Lexus IS 350 Problems by year

no power inside. It was at the dealer October 10-16. The problem was not fixed. October 21, 2026: The vehicle went back in for the same problem at a second Lexus dealer, and it is still there as of October 29. The problem continued after the battery was replaced. In total the vehicle has been out of service at least 15 days within its first six months. The dealer suggested driving the car more often, which works around the problem but doesn't fix it. A new vehicle should start after sitting a few days. Other owners of the 2026 IS 350 report the same no-start problem and being given the same advice. I have opened a case with Lexus (Case #261014000097) and sent written notice to the manufacturer.

operation unless the vehicle/system is restarted. The infotainment/display screen also intermittently shuts off, goes black, and/or repeatedly reboots while the vehicle is being operated. These failures can occur unexpectedly while driving. The display is also used to provide visual information and warnings associated with vehicle safety and driver-assistance systems, including Parking Collision Warning and Rear Cross Traffic Warning. When the screen unexpectedly shuts off, goes black, or reboots, these visual warnings can be interrupted or unavailable on the display during the malfunction. This creates a safety concern because visual information intended to alert the driver to surrounding vehicles or obstacles may not be available when expected. I am reporting the loss/interruption of the visual warnings displayed on the screen; I cannot independently determine whether the underlying sensors themselves continue operating during a screen failure. The sudden loss of the display and repeated rebooting while driving can also create a significant distraction. This is especially concerning at night, when the unexpected change from an illuminated display to a black screen and subsequent reboot can draw the driver's attention away from the road. The vehicle has been brought to an authorized Lexus dealership multiple times for audio and infotainment-related complaints. Multiple speakers have required replacement after becoming inoperative, blown, or distorted.

simply 'lubed' the rubber around the gas cap, reset the dashboard warning lights, and returned the vehicle to me without performing actual mechanical repairs to the braking system. The service manager explicitly instructed me that I must drive the vehicle back to the dealership every single week just to have the safety lights turned off manually. Driving a vehicle with an active, un-diagnosed braking and crash-system fault is a major safety liability and makes the vehicle dangerous to operate. The manufacturer and dealer have failed to resolve this safety defect under warranty."

separation in the exact same location, including vehicles that have not been modified or involved in collisions. My concern is that: The crack appears at a structural mounting point of the bumper. Continued stress or separation may compromise bumper retention. Progressive separation could create risk of partial bumper detachment at highway speeds. The issue occurs adjacent to the headlight assembly, raising potential concern for lighting alignment or mounting stability if the condition worsens. This does not appear to be isolated cosmetic damage but rather a recurring stress point at the bumper mounting seam. If the bumper retention system is insufficient or prone to stress cracking, this could pose a potential roadway hazard if separation increases while driving. Given that Lexus has issued a Technical Service Bulletin regarding bumper sag/retention on this model, I am requesting that NHTSA review whether the front bumper attachment design presents a broader safety concern.

nodes on the left side of the groin, abnormal weight gain, debilitating fatigue, insomnia, loss of breath, reduced eyesight, loss of strength, joints pain, reduced cognitive ability, malaise. Additionally, the contact experienced hair loss that stopped once the contact stopped driving the vehicle in the month of June. The contact sought medical assistance, and the lab work showed low level of iron. The vehicle was taken to the dealer, and the dealer was informed of the issue. The dealer performed a detailing of the vehicle to resolve the issue; however, the contact continued to experience the symptoms while driving the vehicle. The contact hired Nal East Environmental Services(2021 Bridgetown Pike, Feasterville-Trevose, PA 19053) to perform a test on the vehicle. The test was performed, and the contact was informed that extremely positive levels of Volatile Organic Compound(VOC) was found on the vehicle. The manufacturer was notified of the issue, and the Doctor's letter, stating that the VOC presence in the vehicle had made the contact sick, was sent to the manufacturer; however, no assistance was provided. The vehicle was not repaired. The failure mileage was 15.
