2011 Subaru Legacy: adaptive cruise control problems

Filed Apr 25, 2021 · Transmission · 138,000 miles · NJ

First the vehicle started with a screeching noise and the RPM's would spike. Apparently if the CVT transmission slipping. I took the vehicle in variations occasions to the dealer. Reached out subaru USA. Sent video of the occurrence and they indicated they could not classify the occurrence and found it inconclusive. I notice it would occur in temperatures lower then 45 degrees fahrenheit. Months later the vehicle started flashing various warning lights such as check engine, cruise control, vehicle dynamics control. Took the car to local dealer and was diagnosed as a oxygen sensor. But what started occurring after the repair was startling and dangerous. The vehicle now started stalling out when I pressed on the brakes to stop. On long drives this would not occur. It often happens when driving locally and stopping at intersections. What I learned to and implemented was as the stalling was starting to occur you would get a jittering from the vehicle I would shift the car to neutral and the car would not stall. This is neither the norm or safe, but safer then stalling in an intersection with vehicles coming at you. This issue still continues to occur. I have not bothered with the dealer nor subaru because my last issue with the transmission was never resolved, I'm able to counter the stalling but my wife who has to go out with my 1yr old son and 10 yr daughter is scared to use the vehicle because if it was to stall in an intersection as she is trying to cross in the vehicle a major accident can occur. Please help and investigate this issue that I am sure it is happening to other subaru owners. Thank you

While in motion at highway speeds and when attempting to utilize the coast function on the cruise control to temporarily disengage acceleration and/or speed control, the system fails to stop propulsion and continues to accelerate and/or maintain existing speed thereby causing a safety hazard.

Vehicle was stopped at a red light. Upon light acceleration, check engine light came on (and stayed on), parking brake light began to blink, cruise control indicator began to blink, and traction control light came on and stayed on. Driver did not detect any slippage. Authorized subaru dealer found no problem with oil control valve (ocv) despite computer code indicating potential problem with that part. Dealer, however, indicated oil flush, rather than simply an oil change, was necessary despite less than 5,000 miles since previous oil change. Dealer asserted that oil level was not low, however. Cause of what triggered the indicators to be set off remains unclear.

Dash trouble lights flashing constantly on and off check engine, brake failure, all wheel drive failure, cruise control failure, temperature light, oil warning light, engine not engaging when gas pedal depressed. Car wobbles side to side at speeds greater than 60 MPH, steering wheel excessive vibration. Currently in repair for over one week. Appears dealership can not correct. When originally reported to service advisor he stated to bring in the car in one week. Took car in immediately per owners manual and he then stated he could not release car back to me because it was unsafe to drive. This is a new vehicle with 1500 miles.
