There are 1 owner-reported fuel system complaints for the 2015 Lexus ISin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
My car has had issues where the car will either not start, or the car will stall and turn off while I am driving on the road, causing my car to become a hazard for myself in the car, and other cars who have to avoid it being in the middle of the road. This first happened to me 2 years ago and I took it to a mechanic who could not identify the issue because they could not replicate it while it was in the shop. I then took it to the nearest Lexus dealership and after a few days they identified the problem as a malfunctioning High Pressure Fuel Sensor and replaced that part, which I paid for out of pocket. The issue happened again 2 months later and the Lexus dealership replaced this part again. That was 2 years ago, the warranty on that replacement ended after 1 year, and my car had the same issue again where it literally stopped and turned off while driving on the road with no warning whatsoever. No light or indicator came on until the car engine turned off and then the entire dashboard lit up. My car is currently at another Lexus dealership and they are attempting to identify the issue once again. I see that there was a Fuel Pump recall put out for other Toyota / Lexus vehicles for this exact issue, but my specific Model / VIN are not a part of this list. The descriptions and reasoning for the recall describe my exact situation, I would like to see if there is a way I am able to add my Model / VIN to this list to protect myself and others. I do not feel safe driving my vehicle as it can turn off on me at any moment on the road.
