One problem related to power door locks not working has been reported for the 2005 Chevrolet Suburban. The most recently reported issues are listed below.
Attempted to lock the vehicle using the key fob - all four doors locked - the rear hatch did not - tried the key fob several more times with the same result - opened the driver's door and used the manual lock button - got the same result, the four doors locked but not the rear hatch - for my 2005 model, and for several model years other than my 2005, I read many complaints about the same problem on this website prior to sending this - and many complaints about the opposite problem, namely, the rear hatch door locks and cannot be opened - there is no key hole in the door, only the key fob operates locking and unlocking the door - obviously a design problem that you ought to issue a recall on - and, read many, many complaints about the instrument cluster over many model years - again, obviously a design problem - why don't you folks make gm fix these faults ? - they are not few in number - they are not isolated - they certainly are not owner generated - make gm fix them - isn't that your job? thanks for your help and good luck, waiting to see in alabama.
