Started car and smoke began pouring from the exhaust while stationary. Checked oil level and found to be within normal range. When driving, car was sluggish under acceleration with intermittent smoke. Took car to san marcos Toyota and they found the engine to be sludged and require an overhaul of the engine ($4900) or replacement of the engine ($6900). The vehicle had only 140,000 miles. We ended up having an independent mechanic overhaul/cleanup the top side of engine for $4000. I have the estimates and receipts for the work if needed. I have researched on-line and found many other Avalon owners who have had the same problem. I am filing this complaint in hope that Toyota will acknowledge the poor engineering of this v6 engine and issue a recall and reimburse their customers who have experience this engine failure.
I was driving my 2006 Toyota Avalon limited when the oil line apparently let go spewing oil all over the engine causing it to smoke. All the oil drained from the engine as a result, creating an environmental hazard. The Toyota dealer that repaired the line mentioned that there was a bulletin from Toyota alerting dealers to the problem but it is not a recall. A review of edmunds and other websites shows a long list of complaints regarding this specific engine failure.
