I have had similar Problems. In an effort to avoid the Hassle I went through.
Speak to several Reputable Auto Attorneys. Find one who will take you case and not pass it off to some damn clerk !!!!!!! Very Important!!!
Smaller Firms with Younger Attorneys Looking to make a name are better. The Old guys, know the judge and would rather be golfing(as would I)
By a MP3 Phone recorder. You can buy a very nice one for 150-200. Mine can even be hooked into my cell phone. Nicer ones are available since I have purchased. try a private detective/cop store online.
People have a gut reaction to defend themselves. This is why Court testimony is always recorded. Get them on the phone and see how they behave. Never Tell them they are being recorded. Listen as they change thier story time and time again. All the while you have everything recorded and documented. Judges Love this stuff. Makes it very easy. I Hired a court circuit Judge and he Was Great. Next, while you are documenting everything, get statements from the dealership that found the problem, and take pictures. Always better if a Professional does it. More Plausible. but you should get the initial statements in writing from the dealership, before the big hullabaloo. This will save you "Associate" fees and get the dealership who discovered it on your side in writing before the two in house "REsolution Dispute Specialists, (who toyota will call) Get together and decide to screw you. Remember, They work for a Dealership, not Toyota. Thier is nothing Dealers fear more than a strong documented Lawsuit. Just the Legal Fees outweigh any profit they could have made. Which is why when you call, and the right people find out oabout the call, everyone in that dealer will know who you are inside of ten Minutes, and they will all be told to keep thier mouths shut or be fired. Salesmen sell 10-20 % of the day, the rest is BSing and trying to sell. Grapevipes like ...
Make sure anything you agree to is in writing!!! And that it is binding on them and does not release them from Liability.
Consider that if the Vehicle had been in an Accident, and they the dealership did not Disclose it and they knew about it they have violated so many damn Laws it is not even Funny. Legally they will have to buy the Truck Back under the Federal Lemon Law. Just get your Facts Straight and Documented before you call them and expose their secret. Initally the dealer told me the car was fine, It had made it past thier Rigorous certification process. The "Pre-Owned" Car manger and the New Car manger told me how it was groundbreaking and award winning, how only Master Technicians Work thier, They Don't make mistakes like that. They were however very curious to know exactly what did happened. But thier Lawyers told them not to say anything and to Direct me to them. So I found the Previous owners, called them and asked. Fender Bender, Knew they were going to buy new again shortly so they paid to have the dealerships autobody shop fix it. I had a friend in the Parts Department, so he called a buddy in the shop and they found the previous Owners Work Order in the COmputer. This was Highly Illegal, as their are strict confidentiality laws to protect the PO, but I said I wouldn't sue IF... But I had to have a Lawyer and a day in court, plus all the paper work. The Pre- Owned Manager became Extemely apologetic. But not until I had papers in hand. Maybe after you get statements from the current Dealer, call the Body shop Associated with the Previous dealer and give them your VIN, say "I know you guys did some work, on this and I was just wondering if you could fax me a copy of the work order for the records." I did that on a LS after I bought it and found out that the PO had the doors repainted because they got scraped. I knew of the PO and had contacted him before the purchase, and he didn't tell me that. After I owned it I asked, found out, called him and asked and he said that couldn't be true. When I reminded him Exactly what had been done on what day and told him I had the work order, he apologized and said it "must of slipped his mind". Some jackass scrapes my brand new LS430 and I don't think I would ever forget it, or have the door skins replaced and repainted. would you. People want to protect themselves. I would too, which is why if you ask me what my grades were in my senior year of High School, I will tell you everything but what you need to hear, I was by the way a GeniousS! LOL
What ever you do, don't talk to the selling dealership until you have all your documents, and can document what they say.
I pray this works out for you. Other Gentlemen on here have not had great Luck dealing with dealers. I think you are taking the correct steps.
