Lexus RX fuel pump problems

Filed Oct 31, 2026 · Fuel system · CA

While driving my vehicle on a major road the car suddenly started shaking, all the lights/warnings showed and my speed dropped to 10 miles per hour. I nearly avoided being hit. Had the car towed to a service center who informed me that my code was 20LA01 and my fuel pump was the issue with an active national recall on the part. They told me to tow it to Lexus since it would be covered. Lexus refuses to cover the cost since my VIN is not listed even though my car has the right code , displaying the obvious issues , and agree that is the problem . How do I get my VIN recorded as part of this recall and to help others that might encounter this.

The contact owns a 2022 Lexus RX 350. The contact stated that after refueling, there was an abnormally strong fuel odor coming from the vehicle. The odor was more pronounced while the vehicle was parked in the garage, and the garage was filled with a gasoline odor. There were no warning lights illuminated. The vehicle was taken to the dealer, who diagnosed the vehicle with a failure of the high-pressure fuel pump. The high-pressure fuel pump was replaced; however, the failure persisted. The vehicle was returned to the dealer approximately 3 weeks later. The contact stated that the battery and charcoal filter were replaced; however, the failure persisted. The vehicle was returned to the dealer a third time, at which time the dealer had not performed a repair. The manufacturer was informed of the failure, and a case was filed.

The fuel pump sensor electrically shorted. The assembly failed. (tube assembly, fuel suction w/ pump and gage), gasket, fuel suction tube set. It is available for inspection. The car could stall at any time because the fuel pump sensor cannot accurately determine the fuel level or how much fuel is being injected into the engine. There was a warning light. Lexus covered two other fuel pump safety issues for this make and model (2018 RX 450h), one under a manufacturer recall and one through a customer support program. This is a THIRD defect with the fuel pumps on these vehicles for which Lexus has NOT offered coverage or notified its customers.

My car has an oil leak from the timing chain cover gasket that was discovered by an independent mechanic at 37,465 miles. The dealer confirmed the leak on June 14, 2024 during a recall replacement of the fuel pump. The repair is very expensive and the car is no longer under warranty. This is the second occurrence of this same issue. The first occurred in April 2021 at 24,192 miles and was repaired by the dealer under warranty. There were no warning lamps or messages of the problem but there was oil on the ground where I park. The car is available for inspection. An internet search confirms that this is a known and common problem with the Lexus RX350 (and specifically the 2017 model) for many owners with some occurring more than once as in my case.

My vehicle has an intermittent check engine light along with an ICS malfunction code that pops up on the dashboard. The car doesn’t want to turn on after every gas fill up. After taking my car to a couple of independent shops, they determined that the issue with the car was the high pressure fuel pump. The suggested, I take it to the dealer as there was TSB bulletin on it. Furthermore I still had the letter from Lexus stating the issue. The local dealership refused to do the work and suggested other work after charging a huge amount for the car inspection. Lexus Corp wouldn’t help on the matter. There are 4 other complaints on this same issue and the dealers and the Plexus Corp are getting away with not calling this an actual recall because the government hasn’t stepped in.

I purchased a 2017 Lexus Rx 450h Fsport last year at Carmax. About 6 months ago, I noticed that every time I pressed the brakes, there was a chirping sound. I figured it could be dust in the calipers. As the months went by, the chirping sound has gotten louder and now it affected the parking brakes. I researched this problem and many people online have also complained that they are hearing this Chirping sound or what the Dealer calls a "Brake Squawking" sound. I received a letter from Lexus saying to bring my vehicle in for a possible Brake Booster and Fuel pump failure. So I brought my car to the dealership. Since it's there I complained about the chirping sounds that it's making every time I step on the brakes and when the parking brake is applied. I told the Advisor at Lexus that a lot of people online have also complained about this problem and it should be a "Recall". He said that it's not a Recall. To make the story short, the Dealership didn't find anything wrong with the Brake Booster and the Fuel pump. What's causing the Chirping or Squawking sounds was the "Brake Actuator". I was quoted $4,327 to have these parts replaced because my Rx was already past the 50,000 miles warranty. I brought my Rx to the Dealership at 55,483 miles. It was a great thing that we purchased the extended warranty at Carmax called the Max Care which I only had to pay a $100 co-pay. Amazing! It took about 2 days to have this completed. Now, the chirping sound has disappeared when I press the brakes and when the parking brake is applied. I truly believe that this should be a Recall by Lexus and be covered. It shouldn't matter how many miles the customer has. This is a safety issue. The brake actuator shouldn't fail this soon. I have a 2007 Lexus GS350 with 225,000 plus miles and I never replaced the Brake Actuator. I don't know if even has one. The bottom line is when I press the brakes on that car, there were never any chirping sounds.

Contact states they were sitting in DRIVE, with their foot on the brake. When the contact took their foot off the brake, they began to let the vehicle coast to about 5 MPH. Then, the vehicle lunged forward unexpectedly to about 25 MPH, when it collided with a rock. The vehicle had previously spent over 10 days in different dealerships to diagnose issues related to the engine running rough, the car stalling out, and the vehicle driving erratically and lunging forward. The contact only began to have issues with the vehicle after the federal safety agency Denso Fuel Pump Recall. A year after the contact took delivery of the vehicle, the remedy was done. The dealership stated they had completed the remedy properly, but because of parts shortages they only MODIFIED the fuel pump, but that TMNA said this is a valid remedy. After further investigation, the remedy protocol which they followed did not match the one the manufacturer assured the federal safety agency they would follow, and there was no amended the federal safety agency remedy. Then, the manufacturer denied they told the dealership that the protocol they followed was a valid remedy. About 10 minutes after leaving the dealership the contact returned and stated the vehicle was running rough and driving erratically. The dealership told the contact that it was completely normal and that the vehicle just needs to re-learn their driving style. The contact had issues with the vehicle, including the illumination of warning lights, and the dealership cannot remedy the issue (refusing to replace/repair the fuel pump).

My car stalled in the middle of an intersection. It had to be towed to the Lexus dealer, where it was determined to be a fuel pump malfunction. My car was not subject to the fuel pump recall but it should have been.
