What's the most expensive thing that goes wrong?

Paste your VIN into the decoder at the top of this page. We pull live from NHTSA, so you'll see exactly which campaigns apply to your vehicle and whether the dealer has logged the fix. Recall repairs are always free regardless of mileage or warranty status.

Is an extended warranty worth it on a 2020 Cadillac CT6?

Math is straightforward: a quality service contract runs $1,800–3,500 over 3 years. With 11 complaints on file and the costliest repair averaging $2,500, one major failure more than pays for it. The catch is reading the contract — many providers exclude wear items and require pre-authorization, so cheaper plans aren't always better value.
