Most recent owner complaints, unedited.
First the fuel gauge was erratic then failed, then the speedometer pegged and is failing to show even close to true speed as in showing 100+MPH in an actual +/-35mph range. Circumstances match description of common problems with instrument cluster failures on that make and model.
When operating at low speeds,I would turn the wheel to left and steering felt sluggish,felt like a rubbing and feels like vehicle would stall. Brought to local garage, they were able to duplicate problem but had solutions. They checked power steering pump, brake sensors, serpentine belt, fluids...all checked out fine.
