Purchased a brand new XT6; the radiator began leaking at only 40k miles and the dealer quoted me $3500 and said it needed to be replaced as it was entirely plastic. Cadillac refused any goodwill assistance as the vehicle was 8 months past warranty. We had referred several family members and friends to purchase Cadillac vehicles but will certainly never make that mistake again. Also of note: the customer service representatives at Cadillac were some of the most condescending folks I have ever had the displeasure of speaking with.

Failure to Disclose Potential Pre-Existing Defect
I am extremely disappointed with my experience at Cadillac of South San Francisco (775 Serramonte Blvd, Colma, CA 94014).
On October 15, 2025, I purchased a 2023 Ford Mustang Mach-E from this dealership. The vehicle was sold as-is, and no mechanical issues, prior damage, or concerns were disclosed at the time of sale. Given that it was a 2023 model vehicle being sold at market value, I had no reason to believe there were any major underlying problems.
However, on January 31, 2026 — just over three months after purchase — the vehicle suffered a catastrophic mechanical failure. I was informed that the estimated repair cost is approximately $9,000. For a vehicle of this age and value, a major failure of this magnitude so soon after purchase is extremely concerning.
After the breakdown, I contacted the dealership and spoke with multiple managers in an effort to resolve the situation in good faith. Rather than showing concern or offering any form of assistance, I was told they would not help because the vehicle was sold as-is. There was no willingness to review the situation, no offer to inspect the vehicle, and no attempt to work toward a reasonable resolution.
While I understand what “as-is” means, I believe customers should reasonably expect that a dealership has properly inspected a vehicle and that it is safe and mechanically sound at the time of sale — especially when no issues are disclosed and the vehicle fails shortly afterward.
Due to the dealership’s refusal to assist, I have had to escalate the matter formally.
This experience has been extremely frustrating and financially stressful. I strongly encourage potential buyers to conduct very thorough due diligence and consider independent inspections

Extremely disappointed with Empire…
Extremely disappointed with Empire Cadillac's service. My Cadillac was delivered with a non-functional OnStar module, and despite multiple promises and months of waiting, they repeatedly delayed and mismanaged my repair order. They provided conflicting information, failed to communicate clearly, and returned my module without notice, unfairly using a canceled oil-change appointment as an excuse. This feels like deliberate negligence intended to push my issue beyond warranty coverage. Very unprofessional and frustrating experience—I strongly advise caution when dealing with their service and sales department.

Regretful First Time GM Owner
2024 Cadillac Lyriq with 1,500 miles:
1) On delivery day, interior panel on driver’s side separated from body.
2) Immediately began experiencing problems with CarPlay. The car has been reprogrammed, reset and updated multiple times since delivery. None of these fixed the multiple CarPlay issues.
3) Lower passenger’s seat cushion came apart.
4) Brakes failed. The car spent one month at the dealership.
5) Faux leather on steering wheel began separating from the area around the Super Cruise indicator.
Cadillac EV Customer Care have been of no assistance. They promise to call you back, but do not. After sending an email to CEO Mary Barra, I was assigned an Executive Customer Service Specialist and was given a case number. This specialist did not return calls as promised.
Next step will be to pursue Lemon Laws in our state. My goal is to have GM repurchase this disaster of a car.

servizio assistenza inesistente
Ho acquistato una Cadillac XT4 nel 2021, ho perduto una chiave, nel contempo hanno chiuso la concessionaria di Roma ed ora per avere un duplicato della chiave debbo pagare 560 euro e portare la mia vettura a 600 km di distanza dove è il concessionario più vicino, quindi andata e ritorno 1200 KM, benzina, autostrada, pernottamento in albergo, pasti, etc il tutto per la modica cifra di oltre 1200 euro e 2 giorni di impegno.

I was denied a transmission repair…
I was denied a transmission repair under my warranty and forced to pay for a $1500 transmission flush instead. Beware of Cadillac, they don't honor their warranties! Cadillac knows their transmission is defective! I have read other customer complaints online. What a ripoff! I will be filing a BBB complaint and lawsuit!
