No warning lights on the dash?

 

Nothing to indicate that there’s a problem. Not even an alarm. Surprisingly, I traded my 2018 Stelvio for the same problem and was told that it was the radiator. There’re no leaks on this new car or even evidence of one having occurred……….unless the dealer did an excellent cleaning job before I bought it. I’m lost for words but would like to get suggestions of possible problems before I take it back to them for a check…..so that they don’t bullshit me

 

Does it idle OK? With the transmission in neutral how fast does the engine RPM increase if you floor the throttle from idle? If that is OK but it doesn't accelerate when in gear, then maybe some brakes are rubbing.

Have you put any gas in it yet? Or is it still using the gas it came with?

Try filling it up with good quality premium.

Have them check to see if a new fuel filter helps. Check the plugs to see if they are past due for replacement.

 

I have filled it twice in 9 days with premium gas. I’d be getting a diagnostic test before taking it back to the dealer

 

Parking brakes are releasing properly?

 

Yes, the parking brakes are releasing properly but there seems to be a vibration/grating feeling on the gas pedal

 

How many miles on your 2022?

Are you stepping on the throttle pedal, or are you STOMPING on it to get moving real fast real quick?
How hot is it where you live right now, and do you have the a/c on when you are having this issue?

I'm guessing that its all Turbo lag related, and this owner probably has a heavy foot.

How long did you own your 2018 for before you traded it in for this 2022?
And you had the exact same lack of acceleration issue, which is why you decided to buy the 2022, which it also must have had during the test drive, since both had the same problem.

I think you need to buy a completely different vehicle, that doesn't have a small turbocharged 4 cylinder engine.

The car has 5622 miles. I am stepping slowly On the pedal but need to press a bit harder when it feels close to a stall. I owned the 2018 stelvio for 4 yrs prior to the trade in but only started to have the same problem about 3 months ago. When I bought the 2018 and up until recently, I didn’t have that issue.

 

A radiator won't cause acceleration lag.

 

Yeah, since its a first time poster, I wasn't going to touch that comment with a ten foot pole.

 

Try getting 93 octane at different gas station.

 

I’d try that after my diagnostic on Friday since I filled up already today

 

Could be the AUX Pump relay.

Thank you, I’d relay all suggestions during my diagnostic

 

After driving the car any of the rear wheels seem hot? Don't touch them.

 

Not really

 

So, it is not brake related.
