Transmission makes whine noise upon accelerating. Cannot be fixed except with new transmission. The longer you drive, the longer it affects and damages other parts. Mechanic was amazed that my relatively new Toyota needed over $10k in repairs. Toyota denying there’s a problem.

The transmission has a whining, grinding noise and occasional jerks vehicle. I had dealership look at the vehicle and they said it's a problem with this model but Toyota has not done a recall they issued a service bulletin. I was told it needs replacement but Toyota has been reluctant to work with owners outside of the service manufacturers warranty. This proved true, I was denied any goodwill assistance, and after several days of requesting why they denied any assistance, I'm not able to get an answer. This is a safety issue that they are aware of and not taking proper acceptance and assistance in rectifying. We carry our new born and toddler grandchildren in this vehicle as well as elderly parents. The thought of a total transmission failure on a busy highway or street is terrifying, I asked the dealership service manager about the safety of driving the vehicle and he recommended not operating it until it's replaced. In my[XXX] I haven't asked the government for anything, but I am asking you to look into this matter and if called for mandate a recall..

The transmission is making a whining noise when accelerating. I took the vehicle to a Toyota dealership and they said the transmission needs to be replaced. And I asked why the Highlander only has 58 thousand miles on it. How is it already going out. And they couldn’t give me an answer

My transmission started whining at 63,000 miles and my mechanic said it needs to be replaced. However, there is a nationwide backorder on Toyota transmissions. That should be a sign to NHTSA that this is a widespread issue and needs a recall! Of course this was right after the 60,000 mile Toyota warranty. I have extended war…

My transmission started whining at 63,000 miles and my mechanic said it needs to be replaced. However, there is a nationwide backorder on Toyota transmissions. That should be a sign to NHTSA that this is a widespread issue and needs a recall! Of course this was right after the 60,000 mile Toyota warranty. I have extended warranty but it doesn't cover consultations or taxes.

I have a 2021 Toyota highlander platinum. The car makes whining noise when accelerating my car has 70k miles and according to Toyota my warranty expired at 60k miles it’s a common issue with these cars and Toyota knows that but they won’t help with the fix. This affected a lot of people and they want almost 11k for a trans replacement. If it’s a common issue with all their cars then they should take full responsibility and fix the cars. I hope you guys could be of help and hold they accountable.

Routine maintenance was done 5000 miles ago. Routine maintenance. At 50,151 miles and routine 50,000 mile maintenance a whistling/whining sound was noted. I was told a new transmission is needed. PLEASE MAKE THIS A RECALL. PLEASE MAKE TOYOTA STOP CHANGING OUT TRANSMISSIONS AT 50,000 miles on the regular. There is a known TSB, but so many VIN's are outside of this range experiencing the exact same issue that it is inconceivable that Toyota doesn't know they have a problem. Having a warranty that covers it is a band-aid. The wear and tear on the overall engine and parts due to transmission failure means they are knowingly selling cars that will fail. Why isn't it told to every buyer to expect transmission failure at 30-50,000 miles at the time of purchase? TELL US AND THEN LET US DECIDE IF THAT IS HOW WE WANT TO INVEST OUR MONEY IN OUR CARS. My first Toyota and my last. AND what is worse, the NHTSA KNOWS about all these incidents and just lets it ride. We have lost the consumer in the values we hold as a country. Insurance doesn't mean insurance. Transmissions are only worth 30-50,000 miles when it should be 200,000+ by now. Quality standards are there for a reason. Having a powertrain warranty that protects the manufacturing IS NOT how it was intended. FORCE TOYOTA TO FIX THIS ISSUE. STOP SELLING CARS WITH FLAWED TRANSMISSIONS. I feel taken advantage of and am stuck with a car I no longer want, (because as the service advisor said, "if it happens again, you will still be covered at no cost to you?!") - this is not ethical or technically sound.
