What stands out
Of the 10 model years of Acura MDX we track for cruise control problems, this one carries the most owner complaints on file — 11.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering cruise control on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2018 Acura MDX shows a pattern of acceleration and throttle-control failures across 11 complaints. The most common complaint is a 1–3 second delay between pressing the gas pedal and the vehicle responding, especially from complete stops or at low speeds. After that delay, the car lurches hard rather than accelerating smoothly. Owners describe this as frequent and intermittent but reproducible, and more pronounced when the engine is cold. It creates real danger during left turns across traffic and freeway merges.
A second group reports sudden complete loss of throttle response at highway speeds (70–85 mph), where the car simply won't accelerate for 1–2 seconds, forcing the driver to lift off and re-press the pedal. One owner also reported unintended cruise control engagement from a complete standstill when the resume button was bumped—the dealership confirmed this happens but called it normal.
One owner's hesitation and loss-of-power issues resolved after the dealership performed a fuel pump recall repair, and the same owner's service tech later admitted the dealership should have caught that earlier. Most other owners report dealerships dismissing the issue as normal, applying software updates without effect, or refusing to acknowledge the problem despite test-driving it. One owner describes automatic emergency braking engaging incorrectly and the transmission locking up momentarily. Dealerships have offered no recalls or TSBs to address these complaints despite years of reports.

Failure modes owners describe
Throttle delay and hesitation from stops
Significant delay (1–3 seconds) between pedal press and engine response, particularly at low speed or from complete stops. Vehicle then lurches or accelerates suddenly at the rate of current pedal position rather than ramping smoothly. Intermittent but reproducible; worse when engine is cold. Affects safety during merges, left turns across traffic, and emergency maneuvers.
When: From 2020 onward in complaint #1 (2-year ownership); ongoing since purchase in complaints #4, #7, #9, #10
Symptoms owners cite: 1–3 second delay between gas pedal press and vehicle response; Sudden hard acceleration after delay rather than gradual ramp; More frequent when engine is cold; Intermittent but reproducible, especially from stops; No warning lights or error codes reported by dealer
Repairs/costs cited: Complaint #4 states dealership performed transmission software update with no effect. Complaint #1 resolved after fuel pump recall repair (2024). Complaint #9 notes software updates applied without resolution.
Recalls/TSBs owners mention: Complaint #1: Acura notified owner of fuel pump recall; repair resolved the hesitation issue. Complaints #4, #7: Dealerships claimed issue is 'normal' or 'normal Acura trait.' Complaint #7 notes Honda does not see it as a problem. Complaint #9: all available software updates applied without fix.
Unexpected cruise control engagement from standstill
Cruise control resume button engages vehicle from complete standstill or very low crawl speed (4–5 mph) even when no speed was previously set. Car launches forward unintentionally when resume button is accidentally bumped. Dealership technician confirmed reproducibility but claimed this is a normal Acura characteristic.
When: Discovered after dealer service in complaint #2; timing not specified in other complaints
Symptoms owners cite: Cruise resume button causes car to launch forward from complete stop; Engages at virtual 4–5 mph crawl from standstill; No prior speed set since engine start, yet resume still activates acceleration; Accelerates to 25–30 mph unintentionally when bumped
Repairs/costs cited: No repair attempted. Complaint #2 dealership suggested disabling cruise master control before each start as a workaround.
Recalls/TSBs owners mention: Complaint #2 dealership claimed this is a normal Acura trait; service writer said other manufacturers (e.g., Subaru) exhibit the same behavior and that customers frequently complain but it is considered acceptable.
Loss of acceleration response at highway speeds
Complete loss of throttle response for 1–2 seconds during high-speed driving (70–85 mph). Driver must lift off pedal and re-press to regain power. Occurs intermittently but consistently during high-speed acceleration maneuvers, presenting acute safety risk during merging and passing.
When: At least 3 times over past year in complaint #3; complaint #5 occurred at 60 mph with approximately 50,000 mileage
Symptoms owners cite: Sudden complete loss of acceleration response at freeway speeds (70–85 mph); Vehicle stops responding to throttle input for 1–2 seconds; Must lift foot off pedal and re-press to regain power; Intermittent but consistently during high-speed acceleration; No warning lights
Repairs/costs cited: Complaint #5: Vehicle repaired under unknown fuel pump recall; failure persisted. Dealership contacted two more times; vehicle not repaired.
Recalls/TSBs owners mention: Complaint #3: dealership claims cannot replicate problem and does not consider it a concern; no resolution offered. Complaint #5: manufacturer made aware and provided case number, but repair did not resolve issue.
Automatic emergency braking malfunction and transmission lockup
Automatic brakes engage without reason while driving downhill, causing complete stop. Vehicle becomes stuck in gear and will not move when trying to accelerate, as if transmission is frozen. Brakes eventually release. Second activation occurs shortly after on same downhill section with no vehicle ahead. Almost caused rear-end collisions.
When: Complaint #6 describes two incidents while driving downhill on same route; timing not specified
Symptoms owners cite: Automatic brakes engage while driving downhill on clear road; Vehicle comes to complete stop; Transmission stuck in gear; vehicle will not move when accelerating; Behaves like manual transmission not shifted for extended period; Brakes eventually release; Second occurrence shortly after on same downhill route with no vehicle ahead
Repairs/costs cited: No repair mentioned; complaint describes ongoing safety risk.
Engine stalling and jerky transmission behavior
Engine stalls; acceleration is difficult with jerky transmission response. Owner expresses concern about highway safety and inability to control vehicle properly. Minimal diagnostic detail provided.
When: Ongoing; owner commutes daily on highway
Symptoms owners cite: Engine keeps stalling; Problem accelerating; Jerky transmission

The engien keep stalling, prolem accelerating jurky transmisión and this is the only car I have to go work I take the highway everyday I am cosern that something can happend to me.
When trying to accelerate from a stop the car has a noticeable lag in throttle response. 2+ seconds. This does not always happen but is intermittent. Much more often when the engine is colder. This makes a left turn in front of traffic or any move where you need to merge with traffic go from safe to dangerous, this also confuses other drivers as they wonder why you are not moving.
