I also have the 2020 Discovery sport. My car completely cut off on I-10 with me doing about 65 miles an hour. all this during rush hour in Houston Texas. It was extremely scary with people hitting their brakes and blowing horns as i try not to get T-boned by an 18 wheeler. I tried to call the dealership and was on hold for 15 minutes twice. The third time i called , they took my number and said they would call me back. They never called me. I drove to a dealership the next day and they told me that it was a engineering problem. Im so disappointed in this purchase. I don't want the car anymore. I called the dealership that I bought it from and they said they would call me back today but they didn't.

Can you tell me what dealership? I bought my 2020 at the Houston North Land Rover dealership.

Have been driving various Turbo Charge cars since the early 80's and in later years I have found that ethanol fuel also effects Turbo Charged engines. (specifically in warm weather) . I always fuel up with ethanol free fuel in Canada, traveling in the US it is harder to find unless you live in the area.

I can only think of two places where I live that sell ethanol-free gasoline. It’s definitely hard to find. Do you have any suggestions about additives that might help mitigate the effects of ethanol fuel on turbos?

I think all additives have alcohol has the main ingredient and others may have great claims but ???
I am lucky I have 3 stations selling non ethanol fuel within 4 blocks of my home. 2 Chevron with 94 octane and a Shell with 91 octane.

I have a new 2020 Discovery Sport with 1700 miles and two months old. It has stalled 20 times and has been towed twice to the dealer, Ken Garff Down Town Salt Lake City.
It doesnt matter wehther the eco stop start button is on or off, if it is over 90 degrees in ambient temp and I am heavy stop start traffic it will just fail. When it happens which is often a t set of traffic lights, it goes into a limp mode and I can only move forward through the jucntion at 1 mph which is extremely dangerous. Then the engine may or may not start again.
The Discovery has now been towed in twice to Ken Garff and they have found three possible faults, an alternator that may be over charging, A transmission module that is ablaming the transmisssion and a transmission that is blaming the module!!!!!!!
So after owning it for two months and 1700 miles I am now looking at lemon law possibilities as this car leaves me thinking that it is a lemon. I managed to video the last three ocassions so that the dealer can see what happens.
I forgot to mention that before any of the current issues, I had two covers that fell off the car, an underside panel that covers the engine bay and the front towing eye cover. Not a great start for me with the Land Rover brand.

I just stumbled upon this post (I know it's been over a year) today. I have had similar issues and Ken Garff Downtown is my dealership. It's been over 90 in SLC this week and I had the same stalling issue. I'm getting my car back today. I read through the thread and not sure if a better grade of gas is the answer. I would love to know the resolution of your issue from a year ago. I have a 2020 Disco Sport w/ 4900 miles on it. Purchased a month ago.

Read your manual , premium is needed and it says the same on your gas cap. I know your state has low octane standards but spend the extra. If you can get pure gas use it ,,,,non ethanol.

I have driven in temperatures in excess of 43 c in the mountains with no problem. We have just had a major heat wave with temperatures nearing 50c and nobody has had problems with any manufacturers car.

Thank you for your response. Gives me some comfort. I'm wondering how the original poster's issue was resolved. For me, having the car only one month is concerning.

It may take a couple of fuel ups to clear all the low octane fuel from the tank. Also use a major "Top Tier" fuel.

I have been advised that there is a national problem with the 2020 discovery sport. When operating at high temps, over 90 degrees and in high altitudes there is a problem idling under load. They still have it in the workshop for the last 5 weeks with no sign of a cure yet. This has happened at several locations, it’s not just mine that is affected

I own a 2019 Discovery Sport HSE Lux and have had it towed to dealership twice in last 1000 miles. First time it just locked up and looked like computer went out, no steering and all safety features not working or disabled. Was without vehicle over a week, they said it was a software issue, no loaner. It acts like it slips into low when taking off at a stop light, surround monitors quit working within first week, cooling fan was running super loud and hot after 2 hour trip. Lane keep seems to stick and fights you when you try to change lanes. Surging acceleration on occasion.Air condition acts up. It’s at a different dealership at this moment, I don’t have a loaner and don’t have a clue yet. New with 14000 mi

what this guy said….these vehicles (and ANY forced induction gas engine is supposed to use high octane fuel. The owners manual says it . The sticker on the inside of the gas door says it! In UT that is 91. 85 absolutely should not be used and could well cause the problems being complained about here.
