On the 2016-2020 Acura MDX 3.5L J35Y5 V6, third-generation MDX models with the ZF 9-speed automatic suffer from torque converter shudder during light throttle acceleration between 30-50 mph. The lockup clutch in the torque converter vibrates as it engages, creating a sensation similar to driving over rumble strips that many owners mistake for an engine misfire.

This issue also affects: Acura CL, Acura ILX, Acura TL

Common Symptoms

  • Vibration/shudder at 30-50 mph under light throttle
  • Sensation like driving over rumble strips
  • Shudder disappears under hard acceleration
  • Vibration felt through seat and steering wheel
  • Transmission slipping sensation

How to Fix

Update the TCM software to the latest Acura calibration that modifies torque converter lockup strategy. Perform a complete ATF drain and refill with Honda DW-1. If shudder persists after software update and fluid change, the torque converter assembly must be replaced.

Owner tips & cautions

  • TipGet the TCM update first — it resolves about 70% of cases for free under warranty. If the shudder returns after 10,000 miles, the torque converter needs replacement. Do not let the dealer just change fluid and send you home.
Typical repair cost:$200 - $3,200

On the 2016-2019 Acura MDX, the ZF 9HP 9-speed automatic introduced on the 2016 MDX suffers from documented hesitation, harsh shifts, lurching, and unexpected downshifts/deceleration. Drivers report the vehicle hesitating from a stop, banging into gear, or briefly losing power. Software miscommunication between TCM, ECM and throttle control is the alleged root cause; a class action was filed alleging Honda knew of the defect from 2015.

This issue also affects: Acura CL, Acura TL, Honda Passport

Common Symptoms

  • Hesitation from a stop
  • Hard or banging shifts
  • Unexpected downshift while cruising
  • Brief loss of power
  • Lurching at low speed

How to Fix

Have dealer apply latest TCM/PGM-FI software updates first (covered by powertrain warranty). If symptoms persist, request fluid replacement and dealer escalation; document everything for lemon-law/class-action relief. Avoid jerky throttle inputs while cold.

Typical repair cost:$0 - $6,500

On the 2016-2020 Acura MDX J35Y5, on 2016-2020 Acura MDX with the 3.5L V6 (J35Y5) and Auto Idle-Stop, the engine may fail to automatically restart from a stop event, leaving the driver stranded in traffic. NHTSA opened an Engineering Analysis (PE22-016 → EA) after 1,300+ complaints across ~2.2M Honda/Acura vehicles, with 4 confirmed accidents. Acura issued Service Bulletin 23-001 in January 2023 with a PGM-FI software update (reduces idle-stop operating range) and extended warranty coverage on starter replacement and valve adjustment to 10 years / unlimited miles. Note: the Sport Hybrid (J30Y1) uses a different motor-based stop/start system and is not in scope of this TSB.

Common Symptoms

  • Engine does not restart after auto-stop event
  • Have to press Start button or shift to Park to restart
  • Warning chime / MIL
  • Battery drain after repeated failures

How to Fix

Have dealer perform the PGM-FI idle-stop software update plus starter / starter relay inspection per Honda's 2023 service campaign (covered 10 years). To avoid recurrence, defeat Idle-Stop with the dash button each drive or install an aftermarket auto-disable module.

Typical repair cost:$0 - $1,500

On the 2014-2020 Acura MDX 3.5L J35Y5 V6, the AcuraLink infotainment system in third-gen MDX models experiences random reboots during driving, temporarily disabling navigation, audio, and the backup camera. The system takes 30-60 seconds to restart, leaving the driver without audio or navigation guidance mid-route.

This issue also affects: Acura RDX, Acura TLX

Common Symptoms

  • Screen goes black and reboots while driving
  • Audio cuts out for 30-60 seconds
  • Navigation loses route mid-trip
  • Backup camera unavailable after reboot
  • Bluetooth disconnects and fails to reconnect

How to Fix

Update to the latest infotainment firmware from an Acura dealer. Reset the system to factory defaults and clear cached data. If reboots continue, the infotainment control module may need hardware replacement under an extended warranty program.

Owner tips & cautions

  • TipAsk the dealer specifically for the latest firmware version — many dealers install outdated updates. The 2019 firmware revision dramatically reduced reboot frequency for most owners.

On the 2014-2016 Acura MDX, the third-gen MDX's stacked dual-display infotainment (8" upper + 7" touch) on 2014-2016 models suffers from slow boot times, screen freezes, Bluetooth dropouts, and random reboots. Acura issued TSB 15-001 (software v3.00.2304, dated 08/21/2015) for 2014 MDX, replacing TSB 14-014, to address speed and bug issues. TSB B15-036 covers 2014-2015 for HVAC display flicker. 2016 received a separate software track via AcuraLink updates. 2018 added Apple CarPlay, which introduced separate iOS-update compatibility issues.

Common Symptoms

  • Lower touchscreen frozen / unresponsive
  • Slow boot (30+ seconds)
  • Random reboots while driving
  • Bluetooth audio dropouts
  • Backup camera lag or stuck-on display

How to Fix

Have dealer install latest infotainment software update (TSB 15-001 v3.00.2304 for 2014; later versions for 2015-2016 via update disc/AcuraLink). Perform a soft reset by holding the audio power/volume knob for 10-15 seconds. For CarPlay-equipped 2018+, unplug USB if backup camera sticks. Updates are typically free during the original 4yr/50k bumper-to-bumper warranty; out-of-warranty cost varies by dealer.

Typical repair cost:$0 - $200
