Engine began suddenly running very rough and on the verge of stalling at highway speeds. Car was brought to dealer, who also fixed electric problem , (dark current draining battery). This problem was determined to be small pieces of carbon infiltrating emissions controls, (PCV valve, etc.) High repair cost was due to labor as emission controls/modules were located between engine and firewall. Over 2,000 miles have been accrued since repair without further problems.

2015 Toyota Avalon 4dr Sedan

268-horsepower 3.5L V6 6-speed shiftable automatic FWD

No work performed. Engine randomly hesitates on start, dealership claims it was a bad batch of fuel, threw some additive in and called it a day. This did not fix the issue. 
16100 mi Nothing. Dealership claims they cannot replicate the issue, though I can replicate it. I have recorded video to verify to the dealership that this is an ongoing problem.

26000 mi charcoal canister needed to be replaced. 3 1/2 hr. job. Found out from another dealer that the real reason the light was on was that a mouse had chewed thru the wiring harness. The first dealership should have checked that first thing. I doubt anything was wrong with the canister, be cause the light kept coming on.

Exhaust manifold has design flaw but no recall. Air/fuel sensor Bank 1, sensor 1 fails prematurely. Replace mainfold/sensor for $1800 or sensor for $240 every 20,000'ish miles. I chose the latter. Good now for another few years (I hope) 
34200 mi This is the second time the air-fuel sensor has died. An OEM replacement was used last time and lasted only 1 year. There is a design-flaw in the exhaust manifold. Must be replaced to avoid repeated repairs, but that would cost $1800 :-( UPDATE: May 2017 - 5 years later: No new failures of this part. Perhaps the second replacement done in 2012 will be the last one. Did they fix the sensor design ? (I still haven't replaced the exhaust manifold which was the original Toyota recommendation)

Gas smell in garage on very hot days. Replaced gas cap and seems to have gone away. Finally got around to replacing A/F sensor (for second time - see earlier entries).

(First one lasted only 14 months) UPDATE: May 2017 - 5 years later: No new failures of this part. Perhaps the second replacement done in 2012 will be the last one. Did they fix the sensor design ?
