2012 Tundra defective air valves causing limp mode
2012 Toyota Tundra Tundra 4dr Double Cab 4WD SB (4.6L 8cyl 6A)
I purchased a truck from Germain Toyota, a 2012 Tundra (4.6L). I recently brought the truck back to this dealership when the check engine light came on, and it began losing acceleration while driving it. The truck received a diagnosis from them for $130. It was diagnosed with a p2440 code. Germain said it can be fixed for a repair cost of $2800-$3000. They said air injection valve … bank was stuck, has debris and possible water intrusion. Toyota said the truck can go into limp mode as a result which causes the truck to not shift correctly and loss of acceleration. This nearly caused an accident. I was changing a lane in heavy traffic and suddenly there was no acceleration. It seemed like the truck wasn't shifting into gears correctly. First I thought the transmission was failing. Toyota issued a recall on the 2007-2010 Tundras and Tacomas due to the defective air valves/air pumps, extending the mileage on these years to 10yr/150k. Then extended same in 2011 but stopped there. The valves and pumps are made out of some cheap alloy, causing them to corrode easily and the system allows water to get into them. The repair parts offered for the repair apparently are made of the same metal so replacing then will probably only get you more time before they go bad again. The truck has under 100k miles on it. I've always taken great care of the truck and have taken it into a Toyota dealer for all scheduled maintenance dates. Germain Toyota said it was out of warranty by about 5 months. Germain Toyota was helpless to do anything other than repair it for the insane repair cost. They didn't know why the warranty/recall was not extended to the 2012. Seems there are alot of other 2012 tundra owners with this problem as well so I'm not alone. Toyota should own up to their defective parts and Germain Toyota should have some solutions other than offering to reinstall defective parts for a lot of money. I doubt I will buy another vehicle from Toyota again.
