My question involves a consumer law issue in the State of: Oregon
I recently bought a used vehicle from a dealership, came with 90 day 50/50 warranty. I took the car in the other day to have the breaks checked at a firestone, they called me over during this and showed me some interesting stuff, the rear knuckle on the driver side was the wrong size along with the rotor, due to this no mechanic will replace the breaks since they don't even properly touch the rotor and the current brake pad hangs over the rotor. The mechanic also told me that that parts back there had been replaced with junk yard parts (you can see the labels from the junkyard) and the rear side if you try to stick a magnet to it (which the mechanic did when they saw the parts) it wont stick but the rest of the car the magnet stuck. Its like the whole rear left side was replaced, now I know it doesn't show any accident in the carfax, but the car has clearly been in an accident.
Do I have an rights in this? I know in Oregon a dealer must disclose an accident, but does that apply if it hasn't been reported? Also as it has been 2 months since I bought the car can they use that as an excuse, that I could have done it? If they choose not to help me, would this fall under the 50/50 warranty? And if all fails, do I have a leg to stand on in small claims court?
Overall I wasn't happy with my service with them, they lied to me on a KBB price, they refused to do the recall on my car, even though its an infiniti and this was a nissan dealership, they refused to fix something as simple as a bad light bulb when I bought the car. So I obviously am not happy with them. Any suggestions? Thanks
