2017 Lexus IS Complaints

I am unable to shut the engine off to pump fuel into the vehicle. The purge valve has been replaced, that maf sensor has been cleaned the leak detector pump has been changed. The vehicle will shut off and go into low power mode while driving on Highway, the idling is rough. The check engine light will not go off. The code is reading Po171.

The vehicle is experiencing a failure of the dual-zone HVAC system where the passenger side consistently blows hot air while the driver side is set to cold. This indicates a failure of the HVAC blend door actuator (servo motor), which is a known issue for this model year. This failure poses a safety risk as it can prevent proper defrosting and defogging of the windshield during inclement weather, obstructing driver visibility. Also should note While driving, the vehicle becomes excessively loud and behaves as if it is stuck in the wrong gear, accompanied by a significant loss of engine power. An onboard diagnostic alert has indicated a malfunction in the electronic control of the engine throttle or automatic transmission. This 'limp mode' behavior creates a hazardous situation during highway driving or merging, as the vehicle cannot maintain speed or respond to throttle inputs, increasing the risk of a rear-end collision.

I own a 2017 Lexus IS 200t that is experiencing fuel pump failure. Although I checked my VIN and confirmed there are no open recalls listed, the symptoms match the known fuel pump issues affecting other Lexus vehicles from similar model years. The only reason my vehicle is not included is because my VIN falls outside of the specific batch covered by the recall, even though 2016 and 2017 models share the same problem. Because I am experiencing the identical safety concerns reported in the recall—such as potential engine stalling and loss of power—I believe my vehicle should be considered part of the affected group. It is not safe or fair that some 2017 models are excluded based solely on VIN range when the defect clearly exists in other units as well. My vehicle is showing the same failure and should be eligible for the same repair or recall coverage. If you’d like, I can also format this as an email, a letter to Lexus corporate, or a service request message.

I was driving my vehicle and then the entire car shut off going about 50 MPH causing the car to immediately stall. Nothing eventually worked making me have to push my car onto the side of the highway. Replaced the alternator and battery. Eventually got my car scanned and the issue I’m having is a fueling system problem. Did some research and my car 2017 IS350 f sport did eventually have that recall issue. The vehicle was not showing any problems before hand it just happened.

I have been having problems with hard starts, rough idle, engine dying. My vehicle is experiencing all the same reported issues as a recall issued for a fuel pump on my make/model. My VIN however, is not covered under the recall. I've contacted Lexus and they said that if enough people complained that they could make this fall under the recall. It only has problems at idle and upon acceleration. Once a decent speed is reached, I have no problems. This is intermittent. I've also taken it to a Toyota dealership where they kept it for 2-3 days and could not figure out what the problem was, although they witnessed all the issues. I'm marking September as the date of the incident, but this has been ongoing since last year and currently giving issues.
