There are 1 owner-reported speed control & cruise complaints for the 2023 Subaru Ascentin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
In 2024, 2025, and 2026, I have had 2 incidents in each year where the cruise control is set to 60 to 65 mph and the cruise control then accelerates the car past 100 mph. When this occurs, tapping the break does NOT disengage the cruise control. All 6 times I have had to slam the breaks to a full dead stop while the car tries to accelerate anyway. April 4, 2026 and April 14, 2026 are the most recent occurrences and all occurrences so far for this issue have been during a downhill road incline. The dealer has dismissed the problem every time and has been unable to fix or reproduce the problem on demand. The random frequency of this problem can easily lead to a significant accident for the driver or others in the vicinity. And the lack of resolution from the Subaru dealer has lead me to report the issue here in hopes that if this is occurring for other vehicles that the company takes an actual resolution to solve the issue in their cruise control function.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
