2015 Mitsubishi Outlander Sport: shudder or vibration when accelerating

Filed Nov 9, 2026 · Engine · CO

The vehicle is currently experiencing severe hesitation during acceleration, slipping gears, high RPM surging, shuddering, jerking at low speeds, and complete loss of motive power. This behavior represents a critical safety hazard, particularly when merging onto highways or turning across oncoming traffic. I have yet to take it to a dealer due to financial hardship and concern for my safety of driving it to one. It has yet to be inspected. Manufacturer was contacted via email about current issues but have had no response yet. There were no warning lamps when I initially was driving away from dealer.

Transmission catastrophically failed while I was driving on the highway. The transmission fluid pressure sensor error code turned on. The transmission seemed to have a delay when accelerating and caused the vehicle to shake, shudder, and jerk in and out of gear. The car cannot get above 10MPH before the issue is present. A trusted and certified transmission specialist inspected the transmission and determined that it was dead and the initial failure led to other components to fail. Since there was a delay with the acceleration, it caused the car to accelerate a moment after I let off the gas pedal to apply brakes to avoid a potential collision with another vehicle. This seems to be so common of a failure it is harder to find another person who owns or drives this model that haven’t experienced the same exact problem. There is even a pending class action lawsuit in California against the manufacturer for allegedly selling their vehicles with the defective parts while knowing well the safety risk associated with the transmission.

Purchased my used vehicle at my local dealer, in which,they just received into inventory and had not been reconditioned at all ,prepping for Resale,but this vehicle was still offered to me in a nonformal fashion; since my low credit,low deposit,and prior repos that It be best if I choose that one. the vehicle has displayed symptoms of shuddering since day one. Test drive was uneventful since we remained low speed.however, Immediately and if ever drive 55-75mph there would have shuddering and erratic rpm readings but would settle once slowed and time passed.the dealer was informed the next day of this + of all oil change,car wash,detail, inspection,etc. That were also offered as apart of the deal as well and they ONLY picked up the vehicle once ,second day after financing vehicle,BUT they Only installed a "GPS" device within the vehicle and ignored and downplayed all my requests and Accounts of the details of the matter ENTIRELY. The problem persisted and the dealer personnel gave me the run around and errors electronically that pushed this matter past warranty dateline and they informed me they were not obligated to any action. 2.5 - 3 years have passed living with these unresolved issues gotten used to it until Last month on the freeway the "service transmission" light illuminated it shuddered uncontrollably to a sudden stop where it was very difficult to steer to safe location,but Once I stopped the vehicle would always start up but not would it accelerate forward or backwards every time.sometimes yes ,and some not so much. Had to be towed home and seemed to drive About half of a block distance only as have had been completely cool,as opposed to warm or hot and attempting to move forward. Shows all the symptoms of safety campaign SR-16-006. Local repair shop was uncertain diagnosing ,but Tried a complete transmission fluid exchange, Which was a fail. As far as recalls dealership,too costly at the moment for tow to/from+inspection,since the recall shows error

After being reprogrammed at the dealer my 2015 Mitsubishi Outlander Sport started to exhibit a shudder, surge condition. Finally on March 2021 while driving on a highway the CVT started to slip and the vehicle started to exhibit a lack of acceleration untill it came to a stop in the middle lane almost causing an accident. The vehicle was scanned and codes P084A, P0776 and P0843 were present. The vehicle was taken to the dealer on a tow truck and scanned again and the same codes were present. Now the dealer is telling me that I need a new CVT transmission and that warranty was denied by Mitsubishi. It is to their knowledge that these CVT transmissions are defective and they are trying to fix them with a simple CVT ECU reprogramming and oil change as per the TSB-20-23-001, also charging the owner for the oil change. It is about time that the US Government make Mitsubishi Motors issue a mandatory recall since this is a dangerous condition that can cause a major accident on US highways. It is also time for a Class Action Suit against Mitsubishi Motors for selling a defective product and refusing to repair the vehicles.

I own a 2015 mitsubishi outlander sport with 110,000 miles on it. Other than the recalls I have had no issues. Frequent oil changes, brakes, basic maintenance nothing else. Minor acceleration issues as per the recall. I was driving home on the parkway at the speed limit of 65mph and heard a sudden knock, the car shuddered and died. Thankfully I reacted quickly and pulled over the minute I knew something was wrong. I got out and there was oil all over the road way. Being a novice mechanic I pretty much knew the engine was dead. Towed to healey brs mitsubishi beacon ny and 4 days later they confirmed that there was a hole in the engine and it would need to be replaced. They had no explanation for the sudden failure but did confirm that it was sudden and not due to any lack of maintenance on my part. The car is 3 years old with sudden engine failure, on a dark highway on christmas eve. I am thankful that I was safe but still want an explanation. A friend of mine who used to work for mitsubishi informed me there is a problem with the third piston on these engines but the mechanic in beacon would not confirm either way.

Vehicle was also taken in for a recall regarding this matter but that did not resolve the problem.

At only 76,000 miles, my vehicle started to shudder when going anywhere from 10 MPH-40 MPH. This started when I was on a city street but continued on the highway. There is a lag in acceleration when going from neutral to drive. My transmission service light and check engine light went on so, I took the car in to a mitsubishi dealership and they notified me that after the diagnostic test and test driving it, they simply had to reset the sensor. After leaving the dealership, the transmission service light went on and my car was still shuddering when trying to accelerate. After getting a transmission service, which is what I was advised to do by the mitsubishi mechanics, the problem still persisted. I bought this car used from the dealership with only 40,000 miles. At 76,000 there should not be any major transmission or engine issues. I am now unable to drive my car in fear that I will end up in a car accident.

My father purchased his 2015 outlander sport in april 2015 with a total of 3 miles on it. Starting approx the end of july/beginning of august, the vehicle would "stutter" and shake upon acceleration. He promptly took it to the dealership of purchase where they told him it was a loose transmission cable and fixed it. Approx 1 week after being fixed, it began to stutter and shake again, but this time sounded like loud bangs and like the cv joint was coming apart. He took it to a different dealership and was told that the previous transmission cable fix was unsuccessful and that it was fixed "correctly this time". Over the last week, the car is acting up again - and is getting worse over time. He has taken it back to the dealership and they have done nothing. They let it sit for several days without looking at it and dad finally picked it up without anything being done to it. He was even in contact with the mitsubishi manufacturer. The vehicle is now shuddering on an almost constant basis with no explanation or help from the dealer/manufacturer and he has almost been in several accidents due to this.
