2008 Lexus RX350Transmission & drivetrainLights

1. Ignition System: While driving the key in the ignition lock came out loose! Exremely frightened and managed to pull the car over to a driveway. But, the car could NOT be stoped using the key fob. Key will not work to stop the engine. Very unusual and unexpected incidence. 2. Lighting system switch: Suddenly the knob of the light switch came out loose with a plastic shaft and will not turn on the light. Very unsafe while driving and it became dark due to storm and rain, and I wanted to turn the headlights for safety. I beleive it is a manufaturing defect and causes severe safety issue.

Dear Sir or Madam. My name is [[redacted]], [[redacted]], [[redacted]] living in [[redacted]]. I bought my 2008 Lexus RX400h car, used, in 2014 at a non-Lexus dealership in the [[redacted]] where I used to live. My Lexus VIN is: [[redacted]]. I've been satisfied with the car..until today. The car had been running smoothly forever, and this morning while I was driving I came to a stop (red light) and the car suddenly shut down completely, including the loss of lights, and the whole dashboard went dark. Other cars...

behind me were honking their horns. I could not even turn on the hazard lights. After 1-2 minutes, all of the lights/warnings started coming on one after the other. I started the car again and run around three different errands without having further issues. I checked online to see if other owners had experienced a similar situation, which is the case. One person said that there had been two recalls in 2011 and 2013, both related to the inverter module inside the hybrid system. Although, I called today a Lexus dealership, [[redacted]], located in [[redacted]], and I was told there are no recalls for the VIN number that I provided. Another owner said she/he went to a Lexus dealer in [[redacted]] and she was told it was a defect in the gutter drainage design and that water gets into the hybrid system. This is a dangerous and potentially catastrophic situation if the vehicle suddenly shuts down on a freeway/highway putting passengers in risk of harm, injury, or death. This is a horrific defect which Lexus should correct immediately with a recall before one of us ends up at the cementery. I am glad to know that organizations such as the NHTSA exist, and I will appreciate very much that immediate action is taken on this matter. Sincerely, [[redacted]].

2010 Lexus RX350Engine & coolingFuel system

I was looking at common problems associated with the make and model of my car. I came across an issue that could possibly cause engine failure. I am unsure if any one has reported it yet. here are the details - Problem overview An VVT-i oil line on the Lexus RX350 is known to burst. This is a very large leak which covers the ground, engine, and undercarriage. If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate. Continued use after these warnings...

will result in complete engine failure due to oil starvation. The line is known to be defective, and a revised part has been issued by Toyota, however, this revised part is known for the same issue. To repair the issue, the line must be replaced, and the engine bay and undercarriage must be cleaned thoroughly. The problem has occured generally around 120k miles. Here is the link to the website that has collected information from 116 users. Requesting you to please check if this a problem that needs a recall? [[redacted]] ely report it.

2007 Lexus RX350Brakes

I am reporting a serious and potentially dangerous braking issue with my 2007 Lexus RX400h. The vehicle currently has approximately 126,296 miles. While driving, the vehicle emits a continuous and intermittent warning beeping sound. At the same time, the braking system becomes unreliable. The brake pedal becomes extremely difficult to press, requiring excessive force, and the vehicle does not respond consistently when braking. In addition, there are instances where the vehicle appears to brake unpredictably or...

inconsistently, which creates a significant safety hazard for myself, passengers, and other drivers on the road. Based on my research, this issue appears to be related to a known defect involving the ABS brake actuator assembly. Lexus previously issued a warranty enhancement program for this component due to internal malfunctions that affect brake pressure and system performance. However, this issue was not issued as a formal recall tied to VIN eligibility. Despite my vehicle being under 150,000 miles, I have been informed that I may be outside the time-based warranty window, and no active recall is listed for my VIN. This defect directly impacts the braking system, which is a critical safety component. Failures in the brake actuator can lead to improper brake pressure, reduced stopping ability, and increased risk of a crash. Given the safety implications and known history of this defect, I believe this issue warrants further investigation and potential recall consideration. I am submitting this complaint to request that the NHTSA review this matter for safety risk and determine whether broader action is necessary to protect consumers.
