Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“We have a Toyota Sequoia, the problems are the 4 wheel drive is not operating all the time. It does not engage, when it does sometimes it does not stay in 4 wheel drive. One example is when my wife had six friends in the vehicle the 4 wheel drive did not stay engaged and the vehicle skid control made the engine loose power so she slid backwards down a hill. No one would ride in our 4 wheel drive again. The vehicle skid control activates at radom on dry pavement. The skid control makes the engine loose power while in traffic. …”

“After meeting with district parts and service operations manager steve carlson on 9/23/02. I''ve come to the conclusion that Toyota will not fix the problem I have with the smell coming from my 2001 Sequoia. First of all, I had to call the dealership at 10:30 in morning to make sure that the manager was going to be there. Second is that I got the run around about I should try a ''for fun and giggles'' by not running my recycling mode when driving with the A/C on. Third is that when the front windows are open I''m still getting the worst smell of exhaust coming from the rear. …”

“The front braking system on 2001 Sequoia was replaced and upgraded. The brake jobs were performed at the following mileages: 15k, 25k, 30k, 55k, and 74k miles. The left wheel rattled over the rough road, the rear left strut made a noise when going over bumps due to a broken shock, and the engine light had come on.”

“2001 Toyota Sequoia. When I shifted from reverse to drive the engine roared to a fully racing engine and accelerated forward. Hard braking could not slow the vehicle and it hit the back of a 2004 honda mini-van that was parked, doing extensive damage but causing no injuries.”

“My 2001 Toyota Sequoia had an issue with check engine light at approximately 77,000 miles. It pulled the p0155 code that indicated failure of oxygen sensor. Toyota had at least two technical service bulletins on the issue showing this problem as widely known. What is more, on tundra vehicles (that have the same engine)Toyota recognized the issue by extending the warranty on sensors and on that specific code up to 90000 miles. The repairs cost was almost $340, pulling the code (5 min) and replacing the sensor (15 min) was charged at 2 hrs of labor. …”
