We pulled 44,350 owner complaints filed with the U.S. government’s NHTSA database across ten Dodge models and counted how many specifically mention the check engine light. About 1 in 18 (5.4%) do. The Dodge Dart leads at 8.6% — nearly triple the Dakota’s 3.0% — and its complaints skew toward the powertrain, matching the Dart’s well-known transmission reputation. Below is the full ranking, the systems owners complain about most by model, and the specific OBD2 codes behind those check engine lights, with a fix guide for each.
How We Counted This
The data comes from the NHTSA Office of Defects Investigation (ODI) consumer complaint database, the free public record every U.S. driver can file to. We pulled every complaint for each model across its production years (2007–2024) on June 14, 2026, then counted the complaints whose text mentions the check engine light — matching “check engine,” “engine light,” “CEL,” “malfunction indicator,” or “MIL.” The mention rate (share of a model’s complaints that name the light) is the fair way to compare models, because raw complaint counts also reflect how many were sold and how old the model is. Two honest caveats: a text mention is a proxy, not an official code tally, and small samples (the Dakota’s 332 complaints) are noisier than large ones (the Ram’s 13,745). Source: NHTSA.gov.

Counts are the number of complaints naming each NHTSA component category; a single complaint can name more than one. “Mention CEL” is the count of complaints whose text references the check engine light.
What the Numbers Actually Show
- The Dart is the standout. At 8.6% it has by far the highest check-engine-mention rate, and its #1 complaint category is the power train — consistent with the Dart’s troubled dual-dry-clutch automatic and 2.4L Tigershark engine. For a short-lived model, that’s a loud signal.
- The Ram 1500 dominates by volume, not rate. Its 826 check-engine mentions are the most of any model simply because it sold in huge numbers over 15 years; its 6.0% rate is mid-pack. Its top complaint is actually steering (the well-known “death wobble”), with engine close behind.
- Electrical leads almost everywhere. On eight of ten models the most-complained system is the electrical system — a reminder that on modern Dodges a check engine light often traces back to sensors, grounds, and a weak battery before any mechanical part. That’s why a U0100 communication code so often starts with battery and wiring checks.
- The muscle cars complain least about the engine light. The Challenger (3.8%) and Charger (5.0%) sit low, and a big share of their complaints are air bags and electronics rather than the engine — these are newer platforms with fewer emissions-era miles on them.
The Codes Behind Those Check Engine Lights, by Model
NHTSA tracks broad systems, not OBD2 codes. Here is the layer underneath — the specific codes each model is known for, drawn from our diagnostic library. Each links to a cheapest-cause-first fix guide; start at your model’s full guide.

FAQ: Dodge Check Engine Light by Model
Which Dodge model has the most check engine light complaints?
It depends on whether you mean rate or raw volume. By rate, the Dodge Dart leads: 8.6% of its NHTSA complaints mention the check engine light, nearly triple the Dakota’s 3.0%. By raw volume, the Ram 1500 has the most, with 826 check-engine mentions across 13,745 complaints, simply because it sold in far greater numbers over more years. The mention rate is the fairer comparison between models.
Where does this Dodge check engine light data come from?
From the NHTSA Office of Defects Investigation consumer complaint database, the free public record U.S. drivers file to. We pulled every complaint for ten Dodge models across their 2007 to 2024 production years on June 14, 2026, then counted the complaints whose text mentions the check engine light, engine light, CEL, malfunction indicator, or MIL. The full per-model figures are reported in the table above.
Does a high complaint count mean a Dodge model is unreliable?
Not on its own. Raw complaint counts reflect how many vehicles were sold and how long the model has been on the road, not just how often it breaks. That is why we report the mention rate, which normalizes for volume to some degree. Even so, treat the numbers as directional rather than a precise reliability score, and remember that small samples like the Dakota’s are noisier than large ones.
What are the most common check engine codes on a Dodge?
Across the lineup the codes cluster on a short list: misfires (P0300 and P0301 through P0308), catalyst efficiency (P0420 and P0430), EVAP leaks usually starting at the gas cap (P0456, P0455), and a slow-warming thermostat (P0128). Pentastar V6 models such as the Charger, Durango, and Challenger add the P06DD oil-control code. Read the actual code before buying parts.
How do I find out what is causing my Dodge check engine light?
Plug a basic OBD2 scanner into the port under the dash and read the stored code, then look that code up before replacing anything. On older Dodges the key-dance trick can flash two-digit codes on the dash, but a scanner gives the exact OBD2 code. From there, start at your model’s full check engine light guide and work the cheapest likely cause first.
