IrelandI bought a car with undisclosed mechanical problems.
If you bought a car in Ireland with undisclosed mechanical problems, the seller may have breached the Sale of Goods and Supply of Services Act 1980, which requires goods to be of merchantable quality and fit for purpose.
What the Law Says
The Sale of Goods and Supply of Services Act 1980 sets out basic legal protections when you buy a car from a business seller in Ireland.
Under section 14 of the Act, when a seller sells goods (including cars) in the course of business, those goods must be of 'merchantable quality' — meaning they must be in a reasonable condition, safe, and free from hidden defects that would make them unsuitable for normal use.
The law also requires that goods must be 'fit for any particular purpose' made known to the seller at the time of sale — for example, if you told the seller you needed a reliable car for daily commuting, it must meet that need.
These rights apply automatically — you don’t need to sign anything extra or ask for them. They do not apply if you bought the car privately (i.e., from an individual, not a business), unless the seller made specific promises about its condition.
Statutory TextWhere the seller sells goods in the course of a business and the buyer, expressly or by implication, makes known… any particular purpose for which the goods are being bought, there is an implied condition that the goods supplied under the contract are reasonably fit for that purpose.

What to Do
Contact the seller in writing (email or letter) explaining the problem and asking for a repair, replacement, or refund.
Keep all evidence: purchase receipt, service records, photos/videos of the fault, and copies of all communication.
If the seller refuses, you can make a claim in the Small Claims Court (for claims up to €2,000) or the Circuit Court (up to €15,000).
Act within 6 years of discovering the fault — this is the general time limit for breach of contract claims in Ireland.
