the federal safety agency issued a notice for a recall on the 2015 Subaru Outback for an exhaust pipe bellows crack which causes exhaust noise and odor which affects emission and engine performance. I had noticed our Subaru's exhaust smoke coming in through the air vents while idling and also a general loss of power for the vehicle. When I dug into the causes, I came across this recall and did the VIN look up on the federal safety agency website and also the Subaru website for active recalls. The Subaru website states that the recall was completed. I then called the subaru retailer to check if there were any records for the recall work that was completed for the federal safety agency ID Number: 10199936. They could not find any records. I called in Subaru corporate to see if they could shed any light on the recall. Subaru corporate says that the recall work was performed on August 6th, 2020 but is unable to tell me where it was performed or even if it was actually replaced. My local Subaru dealer has no records and Subaru corporate says that the work was performed. I am stuck with an exhaust leak that is potentially dangerous as time goes on where it might fail emissions. Subaru corporate has not wanted to address this or investigate the discrepancy, but instead asks me to work with the dealer to get records. The dealer says there's no records of the work ever being done. So I'm in limbo with a particularly faulty car.

We called Subaru Roadside Assistance Sunday, July 25, 2021 because the Subaru lost power, as though it were out of gas, but the gage showed we had over an eighth of a tank. We mentioned this to the roadside assistant Rep. several times. She took our cell and credit card #s and said she ordered us a tow truck. I asked if the driver will have a gas can with. She said, "Well do you need a tow or fuel". Again we repeated we didn't know and explained again what happened. She said it would be 60-90 minutes. It was 94 degrees, we had no water, no shade, it was horrible. After 90 minutes still nobody came. We called again to see how much longer it would be. COME TO FIND OUT, THEY DIDN'T SEND ANYONE!!!. They said they didn't know if we needed a toe or fuel, so they didn't send anyone, didn't call, NOTHING. They said it would be another 90 minutes. We told them to forget it, hung up and went to a nearby house and the guy gave us a bottle of water and from a gas can, provided us enough gas to get to the next gas station 11 miles away. I tried calling subaru headquarters to report the issue and to let them know if our credit card was charged, they need to reimburse it since we did not receive service, but I was on hold for so long, I hung up and emailed them - 3 times and I NEVER heard anything back from them. So here I am reporting to not rely on their gas gage and reporting a safety concern that they would leave people in massive heat, probably would in the terrible cold as well. They do not call to let you know that nobody is coming. Subaru roadside assistance is one big joke. Subaru service is a big joke because obviously they don't care since they never responded to any of my emails. Needless to say, we will never call their roadside assistance again and will NEVER buy a subaru again since they have shown lack of interest. Thank you.

1. My battery failed, so I replaced it. I didn’t keep the failed one. 2. Problem started while driving w/ a handicapped, elderly passenger in remote rural area at night. Help at least 1/2-hr. away. No open garages. Frightening. 3. AAA confirmed. 4. AAA inspected. 5. My Check Engine light came on, Cruise Control stopped working. Pulled over, ck’d manual, nothing noted about battery, no Battery warning light. Car started up, drove home very slowly, stopping occasionally. Next morning, car wouldn’t start, called AAA to take to mechanic (charge $150 to check system). There was no previous warning that battery was losing power. AAA found battery problem. No engine problem. Replaced. No more lights. Very disappointed that much worry could have been avoided.
