LEXUS GS

FUEL SYSTEM, GASOLINE:DELIVERY

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006-2009 LEXUS IS AND MODEL YEAR 2006-2007 LEXUS GS VEHICLES. DUE TO INSUFFICIENT TIGHTENING OF THE FUEL PRESSURE SENSOR CONNECTED TO AN ENGINE FUEL DELIVERY PIPE WITH NICKEL PHOSPHORUS PLATING, THERE IS A POSSIBILITY THAT, OVER TIME, THE PRESSURE SENSOR COULD LOOSEN. IF LOOSENING OCCURS, FUEL COULD LEAK PAST A GASKET USED IN THE CONNECTION BETWEEN THE SENSOR AND THE PIPE AND THROUGH THE THREADED PORTION OF THE SENSOR.

Risk: FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.

STEERING

Car keeps pulling to the right at high speed, above 40 mph. Car has been to alignment service and all tires inflated properly. This happens on every trip. Cannot diagnostic the root cause. Suspecting the Steering Rack is the issue.

SERVICE BRAKES, HYDRAULIC

The contact owns a 2011 Lexus GS460. The contact stated that while operating the vehicle, the message "Hydraulic Brake Sensor Fault" remained displayed. Additionally, while depressing the brake pedal, the vehicle experienced severe shaking and vibration. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 149,000. The VIN was not available.

SERVICE BRAKES

Brake actuator or booster accumulator, always has been failing on Toyota/lexus hybrids, they need to do another bulletin or TSD because the malfunction is unsafe and many drivers are reporting it

ENGINE

I started my car in the morning and when I started the engine it was an instant extreme rough idle with the engine light and traction control light blinking on my dashboard and the engine cuts out on its own. I have my car at a Toyota dealership since it’s closer than the Lexus dealership and they have ran an extensive testing diagnostic on my car resulting in a valve stuck open and a valve spring fell out. I have kept up the regular maintenance on my car, like every 5,000 miles fully synthetic oil changes, premium gas, regularly checking for recalls, always checking my fluids, correct tires and tire pressure, and I have in no way misused my car since it’s the only car I have to drive. I found that Lexus had a recall on the GS 350 for the 2007 to 2011 years for the problem I’m currently dealing with. In 2012 Lexus did not make a GS 350 but 2013 they were offered again and I feel like they didn’t resolve the engine problem before putting out the new production, at least for the 2013 year. Now as my car sits I have to pay $9,200 to fix the problem and I don’t have that type of money. I would have to sell my house to pay for my car to get fixed. Luckily the car didn’t stop running while I had my family in the car. I don’t feel that I did anything wrong to make the internal engine have a valve issue. This car should still be running at 148,100 miles.

STEERING

I am experiencing a persistent and potentially hazardous steering issue with my 2016 Lexus GS 350 AWD (Luxury Package). At highway speeds (typically 60 mph and above), the steering exhibits a distinct "sticky" or "notchy" sensation around the center position. Specifically, the steering wheel resists small corrective inputs when driving straight and appears to "stick" in place before releasing and allowing directional change. This results in delayed response when attempting to maintain lane position and requires greater-than-normal force to overcome the initial resistance. The condition becomes most noticeable after continuous driving at highway speeds and compromises the vehicle’s ability to respond predictably in situations requiring quick or fine steering adjustments. The issue does not trigger any warning lights or diagnostic codes, and it persists despite the installation of new tires and a professional alignment. Due to the impact this issue has on steering precision and overall highway safety, I am requesting NHTSA review this concern as a potential defect. Lexus has not issued a recall for this problem, and it poses a risk to safe vehicle operation at high speeds.
