2018 Dodge Challenger: Buy or Avoid?

The 2018 Dodge Challenger offers undeniable classic muscle appeal with a surprisingly comfortable ride, but its formidable V8 powertrains carry specific risks that demand careful consideration. While V6 models are largely robust, the HEMI engines are prone to costly lifter and camshaft wear if maintenance is overlooked, making a pre-purchase inspection crucial. Expect a fun, engaging drive, but budget for potential electrical fixes and diligent V8 maintenance.

While the 2018 Dodge Challenger delivers an unparalleled muscle car experience and the V6 models are highly dependable, the known issues with the HEMI V8 engines mean prospective buyers must exercise caution. A thorough pre-purchase inspection is non-negotiable for V8 variants to avoid potentially catastrophic and e…

2018 Dodge Challenger — Known Trouble Spots

The systems that tend to fail first on the 2018 Dodge Challenger, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.

1
HEMI V8 Valvetrain Issuesmajor~80,000-150,000 mi

The 5.7L, 6.4L, and 6.2L Supercharged HEMI V8 engines are susceptible to lifter and camshaft wear, often manifesting as a 'HEMI tick.' This can lead to reduced performance and, if neglected, catastrophic engine damage.

2
Uconnect Infotainment Systemminor~All mileages mi

Owners frequently report the Uconnect 8.4-inch system freezing, rebooting spontaneously, experiencing Bluetooth connectivity issues, or touch screen unresponsiveness. While often resolvable with software updates, module replacement can b…

3
Electrical Systemmoderate~40,000-80,000 mi

Beyond Uconnect, some Challengers experience parasitic battery drains, often attributed to various modules not powering down correctly. This can lead to dead batteries, particularly after the vehicle has sat for a few days.

Full repair-cost ranges, fix-before-you-buy notes, and inspection checklists are in the report.

2018 Dodge Challenger Mileage Danger Zones

The mileage windows when the 2018 Dodge Challenger most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

30,000

Low Risk Zone

At this mileage, the Challenger is still relatively new. Focus on routine fluid changes and tire rotations. Keep an eye out for early Uconnect glitches or any unusual noises from the suspension.

60,000

Maintenance Zone

This mileage often calls for more comprehensive maintenance, including spark plug replacement (especially on V8s), transmission fluid check/change, and thorough brake system inspection. Suspension components may start showing early signs…

90,000

Elevated Risk Zone

For HEMI V8 models, this is where the risk of lifter and camshaft wear significantly increases. Be vigilant for any 'tick' or abnormal engine noise. Other common items include universal joints, drive belts, and potential electrical greml…

120,000+

High Risk Zone

Beyond 120,000 miles, major component wear is more likely across the board. The likelihood of significant engine or transmission repairs increases, especially if prior maintenance was neglected. Budget accordingly for potential higher-co…

2018 Dodge Challenger Ownership Cost Outlook

Annual Maintenance

$400-700 (V6), $600-1,000+ (V8)

Moderate Repairs

$500-1,500 occasionally (e.g., suspension work, electrical diagnosis)

Safety Recalls on the 2018 Dodge Challenger

4 recalls on record from NHTSA. Check your VIN atnhtsa.gov to see if the repair was performed.

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)
