The 2023 Dodge Challenger SRT Demon 170 marked the end of Dodge’s HEMI-powered era, delivering 1,025 horsepower and 945 lb-ft of torque from a supercharged 6.2-liter HEMI V8 when running on E85. Now, Dodge is issuing a Customer Service Notice for 345 of these cars over a potential issue involving the engine’s crankshaft damper assembly.
345 Demon 170s Are Affected
Dodge built only about 3,300 Challenger SRT Demon 170s before ending the Challenger’s V8 chapter. The new Customer Service Notice, or CSN, covers 345 specific 2023 Demon 170s, representing about 10% of total production.
The notice is not an official recall. However, Dodge wants affected owners to have the issue addressed promptly after identifying a potential problem with the crankshaft damper assembly.
What Dodge Found
Dodge CEO Matt McAlear disclosed details about the CSN to MoparInsiders. The issue involves the crankshaft damper and its retaining bolt, which came from a particular batch supplied by one supplier.
Dodge reviewed its production records to identify the vehicles that received the potentially affected parts. The cars are not arranged in a straightforward VIN sequence, so owners cannot simply determine whether their vehicle is affected by checking its build number.
Dodge has identified the specific vehicles involved and is contacting their owners directly. The investigation began after field failures were reported, with engineers tracing the problem to a specific supplier batch and narrowing the affected group to 345 cars.
Dodge warns that owners should pay attention if their Demon 170 develops unusual noises from under the hood. Continuing to drive despite the symptoms could lead to additional engine problems, with Dodge officials warning that the worst-case scenario could involve catastrophic engine damage.
What Demon 170 Owners Should Do
Dodge is taking additional precautions for vehicles included in the Customer Service Notice. Owners of affected Demon 170s should not drive their cars to the dealership. Instead, Dodge will arrange transportation to an authorized shop and return the vehicle after the repair.
The repair itself is expected to take about two hours, although the overall process could take longer depending on the dealer’s schedule. Technicians can perform the work from underneath the vehicle without removing parts from the front.
How to Check Your Demon 170
Owners can determine whether their vehicle is affected by entering its VIN into Mopar’s online lookup tool and checking the Customer Service Notices section rather than the recall section, because this action is not an official recall.
If no notice appears, the vehicle is not affected. With only 345 of about 3,300 Demon 170s included in the notice, most owners do not need to take action.
For owners of the affected 2023 Dodge Challenger SRT Demon 170s, however, Dodge recommends addressing the issue promptly rather than continuing to drive the vehicle.
