Found Truck bed floor rust corrosion in the bed of 2014 tundra. Bed has localized corrosion and rust perforation in specific areas on the top side of the bed. Bed assembly does not appear to have been properly sealed using hemming and sealing procedures outlined in CRIB bulletin:163 sealing Hem-flanges and body seams. The truck bed underside is rust free except where the bed sections were welded and sealed together. Truck is garage kept and has been undercoated with fluid film annually since I purchased in 2017. Truck only has 45,800 miles on it. Rust is forming in between the seems and spreading under the bed supports and around the bolts that secure the bed to the truck frame. I am concerned that the bed may become loose and fall off while driving down the highway if not replaced or repaired properly. Toyota had a TSB 0101-12 for older model tundras years 2007-2011. The service manager at my local Toyota dealership acknowledges the issue and agrees that the issue is unacceptable. Dealer also stated that this issue is common on generation 3 Tundra vehicles. I am currently working with Toyota Customer care to resolve this safety concern. Local dealer will not authorize repair due to vehicle age even though issue is a manufacturing defect.

The grill cowling has plastic pins that attach to hood. Grill cowling is the part that sets above actual grill via bolts, and plastic pins. The grill cowling is constantly popping out, plastic pins not holding. Have read on line that others are having this problem. If grill cowling becomes loose while traveling, and breaks or snaps off it will be airborne could cause vehicle crashes. Has not been inspected by manufacture, police, insurance reps or others. Is available for inspection.

In the course of cleaning my vehicle, I noticed corrosion on edge of door sill (emanating from under inside rubber door seal) of my 2014 Toyota Tundra on June 13, 2021. After removing the plastic scuff plate and rubber door seal, it was apparent that openings from the underside of the vehicle into the cabin are present from the design/manufacturing process - these opening are not sealed. The openings are not a result of corrosion but rather are associated with the geometry of the floor pan at the floor pan to rocker pinch weld - it is not a sealed surface. After removing the rubber seal I was able to look downward into the openings and see daylight from the underside of the cabin. Electrical cabling is immediately adjacent to these openings beneath the plastic scuff plate. It was apparent that the openings permit water and salt infiltration into the cabin, and would appear to be the primary cause of corrosion and build up of salt residues in the cabin and door sill area. My first impression was the condition that I observed was a manufacturing defect. On reflection many questions came to mind including: was the infiltration of water, salt and potentially exhaust through the openings in the floor pan going to have safety consequences - would the deterioration of the body structure as a result of corrosion have consequences in the event of a crash, or would the potential infiltration of exhaust gases affect the safety of cabin occupants? In following up the dealer and manufacturer over the last week, no resolution has been found. Owing to the age I was advised that there was no warranty coverage. The dealer reportedly inspected other Tundras and the design/manufacturing conditions (ie. opening in the floor pan) were the same as I had observed. It was only through my own initiative that I identified a Manufacturer Communication (NHTSA ID 10173991) that shed some light on the issue.

Three studs or lugs broke off my right front wheel while driving, causing it to completely break off and damage the right front part of my truck. Thankfully I wasn't driving very fast or it would of been much worse. I've taken it to the shop and had it repaired. The mechanics say this should not have happened. I'm afraid my other wheels my do this as well. My truck is a 2014 Toyota Tundra plat 4X4

Toyota - defective plastic materials used: The driver side mirror and wheel well melted from the sun while parked in my driveway. Toyota failed to use quality plastic material without uv protection and a higher enough melting threshold, which resulted in the driver side mirror and wheel flair melting from heat of sun. Under no circumstance, should sun heat melt a car part which should be designed to withstand sun heat outside. I contacted Toyota North America regarding this matter. I informed Toyota na that I purchased the truck in September 2017 and that the drivers side mirror and wheel flair melted in my driveway. The company offered to pay $200 for an $850 repair. I request full replacement and repair of my Toyota Tundra 2014, plus damages of $2,400 due to the time from work that was required to address this matter with the dealer and Toyota na.

I was driving down the road on my way top work when the sunroof glass exploded. I was on an open highway with little to no traffic around me. Nothing hit the glass, it just blew up. I read online that this has been a complaint on this make as well as many others. Cost to repair is in excess of $800. I could have had an accident because it scared me and I could have lost control of my vehicle. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).'

When I purchased my truck new and was on my way home I noticed a very small dent on the top side of my bed. I decided not to worry about it as it was barely visible nor did I want somebody to do bodywork to fix it. Longevity issues with after the fact body and paint work. Unfortunately as time went on and I was using my truck it started developing more dents on the top side of my bed. I now have 5 or more on each side. I have never hit the side of my bed with anything. Besides, all the dents are the same in appearance. Toyota says its my problem not theirs as it appears to be of an outside influence. I have seen other vehicles with the same problems as mine. Just not as bad. The truck is supposed to handle 1300 to 1800 lbs in the bed but when I load it with approximately 1,000 lbs it bottoms out over speed bumps. I think this is where the issues are coming from. The bed is flexing due to bad engineering and materials and causing ripples in the bed. Its unfortunate that I have to drive a brand new vehicle with dents and all they can say is its not there problem. I sent a certified letter to them dated March 18. Thanks for your help
