2011 Toyota Sequoia Engine Problems

Your 5.7-liter engine has a faulty sealant on the camshaft tower that leaks oil toward the cabin. Because the engine is tilted back, the oil drips onto the heat shield and then onto the exhaust pipe, causing smoke that enters the cabin and produces engine fumes while driving or parked. This oil-on-exhaust condition creates a serious fire risk, and the repair costs over $3,000 and involves replacing the camshaft tower sealant with a newer, improved design.

Your vehicle's air pump has failed and needs replacement along with the air pump driver module, which the dealer estimates will cost $2,643 before taxes. The dealer suspects water may have gotten into the system and caused the failure. Repairs will involve replacing both the air pump and its electronic control module.

Your Sequoia has a slow oil leak coming from the front passenger side of the engine, near the exhaust manifold. The dealer identified it as a leaking camshaft oil seal and is offering to repair it. You're concerned about potential reliability issues after the engine work, especially on a car that's only 6 weeks old. The fix will involve disassembling part of the engine to replace the faulty seal.
