Used 2017 Dodge Charger Problems — Is It Worth Buying?
The 2017 Charger is one of the last true American rear-wheel-drive performance sedans. It's fast, spacious, and distinctive — and it carries some specific problems you need to know before you buy.
2017 Dodge Charger Overview
The seventh-generation Charger (2011–2023) offers engine choices from the 3.6L Pentastar V6 (292 hp) through the 5.7L HEMI V8 (370 hp), and up to the SRT 6.4L 392 (485 hp). RWD is standard; AWD (All-Wheel Drive) is available on V6 models. Used prices range $15,000–$30,000 depending significantly on engine, trim, and whether it was used as a fleet or police vehicle (a common fate for Chargers — avoid ex-fleet examples).
Common Problems to Watch
- Hemi tick (5.7L): The 5.7L HEMI has a well-documented "Hemi tick" — a tapping sound that appears on cold start or at idle. Some cases are benign (MDS solenoid noise); others indicate lifter or rocker arm wear. Have a mechanic diagnose the specific tick before buying.
- MDS (cylinder deactivation) lifters: Like the Silverado's AFM, the HEMI's Multi-Displacement System can cause lifter failure. An MDS delete ($800–$1,200) is a common proactive fix.
- 8HP automatic transmission fluid: The ZF 8-speed transmission requires OEM fluid — non-OEM fluid can cause shuddering. Verify the transmission service history uses the correct fluid specification.
- Fuel economy (HEMI): The 5.7L HEMI averages 15–18 mpg in real-world driving. This is a significant ongoing cost — factor fuel costs into your total ownership calculation.
- Police package ex-fleet vehicles: Many Chargers served as police cruisers and unmarked police cars. These are driven hard — verify the vehicle history carefully and avoid dealer auctions with unclear history.
What to Inspect
Cold-start the engine and listen specifically for the Hemi tick. If present, have a mechanic determine if it's benign or mechanical wear. Check the transmission fluid color and smell. Inspect the brakes — Chargers are hard on brakes due to weight and performance use. Check tire wear for even distribution (uneven wear can indicate alignment or suspension issues from spirited driving). Pull a full vehicle history report and confirm no fleet or ex-police history.
Reliability Verdict
The 2017 Charger is a capable, characterful car with average reliability for its class. The 3.6L V6 is simpler and avoids MDS concerns. The 5.7L HEMI is the iconic choice but requires MDS scrutiny. If you find a clean private-owner car with documented maintenance and no Hemi tick, it's a solid buy for enthusiasts who factor in the fuel and performance tire costs.
FAQ: 2017 Dodge Charger
It can be. Some ticks are benign MDS solenoid noise; others indicate failing lifters that can lead to catastrophic engine damage. Never buy a ticking Hemi without a mechanic's diagnosis.
Run the VIN through Carfax and AutoCheck. Police trim packages also have telltale signs: partition mounts, extra wiring harnesses, and wear patterns. Avoid if uncertain.
V6 for reliability and fuel economy. HEMI for the experience. The V6 is genuinely quick and skips the MDS lifter concern entirely. The HEMI requires more scrutiny but delivers a very different driving experience.
