Short Answer - NO.
Why No? (you ask)
"Caveat Emptor" means Buyer Beware. It basically means that buyer must do their own investigation/due dilligence when buying something used. It applies when you're buying real estate or a used vehicle. No guarantees are given on these items. However, you're not always out of luck when purchasing real estate or a used vehicle. For Caveat Emptor not to apply the item purchased must be fundamentally different from what was actully advertised and what you intended to purchase. Following this discovery you must bring it to the other party's attention as soon as possible after the sale, and stop using the item immediatly to mitigate the damage to the item.
Here are the things that would work against your claim.
1. You received the vehicle you intended to purchase. Fundamentally different would be if they sold you a Suzuki modified to look like a Toyota, after showing you a Toyota first.
2. You have driven the vehicle 1000kms, not sure how long you've had the vehicle.
3. You also knew these vehicles are prone to this very specific problem.
