Toyota is expanding a recall of vehicles due to engine issues, with the number of affected vehicles reported to be over 127,000. The recall appears to involve certain trucks and SUVs, including the Toyota Tundra and Lexus models, and is related to problems with a twin-turbo V6 engine. However, there is some uncertainty about the total number of vehicles affected, with one report suggesting the recall could be larger, and another indicating a smaller number of vehicles are affected in Canada.
