NHTSA complaint #10731939, 2015 · fire

“Attached is a report from the Florida Attorney General's project office. Vehicle front headlight bulbs burn out prematurely and frequently and without warning causing reduced visibility at night on dark roads. This is a common and on-going problem for Toyota and other manufacturers and me. Toyota recognized this and issued its own recall ending in 2019, but my car was missed. The 'fix' for me is advice that I should drive my car with high beams on, but in bad weather or on-coming traffic this fix is also a safety hazard. My fear is that one night both bulbs will go out and I will be unabl…”
NHTSA complaint #11629190, 2024

“The low-beam headlamps on thousands of 2011 Toyota Priuses were burning out very prematurely (a matter of weeks, not months). Toyota Corporate said they created a customer support program to replace the headlight wiring harness free of charge, but this program ended in 2019. I believe that Toyota should be compelled to issue a recall to replace the wiring harnesses on all 2011 Toyota Priuses, because working headlights are a critical component of a safely traveling vehicle. The cost of replacing the wiring harness is more than $700, a real dent in a working family's budget. For now, we are rep…”
