Looking for feedback on my options here.... in the interest of brevity I'll provide a quick hit-list of facts and can flesh out as needed.
BACKGROUND:
Purchased 2010 Hyundai Genesis Jan '15
Couple instances of brake pedal going to floor briefly.
Last Wed, it goes to floor and nearly causes me to rear-end someone.
Quick search indicates
Recall on brake fluid. Consumers press on the actual issue (corrosion of brake control unit due to incompatible fluid), Hyundai is slow to react and
fined by the government. They eventually agree to "inspect the HECU" while replacing the fluid.
Common sense indicates once the brakes have begun failing, corrosion has occurred. Swapping fluid may halt further corrosion, but does not repair that which exists.
Many online forums have threads tracking instances... it's common. It's intermittent at first then increasing in severity until the unit fails completely.
Replacement cost of the unit, with labor, runs $2-3k
MY EXPERIENCE:
Car dropped at dealer Wed. They take a couple days to perform service. I repeatedly state I want the ECU replaced. They agree to (nonbinding, I'm aware) repeatedly.
Upon Pickup.... ECU not replaced. It passed some test (duh, it's an intermittent prob) so it can't be replaced without Hyundai signing off.
I file NHTSA report on complaint and share report # with tech guy who shares it with hyundai. No luck.
I let them keep car over holiday weekend to attempt to replicate the problem. No luck (again, intermittent problem).
Hyundai corporate calls me and tells me to pound sand, nothing they will do.
I'm obviously NOT comfortable signing anything that absolves them of any liability for repair or consequences of failure. I'm guessing signing off on the recall work being performed will do just that.
What options, if any, do I have here?
