Driving in heavy traffic in the left lane of I-78, the shifter popped out of 5th gear by itself (that is, without any human intervention). The vehicle completely lost power immediately, as it was now in neutral.
Hesitation, surging, and bucking at mid-range engine rpms. This has been a recurrent problem despite replacement of the throttle position sensor x3.
The speedometer on my vehicle became inconsistent. Sometimes it wouldn't work as soon as I started the car, other times it would stop working at any random time while driving anywhere. Eventually, when it stopped working, the odometers would stop as well. When I went to my Subaru dealer to replace the component. They told me there was a national back order and I would have to wait indefinitely for the part to come in. They also told me that they had been replacing a lot of speedometer heads on my make and year of car. I think it is unusual for a speedometer to break down after less than three years and under 65,000 miles of initial service. I have never heard of that happening on such a young car, and if it is happening on many cars of the same make and year, I think that an original part must have been defective for this car. I think that a broken speedometer is hazardous to driving on the road and therefore this should be investigated. I really don't want to worry about having to replace my speedometer every three years of my car's life. Dt.
Consumer test drove vehicle and ended up skidding into a ditch, due to design of the all wheel drive with a standard transmission, poor directional control on turns which allowed for loss of control.
