Sudden Loss of Power or Limp Mode

[EOD Guy]

This is the one I bought on the recommendation of the tester guy on UTube, He has always been spot on in his live tests, it's a bit pricy but since he came out with his side by side test with all the jump box tests people are buying them all up.

This was smaller than I expected, which is a good thing. It's about the size of a 70's lunch box, perfect. Has a USB and a USB-C port.

I just had a loss of power. I was trying to take a left hand turn into traffic. I had been waiting for a while so it went into hybrid mode. As I pulled out, it was going about 10-15 mph (traffic was going avg of about 40 mph). I stepped on accelerator harder and it kept going slow, then suddenly, the gas engine kicked in and it took off. It was like there was a glitch and the gas engine didn’t kick in when it was supposed to. No error codes came up and it’s running fine now. Anyone else experience something like this? I have an appointment to take it to the dealership next week. They said, if it’s not covered under warranty, they’re going to charge me $210 for diagnostics. I said, it should be covered, it’s a brand new car!

I’d find another dealer..

Pretty sure what they mean is: If we don't find an issue, we are going to charge you. If we find an issue, we charge it to warranty. By no means am I taking up with Stealerships, but can't say I don't blame them........ Can't keep in business if a you put a guy on a customer's vehicle for a couple hours with no recoup of the manhours. They could probably eat one or two occasions but not repeatable. I have on many occasions, had a dealer diagnose an issue I couldn't figure out, pay their fee and fix it myself.

I should stop reading this thread. Getting a headache and worrying too much. Not listing the 4runner for sale just yet....
Actually staying optimistic. Love the LC. Just want to make sure it gets me from point A to B reliably.

I also live in Virginia and can tell you 3,700 miles in, not a single hiccup. Sadly these cases are outliers and happen with new vehicles. It's like a 98% chance you'll get a good one, 2% chance you find yourself in these situations, maybe less.

I had this same issue driving on I70 to the mountains in Colorado... luckily there was construction so we were going slow and I got off at the next exit. Restarted the car and it drove fine, but took it to the dealership and they could see that it happened but didn't have a reason for it or had any suggestions / adjustments. Would love to get a better understand of what is causing this

It’s a double edge sword. When I read some of these threads, I stress out and I feel like I hear all of the things and see all of the things.- smell all the things.. And a lot of times I wonder if it’s in my head after having read stuff. But then the threads come in very handy also, otherwise I would’ve never looked for the dents at the top of my roof with my FE rack and had them fixed before I even left the dealership with my new LC. Some of it is very stressful and some of it is incredibly useful - thankful for the forum, but I totally understand your stress when reading certain threads.

What did they see exactly ? “Loss of power” code ? Somewhere someone stated these are brand new and the technicians at the dealerships Don’t know anything on them yet. I would say that’s accurate. I had mine in trying to get it checked out a couple of different times and the technicians literally say they don’t know anything about the land cruisers yet, which is sad and maddening all at the same time. Which is why this forum is so great. We are all learning from each other more than we could ever learn at the dealerships.

I hear ya! I've thought about posting a thread titled "Doomscrolling". I had one minor issue with my LC/LC (warning light) on the first day of ownership but it's been flawless ever since. I've concluded that following all of the "problem threads" really hampers my enjoyment of a spectacular vehicle that I love LOTS more than my previous 3 4Runners and FJ. From now on, I hope to only query threads that address my specific questions.

Same issue as the OP:

1. Drive-Start Control Malfunction Visit Your Dealer
2. Hybrid System Malfunction Visit Your Dealer
3. System Malfunction Visit Your Dealer

 

[RRanger1996]

The dealer gave me very little information outside of your car is fine, this has happened before, and the most likely culprit is that the computer read something and went into safe mode to protect itself.

Mine happened on Friday and took it to the dealer on Wednesday (first appointment). Order of events

• Friday Night: Car freaks out on the highway, pull off at the next exit
• 10 minutes late: Turn car off, restart after a minute all errors but "Hybrid system malfunction" are gone
• 20 minutes later: Drive home without issue (50 minutes)
• Saturday morning: Call dealer and they say if no lights are on you can drive... drive to the gym with Hybrid system malfcuntinon error
• 90 minutes late: No errors, no issue
• Wednesday: Dealer gives me me the answer above...

So far so good... my guess is this will be software update in 3 months

I keep a 12mm socket wrench in the rear storage tray.......... Disconnect the neg terminal on the battery, wait for 5-10 min reconnect, computers will reset and might be ok......... and get me home

 

[b407driver]

Starting to wonder if some of these non-eventful 'multiple message' events are a result of brief decreases in voltage of the 12v battery. I really want to know more about the electrical system and why Toyota would allow the 12v battery to vary so much in voltage when it effectively has a 'built-in' charger (288v hybrid system).

I had the same exact issue happen with mine. Had it for about 3 week, 900 miles exactly, backed out of a parking space and went totally limp after 30ft or so. Same 3 error messages.
I was able to get it home and called roadside service after the dealership wasn’t able to answer any questions about when I could get it in for service. I needed to turn it around for the tow truck so I drove it down my street and back with no issues, hybrid drive engaged, error messages disappeared. I called off the tow just because I know I would have the dealership tell me there was no faults present.

Omg......I think there is a trend here with these errors popping up. I just had my first experience with loss of power, engine hesitation, hybrid/system/drive-control malfunction warning lights on. Next time, if this happens I will definitely take a video in real-time so that the dealer sees what I'm seeing. This issue occurred ~4K of total driving miles. I then immediately decide to call Roadside. Towed it to the dealer and they basically told me, 'Everything seems fine'. The codes went away.......arrrgggh! Bad timing and time wasted. I hope Toyota is tracking these complaints so that a recall is issued if necessary! In my opinion, its a safety concern.

UPDATE: The issue with the infotainment screen not turning on happened again on 8/1. I took it to the dealership and they kept it for 2.5 days. They couldn't figure it out. Happened again on 8/4 but I didn't have time to visit the dealership again. At first I thought the Stargard was the cause, clearly it's not as the problem persists. The issue with the hybrid malfunction has not returned so I'm thankful for that.

I'm noticing my battery level never goes beyond 50%. My daily drive is typically 20-30 minutes max mostly freeway.
How are y'alls charging performance? Do we ever get to see a fully charged battery?

Never seen my fully charge in 5k miles. When I start the engine it is always at three bars no matter what the charge on the battery before the engine is turned off

 

[Stage7]

I wonder if the 12V battery is like a lithium ion battery as in if it sits for extended periods of time with no charge (like in port) it loses its capacity? I'm at 8k+ miles now and have not had any of these problems. I'm sorry you guys are dealing with this and that it can't be replicated is even worse because you never know when lightening is going to strike. If you could replicate it at least you would have a starting place for solving the problem.

I was subscribed to Toyota remote subscription so all the code errors were still logged there. Just a thought. I also took video, though my LC wasn't drivable.
