Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“At approximately 85k total miles, is250 automatic began dropping from 5-6k RPM to 2-3k RPM whenever changing road grade to an incline or decline, usually above 50 MPH, dropping to 35 MPH on the highway. To maintain proper speed, I would have to downshift from d to s and floor the accelerator. Traction control, parking brake, and ABS lights would sometimes coincide with this problem. This continued until I sold the is250 at 88k miles.”
