2016 Subaru Outback: gas smell in the cabin

Filed Jul 20, 2026 · Engine · CO

There is a crack in the exhaust manifold and the exhaust smell is entering the cabin affecting driver and passengers' health. The problem has been confirmed by a Subaru dealer and an independent mechanic. There were no warning lights, I was made aware after routine maintenance by an independent mechanic. The same part has failed in multiple Subaru models: Recall WUJ-95 (SOA says my car is not covered in the recall/campaign due to my car's production date being 24 days after the "Affected Production Dates") . Additionally, Subaru of America extended the exhaust pipe warranty on the same part on other models, as late as 2018, so the part continued to be in use and problematic. Subaru of America says replacing the part is not covered by a recall for my car, however I feel strongly that it SOA should replace the part due to the proximity of my production date and the continued issues with the part across multiple models.

My 2016 Subaru Outback, manufactured 23 business days after the end date of recall WUJ-95, has the same exhaust system and now the same exhaust system failure as the cars covered under the recall. My car is available for inspection. This exhaust failure poses a risk of carbon monoxide poisioning. The problem in my car was identified by an independent mechanic who works exclusively on Subarus and has seen this failure in other clients' vehicles. He referred me to Subaru for repairs and recommended I look into why I hadn't received a recall notice. I contacted Subaru, opened a case, then didn't recieve a response in the timeframe they defined. After waiting a few days, I called back to learned my case had been closed. Their customer advocacy representative responded the next week and said my car was not recalled because it was manufactured on 11/3/2015, after the end date of the recall on 9/30/2015. She also cited a lack of service history with a Subaru retailer (I offered to provide records) and being out of warranty by time and miles (I mentioned 2017-18 Foresters received warranty extensions to 15 years or 150K miles for this failure.) I asked what their escalation process is for making exceptions and was told the representative was the only customer-facing person I would be able to speak with about this and she declined to offer any assistance, but did offer a loyalty discount on a new vehicle. My car has not been inspected by anyone else. I'm willing to take it to anyone who should look at it. There were no warning lights or messages related to the issue. It was diagnosed when I took the car in for regular maintenance and it explains the more noticable smell of exhaust in the car, that I had attributed to other traffic, when I'm sitting at stop lights.

Recently, My daughter noticed the strong smell of exhaust in the car. It turns out the there is a leak in the exhaust manifold. Subaru issued SERVICE PROGRAM BULLETIN WUJ-95R to address a issue where a bellows in the exhaust cracked and allowed the leakage of exhaust gases in front of the CC, releasing noxious gases into the air and into the driver compartment. Problem is they only applied this to a small amount of the production of the 2016 outback. This issue has been occurring on 2015 to 2019 models since and they did not include them in the recall. To fix this issue because of a design flaw the CC (Catalytic Converter) also needs to be replaced at a cost of over 3000 dollars. My ask is that they should extend this recall to cover all the cars with this design as it is a serious health issue to drivers of the cars. This is not an issue where rust is causing exhaust to break out, This is a manufacturing design issue where cars are having the issue which were only a couple years old. In my case, the Bellows in question were replaced by the previous owner at less than 4 years old and I did not know about that. So when that repair failed(not the permanent fix offered in the service bulletin) Subaru told me I am on my own though the CC should be covered to 150K in New York State. I feel they should be responsible to address this issue for all the models with the defective design.

Car exhaust inside the vehicle when driving at low speeds, idling, or parked into the cab of the vehicle. Only way to stop the exhaust fumes is to use the recirculate interior air. Rear hatch hydraulics are failing, hatch will not open completely and partially shuts when opened. When driving very loud squeaking from vehicle.

- Leaking exhaust at bellow - I had to replace the catalytic converter. - I have a bad sense of smell. I did not notice it was an issue until a passenger of mine noted a smell of exhaust while we were driving. - I read a bulletin on your websites that there was a recall of other 2016 Subaru Outbacks for this same issue. I understand that my car was not a part of this recall because of the manufacturing date, but I found it to be an odd coincidence that my car has the same issue. When I visited another mechanic initially, he immediately alerted me that he has seen many Subaru vehicles with this same issue and directed me to a Subaru dealership. - My car was finally diagnosed and repaired at Marin Subaru of CA.

Exhaust manifold cracked completely through, causing exhaust fumes in the interior of the car. There is a recall on this part for 2015/16 outback, but only includes certain manufacture dates, my car is not currently included in the recall. This part is clearly defective as the break occurred suddenly under normal driving conditions, pipe is clean, no rust.

on 2/8/22 I brought my car in for service to an independent repair shop. The service was for the 120k standard service. I had been noticing exhaust smells. They checked the exhaust and found "exhaust leak from center exhaust flange, and exhaust leave from exhaust manifold". They recommended a complete replacement of the exhaust manifold "under Subaru recall". They printed the recall for me. It is WUJ-95. Which recalls 2015-2016 outbacks for this issue. When I contacted the dealer they indicated my vehicle was not under this recall. Subaru Customer care indicated the same as did your website. Subaru said that the recall was initiated by the federal safety agency and that until the federal safety agency indicated my vehicle was included in the recall they would not repair it. My vehicle has exactly the same issue as what was found for the recall. The only thing I can assume is that my actual 2016 Subaru outback was manufactured after 9/30/15. I cannot find the exact date of manufacture so cannot tell if that is the issue. However, that actual manufacture date should not be controlling as my 2016 outback has exactly the same issue as the recall. If 2016 outbacks manufactured after 9/30/15 have this same issue they should be included in this recall. I am asking you to review this issue and include my vehicle in the recall.

The front exhaust pipe bellows cracked. When the car was cold started and then driven, a rattle came from the engine bay when driven at 2500 RPM. When the engine warms up, the rattle goes away. When the car is parked, exhaust fumes can be smelled from outside the car.
