AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

NHTSA recall #00V200000July 18, 2000875,000 vehicles affected
equipment: mechanical: integrated jack/leveler/stabilizer
Vehicle description: passenger vehicles. These vehicles have jacking instructions which, if followed, could cause the vehicle operator to place the jack on a frame weld when attempting to raise a rear wheel. If the vehicle is jacked up with the jack placed on the frame weld and if the vehicle is free to roll (wheels not blocked or chocked), the jack could yield and the vehicle may drop suddenly.
If this occurs and any portion of the operator's body is under the vehicle, the potential for personal injury exists.
Remedy
Owners will be provided with a revised jack instruction and stowage card and jack warning label, as well as a supplement to the owner guide.
