    On the 2008-2012 Mitsubishi Outlander, on 2008-2012 Outlanders fitted with the 4B11 or 4B12 four-cylinder engine, the flange of the automatic drive belt tensioner may crack. A cracked flange lets the accessory drive belt detach from the engine. For the driver, the sequence is what matters: with the belt off, the battery begins to discharge and the engine eventually stalls, which NHTSA identifies as an increased risk of a crash — losing the engine on a highway ramp or in an intersection is the scenario behind the high severity rating. Coverage depends on the engine, not just the year, so V6 Outlanders and other engine variants are outside this campaign. Mitsubishi's filing counts 141,053 vehicles, but that figure is campaign-wide across every model in the recall, not an Outlander-only number.

    Common Symptoms

    • Drive belt detaches from the engine
    • Battery goes flat / discharges while driving
    • Engine stalls

    How to Fix

    The fix is free at any Mitsubishi dealer under recall 18V069000 (Mitsubishi's own number is SR-18-001). The dealer removes the original belt tensioner and installs a replacement with a revised, stronger flange shape; there is no charge for parts or labor. Notices went out starting March 27, 2018. Because the Outlanders involved are now well into the used market, check your specific VIN at nhtsa.gov/recalls rather than assuming a previous owner had it done — recall repairs stay free indefinitely and follow the vehicle, not the buyer. Questions can go to Mitsubishi customer service at 1-888-648-7820.

    On the 2007-2020 Mitsubishi Outlander 6B31 3.0L V6, a recurring and expensive owner mistake on V6 Outlanders: buyers and even some independent shops assume a modern V6 has a timing chain, so the belt never gets changed. The 6B31 3.0L V6 fitted to the Outlander runs a rubber timing belt with a service interval around 105,000 miles. Worse, the design changed: early 2007-2009 engines used pistons with valve reliefs and are non-interference, so a snapped belt merely stranded the car, while later 6B31s are interference — a broken belt lets the pistons hit open valves and typically bends valves and damages guides. Mitsubishi enthusiast forum threads are full of owners discovering the belt only after it fails, and of 'belt or chain?' confusion threads. The 2.4L four-cylinder in the same body is chain-driven, which is exactly why the confusion persists.

    Common Symptoms

    • Engine cranks but will not start after a bang or rattle
    • Sudden loss of power while driving
    • Rattling or squealing from the front timing cover
    • Rough running with multiple misfires after a timing event
    • Crank/cam correlation fault stored

    How to Fix

    Verify what your engine has before assuming: if it is the 3.0L V6, it is a belt. Replace the timing belt, tensioner, idler pulleys and water pump as a kit at the specified interval (roughly 105k miles, or on age if the car is old and low-mileage — the belt degrades with time and heat cycles, not just miles). Get the previous owner's records; if there is no documented belt service and the car is near or past the interval, treat it as due. If a belt has already broken on a 2010-or-later V6, do a compression or leak-down test before spending money — bent valves usually mean cylinder head removal, and on a high-mileage car a used engine is often cheaper than the head repair.

    On the 2008-2011 Mitsubishi Outlander, if your 2008-2011 Outlander has a 4B1-series engine, it is part of Mitsubishi recall 14V562000. On these engines a single belt-and-pulley arrangement turns the alternator, the cooling fan and — on vehicles so equipped — the power steering pump. Mitsubishi found the pulleys can wear unusually, letting the belt detach. Once the belt is gone the alternator no longer charges the battery, the battery drains, and the engine can stall, which is the crash risk NHTSA cites. The recall population of 165,923 vehicles is the total for the entire campaign across all the Mitsubishi models it names, not an Outlander-specific count; the 2011 Outlander Sport was covered as well.

    Common Symptoms

    • Drive belt detaches from the engine
    • Battery goes flat / charging system stops working
    • Engine stall
    • Heavier steering if the power steering pump is belt-driven

    How to Fix

    Have it done free of charge at a Mitsubishi dealer under recall SR-14-009. The dealer swaps the original belt for a rubber drive belt and checks the drive pulleys, replacing any that are excessively worn. Owner notification started October 15, 2014, so on a vehicle this age the work may already have been completed — check your VIN at nhtsa.gov/recalls to be sure, or call Mitsubishi at 1-888-648-7820.

    On the 2008-2013 Mitsubishi Outlander, if your 2008-2013 Outlander has ever lived in a road-salt state, it is part of Mitsubishi recall 20V279000 (Mitsubishi campaign SR-20-003). Salt water exposure corrodes the front cross member — the structural crossbeam the front lower control arms bolt into. As that corrosion progresses, a front lower control arm can pull free of the cross member. NHTSA's stated consequence is blunt: a detached front control arm can cause loss of vehicle control and a crash. Coverage is registration-based rather than sales-based: an Outlander originally sold in, or at any point registered in, Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia or Wisconsin is included. The recall covers about 141,200 vehicles campaign-wide across every Mitsubishi model named in it.

    Common Symptoms

    • Sudden loss of control if a front lower control arm separates from the cross member
    • Heavy rust/corrosion visible on the front cross member under the front of the vehicle

    How to Fix

    This is a free dealer repair. Book the Outlander in under recall SR-20-003 and the dealer will inspect the front cross member; light corrosion is treated with a sealing/anti-corrosion agent, while heavier corrosion means the front cross member is replaced with a new one. Owner notification started August 7, 2020. Check your VIN at nhtsa.gov/recalls to see whether the recall is still open on your vehicle, or contact Mitsubishi customer service at 1-888-648-7820.

    On the 2007-2020 Mitsubishi Outlander, the Jatco CVT in the Outlander is prone to premature failure, particularly under heavy loads and in hot climates. The CVT belt and pulleys wear prematurely, leading to slipping, shuddering, and eventual complete transmission failure, often between 60,000 and 100,000 miles.

    Common Symptoms

    • Transmission shuddering during acceleration
    • Loss of power at highway speeds
    • Whining noise increasing with speed
    • CVT overheating warning

    How to Fix

    Change CVT fluid every 30,000 miles using Mitsubishi DiaQueen CVTF-J4. Avoid aggressive driving and towing near maximum capacity. If the CVT fails, replacement with a remanufactured unit is more cost-effective than rebuild.

    Typical repair cost:$3,000 - $7,000

    On the 2007-2020 Mitsubishi Outlander, the AC compressor in the Outlander is prone to premature failure, with the internal clutch bearing seizing or the compressor developing internal leaks. Failure typically occurs between 60,000 and 90,000 miles, leaving the vehicle without air conditioning.

    Common Symptoms

    • AC blowing warm air
    • Clicking or grinding from compressor
    • Intermittent cooling
    • Refrigerant leak detected

    How to Fix

    Replace the AC compressor, receiver/drier, and expansion valve as a complete system. Flush the AC lines to remove debris from the failed compressor. Use the correct PAG oil specification for the replacement unit.
