I installed LED bulbs in the low beams and running lights in my 2011 a couple of days ago. I did notice some quirks when I initially tried to turn the light switch to initiate them as I was installing. Lights on the dash went off and the push button start would not initiate. It’s as if the car froze up. I had to unplug the new bulbs to start and refresh the system but the car started right up and didn’t appear to have any issues. Therefore I next plugged them back in and started the car before turning the light switch on and they worked. After that point it was fine to turn them on with the car off so I thought perhaps it was just an initial acknowledgment or CAN communication of some sort but I didn’t think much about it actually.
Later that evening the dash ignited while driving with AHC errors, all sorts of error messages and yet the car was still running. The dash eventually turned off as I recall but kept running. A few minutes later though it just stopped in the middle of the road. It would not even attempt to restart. The side marker lights also remained on, which are not LED, with the car not running but the switch was still in auto. I think perhaps the truck didn’t recognize the turn off as it wasn’t turned off but rather just ran out of power and shut down.
I removed all the new LED headlights, reinstalled the old and attempted to restart the truck. The dash lit up as it thought about starting but no juice and it didn’t turn over or even attempt to. With jumper cables the truck did start but immediately died once the cables were removed.
Took the Lexus battery out and went to the dealer who tested the battery which had only 300 amps so they replaced for free. Obviously the battery was drained but was this just a coincidence with the LED headlights or could they possibly have fried the alternator and charging system with an electrical system issue?
With a new battery installed the car started immediately and ran fine but the battery light was on and the amps meter showed the alternator not charging as the amps were level at around 12 as opposed to higher. Drove the car immediately to the shop who is replacing the alternator as the car was not charging while running.
So back to my question- is it possible these headlights caused this issue or just a really strange coincidence? Low beams were Sealight H11, X1 model, and I know others have used Sealight with success. They look the same as the Hikari actually and fit in the housing with the original cover same as Hikari. They are the No fan design.
I look forward to the input and feedback.
