My Tundra iForce MAX was Toyota saleperson demo truck before I purchased it. Got my truck approx. 2XXX Mileage in late sept. I started noticed transmission vibration while medium acceleration approx. 40 mph in early October. Vibration only occur during transmission warm up. Been attending to 2 dealerships multiple times and they find nothing wrong with my transmission since November 2024. I got Loaner 2024 Tundra iForce recently with same 10 speed transmission, it felt lot smoother and no vibration at all for a whole week before return the loaner. The vibration from my Tundra feels like clutch slippery somewhere from transmission or K0 Clutch. Some time it makes the acceleration feels delay while it was vibrating aka slippery. 2nd problem, I noticed left front tire edge shows sign of start worn out while tire is only have 8k miles on it. Dealership checked the alignment and said nothing found wrong. They recommended me to tire rotation on 5k miles without offer replace tire that is about to show bald on edge. Tire is factory off road package tire aka Falken Wildpeak AT3WA. 3rd problem, during first oil change at 5k miles. I noticed there is oil residue on bottom bell housing between engine and electric motor. Dealership cleaned it and wanted me to come back at 10k miles routine maintenance inspection. Around 6k miles, I took a look at the leak area. Oil came back as seeping. Dealership denied and said there is no leak at this time. Saw the oil residue from their inspection report.
