The vehicle is a 2015 Toyota Sequoia with the 5.7L V8 engine and approximately 192,632 miles. The vehicle developed an abnormal internal engine/timing noise, especially when warm. An authorized Toyota dealer inspected the vehicle and diagnosed an internal engine/timing-related condition involving timing chain tensioners, timing chains, chain guides, camshaft gears, lifters, gaskets/resealing, and related labor. The estimated repair cost is approximately $19,716. The concern is safety-related because if the timing chain, tensioners, or related internal engine components fail while the vehicle is being driven, especially at highway speeds, the engine could stall, lose motive power, or become unable to safely continue operating. A sudden loss of motive power in traffic could increase the risk of a crash and put the occupants and other motorists at risk. This is a family vehicle used to transport young children, so the risk is not theoretical or acceptable. The problem has been confirmed by an authorized Toyota dealer. The vehicle and affected components are available for inspection upon request. The vehicle has been consistently maintained per the manufacture's schedule. Separate wear items were already repaired as needed. The dealer’s diagnosis concerns internal engine/timing components consistent with manufacturer defects, not ordinary maintenance items. To my knowledge, the vehicle has not been inspected by the manufacturer, police, insurance representatives, or any agency other than the Toyota dealer. Warning lamps or messages are UNKNOWN. The primary symptom before repair was abnormal internal engine/timing noise. This complaint is being submitted to document a potentially serious internal engine/timing component condition that could affect the vehicle’s ability to safely propel itself if the failure progresses. Thank you for your time and attention to this matter.

What owners say
Toyota had a recall on fuel pumps in 2020 mine was not part of the recall even though mine went bad and had to be replaced in February 2020. Now with another fuel pump recall issued in January 2025 I am also told mine is not part if the recall however I am having issues related to the fuel pump once again causing my engine to stall. Can someone please look into this as I feel my car should be part of that recall for another failing fuel pump. I do have receipt of repair in 2020 by First Class HALT I can provide if needed. My engine is stalling, not cycling fuel properly and has left me stranded. Then other times fires up normally.
On [XXX] while driving our 2011 Toyota Sequoia 4x4 Limited (5.7 iforce non flex fuel) my wife was preparing to stop at a traffic light. Completely unexpected and with no warning, the vehicle started bucking, the engine began making a knocking noise and numerous dashboard lights started flashing. It immediately stalled while attempting to stop, thus, causing a very dangerous situation, losing total control of the brakes and steering, nearly causing a collision with the vehicle in front of her. The vehicle had to be towed from the middle of the road, while in heavy traffic. Eventually it was diagnosed (at my mechanics shop) and determined to be a broken valve spring in cylinder #7. This caused the valve to drop into the cylinder bore, making contact with the piston, known as "catastrophic failure on an 'interference' engine"..I later learned that these DEFECTIVE ($5) valve springs, are used in my meticulously maintained 5.7 Toyota motor,...THE SAME PART NUMBER UNDER RECALL IN SEVERAL LEXUS VEHICLES!! Being that I constantly maintained this vehicle and it being in overall excellent condition, I determined it was less expensive to have the engine replaced over repaired. I spent over $4600 in a used motor with 88k miles, and $5400 in labor for the replacement.. total cost of over $10,000 for a $5 defective part that was only recalled on the Lexus vehicles. I kept the original engine in case I can (eventually) have Toyota Corp do an inspection on it and get some kind of compensation on this dangerous, avoidable, selective vehicle recall. No luck thus far but have pictures, invoices and all documents on this situation that I can provide when requested. I am having difficulty downloading these documents to this site. Thank you very much. [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2020 Toyota Sequoia. The contact stated while driving 70 MPH, the vehicle failed to accelerate as designed, without warning. The contact stated that after driving for several minutes, the vehicle operated normally. The contact stated that on another occasion, the vehicle lost motive power and stalled without warning. The contact was able to pull over to the side of the roadway. The vehicle was taken to the dealer for diagnostic testing however, no failure was found. The manufacturer was not contacted. The failure mileage was 41,000.
Tl* the contact owns a 2007 toyota sequoia. The contact stated that while driving 45 MPH, the vehicle stalled with the check engine warning light flashing on the instrument panel. Due to the failure, excessive force was needed to steer the vehicle to the side of the road as the steering also failed to operate due to the failure. The vehicle was towed to an independent mechanic where the vehicle was diagnosed with a defective spring valve. Neither the manufacturer nor the dealer were notified of the failure. The vehicle was not repaired. The failure mileage was approximately 118,000.
The car doesn't want to start. All lights are on the dashboard. The car runs terribly and stalls at times. The code states the fuel pump needs to be replaced. Fuel pump has been on backorder for 5 weeks. Over 1300 requests for the part in this area alone. Obviously this is a problem with other sequoias as well.
My 2014 toyota sequoia is stalling at low speeds, I.e. When making u turns or slowing up and pressing the gas, there is a 5-7 second delay in the engine responding, this is causing a safety issue when you need to get out on a busy road and you don't have the power needed. I have spent several hundred dollars at the toyota dealership with still no resolution and recently had the spark plugs replaced. I have read on newer models the fuel pumps have had a recall, but at this time not the 2014. Please note for the question below, when did this happen, its been going on now for over a year.
Tl* the contact owns a 2005 toyota sequoia. The contact stated that the vehicle had a sudden loss of power. Also, the vehicle stalled while making left and right turns and various warning indicators illuminated. Initially, the dealer (principle toyota, 7370 winchester rd, memphis, tn 38125, (877) 217-4003) was unable to replicate the failure, so it continued to progress and various warning indicators remained illuminated, the vehicle was taken back to the dealer for diagnostic testing. The manufacturer was notified. The approximate failure mileage was 45,000. *tt
The trac off light and vsc light and ABS light comes on, on the dash. When you make a turn the vehicle looses power and stalls in the road. The steering is all over the road and it doesn't have the stop time as it did.
Tl* the contact owns a 2004 toyota sequoia. While driving 50 MPH, the vehicle stalled without warning. The contact stated that the entire instrument panel warning console illuminated and the brakes shook. The vehicle was diagnosed, but the dealer could not duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure and stated that there was no recall related to the failure. The failure mileage was 57,000.
