Back up camera problem
 

Like some 2020 ES owners, my battery died shortly after taking delivery of the car (2 weeks) and led to some malfunctioning with the remote start feature through both and app and the key fob after jumpstarting the car (temporary fix is by unplugging the battery or 15/30 mins). Along with the remote start malfunction, the yellow guide lines that moves when turning the steering wheel don't appear anymore when using the back up camera and a warning sign appeared on the top left corner of my screen. I tried clicking the button on the bottom right, but that only changes the blue lines. Does anyone else have this issue or know a fix to it? TIA

I have a 2020 as well and have not had any issues. Bring it to the dealer ASAP.

I brought it to the dealership to diagnose the problem and they said the remote start malfunction is common in the 2020s and lexus has not found a permanent solution for it yet.

If I may ask, how did you restore your grid lines? Earlier this week, I had the same issue which is why I came across your thread in the first place: first time since I bought the car I didnt drive it in 48 hours and the battery was dead on the third morning. After I jumped the car, everything was way out of wack and took almost an entire day to start functioning properly. Very disconcerting for a 2 month old car of any make, thats for sure.

Dealership basically told me a different version of the same thing: that if left in a weak signal area the car can drain itself fast via the remote comms link. 48 hours seems like a very small window but I havent had time this week to circle back with them. I have yet to be able to figure out how to restore my dynamic guidelines.

My opinion is that the dealer is feeding you a bunch of BS regarding the remote comms draining the battery. I keep my smart key within 6' of my Lexus and have had a 2013 and now a 2019.
Neither car has ever had a depleted battery for any reason and the car sits sometimes for a week when I'm using the Corvette...:overhere:

Went to go to work this morning and my 2020 ES350 UL wouldn't start. I've had the car a few months and it only has 2100 miles on it. The car is always garaged. Also this car wasn't sitting on a dealers lot for months before I bought it. I purchased the car before it was delivered to the dealership from the factory. AAA came over and jump started the dead battery and I drove directly to the Lexus Dealer. They tested the battery and claim its good. The only thing I can think of is I've been working from home since March and the car isn't being driven nearly as much. They claim they battery could have been slowly ran down and they claim the computers and wireless electronics on the newer cars drain the batteries more even with the car turned off. My co-worker had the EXACT same thing happen to his 2020 Toyota Camry 2 weeks ago and he only had a few hundred miles on his. I'm keeping a close eye on this. I think I'm going to buy one of those small battery packs for jump starting cars and leave it in my trunk!

Regarding the grid lines problem, I brought my car to the dealership's service center a week after it occurred and had a technician take a look a it. He told me it was some electrical problem that could've been caused from jump starting the car and took care of the problem for me.
As for the battery issue, the technicians could not find out why the battery died after such short time of not being driven. But they said if it happens again, I am guaranteed to have my battery replaced free of charged.
Ever since then, I haven't had any issues.

Agree with this...my car has only 2200 miles in 6 months and has sat in my garage for 14+ days at a time between trips. So far (fingers-crossed) no issues with my battery.

It's just not a normal occurrence to have a new battery discharge for no apparent reason. If a car sits dormant on a lot for a period this can happen. However, once started and run, the battery should remain in a charged state if, in fact, it is not defective. FYI - if a battery is discharged and recharged numerous times this will kill the battery in short time due to sulphurization of the cells.

added "sulphurization"

When I inquired at the Dealership about getting my battery replaced under warranty especially considering how new the car was he laughed and said the warranty doesn't work that way and they have to diagnose it being defective first!

That actually makes sense. They won't just throw parts at a car without diagnosing what is defective or failing.

I suspect the problem is not the battery. I think the question is what's draining the battery. If I'm correct, replacing the battery will not solve the problem. A new battery will experience the same drainage issue.

It seems like there are a few people having this problem with 2020 ESs. I don't recall this problem being common with 2019s. It looks like it could be a manufacturing defect. I agree that the dealers are giving you a line of nonsense about the remote being nearby. Is there a diagnostic they can run to test the amount of drainage occurring when the car is turned off? Is there a metric for how much drainage is normal and how much is excessive?

.I suggest you start a thread with a title appropriate to the battery drainage issue for 2020 ESs. It will be interesting to see how many 2020 ES owners have this problem.

I also agree with this, although our smart keys might be more like 8' away from the car. I "imagine" the dealer might have been referring to the remote app capability or the WiFi hotspot, which works via the cellular network and not just the smart key? I still think its a load of BS. Our ESh sat in the garage from December (while we used our SUV in the snowy weather) and January (while we were vacationing in the South) and then at least February as the pandemic started to take hold. We don't use a battery tender but our car is a hybrid which has a little different battery. Anyway, we haven't had any problems and this isn't an unusual idle period for our vehicles (perhaps explains why our 4 year old 2016 only has 16K miles on it...).

Just out of curiosity, do you have your WiFi hotspot enabled on your car? We do not. We decided it just wasn't necessary as we can use the hotspots on our phones already and they have unlimited data. I was just pondering if it could drain the battery faster if enabled. Again, just thinking out loud as to what might be different with your car that could justify faster battery drain. We also keep our cars in a secure/alarmed garage so we don't lock them at home. If the car is locked and "listening" for the arrival of the key it will surely use more battery power.

It may be worth pointing out, there were issues with a few of the last generation of ES vehicles and they had a battery drain problem related to the Network computer. Here is a link to that TSB: https://static.nhtsa.gov/odi/tsbs/20...86305-5448.pdf. Perhaps this is a similar issue? Here is a link to the thread discussing it in the 6th Gen subforum: https://www.clublexus.com/forums/es-...nd-2014-a.html. This may be a similar issue and may only impact a few of the vehicles as was the case with the last generation.

That's a bad idea because letting a battery drain frequently until it needs a jump will shorten the battery life dramatically. 2 years instead of 4-5. A better solution is to install a maintenance charger made specifically for cars parked for long periods. You leave it plugged into the wall, it won't overcharge or damage battery. Amazon about $20 called battery tenders.

I started a thread for 2019-2020 Es350 for battery drain issues. Join us https://www.clublexus.com/forums/es-...ain-issue.html
