2015 Mitsubishi Outlander Sport Problems

What owners report

Owners of this model year most often describe a shudder, hesitation, and loss of power in the continuously variable transmission, typically between 40,000 and 60,000 miles, with many reporting the "Transmission Service Required" message and a replacement diagnosis. Stationary stalls and rough running with the air conditioning on, plus early brake and fuel-filler rust, also appear repeatedly in complaints. Many owners say the dealer found their vehicle was not included in the related CVT campaigns.

1. 1
   Transmission and drivetrain

   CVT shudder, hesitation and loss of power

   • 91 complaints (50%)
   • median 69,580 mi at 5.4 yrs old (59 state mileage)
   • owner-quoted repair $6,000 (median of 5 quotes)
   • filed 2015–2026

   Owners describe the vehicle hesitating or jerking when accelerating from a stop, followed by an RPM flare before the car surges forward, or a sudden loss of power on the highway. Many report the "Transmission Service Required" or transmission warning light, and dealers or independent shops diagnosed internal CVT failure or a failed valve body, recommending replacement. Several owners note the dealer said their VIN was not covered by the related transmission campaigns. Reported from a few thousand miles up past 100,000 miles, most commonly in the 40,000-60,000 mile range.

   Recall 16V563000Recall 16V5480007 related service bulletins

   What to check: Take a test drive that includes slow rolling starts and a light-throttle hill pull, watching for hesitation, RPM flare or a shudder. Ask whether the CVT fluid has been serviced and whether any transmission recall or software work was done for this VIN.

   “At 56k miles the tachometer would rev up to 5 while maintaining an even speed, then when going up hills there was no power. Very sudden issue no warning, then warning light service transmission required came on. Very frustrated - my first Mitsubishi and I want it gone. I've seen recalls for this year but my VIN says there are none.”

   NHTSA complaint #11328696, filed 2020-06, 56,000 miles

   “My vehicle was part of a recall for transmission problems. I am being told it has no current open recalls and since I am the second owner I do not have a warranty. I'm currently having to replace the transmission on my 5 year old vehicle with only 43,000 miles for the exact same issues listed in the recall.”

   Engine

   Engine stall or rough running, sometimes with A/C on

   Mentioned in 9 of 60 sampled complaints

   Complaints describe the engine stalling or sputtering at a stop, hesitation on acceleration, and rough or revving idle, with several owners noting it happens mainly when the air conditioning is running. Some report smoke or oil consumption leading to an engine replacement diagnosis. Dealers reportedly could not always reproduce the condition. Spread across the mileage range, with several reports under 40,000 miles.

   Recall 17V6090003 related service bulletins

   What to check: Check the oil level and condition, listen for idle roughness with the A/C on, and ask whether the starter relay recall (17V609000) was completed.

   2 excerpts from owner complaints in NHTSA records

   “About two months ago my vehicle started acting up on and off. When ever my A/C is on and I come to a complete stop like a red light or stop signs my truck gets to jerking, idling up and majority of the time it shuts off. It will started back up after a few minutes but I will have to turn everything off like head lights, emergency flashes. …”

   NHTSA complaint #11337522, filed 2020-07, 100,000 miles

   “I have noticed in the last 3 months vehicle hesitation, I will be stopped at a light and my car will jump forward. I've also been on the highway and have had it rev up and jump forward. I've taken it to the dealership probably about 6 times now and they always tell me there is nothing wrong and I must be imagining it. Seriously with all the other people experiencing the same thing I'm not imagining it. This is a 2015 shouldn't be having this issue.”

   Vehicle speed control

   Hesitation tied to speed control and pedal response

   • 58 complaints (32%)
   • median 37,500 mi at 4.1 yrs old (40 state mileage)
   • filed 2014–2026

   Owners describe pressing the accelerator and getting no response for several seconds, then a sudden lunge, or the car revving and creeping forward at a light. Some say the dealer found nothing wrong or advised a wheel alignment instead. Complaints often link the behavior to transmission response rather than cruise control itself. Reported from as little as a few hundred miles up to about 100,000 miles, at both low and highway speeds.

   Recall 16V5630001 related service bulletin

   What to check: During the test drive, try gentle acceleration from a full stop and a rolling acceleration from about 20 mph to sense any delayed or surging throttle response.

   2 excerpts from owner complaints in NHTSA records

   “Vehicle has delay and/or hesitation when accelerating. I was driving on the highway at 60mph trying to pass another vehicle, but the car would not accelerate after I changed lanes. Finally, after several seconds, the car responded and jumped quickly up to speed. After this occurrence, it's now happening on side streets as well going as slow as 10-20mph.”

   NHTSA complaint #11412790, filed 2021-04, 85,000 miles

   “2015 Mitsubishi started sputterring while waiting for red light and hesitates when accelerating. Check engine came on. Looks like there are other similar complaints, but when I looked up the recall my vehicle is not included.”

   Brakes

   Brake calipers sticking and premature rotor rust

   • 9 complaints (5%)
   • median 51,000 mi at 5.8 yrs old (5 state mileage, few)
   • filed 2018–2023

   Complaints describe a scraping or grinding noise, a brake pedal that needs extra travel to stop, and calipers found frozen, with rear calipers mentioned most. One owner also reported rotors rusting early. Repairs involved replacing the affected caliper. Reported from very low mileage up to around 50,000 miles, in vehicles driven in road-salt regions.

   Recall 18V070000

   What to check: Inspect rotors for heavy rust and uneven wear and feel each wheel for drag after a drive. Ask whether the parking brake caliper recall (18V070000) was performed and whether the parking brake holds on a slope.

   2 excerpts from owner complaints in NHTSA records

   “Rotars prematurely severely rusted. May be related to the fact that no protection was used for the car against rock salt as indicated in latest safety recall, which only mentioned the front cross members. If protection was not in place this would affect any area of the car that could carrode or rust where exposed.”

   NHTSA complaint #11349888, filed 2020-08, 46,132 miles

   “Service engine light, slow emissions leak. It was at the gas cap. Rust around filler tube. Needed to remove rust so gas cap makes good deal. Slow accelerate with transmission and noise from lower control arm”

   NHTSA complaint #11337940, filed 2020-07, 62,000 miles

Buying note. This model year's complaints center on CVT response and durability, so a careful extended test drive and a check for completed transmission and relay recalls matter more than cosmetics. A pre-purchase inspection that scans for stored transmission codes is worth the cost.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
