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

You get weird noises from time to time with these weird little engines. If your not throwing any codes I wouldn't sweat it, otherwise just get it checked out under warranty.
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.

What did the mechanic say? You should get a free diagnostic at a dealership.

This may sound crazy...but check your radiator. Is it full of coolant? An overheating engine will knock and ping like BB's in a coffee can.
So I can hear you guys out there saying... "But he didn't say his engine temperature warning light was on."
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!
