2011 Toyota Venza Engine Problems

Your 2011 Venza developed a rough running condition and rattling noise, which was diagnosed as a faulty water pump and replaced. However, about 45 days later, the engine stopped running while driving because the oil level was completely empty. The dealership then determined that the engine compressors had failed and the entire engine needed replacement at a cost of $5,500-$9,400. You believe the dealership should have checked for engine compression and oil system issues (like VVT-i oil line failures) when the water pump was replaced, especially given known Toyota issues with these components affecting engine reliability. Resolving this issue may require a complete engine replacement or significant compression system repair.

Around 100,000 miles, your car started making a grinding noise when starting and was consuming oil very quickly. You took it to the dealer multiple times over several months, and they replaced the oil housing and tubing, ran tests, and said it passed—but your car is still burning about 15 quarts of oil every 5,000 miles. You're concerned the engine could stall on the highway when the oil runs out without warning. Addressing this may require further engine diagnostics, a second opinion from another dealer or independent shop, or potential engine repairs if an internal leak or consumption issue is found.
