Hey Guys,

We recently spent 2 days in Las Vegas during the hot summer and got both warning about LKAS & Forward Collision Warning Problems. Did anyone know how to clear or reset this? or is this something to easily fix? I own the car about 5 years and never have any problem in California hot weather, just recently drove to Las Vegas and gave me both warnings. I know temperature in LV is super hot but is that mean the sensors is bad? I got the warning again other day in California (temp around 108 f) and gave me those warning again, I turn off the car and start again and the message disappear.

It should clear by itself. Noticed similar warnings when I parked my 15TLX in hot sun couple years back, it went away by itself.

It sounds like the camera is overheating and shutting down. You might need to park in the shade and crack the sunroof a bit if you can. The good thing about "dry heat" is it can be 5-15 degrees cooler in the shade compared to high humidity places.

To be honest, I own the car for over 5 years and always leave it directly to the sun and hot summer here in CA but never got those warning before. Just drove to Vegas for 2 days and already have a problem. :)

Phoenix/Vegas summer heat is on another level entirely! It is the direct sun, concrete, asphalt, reflective glass on buildings, lack of green space, and humidity from water features/irrigation that pushes the heat to feel more intense than the thermometer indicates. Asphalt and car interiors would get 140-170 degrees in summer when temps got +110 degrees when I lived in Phoenix.

My ‘18 did the same thing at 117 degrees. It went away at 113 degrees about 5 minutes later, without restarting the car.
