On several occasions in the previous two months, I have been driving during heavy rain. On the first occasion, while high speed wipers were on, they suddenly stopped working. I slowed down, but was able to get them going again prior to pulling to the shoulder of the highway. I had to switch to the slow wiper speed to get them going. I switched back to the high speed wipers due to heavy rain, and kept stopping each time. It continued this cycle and stayed on after about 15 attempts. Today, on [XXX], I drove down [XXX] from Flint, MI towards Detroit at approximately [XXX]. The wipers again quit working and I had to switch the wiper speed to get it working again while at full highway speed during a deluge of rain and nearly had to stop in a construction zone with no shoulder and heavy traffic, nearly causing a collision until I was able to get the wipers to begin working again. On a previous occasion, I turned them on. When the rain stopped, I was unable to stop the wipers, but was eventually able to stop them by carefully moving the intermittent delay wheel to a position between on and off. It appeared that there may be a short in the wiper circuit. This was a definite safety issue in that my attention was taken away from driving to try to fix the wiper situation. In speaking with my service adviser at Randy Wise Toyota in Grand Blanc, MI, he went out to their lot and tried to duplicate the problem, which he confirmed happened on that same Toyota Tacoma model. I attempted to get this repaired under warranty. Their response was that there was nothing they could do since it appeared to be in the design of the wiper system. My opinion is that this is a serious safety issue which needs to be addressed immediately. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
