The 2018-2024 Outlander PHEV uses a 2.4L Atkinson-cycle engine paired with dual electric motors and a complex drivetrain. While the hybrid system itself is fairly robust, this platform suffers from catastrophic engine failures, transmission oil cooler leaks, and various software/sensor gremlins that can disable critical safety systems.
Symptoms: Sudden loss of power or engine shuts down without warning, Metallic knocking or rattling from engine bay, Oil consumption increases dramatically before failure, Check engine light with misfire or low oil pressure codes
Fix: Complete engine rebuild or short block replacement required. This involves 18-25 hours labor for engine removal, disassembly, machine work, and reinstallation. Root cause appears to be oil starvation in certain driving conditions (frequent short trips in EV mode followed by hard acceleration). Pistons, rings, bearings, and sometimes crankshaft need replacement.
Estimated cost: $8,000-14,000
Transmission Oil Cooler Leaks
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Pink or red fluid pooling under vehicle, Transmission fluid level drops between services, Overheating warning on longer highway drives, Visible corrosion or seepage around cooler lines at radiator
Fix: Oil cooler lines corrode where they connect to the transmission or radiator. Requires replacement of cooler lines and sometimes the entire cooler assembly. 3-5 hours labor including fluid refill and system bleed. This is a known weak point on the CVT-style transmission used in PHEV models.
Estimated cost: $800-1,400
Transmission Mount Failure
Common · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Clunking noise during transitions between EV and engine mode, Excessive vibration at idle when engine is running, Visible sagging or tearing of rubber mount, Drivetrain feels loose or jerky during acceleration
Fix: The transmission mount deteriorates prematurely, likely due to the constant switching between electric and engine propulsion. Replacement takes 2-3 hours and requires partial subframe drop to access. Use OEM or upgraded aftermarket mounts—cheap replacements fail quickly.
Estimated cost: $400-700
Head Gasket Failure
Occasional · high severity
Typical onset: 70,000-110,000 mi
Symptoms: White smoke from exhaust on cold starts, Coolant loss with no visible leaks, Overheating without obvious cause, Oil appears milky or frothy on dipstick, Bubbles in coolant reservoir when engine running
Fix: Head gasket failure often follows or accompanies the piston/bearing issues—engine runs lean or hot due to software not optimizing combustion properly. Both heads typically need resurfacing. 14-18 hours labor, often discovered during diagnosis of other engine problems.
Estimated cost: $3,500-5,500
Backup Camera/Sonar Sensor Software Failures
Occasional · low severity
Symptoms: Backup camera screen goes black or freezes, Parking sensors beep erratically or not at all, Display shows 'camera unavailable' message, Forward collision warning activates randomly or stops working
Fix: Software glitches in the integrated safety systems cause intermittent failures. TSBs and recalls address some issues, but often requires dealership software reflash (1-2 hours). Occasionally the camera module itself fails and needs replacement, but start with software updates first.
Estimated cost: $150-600
Liftgate Strut Failure
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Rear hatch won't stay open or falls unexpectedly, Hatch opens slowly or requires manual assistance, Visible fluid leaking from strut body, Strut feels weak when lifting hatch manually
Fix: Factory struts are undersized for the hatch weight, especially with aftermarket accessories. Simple replacement job, 0.5-1 hour labor for both sides. Always replace in pairs. Recall campaigns covered some VINs but not all.
Estimated cost: $200-400
12V Battery Drain/Electrical Gremlins
Common · medium severity
Symptoms: Vehicle won't start after sitting 3-5 days despite charged traction battery, Dashboard lights flicker or random warnings appear, Infotainment system reboots on its own, Battery tests fine but drains overnight
Fix: The PHEV has numerous modules that stay partially awake, draining the small 12V battery. Often no single fix—requires software updates, checking for aftermarket accessory draws, and sometimes replacing the 12V battery with a higher-CCA unit. Diagnosis can take 1-3 hours if parasitic draw testing is needed.
Estimated cost: $150-800
Owner tips
Change engine oil every 5,000 miles MAX—the Atkinson engine runs hot and oil degrades quickly despite the vehicle often recommending longer intervals.
After driving in EV mode, let the engine warm up fully at least once a week to prevent carbon buildup and ensure proper lubrication.
Use a battery maintainer if the vehicle sits unused for more than a week; the 12V battery is marginal for the electrical load.
Check for open recalls and TSBs regularly; Mitsubishi has issued multiple software updates that address real problems.
Skip it unless you get a screaming deal and can afford a potential engine replacement—the catastrophic failures are too common and too expensive for a used PHEV gamble.

2020-05-18
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2019-2020 Outlander and 2019 Outlander PHEV vehicles. The seat belt for the right side second-row seat may have been assembled incorrectly.
Consequence: An incorrectly assembled seat belt may not properly restrain the occupant, increasing the risk of injury in a crash.
Remedy: MMNA will notify owners, and dealers will inspect the right side second-row seat belt and replace it as necessary, free of charge. This recall began June 17, 2020. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-20-002.
ELECTRICAL SYSTEM:SOFTWARE · 18V620000
2018-09-14
Mitsubishi Motors North America (MMNA) is recalling certain 2018 Mitsubishi Outlander PHEV, Outlander Sport, 2018-2019 Eclipse Cross, and 2017-2018 Outlander vehicles equipped with a Forward Collision Mitigation (FCM) system that detects pedestrians. Due to incorrect software, the FCM-ECU (Electronic Control Unit) may apply braking for longer than needed, even after a pedestrian is no longer detected.
Consequence: If the FCM-ECU software activates the brake for longer than necessary, the driver may react by applying additional braking. The resulting rapid deceleration of the vehicle can increase the risk of a rear-end collision.
Remedy: MMNA will notify owners, and dealers will reprogram the FCM-ECU software with updated software, free of charge. The recall is began October 16, 2018. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-18-007.
FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL · 18V621000

(MMNA) is recalling certain 2018 Mitsubishi Outlander Sport vehicles equipped with a Forward Collision Mitigation (FCM) system and 2018 Mitsubishi Outlander PHEV and Eclipse Cross vehicles and 2017-2018 Outlander vehicles equipped with an Adaptive Cruise Control (ACC) system and/or an Electric Parking Brake (EPB) system. The software for the Hydraulic Unit Electronic Control Unit (ECU) may be incorrect, possibly preventing the intervention of a safety system such as automatic emergency braking, Anti-lock Braking (ABS), Electronic Stability Control (ESC), or the Brake Auto Hold (BAH) function when any of these systems are in use.
Consequence: If the safety systems do not function as intended, it can increase the risk of a crash.
Remedy: MMNA will notify owners, and dealers will update the Hydraulic Unit-ECU software, free of charge. The recall began October 16, 2018. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-18-008.
