2018 Subaru Crosstrek: hesitation when accelerating

Filed Nov 12, 2021 · Engine · OR

ECM reprogramming. I have sent in a report of 2018 Crosstrek manual transmission models like mine with acceleration delay and hesitation. There has been numerous reports of this issue among the owners. It creates hazardous condition when the driver is unexpectedly experiencing power loss or acceleration delay on lane merging situations. My car hesitates at around 2000 RPM during acceleration. I have approached Subaru dealer last year at approximately 28K miles. The car was deemed " normal". Then I called Subaru of America and I was told no such issues were reported. However, after my own research online on Crosstrek forum, this has been a known issue. In fact, tehre is a Subaru issued service bulletin on the issue described above. The Subaru service bulletin states " applicability: 2018-21 MY Crosstrek 2.0L MT Subject: Lack of power / hesitation during acceleration Number 09-77-21R Date 7/28/21 Revised 08/19/21. It also included 2017-21 MY Impreza 2.0L MT. The service bulletin describes the same problem I have experienced and described above and an ECM reprograming is needed to fix the issue. Subaru of America has not issued a recall on these models. It should have. It should have done so in 2019 or 2010 when owners of these vehicles like me has brought the issue to their attention. Please investigate and contact Subaru of America so potential accidents, hazards can be avoided. These cars need to be recalled.

There are many online posts of the same issues as my 2018 Crosstrek acceleration hesitancy, stumbling at around 2000 RPM or under light acceleration. This is particularly hazardous when entering highways. The Subaru dealership cannot find any issue with diagnostic error codes. I called Subaru of America they also reports no such recalls on the complaint above. Please investigate this for the Model year 2015 and newer Subaru Crosstreks. Many many people who owns this model has complained this on the online forum for same issue and no response or fix from Subaru.

UNKNOWN My Subaru has always had a little hesitation when accelerating. I brought this up to the dealer and they are telling me it is normal. However, in the last few months, it has gotten worse. Sometimes, when trying to accelerate into traffic, the car feels like it's going to stall or die, then it kicks in and I am able to accelerate. This is intermittent, so I never know when it's going to happen. This is a safety issue, since the hesitation could cause me to get hit.

Purchased used in August 2019 - Premium 6MT. Issue has been present since purchase. There is hesitation with acceleration, not only with extremely slow acceleration, but jerking and surging at times. Dangerous when trying to pull out into traffic and driving in general. Appears to be an issue mostly between 2k-3k and then seems to rev properly after 3k, but have noticed jerking up around 4k and over. Had taken to dealer several times before issue was reproducible, then told to be issue with buildup of carbon in fuel lines. Had fuel lines blown, problem lessened, but did not resolve - this was roughly a year ago, problem has continued and worsened. Changed air filter with no change in problem. Multiple other owners on Subaru forums have this same issue, as well as have posted on this website. Subaru needs to recognize this as an issue and resolve. No dashboard lights appear, no sensor issues have been reported. There is also a "knock" or "bloop" sound that comes from the passenger rear of the car, near the gas tank input, when pulling forward from reversing. Not sure if that is part of issue, perhaps too much air is getting into system? It's a very annoying issue; if I had known, I would have kept my Jetta.

Intermittent jerky acceleration combined with a significant loss in power during modest acceleration. At times I get no acceleration while the car jerks between 2,000 & 3,000 RPM. This is unpredictable as to when it might happen but occurs at engine speeds under 3,000 RPM regardless of vehicle speed or gear selected. My initial impression was that it is most frequent when resuming driving after having stopped for a short period which was preceded by prolonged high speed driving. Now it seems it can happen anytime. May be related to our high ambient temps this time of year. There are numerous accounts of others having the same problem on this forum. Https://www.subaruxvforum.com/threads/hesitation-while-modest-accelerating.163650/ I took it to my subaru dealership for service. They said they were able to reproduce what I describe and say it is "normal". I have owned 7 manual transmission vehicles prior to this one and can say it is anything but normal. "normal" apparently means it is a known problem and there's nothing my dealer can do about it.

There was a recall on my car for the engine stalling and hesitation. The recall did not resolve the problem. The car has been at the dealership two times. They cannot duplicate the condition. Subaru does not want to get involved to help my dealer repair the car. I am afraid to drive the car because when it does lose power its a major safety concern.
