Complaints by Component

ENGINE,FUEL/PROPULSION SYSTEM

1 complaint

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

1 complaint

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.
