While the car was idled at a stop light, the warning "reduce engine powere appeared". I took the car to the vehicle and learned this was linked to code P125d71 for fuel pump valve control- a known recall

In heavy rain situations I get an error message stating all front active safety systems (forward collision warning, etc.) do not work. The error states to clean or clear the front sensors of the vehicle. There is nothing blocking the sensors but in heavy weather these situations become much more important. Lexus states this is normal when heavy water situations come into play. I understand for going through flood waters but I don't believe it should be in heavy rain. I feel this is a major safety hazard that should come with warnings.

Car was running normally and going at 50mph then all of a sudden car abruptly lost power and went to 10mph and dashboard lit up. Very scary as we also had our kids in the car--I can only imagine how dangerous this would have been if we had been on the highway going 70mph. Dealer diagnosed with low pressure fuel pump being bad. Lexus paid for the repair due to some lawsuit settlement but these cars should be recalled due to sudden loss in power!!

During heavy wind driven rain the front sensors start to show errors on the screen. These errors cause the the advance safety systems and parking sensors to deactivate. The warnings state to clean the sensors. Sometimes stopping the vehicle and turning off and on the ignition seems to resent but it does happen again. Usually this takes about 30 minutes of heavy rain to cause the. All other functions of the vehicle work but most safety systems appear to deactivate because of the sensors. This should not happen during a time when the systems are most needed.

Trunk is defective. Trunk will not open unless it is manually opened, which is hard because it is powered. If there is an accident and a person needs to escape, they would be stuck inside due to these defective trunks. Many others are experiencing this issue online.
