Vsa Warning Light On Problems of Toyota Avalon

While driving westbound on the muskogee turnpike (hwy 351), at mile marker 20, the cruise control shut off, vehicle stability icon came on, check engine light began flashing. The car also lost power and ran rough. Pulled over, shut off vehicle. After restarting, the car ran fine. This has happened twice, October 3rd and October 17th in 2016. This vehicle is equipped with a keyless remote. Additionally, this happened next to a cell phone tower on the north side of the highway. It does not occur while travelling the opposite direction on the highway.

I was driving my 2007 Toyota Avalon on 3/23/13 when the check engine light, traction control light, and stability control light all came on. I immediately went to a local napa store and discussed the error/s (found on my vehicle dash) with one of the sales assistants. . The sales assistant then went out to my car and interfaced his "black box" with my automobile computer and an error code p 2197 showed up. As it turns out this error code is a faulty oxygen sensor in bank two of my right exhaust manifold. The napa store did not have the oxygen sensor in stock however, as a favor to me they reset the computer and I regained use of my traction control,stability control, and elimination of the check engine light. After further research and verification from an independent garage it appears that Toyota has a technical service bulletin on this issue. The technical bulletin is t-sb-0114-08. It applies to 2005-2007 Avalon's and 2007-2008 camry's. The TSB states that the corrective action should include replacing both exhaust manifold oxygen sensors as well as the right exhaust manifold and gaskets to the tune of approximately $1,800. 00. This is quite evidently an emission issue impacting the safety (no traction control and no stability control) of passengers in the aforementioned vehicles. It is also quite evident that this defective design puts the repair cost right on the back of the consumer. Who has ever heard of replacing an exhaust manifold.
