“My 2006 Subaru Outback has had a code p2138 issue for over two months now. In many cases I am in the car with my 4 year old son and end up being in danger for no reason. Loosing 99% of power while going to school or to the store. All attempts to fix this issue have not worked and the car itself is thought of as a death trap in our house. Subaru disregards the code and offers no fix. Please issue a recall. Lives are at risk.”
NHTSA complaint #10626319, filed 2014-08, 67,000 miles“Ringland issue once again another ringland issue this is with my 2006 Subaru Outback xt. Yes, this car is out of warranty but has been driven gently by a grandmother and serviced with the precision of a formula race car. Why has Subaru not just come out and said yes our vehicles from 2005-2006 were garbage and the ringlands were junk. I can't believe I am even thinking about replacing a stock ringland on a vechicle...no other car....none has had as many issues with ringlands as Subaru. …”
NHTSA complaint #10969593, filed 2017-03, 105 miles“I recently had p2138.. One time. No throttle response, stopped on a hill on a 2 lane road, on a curve, in big sur.. Not good. Rolled backwards down hill after the ones behind had all passed me. Turned off car, waited for 10 minutes, then it fixed itself after a restart. Jiggled the pedal connector and it has been gone for the last 2 weeks while waiting for my mechanic to have room in his schedule to replace my throttle pedal (which has a pedal position sensor), two days from now.”
NHTSA complaint #10781463, filed 2015-10, 175,000 miles“Unexpectedly, while driving, the check engine light will come on, the car will idle high, the accelerator pedal will not respond, and the cruise control light will also come on. The car won't move even while pressing down on the accelerator pedal. I have to pull off the road, turn the car off, and wait until the car starts, the idle returns to normal, and the accelerator pedal responds. This has happened once last year and twice this year; the last time being 2/17/17. I was lucky. The first time it happened I was on a country road. …”
NHTSA complaint #10959658, filed 2017-03, 130,000 miles“Just received takata recall letter stating there are now sufficient parts available. At the same time my check engine light came on and cruise light started flashing. I made an appointment for the recall work and to have the car checked out. I googled this and found that a code p2138 is found with this occurrence and it seems to be happening with many of these vehicles. My wife called me on her way home from work and said the car would not accelerate. She pulled off of the highway into a parking lot. I drove to her location. …”
