In NJ you do not need a lawyer to pursue a Lemon Law complaint. The law is clear as to what constitutes a Lemon, the obligations of the company and the obligations of the consumer. For a $50.00 the NJ Department of Consumer Protection will file your Lemon Law complaint for you and work with you thru the process. There are very strict and clear cut time lines.
It is very important to bring your vehicle into the dealership for warranty service the very first time you have a warranty issue because in NJ that sets the standard for all future actions. For example, if you have a warranty issue at 425 miles and bring it in to be serviced, then down the road it turns out that you do actually have a lemon, even if the actual lemon issue is different than the original warranty issue, the mileage is set at the original 425 miles.
I would also ask the dealer service manager to tell you in writing if you can use the vehicle or not. In NJ once the vehicle is out of service for 20 days total, does not have to be consecutive, it could be declared a Lemon. If the dealership tells you NOT to operate the vehicle that would be considered out of service. Even if its out of service for 15 days for this and then later on during the first 2 years it is out of service for another 5 days total, it could trigger the provisions of the Lemon Law in NJ.
In NJ there are 2 options that come into play regarding vehicles that are "Lemons". One option is an exact replacement of your vehicle, no price negotiation, exact replacement and if you want any extras or upgrades you pay full MSRP for the upgrades.
Option # 2 is the manufacturer does a vehicle repurchase. They buy your "lemon" for what what you actually paid for it, including anything you added including extended warranties, service contracts, accessories such as a winch, trailer hitch, floor mats, 2 way radios, lighting etc. as long as you have the receipt for the added equipment, including any sales tax you paid on the vehicle or the added equipment. There is a formula they use regarding mileage that comes to about $0.28 per mile that get deducted, based upon the mileage when you first started having problems. So, it is very important to report the first issue you have. Proper reporting could save you a substantial amount of money. 10,000 miles equals $2800.00 nothing to ignore. With this option manufacture sends you a check, you can take it and do anything you want with it !
