2019 Mirage 1.2L with CVT, noticable pinging and detonation with 5,800 miles on odometer. No change in fuel brands or octanes, tried 87 and 89 fuel. Any ideas? No engine codes but getting worse as miles pile on car

My starter went sour very early on in my Mirage. Best of luck! Damp weather the other night starting up and I heard some weird noises. Then were gone. My Mirage has 131,000 km's on the od and is a 5 speed manual. Idles very quiet.Quote:

The car is fully warm after 45 mile highway run at 55-65 mph. Coast down an exit to a flat road. When red lamp turns to green, gentle acceleration the engine goes "ping ping,snap, ping" at takeoff. Only to to stop it is let off gas pedal or go WOT at 5,000 rpm where it gets so fast you only hear the engine roar.Quote:

I agree with Dirk. If your car is less than one year old & under 12,000 miles, it shouldn't cost you anything to have this checked out at the dealership.Quote:

Well...if there's no coolant around the temperature sending unit, the hot light won't turn on even though the engine is overheating.
It's just a possibility but it only takes 30 seconds to check it. But I agree with you guys that it's under warranty so get it in ASAP if it really is pre-ignition noise you are hearing. That's not good for any engine!
