“Takata inflators. While driving we noticed the speed control system stopped functioning, it would not activate or engage. We pulled over and turned off the engine, after about 1 minute we started up and once on the road it was working fine for about 5 miles or so then stopped again. Then the ABS light along with other instrument lights would come on. When we got home we called a mechanic and advised we bring it in, which we did. …”
NHTSA complaint #11192142, filed 2019-03, 58,000 miles“My 2015 Subaru Outback -- have experienced sudden and unintended acceleration. I've mentioned this to the stevens creek san jose dealership when taking my car for maintenance, but they said the behavior is as intended.”
NHTSA complaint #11361103, filed 2020-09, 55,000 miles“On february 25 I was driving my Subaru on a city street and traveling about 40 MPH. I noticed that a traffic light ahead of me would be turning red so I tried to slow down. The power brakes did not work at all. Not only did the power brakes go out but the car began to accelerate on it's own. I looked around for options and decided I could turn off into a parking lot. The brakes (not the power brakes but the back up system brakes) grabbed just enough to slow me down so that I was able to pull off safely into the parking lot. …”
NHTSA complaint #11316723, filed 2020-03, 42,000 miles“I driove out of my driveway one block to stop sign. Only going 10 or so MPH when I depressed brake to stop at stop sign . Power brakes did not respond until pedal was depressed hard to floor. Then when stopped the engine reved up and I did not take my foot off brake. The engine seemed to roar like in a very low gear. I checked gears and put it in neutral, then park and reverse, engine still roaring. But as my foot was hard on brake, it did not go into four lane traffic ahead. …”
NHTSA complaint #11015626, filed 2017-08, 35,700 miles“Cruise control (cc) caused what I thought at the time of the incident was unintended acceleration. Operation of cc is different from any cc I used in the past. The cc was already engaged and I was going about 40 MPH on a highway. I decided to increase my speed, so I pressed the 'set +' button. After a couple of seconds when I reached 43 MPH, I released the button. The car continued to accelerate to 70 MPH. Luckily the highway was empty and I was able to disengage the cc. …”
