Is the 2018 Dodge Challenger a reliable car?
Overall, the 2018 Dodge Challenger is generally considered to have average reliability for its class; it isn’t seen as exceptionally dependable, but with regular maintenance many owners report solid long-term durability. The base V6 model tends to offer the most straightforward ownership experience, while the high-performance variants add complexity and higher maintenance costs.
The question of reliability for the 2018 Challenger depends on the chosen powertrain, how the car has been cared for, and how it was driven over time. Built on an older platform with a long production run and multiple updates, reliability can vary significantly between trims. Independent reviews and owner feedback typically rate it in the middle of the pack among sporty coupes and muscle cars, with better results for well-maintained non-performance versions and more variable outcomes for turbocharged or supercharged variants.
Reliability signals from major sources
The following notes summarize what leading automotive reliability sources and recall data say about the 2018 Challenger.
- Consumer Reports and J.D. Power generally place the Challenger in the middle of the pack for reliability, with variation by trim and how the vehicle is used.
- Owner surveys and service histories show a mix of solid long-term durability and some recurrent issues, particularly on higher-performance models when mileage increases.
- Recalls and service campaigns have affected various Challenger models in the 2015–2018 window; checking the VIN for open recalls is advisable before purchase or ownership.
Conclusion: Reliability signals point to an average-risk profile overall, with more maintenance and higher potential costs on performance-oriented versions.
Common issues reported by owners
Owners and service reports highlight a few recurring themes, though frequency varies by engine choice and care. These insights help frame what to watch for in maintenance and ownership costs.
- Electrical and infotainment glitches, including occasional Uconnect freezes or Bluetooth connectivity problems.
- Transmission behavior such as occasional hard shifts or shudder in some 8-speed automatics, often mitigated by software or updated calibration.
- Cooling system concerns on some V8 models, including wear around hoses or radiators that can lead to higher cooling demands in hot conditions.
- Oil consumption or exhaust-related concerns on certain high-performance engines, particularly in higher-mileage or heavily driven variants.
Note: Many issues are addressable under warranty or via service advisories; individual experiences depend on maintenance history and driving patterns.
Engine and variant reliability
Reliability in the Challenger lineup varies by powertrain. The V6 is typically the simplest and most economical to maintain, while the V8 Hemi options add complexity and potential maintenance costs. The high-performance Hellcat and other supercharged variants demand extra care due to their elevated heat and load.
- V6 models: generally the most straightforward and potentially the most reliable option in the lineup, with lower routine maintenance costs.
- Standard V8 Hemi models: more power and complexity; reliability remains strong when serviced on schedule, but maintenance costs rise with age and mileage.
- Hellcat and other high-performance variants: outstanding performance but higher ongoing maintenance costs and a greater likelihood of wear in cooling, supercharger, and lubrication systems; regular, proactive servicing is essential.
Conclusion: If reliability and lower ownership costs are priorities, a well-maintained V6 Challenger is typically the strongest choice; if you want peak performance, be prepared for higher maintenance and repair needs.
Buying a used 2018 Challenger: what to check
Shopping for a used Challenger requires careful due diligence to avoid hidden issues and future repair costs. Verifying history, maintenance, and recall status is especially important for a model with a broad range of trims and powertrains.
- Maintenance records: confirm regular oil changes with the recommended oil type and interval; verify cooling system maintenance and any belt/tensioner work.
- Recall history: use the VIN to check for open or completed recalls and ensure campaigns have been addressed.
- Drivetrain evaluation: test-drive for smooth shifts, throttle response, and any transmission or drivetrain noises; consider a professional scan for fault codes.
- High-performance variant checks: inspect the supercharger drive, intercooler, cooling system, exhaust components, suspension bushings, and tires for signs of heavy use or overheating wear.
Bottom line: A thorough pre-purchase inspection (PPI) is particularly valuable for a 2018 Challenger, given the range of engines and performance equipment and the potential cost of repairs later on.
Summary
The 2018 Dodge Challenger offers a compelling blend of performance and style, but its reliability is mixed rather than exceptional. Base and mid-range trims with the V6 generally present the strongest reliability profile and lower ownership costs, while high-performance variants—especially those with forced induction—offer spectacular speed at the expense of higher maintenance needs and potential issues as miles accumulate. Prospective buyers or owners should prioritize a complete service and recall history, consider a professional pre-purchase inspection for used models, and be prepared for higher maintenance expenses on the performance-focused versions. With attentive upkeep, a well-maintained 2018 Challenger can be a durable, engaging sports car for many years.
