- Uknown: 2023 RX 500H Performance hesitates or stalls when gas is applied to accelerate. When vehicle final start moving after 2-4 seconds, engine revs really high. This is believed to be an issue in the power train and specifically Transaxle issues and ECU programming issues. More on this issue can be found on Lexus service bulletin Record ID #4807268. Yes, vehicle is available for inspection. - Yes, with the vehicle stalling out in cross traffic, it has almost caused me, my wife and child to get t-boned on multiple instances. Lexus corporate and the Lexus dealer had been made aware of this concern on multiple occasions. - No, Dealer has not been able to reproduce after multiple reviews. I do have video proof of the car doing this taken after final attempt for Lexus to review. This video has been sent to Lexus corporate and Lexus Dealer. - Vehicle has been inspected by Lexus dealership as a representative of Lexus corporate. My Dealer has looked at it multiple times and can never duplicate and will not help. I worked with Lexus directly and also were not able to help. Lexus corporate has now turned my case over to their Lemon Law department for review on 7/8/24 due to this issue and many more issues with car. I provided requested information to Lexus Corporate Lemon department on 8/12/24 and have not hear back as of 10/24/24. - Unknown: Issue occurs few time a week since purchased the car on 2/4/2023, but do not recall first experience. Issue occurs more after the car has been sitting for a while on a hot day or not drove in a few days, and will stall out mostly on a left hand turn. The issue feels like the battery is dead and the gas engine has to take over for it causing a lag. When the engine does finally take over it seems to rev really high too. After it does it once or in some cases twice at the beginning of the drive it is typically okay the rest of the drive.

LEXUS claims the car run 27miles per gallon. But the actual miles I got only 22.1 miles after owning it for a year . THIS IS A BIG LIE. Please take appropriate action!

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2023 Lexus RX 350h verdict →
