I have been a long‑time customer of Mike Haggerty Buick GMC, and this is the first time I have ever felt the need to post a complaint. Unfortunately, after multiple incidents and inconsistent information from the service department, I no longer trust this dealership with my vehicle.
On 03/03/2026, I came in for an oil change and a tire sensor error. When I got back into my car, the tire sensor light was still on -- I hadn't even left the lot. I walked back inside and informed the service advisor, Pedro Zavala, who seemed rushed and frustrated. He had previously told me the issue was fixed when I asked before paying.
He then took my keys, drove my vehicle around the dealership several times, and brought it back into the bay. After about 10 minutes he returned and told me the TPA was bad and that he had temporarily gotten the sensor to work by spraying "something" to hold it in place. I had already waited over two hours, so I scheduled a follow‑up appointment.
At my 03/18/2026 appointment, the paperwork stated that Fix‑A‑Flat was found on the sensor and that the TPA was replaced for $278.36 -- consistent with what Pedro told me.
On 06/25/2026, the tire sensor issue happened again. Despite having a 7:00 AM appointment, I waited two hours before being told that Fix‑A‑Flat was supposedly used again -- which is completely untrue. I have never used Fix‑A‑Flat. I was then told I needed another TPA replacement, this time quoted at $390.
When I asked why the same repair suddenly cost more, the Service Director, John Coan, responded with:
"Why are groceries higher? Why is gas higher? Parts cost more and labor costs more."
This was dismissive, unprofessional, and did not address why I was being charged again for the same unresolved issue.
Both John and Pedro later claimed they would "never spray anything themselves" and that no such action was documented -- even though Pedro clearly told me on 03/03/2026 that he used a spray to temporarily fix the sensor. The conflicting statements and lack of documentation are extremely concerning, especially since I only service my vehicle here.
A reduced price of $260 was eventually offered, but no real explanation was provided for the repeated failure, the inconsistent Fix‑A‑Flat notes, or the pricing differences.
I have recommended family members to this dealership over the years, and they have experienced similar issues. This is my second incident, and after the repeated problems, contradictory information, and the way I was spoken to, I feel insulted and will no longer be returning.
Bottom line customers deserve honesty, consistency, and professionalism -- none of which I received here. read more
