Struck a pothole heard a clank. On the rest of the way home from Pa. kept hearing a rattle and metal hitting metal every little bump. Crawled under vehicle when we arrived home here in Rhode Island and discovered second leaf spring had broken in front of the axle. Went to dealer to see about fixing it and was told it is out of warranty. Got a price for parts there and got a bit of sticker shock for the same springs with no improvement in quality. Seems it is wrong for these parts to fail under 100k miles. Sorry but my 1970 Ford Pinto seems to have done better in this department although I gave my Ford pickup up for what I thought would last me many more years of trouble free ownership. Was I wrong? Now I found my vehicle in the area isn't the only one with this problem. Several repair shops told me they have replaced or fixed the rear springs on several Tundras with the same problem.

Update from Jul 21, 2019: Toyota quoted me $3327.00 for parts to repair the problem. No labor was added in the cost.Fearing more damage I searched for a recommended shop and bought nessesary parts from Palmer Springs in Providence for around $700. took to the shop and $700.00 for labor to repair. If the broken spring had turned toward the outside of my tuck the damage would have been much greater with possible personal injury added in.

In the past ive heard some noises under the truck, I though it might have been just kicking up rocks or something under my truck, it wasn't until about two weeks ago I ahd a friend following me and noticed my truck was sitting lower on one side, upon investigation we found 2 of 3 springs broke on one side and one on the other side, last week I felt it again while driving normally on pavement at 35 mph, I stopped and looked and the 2nd spring had broken. Now my truck has only the one main spring on each side, its scary to think if one more broke on either side it would put my bed on the axle and cause a serious accident. I am now forced to keep the vehicle parked until I have funds to replace the rear springs. Ive owned this vehicle about two years, ive never towed ro hauled much weight with it, but at this point I cant even drive it and if I did, I wouldn't be able to haul or tow and theres no way id take it farther than a few blocks to the gas station. Toyota really needs to consider a recall on these springs or fix this issue, leaf springs aren't suppose to just break like this without abuse to the vehicle. I do not recommend anyone buy a vehicle from Toyota unless they are using a different model or manufacturer for their leaf springs.

Here is a a copy of the letter I sent to Toyota Canada:

I'm writing in regards to a safety concern I have with my 2010 Toyota Tundra TRD. Recently I was driving down the road when I heard a loud banging coming from the back end of my truck. When I came to a stop I noticed that one of the leaf springs had broken in half on the drivers side of the truck. The sharp edge of broken spring had wedged itself against the front of the tire. Had I been going down the highway like I was doing the day before this could have ripped the tire to shreds possibly causing an accident. I noticed the broken leaf easily swung around coming in contact with the gas taken and potentially hitting the brake lines. I took the truck to a suspension shop that showed me this vehicle had another leaf already replaced in it's lifetime. I also noticed the remaining leafs were very rusty. Between the broken leaf, the previously replaced leaf and the rust I decided to go ahead and replace the leafs on both sides of the truck as I no longer felt they were safe.
