I have a 2012 Tundra Crewmax Limited Edition. It has 10,393 miles on it. After I had the oil changed at 5k I noticed a random clicking noise when I pressed the accelerator and then again when I let off. Then I noticed it would do it randomly. It doesn't matter what time of day or night. It does not matter if the AC is on or if ANYTHING is on or off. Speed is not a factor. It clicks at any speed from 10-95 mph. This relay just turns on and off at random. I have taken it to two dealerships and neither could replicate the problem until last night. Toyota is claiming this may be a "Tundra" thing and there is nothing that can be done. Does anyone know what this may be? It is defiantly a relay turning on and turning off. Does anyone else have this problem? I only have about 1600 miles to try to fix it or claim lemon. Any help or advice would be VERY helpful. Please help!
