2024 Toyota Grand Highlander cruise control problems

The failure pattern owners describe
Owners of the 2024 Toyota Grand Highlander describe a pattern of acceleration failure from a complete stop that creates real hazard. When pressing the gas pedal after a traffic light, stop sign, or parking lot, the vehicle does not respond for 1 to 5 seconds, then suddenly surges forward. No warning lights appear. The problem is sporadic but frequent—some owners hit it multiple times a day or several times a month. It happens on slight inclines, in traffic, and at intersections where the delay leaves them exposed or unable to complete turns.
On hybrid models, some owners report the electric motor engages but the gas engine does not, stranding them without adequate power. One owner experiencing unintended acceleration in a garage cited a brake delay; the manufacturer's investigator blamed driver error.
A related transmission issue involves 2–3 second delays shifting from reverse to drive. One owner had software update T-SB-0017-24 applied, which helped briefly. Another had a system flash performed; both reported only temporary relief or no resolution. Dealers consistently tell owners they cannot diagnose or fix the problem without error codes, and in multiple cases claim they cannot reproduce the issue even when owners demonstrate it at the same location.
No diagnostic codes are stored. The problem remains undocumented and unresolved across multiple dealer visits.
Failure modes owners describe
Acceleration Hesitation / Lag from Complete Stop
Vehicle fails to accelerate or hesitates significantly (1–5 seconds) when the driver presses the accelerator pedal after coming to a full stop. In some cases, the vehicle feels as though it is in neutral despite being in Drive, or the engine fails to engage while the electric motor runs. This occurs intermittently, often on slight inclines or in traffic situations.
When: At stops, intersections, traffic lights, stop signs, and when pulling out of parking lots. Some owners report it happens more frequently on slight inclines. Occurs repeatedly throughout drives, multiple times per month or per day.
Symptoms owners cite: No throttle response for 1–5 seconds after pressing accelerator; Vehicle feels like it is coasting or in neutral despite being in Drive; Electric motor runs but gas engine fails to engage (hybrid models); Sudden surge forward once power finally engages; No warning lights or error messages present before or during the event; Sporadic occurrence; not reproducible on demand at dealership
Repairs/costs cited: Software update T-SB-0017-24 was performed on at least one vehicle; owner reported temporary improvement for a few days before issue recurred. One dealer performed a system flash/reset which helped with shifting but did not resolve delays. Other dealers report unable to replicate issue during service visits despite owners demonstrating the problem at the same location.
Recalls/TSBs owners mention: Software update T-SB-0017-24 issued; temporary relief only. One manufacturer investigator concluded no trouble found after unintended acceleration incident. Dealers consistently unable or unwilling to address issue without diagnostic codes.
Transmission Engagement Delay (Reverse to Drive)
When shifting from reverse to drive, or engaging drive from a complete stop, there is a 2–3 second delay before the transmission engages and the vehicle moves. This is separate from engine acceleration lag and appears to be a transmission response issue.
When: When shifting from reverse to drive; when starting from a complete stop. Sporadic; not consistently reproducible.
Symptoms owners cite: 2–3 second delay between shift command and vehicle movement; Vehicle remains stationary after shifting into Drive; No warning lights or error messages
Repairs/costs cited: One dealer performed a system flash/reset; owner reported this helped with shifting issues but did not fully resolve delays. Another dealer claimed the delay was 'normal behavior' for a CVT, though the vehicle (XLE model) does not have a CVT.
Recalls/TSBs owners mention: Dealer claims delay is normal CVT behavior (incorrect for XLE model). System flash/reset performed at one dealership with partial success.
Unintended Acceleration in Parking / Low-Speed Scenarios
Vehicle accelerates suddenly and uncontrollably during low-speed maneuvers such as parking or pulling into a garage, despite the driver pressing the brake pedal. Brake pedal appears ineffective or there is a delay in braking response.
When: While pulling into garage or parking spot; during low-speed maneuvering. At least two incidents reported, one at 14,000 miles.
Symptoms owners cite: Sudden, uncontrolled forward lurch while attempting to park or in garage; Brake pedal ineffective or delayed in stopping vehicle; Vehicle accelerates despite forceful brake pedal application; No warning lights reported
Repairs/costs cited: One incident resulted in vehicle crashing into a workbench; vehicle was driven to dealer post-incident.
Recalls/TSBs owners mention: Manufacturer investigator found no trouble with vehicle and attributed crash to driver error, despite owner's assertion that brake pedal was forcefully pressed and issue was not driver-related.
Electric Motor / Gas Engine Engagement Failure (Hybrid Models)
On hybrid models, the electric motor engages and propels the vehicle forward, but the gas engine fails to engage. This leaves the vehicle stranded or moving only on electric power in situations where full propulsion is needed, such as pulling into traffic or navigating roads.
When: When pulling out of driveway or neighborhood; attempting to merge into traffic or navigate roadways. Described as recurring.
Symptoms owners cite: Electric motor starts and propels car forward initially; Gas engine fails to engage; Vehicle cannot maneuver or accelerate adequately; No error codes displayed
Repairs/costs cited: No repairs documented in narratives.
Recalls/TSBs owners mention: Dealer aware of issue according to owner; however, dealership reportedly fails to return calls or downplays concerns. No documented resolution.
