It has long been rumored to be cautious when taking you vehicle for repairs to a new car dealership when it is out of warranty. I have personally experienced these kinds of incidents here in the Columbia area before. The latest being yesterday 9/26/19 at Love Buick/GMC. My wife owns a 2013 Back Enclave which she purchased used from the dealership about 4 years ago. Last week a mechanical problem developed with the lift gate. The hatch would electrically rise to the open position but, once fully extended you could hear and see the lifting rod jump and then the hatch would automatically close. I have some auto mechanical abilities through experience working on muscle cars in the 60s to the present time. However I did not want to fool with this issue due to an air bag in the general facility and felt confident about this dealership. Car was looked at and diagnosed to have a bad actuator. Total cost for repair was $880.90, $585 for the part alone. I inquired if there was away to by pass the actuator and just set up to manually open and close the hatcht? I was advised that there was no replacement part available to make that change. I decided that I did not want to have the repair done and paid the $89.95 diagnostic fee. Later I went online and found that I could purchase ACDelco actuator part#23245268 for $190.16 from Amazon, which I did. Having no experience with attempting this repair I managed to remove the actuator in about 45 mins. I visually examined the unit but, was unable to see any damage to it. Dump founded at this I stood there thinking about this problem when I noticed the two lift struts on either side of the hatch. Left one was good, right one had 0 resistance. Purchased 2 new struts from Advanced Auto for $69.80 with Limited Lifetime warranty. Installed the new struts, replaced the original actuator and all is good. This review is not intended to question their prices for making repairs. It is about leaving it up to you the reader to form an opinion about what occurred. One thing I would suggest. If you are having unknown issues with you car which was discovered by a repair facility, if possible, always ask for the replaced part if you are in doubt.
