I have received a letter sharing I have been approved for a settlement check. However: I have to sign the form that was sent to me before the check will be sent out. The contents of their approval letter includes a paragraph which states that I am giving up future rights to other class action suits. I have not returned the signed letter because of that paragraph. I have received 3 follow up letters from them stating that I have not signed my agreement yet and that letter is needed before the check can be sent. The hesitation in throttle response from a stop has become worse since the recall was completed on the exhaust system.
