Unexpected Engine Failure in My Toyota Highlander – A Wake-Up Call for Toyota Owners

Unexpected Engine Failure in My Toyota Highlander – A Wake-Up Call for Toyota Owners

I’ve always believed in the reliability of Toyota. That’s why I’ve owned nothing but Toyota vehicles since 2013 – from Corolla to RAV4, and now a 2021 Highlander.

But on April 15, just 5 months after the warranty expired, my well-maintained Highlander suffered a complete engine failure on the highway — with no warning. Oil started pouring out, and I had to tow the car to the dealer. The diagnosis? Internal engine failure. The cost to repair? Almost half the price of a new Highlander.

I followed all service intervals — up to 90,000 km at the dealer and later at certified service centers like Petromin. Yet Toyota refused to cover the failure, saying the warranty had ended, and outside servicing disqualifies any support — even though this is legally acceptable in KSA.

This is not just a one-off case — it’s a serious manufacturing defect in a car trusted by many. Engine failure is not supposed to happen in a modern, properly maintained vehicle just beyond the warranty.

To all Toyota owners: be aware — Toyota cars can fail without warning, and you may receive no support even for critical factory-related failures.

To Toyota and Abdul Latif Jameel: This is a moment to reflect. Denying responsibility for such major issues just beyond the warranty period puts the brand’s reputation at risk. I expected better from a company known for quality and customer trust.

Let’s hope Toyota starts standing behind its products, even after the warranty ends — especially when the failure clearly isn’t the customer’s fault.

Not sure where OP is, but this is not a North American warranty/model. If it is the 2GR-FKS, I know that The Car Care Nut tore one down with 60K miles to address some leaks and found concerning amounts of wear on the timing chain guides. This was most likely due to the 10K mile oil change intervals, but he was a bit shocked at the wear.

Idk, what year that 2GR-FKS engine is, but I've been doing 10k mile oil changes on mine for 6 years with more mileage on the odo than that, and have seen no ill results. My tacoma still runs great. Car nut could be just putting out a fluke video just like a lot of his other ones, and you guys take it as gospel

Love this one:

Fixed it for him! Cheers!

10,000 mile / 16,000 km oil changes are a joke.
A master Toyota technician told me personally.

The transmission fluid advertised as "lifetime fluid" is not lifetime fluid either.

I change my oil every 8000km/6 months.
All depends on the motor oil and filter you use. I use to run 20,000 mile oil change intervals on my old 2020 VW 4 cylinder diesel. Last I knew that had over 200,000 miles on it and was still running strong! But was not running Dino oil!!! I've been running real synthetic oil for years, none of that grade 3 hydro-cracked stuff that they call "synthetic"!!!

I've spoke with techs at a local independent napa garage that specializes in toyota's saying they have customers with well over 250k miles doing 10k mile oil changes that this business of doing 5k mile synthetic oil changes, or less is totally unnecessary.

It's similar for me driving 8-9k miles a year. I change my oil every 12 months, or so also. I think a lot of drivers are in that bracket to. Short trips over a years time is hard on the oil, and a year should be the max. Not being in the severe category, I've been recommended 10k miles, or 1 year, what ever comes first.

Same people that believe


The same people that believe in 10,000 mile intervals are the same people that believe in Toyota Transmission fluid is lifetime fluid.
That depends on who's lifetime, toyota's, or yours. I had changed our prius cvt fluid which didn't appear all that bad at nearly 100k miles. This 2010 prius has been running so well the wife wants to keep it another year instead of upgrading to something new this summer.
