2016 Lexus ES Problems

The brake actuator and/or brake booster pump assembly failed on my 2016 Lexus ES300h. This is a known issues for this vehicle's braking system and results in a sudden loss of power braking assistance. The failure requires increased pedal pressure and eventually brkaing failure, creating a significant safety hazard and increasing the risk of collision. The dashboard displays multiple warning lights, including Braking Power Low and Brake Override Malfunction. Lexus has acknowledged this defect through an extended warranty and consumer warranty program, but Lexus is alleging my vehicle (despite showing issues prior to 150,000 miles) is now over 150,000 miles and not eligible. I am reporting this because a critical safety component should not have a "timer" on it when it involves primary braking of the vehicle.

The contact owned a 2016 Lexus ES. The contact stated while at a stop sign, the brake pedal was depressed; however, the brakes failed to engage and the vehicle unintentionally accelerated which caused the front driver's side of the vehicle to crash into another vehicle. There was severe cosmetic damage however, no injuries was sustained. The air bags was deployed. No warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the vehicle was totaled. A police report was filed. The manufacturer was not notified of the failure. The failure mileage was approximately 131,000.

In April 2022, the timing cover seal on my 2016 Lexus ES 350 was replaced due to a leak. This was completed under warranty at approximately 84,785 miles. In February 2025, less than three years and roughly 56,000 miles later, I was informed by the same Lexus dealership during a routine service that the exact same issue—leaking from the timing cover—had reoccurred. There were no warning lights, engine performance issues, or visible signs of oil loss leading up to this. During my prior service appointment in December 2024, I was told the car was in excellent condition with no issues. I service my vehicle at every Lexus-recommended interval and maintain a full history of service records. The dealership has confirmed the new timing cover leak but has not been able to explain why the seal failed again. This is a major engine component that should not require a second repair within such a short time frame. I am now being asked to pay a significant portion of a nearly $5,000 repair despite a prior warranty fix, and despite having done nothing to cause or accelerate the failure. Lexus offered a partial goodwill credit, but no root cause has been identified. I am concerned that either poor workmanship or substandard parts contributed to the premature failure, and that it may happen again. Given the cost, critical nature of the part, and the lack of answers, this feels like more than just an isolated incident. I have complete service documentation and before-and-after video footage of the most recent repair. The vehicle is currently in my possession and available for inspection upon request. I purchased a Lexus because I believed in the brand’s commitment to long-term reliability and quality. That confidence has been shaken. I respectfully ask NHTSA to investigate this recurring failure and assess whether this is part of a larger issue.

On May 13, 2026, while traveling at approximately 31 mph under normal driving conditions, a critical right-front suspension or steering component suddenly suffered a catastrophic structural failure on its own. This spontaneous mechanical failure caused the vehicle to immediately and violently veer to the right, rendering the steering ineffective and resulting in an unavoidable collision with two parked vehicles. The vehicle has been determined to be a total loss. Furthermore, during the crash event, the front passenger-side seat-mounted side airbag and side curtain airbags deployed despite the front passenger seat being completely unoccupied. Conversely, the driver's front steering wheel airbag failed to deploy completely during the impact. A corporate inspection by Toyota Motor North America/Engineering Analysis Associates confirmed severe, localized separation of the right front strut, knuckle, tie rod end, brake line, and ABS wiring. Toyota is currently utilizing its own interpretation of the Event Data Recorder (EDR) steering/speed metrics to deny component defect liability, attributing the structural suspension failure to post-crash forces rather than pre-crash causation. I am filing this report to log a potential structural component defect in the 2016 Lexus ES 350 front suspension/steering assembly, as well as an irregular Supplemental Restraint System (SRS) deployment pattern, which presents an unreasonable safety risk to drivers.

The contact owns a 2016 Lexus ES350 equipped with General Tires, Tire Line: ReliaTrek, Tire Size: 225/45/R18, DOT Number: VY4FWJ85. The contact stated that while driving 60 MPH, the vehicle was vibrating abnormally. The contact pulled over and called Roadside Assistance. The Roadside Assistance technician made the contact aware of a blowout of the driver's side rear tire. The contact was shown that the entire sidewall had detached from the tread. The spare tire was installed by Roadside Assistance. The contact stated that the tires had recently been purchased by the previous owner however, the contact was unsure of the failure mileage on the tires. The contact had not taken the vehicle to a dealer or independent mechanic. The failure was not diagnosed nor was the tire replaced. The manufacturer was not made aware of the failure. The approximate vehicle failure mileage was 100,000.
