2012 Toyota Tundra: sudden loss of power

Filed Jul 26, 2023 · Steering, Suspension · CA

My power steering gear blew its seal on the passenger side losing all power steering fluid and almost making me crash into a car next to me, and Toyota refuses to cover it stating that I hadn't had the steering gear replaced prior to whenever their dates were this is clearly faulty equipment and faulty machine work on the steering gear itself. why won't Toyota cover it? I tried contacting One Toyota and Downtown Toyota here in Oakland California and they told me that they wanted $250 to inspect my vehicle and that I would definitely have to pay for it because my vehicle was not under recall it states it is a recall if you look it up.It is worded recall if they're not going to cover it sounds like they're trying to back out of covering it until someone gets seriously hurt or killed like I almost did, I will never buy another Toyota again as long as I live because clearly they don't care about the faulty equipment on their vehicles that's going to hurt or kill someone. All they care about is the mighty dollar and that's just wrong. Safety has gone rite the window and if anyone reading this is thinking about buying a Toyota, I would seriously think twice.

The contact owns a 2012 Toyota Tundra. The contact stated that while plowing his driveway, there was an abnormal burning odor detected. The vehicle suddenly lost power. There were no warning lights illuminated. The vehicle was towed to the local dealer where it was diagnosed and determined that oil was needed. The mechanic became aware that oil was dripping through a small crack on the cam shaft on the right cylinder bank onto the exhaust manifold. The contact was informed that the engine wiring harness was burned. The mechanic recommended that the engine and transfer case be replaced. The vehicle was not repaired. The manufacturer was contacted, and the contact was informed after an investigation, that there was no evidence of a defect. The claim was denied. There was no additional assistance provided. The approximate failure mileage 175,000.

2012 tundra 4.6 v8 my truck will go into limp mode and the 4lo light flashes, check engine, and trac off lights were all on. Almost complete lose of power will happen. In traffic I end up blocking ever vehicle behind me, because the truck will not reach the speed limit. If there is a hill then the truck barely moves going up the hill. After looking online I saw it's a pretty common problem on toyota with the secondary air injection pump seizing. I checked it with the code reader at a local shop and the guy confirmed it, code p2240 "air injection switching valve stuck open bank 1." he told me he used to work for toyota and knew there was the extended repair on this issue but couldn't recall the specifics. I went into toyota and unfortunately they will not cover it for my truck after they ran my VIN number. It seems like a lot of tundras with the 5.7l motor are covered but the 4.6l motors are not. I was informed by toyota that in the future it might be covered.

A light came on and it started losing power. Took it to the shop and was told it was bad gas. I put the cleaner in it and it didn't fix it. I had some buddies tell me to unplug my battery because it sounded like a safety feature. So I did. The light went off and the truck acted right for a few miles then started doing the same thing. Vehicle was in motion on the highway. My buddies referred to it as a "limp mode" or something like that. I was afraid to have it worked on because I was told if there was a recall the manufacturer wouldn't be liable.

* ongoing manufacture defect / safety concern with 2012 toyota tundra 4.6. Code p2440, secondary air injection. Bank one open.---check engine / trac off lights / engine in "limp mode" * documented recurring incidents on 4-2-19 and again on 10-12-19 after costly out of pocket repair. * my 2012 toyota tundra 4.6 motor double cab has experienced the air injection pump failure twice in a six month period. This failure is a safety hazard leading to loss of power and vehicle control. The first occurrence was after a 2,000 mile trip. Driving downhill the dash lights (check engine / trac off) came at highway speed and immediately vehicle power reduced as we tried to power up the next hill. We were able to avoid being run over by following vehicles by pulling off the road, and limped to the nearest mechanic shop. Contacted 3 dealers and toyota corporate with no positive outcome. All parties acknowledge the ongoing defect but will not pay or offer a solution to end the problem. Paid out of pocket for expensive repair. The 2nd occurrence six months later found us again unable to reach or maintain safe highway speeds. Avoid dangerous highway situations, or ability to climb hills. Both instances occurred without warning. * this emission control defect that toyota has known about since the 2007 models. They even extended the warranty through the 2011 model year. Toyota also claims the problem is neither drive-train nor emissions related. After many attempts at the dealer and corporate level, toyota refuses to extend repairs for this well documented defect beyond the 2011 model. Toyota suggests that when enough complaints are recorded, they will extend the warranty on newer models. The lack of support from dealers and corporate toyota is alarming. The repair out of pocket is expensive (from $500 for a temporary repair to $4000 for a replacement from the dealer.)

The secondary air injection system has failed. It is a common problem on tundras. Power loss occurs while driving and the vehicle cant get over 45mph.

Check engine light and trac control lights came on around 72,000 miles. Truck started to be sluggish and lose power. The truck is in a constant 'limp' mode and fails to properly accelerate. It is definitely a safety issue as it causes unsafe conditions when trying to accelerate into a traffic lane. Took it to dealer and it is an issue with the secondary air injection valves and pumps. Dealer quoted me $2184.25 to fix. Not currently covered under warranty. Toyota has addressed this issue with other years and models but for some reason has excluded the 2012 tundra. I have contacted toyota on multiple occasions and they refer me to the federal safety agency to file a complaint. Same issues reported for the 2012 toyota tundra reference the federal safety agency id numbers: 11129958 11129497 11128204 11109923 11104774 11076034 11075528 11065298 11002406 10994136 10926200 10567001 10489030 how many complaints have to be filed before toyota corrects the issue?

My truck is a 2012 toyota tundra 4x4 limited. It has 100,000 miles on it. I typically only drive it on the weekends. I was driving and made a turn, all of a sudden I lost power steering. The accordion boot on the passenger side was full of power steering fluid. It blew a seal on the steering rod. The whole rack and pinion had to be replaced. 18 hour labor job, and with parts $3000.00. I almost got into a accident because I couldn't turn it. You have to drop the engine assembly to change it that's why it cost so much. This has to be a factory decfect. Any input?

Lost power steering . Mechanic says need rack and pump replaced

I experienced an extreme power loss which made it very dangerous to drive. When bringing to the dealership they informed me that the secondary air intake system needed to be replaced at a cost of $4,000. Upon researching I found that this problem has occurred on similar vehicles dating back to 2007. A recall and replacement was issued for all effected vehicles from 2007-2010. It appears that the problem continues after that date but not enough customers have complained or experienced the problem yet.
