a catch. This is a customer service notice, not a recall. As a result, Mopar Insiders says the car shows up under the CSN section, not the recall section. An owner who checks only for recalls could miss it.

Anyone who hears a new noise from the front of the engine should stop driving the car and call a dealer. That advice comes straight from the symptom both outlets describe. Meanwhile, the mailed letter and the assigned advocate should handle the scheduling for owners on the list.

The car behind the notice

Autoevolution calls the Demon 170 the most powerful series-production Challenger, which is why a front-of-engine fault draws so much attention. According to Stellantis’ own launch release, its 6.2-liter supercharged HEMI V-8 makes 1,025 horsepower and 945 lb-ft of torque on E85. On E10 pump gas, Dodge rated it at 900 horsepower and 810 lb-ft.

The same release lists an NHRA-certified quarter-mile of 8.91 seconds at 151.17 mph. It also claims a 0-60 mph time of 1.66 seconds. At launch, Dodge set the price at $96,666 before destination, and ordering opened on March 27, 2023.

Finally, Stellantis capped production at 3,300 cars: 3,000 for the U.S. and 300 for Canada. With 345 cars on this notice, owners of the other Demon 170s are not part of the action. For the owners who are, the fix is a new damper and bolt. Autoevolution reports Dodge will cover up to $250 of towing each way.
