Mileage when the problem started
What owners report
The contact owns a 2019 Toyota 4Runner. The contact stated while driving 50-55 MPH and attempting to overtake another vehicle, the vehicle failed to respond while depressing the accelerator pedal. There was a 15-second delay in the vehicle response. There was no warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the fuel pump needed to be replaced. The vehicle was repaired; however, the contact stated that the failure had been reoccurring increasingly while driving. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 10,000.
My 2019 Toyota 4Runner was inhabited by a rat that chewed the wiring harness in at least 3 different areas. The damage occurred between 8pm and 7am. The vehicle started with lights on the dash illuminated. The car was out into drive and was jerking. Reverse had the same result. After inspecting under the hood of the car wires were seen chewed partially and a few completely severed. A rat was seen under the manifold cover. I used an air hose to evict it and had the car towed to dealership. The bill was just under $1000 to repair. I was warned it could have been worse ($6000) if harness needed changing. I was told "I was lucky". After researching I discovered this is a problem because of soy based wiring. It's an attractant for rodents.
The contact owns a 2018 Toyota 4Runner. The contact stated while driving approximately 25 MPH, the vehicle stalled. The traction control and check engine warning lights were illuminated. The vehicle was towed to a local dealer to be diagnosed. The contact was informed that the fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 30,500.
On7/2022 when I came out of my house in the evening my 2018 4Runner was not been running for hours But I heard my Fuel pump running with no keys in the switch Would not stop running until I turned the switch on and then turned it back off and then fuel pump stopped running I reported to my dealer but they didn't seem interested so I am Sending this to you any thing I tell the dealer where I got my 2018 4Runner Service dealer seems to go unheard. I got my 2018 4 runner brand new in 2018 and I was having issues with the 4Runner Shaking in the front end and steering wheel and took it back more than 5 times but only to be told it was nothing but. I am still having problems with it but they have not fixed it or anything
My 4Runner is hard starting all the time. I've replaced the battery, tested the alternator etc. It sounds exactly like the problem of the fuel pump recall. The 4Runner was recalled from 2014-2015, my car was technically put together in Sept 2015, but is labeled a 2016. I believe my fuel pump is failing. I am extremely nervous it is going to not start one day while I am out camping.
Driving last week and check engine light along with traction control light came on. Hooked my ob2 scanner to port but came up with no codes. Drove it a few more days and eventually lights went out. Fast forward a week and lights came back on. Same routine with the ob2 but this time the code p2443 came up. Googled it and " secondary air injection system switching valve stuck closed bank 2". Found out there is a huge history with this problem not only with my 4runner but with tacomas, tundras and sequoias. With certain years of tundras and sequioas, Toyota has paid for this fix. Why not the 4runners and tacomas??same problem!! This whole thing is a big sham . It will cost about $2000 plus for this issue to be fixed. Where I come from, this is robbery. Knowingly selling vehicles with a expensive problem and not recalling them to be fixed.
Toyota 4 runner had a recall for the fuel pump. I have been having starting issues with it ever since. The power is good and the starter tries to turn the vehicle over. But the vehicle won't start. I have taken it to multiple locations for service through out the chicago land area. Also once the vehicle finally does start. The R.P.M.s will suddenly increase and decrease to the point that the vehicle turns off while in drive. I can provide print outs when the vehicle gets fixed, if ever. I purchased the vehicle as CPO.
About 4-5 times per year for the past 4 years my vehicle will hesttate or stall for 3-4 seconds when trying to accelerate after stopping at a red light or stop sign. This happens intermittently, at no regular sequence, and without warning of any kind. I have not received a letter from the manufacturer about a recall, but the NHTSA informed me that a fuel pump recall notice was made public on January 20, 2020. I have contacted my local dealer on two occasions, but they tell me the same thing each time, that I need to wait on a letter from the manufacturer telling me that they will remedy the situation. As of this date, 4/23/2020, I have not received such a letter, and the NHTSA says the same thing. My understanding is that the manufacturer has to send such a remedy letter within 60 days of the public notification, and that time period has expired. …
