2020 Acura MDX Common Problems by Component
188 owner complaints grouped by vehicle system.
ENGINE
38 complaintsOwners of the 2020 Acura MDX frequently report issues with the engine, particularly related to unexpected engine shutdowns and problems with the Auto Idle Stop feature. Common symptoms include the engine stalling or failing to restart after being stopped at traffic lights, with the vehicle often shifting to neutral and requiring a manual restart. Several complaints also mention connecting rod bearing failures, sometimes leading to complete engine replacements. These issues are often reported at mileages ranging from 10,000 to over 100,000 miles. Safety implications are notable, as sudden engine failures during driving or braking can lead to potential collisions, and the inability to restart promptly in traffic poses a risk. This information may be particularly relevant for used car buyers evaluating the reliability and safety of this model.
ELECTRICAL SYSTEM
31 complaintsSafety-relatedOwners report frequent issues with the Auto Engine Idle Stop system in the 2020 Acura MDX, where the vehicle fails to restart after coming to a stop, often shifting into neutral or shutting down completely. This problem is commonly described in stop-and-go traffic or at stoplights, with symptoms including the vehicle stalling and requiring manual restarting, sometimes accompanied by illuminated warning lights. Complaints often arise at mileages ranging from 10,000 to 44,000 miles. Safety implications are noted, as the vehicle's unexpected shutdowns occur in active traffic, posing risks of rear-end collisions. Additionally, some owners mention problems with electrical system components like the alternator and emissions lights, though these are less frequently reported than the start/stop issue.
POWER TRAIN
17 complaintsOwners report frequent issues with the 2020 Acura MDX power train, particularly with the vehicle unexpectedly shifting into neutral. This occurs often during stops or when the auto-start/stop feature engages, with multiple owners describing the need to restart the vehicle to resume driving. Symptoms include the vehicle stalling, hesitating to accelerate, and unintended gear shifts, often without warning lights. These issues typically arise around 20,000 to 50,000 miles, and some owners note incidents on highways, posing safety risks such as near rear-end collisions. Additionally, some complaints mention sudden acceleration and engine noise, indicating possible broader transmission or engine concerns.
FORWARD COLLISION AVOIDANCE (16 complaints)
FORWARD COLLISION AVOIDANCE
16 complaintsOwners of the 2020 Acura MDX frequently report failures of the multipurpose front camera, which impacts several Advanced Driver-Assistance Systems (ADAS) such as Lane Keeping Assist, Adaptive Cruise Control, and Collision Mitigation Braking. Common symptoms include simultaneous warning messages on the dashboard and the sudden loss of these safety features, often requiring costly camera replacements. Complaints typically arise between 25,000 and 50,000 miles, with some reports indicating that the camera overheats. Safety implications are significant, as the sudden deactivation of critical systems could increase collision risk, and at least one report describes injuries linked to improper engagement of the Collision Mitigation System. This information is crucial for used car buyers considering the 2020 Acura MDX, as it highlights potential repair costs and safety concerns.
ENGINE AND ENGINE COOLING (13 complaints)
ENGINE AND ENGINE COOLING
13 complaintsOwners of the 2020 Acura MDX frequently report issues related to stalling and hesitation while driving, with some stating that the vehicle loses motive power without warning. Complaints often mention that the vehicle hesitates to start and in some cases, stalls at various speeds or while idling. These issues appear to occur at mileages ranging from approximately 25,000 to 65,000 miles. Several owners express frustration with the unavailability of parts for recall repairs, which they believe has taken an unreasonable amount of time. No reports indicate crashes, fires, or loss of control due to these issues, but the stalling and hesitation could pose safety concerns if they occur in traffic.
VEHICLE SPEED CONTROL (8 complaints)
VEHICLE SPEED CONTROL
8 complaintsOwners of the 2020 Acura MDX report issues with vehicle speed control, particularly unexpected acceleration and deceleration. Complaints frequently mention the vehicle accelerating on its own, sometimes described as "hiccups," and abrupt braking when adaptive cruise control is engaged, even when no vehicles are nearby. Multiple owners describe these issues occurring at both low and high speeds, with some incidents leading to near-collisions due to sudden power loss or unexpected braking. Typical symptoms also include the vehicle unexpectedly shifting into neutral and requiring a restart to resume normal function. These issues are reported across a range of mileages, with some vehicles having as few as 1,500 miles, suggesting potential concerns for both new and used car buyers.
SERVICE BRAKES (6 complaints)
SERVICE BRAKES
6 complaintsOwners of the 2020 Acura MDX frequently report issues with the vehicle's idle stop function, which often fails to restart the engine when the brake pedal is released. This problem can leave the vehicle inoperable at traffic signals or intersections, posing a potential safety risk. Several complaints also mention the automatic emergency braking system activating without cause, sometimes while accelerating, which could lead to near-collision scenarios. Additionally, one owner notes an issue with the electric parking brake not disengaging. These problems are observed at various mileages, with one report specifically mentioning an occurrence at 6,000 miles. Buyers should be aware of these potential safety implications when considering a used 2020 Acura MDX.
AIR BAGS (4 complaints)
AIR BAGS

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
