What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 Ineos Grenadier, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
Incident Summary: I am reporting a recurring and dangerous failure of the vehicle’s lane-keeping/automated steering system. The vehicle provides unprompted, forceful steering inputs that fight the driver’s control, creating an immediate risk of high-speed collisions. Incident 1 (I-5 North): Traveling at 70 mph in the right-hand lane. Every few minutes, the vehicle initiated an unprompted steer to the left. I had to physically fight the steering wheel to maintain center and avoid a crash. The behavior only ceased when I moved to the left-hand lane. Incident 2 (I-80 East, Reno/Mogul, NV): Traveling at 65 mph in the left-hand lane. The vehicle initiated a sudden, forceful steer to the right, nearly causing a side-swipe collision with an adjacent vehicle. I had to use significant physical force to override the system and prevent an accident. Systemic Failure & Safety Concern: There is currently no way to permanently disable this system in the vehicle settings. Because the system defaults to "ON" upon every ignition cycle, I am forced to drive a vehicle that unpredictably attempts to steer into other lanes or off the road. The inability to permanently opt out of this malfunctioning "safety" feature is a grave concern, as the system itself has become the primary collision hazard.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
