7 complaints about the 2020 Lexus IS

Newest first, as filed with NHTSA by owners.

Fuel system

Component or System Failure: The low-pressure in-tank fuel pump assembly and integrated fuel level sending unit failed. While driving, the vehicle suffered sudden fuel starvation and lost all motive power. The dealership verified that the car ran out of gas because the fuel level sending unit - which is mechanically integrated into the in-tank fuel pump module assembly - failed and transmitted completely incorrect levels to the dashboard. The component remains intact at the dealership and is available for inspection. ...

Safety Risk: My safety was put at extreme risk. At 7:30 PM in pitch-black conditions, I was traveling at 60 mph on the interstate when the engine suddenly died. Because the dashboard gauge falsely indicated a half-tank of fuel, I had zero warning. I had to desperately coast a dying vehicle across dark, active highway lanes toward an exit. I could not make the exit and was forced onto the shoulder, stopping dangerously close to active traffic. Stranding a powerless vehicle on a dark, high-speed interstate shoulder leaves occupants highly vulnerable to a catastrophic rear-end collision. Warning Signs & Symptoms: There were absolutely no advanced warning lamps, low fuel lights, or check engine messages prior to the failure. The dashboard gauge actively misled me by showing a half tank of gas. The vehicle gave zero indication of an issue until it suddenly sputtered and lost acceleration at high speed. The car then shut itself off completely on the roadside. No dash indicators illuminated until after the vehicle had died and a restart was attempted, at which point the check engine light came on.

While I was driving, my sunroof on the top exploded. There was no rock impact, no external or internal impact. I called Lexus and they told me it's not covered. The Lexus representative said to submit a claim with triple A cus it'll be at least 5k to take out everything and replace it. They won't fix it themselves.

I am filing this updated complaint to supplement my prior complaint (NHTSA ID No. [redacted], filed January 27, 2026) regarding a recurring, safety-critical engine defect in my 2020 Lexus IS300 RWD, 8AR-FTS engine. DEFECT: Three documented misfire events over seven weeks. The second (12/11/2025) and third (1/17/2026) each involved a temporary stall in active traffic requiring immediate evasive action. All events involved flashing MIL, reduced engine power, shaking, and abrupt deceleration. DIAGNOSIS: Authorized...

Lexus dealership - following 34-day retention with Lexus Technical Assistance (TAC Case [redacted]) and personal on-site inspection by a Lexus Field Technical Engineer - confirmed worn intake valve guide on Cylinder 3. Repair estimate: $10,355.61 subtotal per Service Bulletin L-SB-0007-21 ($10,671.72 total incl. shop supplies and tax). Estimate cites L-SB-0007-21 without mileage qualification, confirming technical applicability. TSB PATTERN - NO RECALL: Lexus has issued multiple TSBs on the 8AR-FTS engine: L-SB-0153-17 (September 2017) and L-SB-0007-21 (March 2021, revised April 17 and July 2, 2024), covering 2015-2024 model year vehicles - progressively widening applicability over three years. Both 2024 revisions occurred during the active warranty period. No recall has been issued and this consumer received no notification of any kind. A TSB is an internal dealer communication - not consumer notification. A CPO purchaser relying on Lexus's representations of comprehensive inspection and rigorous certification has a reasonable right to assume known defects were addressed, without searching technical databases. MANUFACTURER RESPONSE: Lexus declined to authorize repair under warranty or as goodwill and declined to confirm authorization in writing. REQUEST: Please investigate whether the pattern of multiple TSBs covering progressively wider applicability - with no recall despite safety-critical symptoms - warrants a formal investigation and escalation to a safety recall.

Engine & coolingFuel system

This vehicle has a recurring, safety-critical defect involving intermittent engine misfires, flashing MILs, reduced engine power, sudden loss of acceleration, and noticeable engine shaking. Despite multiple repair attempts and extended diagnostics by a dealership, with manufacturer technical assistance, the defect continues. The defect has repeatedly caused the vehicle to stall and lose propulsion while driving, creating a serious hazard. Documented events include: •FIRST INCIDENT: The MIL flashed and engine power...

was reduced while driving. The vehicle was taken to the dealership for evaluation and repair. A diagnostic code confirmed a cylinder misfire. •SECOND INCIDENT: Several days after being returned to the owner, the MIL flashed again and engine power was reduced, requiring careful maneuvering. The vehicle was returned to the dealership for further repair and remained in their custody for about a month. •THIRD AND MOST SEVERE INCIDENT: A few days after being returned, the MIL flashed again. The vehicle abruptly slowed, shook, and temporarily stalled in active traffic, requiring immediate intervention to avoid a collision. The engine restarted after pulling over safely. The vehicle has undergone compression testing, coil and spark plug replacement, battery replacement, and extended diagnostics with manufacturer technical support. Despite these efforts, the defect persists, demonstrating it is intermittent and unpredictable. The combination of sudden loss of engine power, stalling, and shaking in traffic creates a foreseeable risk of collision, particularly at intersections and in situations where predictable vehicle response is critical. Videos and diagnostic evidence document these recurring failures.

Suspension

Front Suspension (shock Absorber) uneven wear and bouncy, some vibration on the steering wheel at about 30k miles, on highway exit round about circle, the vehicle swerves left or right. very unsafe. long story short, drop it off at the dealership Lexus of Pembroke Pines FL, they said the issue was my tires and it needed to be replace, I rotated the tires rear tires went to the front and front to the back, no vibration, noise went away while driving, how ever about 10k miles later the uneven wear bouncing and noise...

came back while driving, Disappointed how the Lexus of Pembroke Pines handle my concern, i took my vehicle to Germain Lexus of Naples FL, I explained the problem with the suspension and they charged me to diagnosed the problem, charged me for an alignment, that adjustments were the same, before and after and told me, I needed new tires and it will cost me $1600 and my the issue will go away, Disappointed with that experience, i took the vehicle to the local shop and i was told that the Shock Absorber was the problem and it will only get worst unless i replace the shocks. Disappointed with how 2 dealerships give excuses not to replace or fix the problem while under warranty but expect the customer to spend money not to fix the problem is ridiculous, and in the end, the vehicle still unsafe while driving. front struts need a recall. Someone will loose control and crash due to the front shocks.
