We have a Hyundai i10, bought second hand in May, one previous owner, 19,000 miles. Car has been driving like new up till last week. We were given two identical keys, neither electric, and last week there was an occasion when the 'spare' key was used. We're not sure if this made a difference, but the engine would not start, and would instead make pft, pft, pft noise as if it was trying to get going.
We then waited till we had the 'regular' key back and tried with this. Same problem. Through trial and error we discovered that the car would start on a second or third attempt, especially if the key was turned slowly. Very occasionally it's started first time.
We took the car to the garage (Arnold Clark) today and have been told after diagnostics that there is nothing wrong with it, and that it started for them every time with both keys. (They then tried to sell us some other things we weren't interested in).
What should we do now? The car has always started and ran smoothly up till last week. Should we go to another garage? Should we keep driving and just resign ourselves to awkwardly having to start the car each time? I'm concerned in case the car is showing a sign of deterioration and may fail to start altogether at somepoint, or break down.
Edit: Thank you for your advice! We just went to collect the car from Arnold Clark and it wouldn't start at all! So they've had no choice but to 'take it back' as its still on their premises. Will see what the outcome is.
Second Edit: Thanks for warranty comments, unfortunately for us the car is 7 years old! Took it to AC as we'd purchased it from them so recently.
