Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
No new NHTSA cruise control complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Owners report sudden unwanted acceleration events, brake failures, and transmission control computer faults on 2015 Corollas, often at low mileage, with some resulting in crashes. Dealerships have struggled to diagnose these problems, and repairs have been slow or incomplete.
Owners report sudden acceleration that persists even when brakes are applied, occurring at both low speeds (parking, reversing) and moderate highway speeds (25–40 mph). Multiple owners describe the vehicle accelerating immediately after shifting into Drive or Reverse, with brakes proving unresponsive; some gained control by shifting to Neutral and applying the brake. These incidents happened at mileages as low as 980 miles up to 54,000 miles, with no warning lights preceding the failures.
A separate electrical issue involved the transmission control computer shorting out, causing complete loss of power at highway speeds—the odometer's Drive indicator would vanish, check light flash, engine stall, then power restore when the display reappeared. One dealership technician noted he'd seen this once before but the information wasn't shared across the service department.
One owner reported a computer fault sending false codes, causing the engine to refuse acceleration from a stop or move only very slowly; battery reset fixed it temporarily before the problem recurred within a day. The mechanic noted the computer lost track of transmission gear position.
Dealerships tested vehicles but initially could not reproduce the problems during solo test drives; issues reappeared once owners were present. One transmission control computer was identified for replacement but had not arrived at the time of reporting.

Failure modes owners describe
Sudden unwanted acceleration under braking
Vehicle accelerates when driver applies brake pedal or shifts into gear, brake pedal becomes unresponsive. Occurs at various speeds and situations (parking, reversing, forward driving). Drivers report shifting to neutral to regain control. Happens multiple times for some owners.
When: Low to moderate mileage (980–54,000 miles); incidents occurred at speeds ranging 5–40 mph
Symptoms owners cite: Vehicle accelerates while brake pedal is depressed; Brake pedal unresponsive; Unwanted acceleration on gear shift (into Drive or Reverse); Loud engine revving; No warning lights or symptoms before failure; Happens repeatedly for some vehicles
Repairs/costs cited: Dealerships unable to diagnose or reproduce issues during test drives without owner present. One instance: transmission computer was shorted out, requiring computer replacement; parts not received at time of reporting.
Recalls/TSBs owners mention: Two instances of dealer notification with no diagnosis found. One transmission control computer replaced (pending delivery). No recalls mentioned.
Transmission computer electrical fault / loss of drivetrain signal
Transmission control computer experiences electrical fault or connection issue, causing loss of communication with transmission and engine control modules. Display shows 'D' (Drive) disappearing from odometer; ECHO light flashes; vehicle loses all power and stalls. Power returns when 'D' reappears. Computer unable to locate problem code.
When: At 35–40 mph cruising speed; failure occurred repeatedly while driving highway speeds
Symptoms owners cite: Drive gear indicator disappears from odometer display; Check Engine light (ECHO) flashes; Complete loss of power to vehicle; Vehicle stalls; Power returns intermittently when display resets; Dealership unable to diagnose first test drive; reproduced on second test drive with owner present
Repairs/costs cited: Dealership identified transmission control computer shorting out. Replacement computer ordered but not yet installed at time of report. Owner continuing to drive vehicle and avoiding highway.
Recalls/TSBs owners mention: Dealership initially found no computer issue; second inspection identified faulty transmission control computer. No recall or TSB mentioned.
Erratic engine control / false diagnostic codes
Vehicle engine control computer sends false or conflicting codes causing intermittent loss of acceleration capability. Vehicle will not accelerate from a stop or accelerates very slowly. Hard reset (battery disconnect/reconnect) temporarily clears issue, but problem reoccurs within a day.
When: At 54,000+ miles; happens repeatedly after each reset cycle
Symptoms owners cite: Computer sends false/incorrect diagnostic codes; Vehicle refuses to accelerate from complete stop or accelerates very slowly; Loss of normal engine response; Intermittent nature; problem goes away temporarily after reset
Repairs/costs cited: Mechanic stated computer does not know what gear vehicle is in. Battery disconnect/reconnect (hard reset) provides temporary fix lasting a day or so before problem repeats.

What owners are reporting 2 most recent
Tl* the contact owns a 2015 Toyota corolla. When the vehicle was started, it suddenly accelerated on its own. After switching the transmission from park into reverse, the vehicle suddenly accelerated backwards and crashed into a cement block. The driver then shifted into drive and the vehicle accelerated forward, nearly crashing into a second vehicle. During the incident, the brake pedal was…
