Are all the doors locking ? If a door lock is not working, you many not get the confirmation chirp.

Lock the car, put the key away from the car and check every door.

 

All doors and locks working properly. Everything works fine. No key involved here, this keyless push button start system. Beep worked fine until yesterday????

Been throught the set-up screens, door-beep setting is correct.

 

Just a guess, does the warning buzzer(chirp) operate when opening/closing the power liftgate? If it doesn't, the buzzer is likely bad or has a bad connection. If it's still under warranty, I'd get the dealer involved.

The rear hatch beeps, works perfectly....issue only the when locking and unlocking the doors. Both with the fob or touching the door handle. Lights flash just no beep. All settings are correct. I intend to visit the dealer in the morning. Judging from some web searches today, this not an uncommon issue. All with same mysterious cause, many had different recommendations(various series of fob button combinations) non we're helpful. Thanks for everyones thoughts....appreciated.

 

Wires insulation and some tires. They use something that attracts rodents, so if you stow tires uncovered outside, rodents will chew on them.

 

Rodent damage to wiring is caused by the use of soy-based automotive wire insulation.
