Toyota Highlander power steering loss problems

Filed Aug 27, 2026 · Engine · CO

My 2017 Toyota Highlander, VIN [XXX], has just under 85,000 miles. I was notified at the dealership (Stevinson Toyota in Lakewood Colorado) who inspected the vehicle yesterday that the vehicle has developed a timing cover oil leak on the passenger side. After further research I learned this is caused by premature failure of the factory applied FIPG sealant at the timing cover’s T junction. This is well documented as a known, widespread defect in the V6 engine used across multiple Toyota and Lexus models between 2014 and 2019. This failure is not due to wear, neglect, or misuse. It is the result of a documented manufacturing flaw that requires full engine removal and carries an extremely high repair cost — a burden that should not fall on customers when the underlying cause is a defective sealant application at the time of manufacturing of the vehicle. I was quoted $5400. I am deeply concerned that Toyota has not issued a recall for this problem, despite its prevalence and the clear safety risks it presents. This leak is not merely a “durability issue.” It has legitimate and serious safety implications, including: •The potential for engine fire due to oil contacting hot components •Serpentine belt failure, which can cause sudden loss of power steering, alternator function, and vehicle control •Additional engine damage if the leak worsens •The possibility of the vehicle breaking down in unsafe or remote conditions Any of these outcomes pose a real safety hazard to drivers, passengers, and others on the road. Toyota’s decision not to address this known defect through a recall is extremely disappointing. I have reached out to Brand Engagement and was turned down by a gal named [XXX]. I then escalated the issue and was again turned down by a gal named [XXX]. I firmly believe Toyota should have issued a recall for this known issue costing consumers $5400 to repair a safety issue due to what is documented as a manufacturing defect.

The engine stalled because the fuel pump is failing. We have found that many 2017 Toyota Highlanders have had the fuel pump recalled for this exact issue, yet our VIN is not included in this recall. We experienced the exact issue the recall was issued for stalling while driving. Issue on July 24, 2027: The engine stalled while driving on the highway at high speed and lost power steering, creating a major safety issue. We had our vehicle towed to a car care center. The car care center identified diagnostic codes related to low pressure fuel system pressure, engine stall history, etc. but cannot reproduce the issue. After checking multiple systems, he believes the issue is a failing fuel pump. Background: Over the past 6 months, we have had problems with the check engine light turning on. On multiple occasions, we have brought the car to get diagnosed and the reading has consistently been fuel pressure codes. Each time we get the car diagnosed, the technician could not reproduce the issues and cleared the codes without resolution.

[XXX] battery light appeared on dash. [XXX] on my way to Limestone service station 399 Danbury rd Ridgefield ct ph203-438-8028 a warning appeared on dash stating i will lose steering.Luckily I managed to pull into a parking lot and lost all ability to steer. Thank God i was not on the highway and was not in a catastrophic accident.The dashboard went blank. The engine stayed on as I called Limestone and was told I needed to be towed..As I was calling Allstate for a tow the dashboard came back on and so did the steering. I drove to Limestone. After checking everything I was told they didn't find any codes and there must be a glitch in the system. Battery good, alternator good, serpentine belt good. We also found a recall the federal safety agency campaign number15V144000 for unexpected loss of electric power steering increasing the risk of a crash for 2015 Toyota Highlander. Jan2 2026 i drove to Brookfield Ct Toyota and was informed by a very helpful service manager Katelyn Hadden that Unbelievably my Vin number was not included in this recall and to come back when it happens again I am a [XXX] grandfather who takes his grandchildren everywhere and will not put their lives in danger in this car until this problem is fixed. I was told by Limestone to stay local and come back when it happens again. I would sincerely appreciate any help in correcting this defect.

Car shut down multiple times while driving. Car lost steering and all power then somehow came back to life without me touching anything. It’s as if the car decides to shut down when All Wheel Drive kicks in. First the entertainment system shuts down and then the entire car shuts down.

I have a power steering warning light. Steering is harder than normal. I believe this vehicle is having the same power steering problem that Toyota Tundra and sequoias are having. I want it to be recalled and paid for by the manafacturer. This is ridiculous a well maintained vehicle.

When the vehicle was ~1.5 years old following its 10,000 mile maintenance, substantial thumping generated from the rear of the vehicle. Each time, the dealership attempted to resolve the problem finding issues with struts; however, it only went away in late March after having the vehicle in the shop for weeks at a time on 5 different occasions Nov 2018 - Mar 2019. I engaged Toyota HQ (800‑331‑4331) - filing report #1901092572 - requesting an exchange of the vehicle. This was denied and I was offered a 8 year warranty. *Due to COVID, I rarely drove this vehicle through 2020 and most of 2021, where to date, I have only ~34,000 miles on the vehicle. -On 21 Oct 2021, my wife was stopped at a gas station and attempted to start the vehicle. The vehicle would not start and the following lights came on without previous warning: 1)Braking Power Low, 2)Maintenance needed soon, & 3)Orange yellow triangle lit up with exclamation mark. My wife was stranded for 3 hours and the vehicle had to be towed. The dealership informed me that Toyota installed a generic battery into the vehicle (when being sold) that was only to have 4-5 years of life; however, my concern was that this vehicle had just completed maintenance and there was no warning of this upcoming issue. When repaired, I had to pay for the name brand (True Start) battery. -On 16 Jan 2022, after having driven the Highlander for 25 minutes, I started the engine while in a parking lot. While moving forward and the engine still going, the brakes and power steering went out. On the dashboard, the same lights that came on in Oct 2021, did so again. I had to let the vehicle coast (having no control) with my wife and child in the car through the parking lot. It came to a stop at the concrete parking curb stop at a store front. Toyota stated that since there was no check engine light that there was no code and they could not duplicate the problem. The vehicle was sent back to me with no resolution or explanation.

I was at a stop sign in my 2020 highlander waiting to turn left onto a busy road. Upon turning left onto pa state highway 999, the highlander engine turned off and the steering wheel was "locked" into a left position. This caused the car to continue turning into the opposing left lane resulting in a head-on collision with an on-coming car. With the engine turned off there was no power steering, no brakes, and no way to unlock the steering wheel. The collision caused my car to bounce back and slowly free roll back to the stop sign as though I never entered the roadway.

While driving, we (multiple drivers) experience intermittent loss of power steering at slow to moderate speeds (below 30 MPH). We have checked the fluids and all looks good. The mechanic cannot pinpoint the issue and I've noted that multiple people on the internet have experienced the same issue. The issue occurs very sporadically and may go days without recurrence. It has occurred during turns around the corner as well as during lane changes.
