problem #5

Nov 012011

Legacy 4-cyl

  • 6,000 miles


On two separate occasions, I put the vehicle into drive and removed my foot from the brake, before accelerating; the car rolled forward in a shuttering manor and then lunged forward several feet (4-6 ft). The rpms seemed to drop (500-700 RPM) and then spike (1,200-1,500 RPM) with no acceleration at time of the incident. I immediately applied the brake and stopped for several seconds. I then took my foot off the brake again and the vehicle seemed to run fine. The engine was not cold at the time on occurrence; it had been driven approx. 30 minutes before the incident.

6 speed manual transmission. Vehicle stalls, and rough idles intermittently while at stop light or other traffic control. Vehicle also stalled while on highway twice disabling power steering, and power braking. Brought back to dealer and they were unable to replicate issue. Issue occurred again, brought back to dealer 2nd time same results. 3rd time issue was replicated while I was in vehicle with tech. Technician stated that they will address it. Left over weekend. Tuesday dealer notified me that the vehicle was experiencing a power draw after the window or electronic brake were used, and the factory advised that the computer would need to be "re-flashed" but currently, there is no re-flash program developed, and there is no time line as to when it would be. Contacted Subaru America cust. Serv. District manager test drove and was unable to replicate. So as far as the dealer and Subaru are concerned, there is no issue. Vehicle still stalls intermittently. Filed complaint with ct dvm lemon law, and now with NHTSA.

Feeling unsteady on highway speeds 60+, whistle noise in heater vent not fixed by dealer, volume buttons on steering wheel not working brought in 4 times to dealer to fix, whistle noise in window was told is the mirrors outside however when roll window up and down several times...it hits the top hard, but shuts fully and noise stops sound like window will break, hard start 3X dealer asked where I buy my gas, hood of car vibrates on highway, heat comes out strong on windshield on foot setting, dealer said normal and showed map however its the same as setting it to foot and windshield setting, mileage: On full says 430, I clocked it and when it showed 380 we had only drove 17 miles inaccurate. Cup holder broke after putting water bottle in it was replaced by dealer, transmission shifting down by bucking dealer stated memorizes driving. Inside scratches easy cheap. Have case w Subaru of America but getting nowhere.

Drumming noise that appears to be coming from the rear-end of the vehicle, can be heard and vibrations felt inside the vehicle, when the engine is on and the vehicle is at rest or moving. Subaru of America factory and dealership service technicians are not certain that the issue is the fuel pump, but soa factory has instructed the dealership to replace it.

I started vehicle in driveway as usual. Put vehicle in reverse, slowly letting foot off brake, engine began to sputter and sounded like it was about to stall. Braked and put in park to let engine warm for a few more minutes. I proceeded to drive without incident.
