I have a 2007 Tundra DC trd truck. I replaced the oem tires at 19500 miles (bfg rugged trails) with Michelin ltx AT2's March 2009. I now have 23,800 miles on the truck. Now anytime I go over any type of bump regardless of speed the bed bounces so bad that it vibrates up through the cab. The bed bounced before but not this bad. I feel it in the drivers seat. If I drive on a back dirt road the back end bounces all over the road. I brought this to the attention of the local dealership and they said they hadn't heard of this problem when I reported it in September of 2009. Now that the mechanic called Toyota headquarters in ca, he said there were numerous complaints and that there was no fix for it. Service manager said it was the tires. Dealer recommended I add weight in the bed, I added 5 sandbags, 300 lbs (winter is almost here) and it made no difference to the ride. I believe this could lead to a serious accident if not corrected.

While traveling down the highway there is a very noticeable bounce coming from the back end and it doesn't matter what highway it is on it does it when ever you get over 65 mph.

Bed bounce is horrible on my 2007 Tundra. Not only does it happen at speeds of 55-70 on the highway, but gets very shaky when slowing down to turn. It has made me very uncomfortable driving, because I am more concerned about the bed bounce than the other traffic around me.

Bed bounces and shakes excessively. Toyota is aware of the defect but refuses to correct it. This condition can cause vehicle instability and driver fatigue, especially at highway speeds on concrete roadways.

Severe rear end oscillations/bouncing causing blurred vision on part of driver when traveling on concrete highways/freeways at any speed.

2007 Toyota Tundra double cab 4X2 5.7ltr V-8. vehicle has an extreme and dangerous "bed bounce" or vibration at all regular highway speeds on concrete type freeways with expansion joints. The vehicle becomes very unstable and feels as if control will be lost. It is completely unbearable. Dealer reports similar complaints from other 2007 Toyota Tundra owners. All 2007 Tundra models exhibit this failure and it stems from a design flaw in the chassis/suspension. Event began from the day the vehicle was driven off the dealership lot (11/25/07) and continues to date. Toyota needs to address this serious matter and correct the issue.

The contact owns a 2007 Toyota Tundra. While driving 55 mph, particularly on certain concrete surfaces, the rear of the vehicle bounced violently and oscillated. Toyota stated that they were aware of the failure, but there was currently no remedy available. The purchase date was unknown. The current mileage was 4,000 and failure mileage was 100.

- Lakeville, MN, USA

The vehicle bounces horrible at speeds of 60-80mph on concrete freeways. As per dealer I have added 200# of added weight to the rear, to which the problem still occurred. The bouncing is very noticeable in the rear seats, so much so that I am not comfortable having my 2 year old daughter as a passenger. This is unacceptable since we purchased this as a family vehicle. I have inspected the tire pressure and have not had any noticeable effect on the bouncing. I feel the vehicle in unsafe on these roads and could very easily become unstable.

There is an issue with the 2007 Tundra suspension that causes a mechanical resonance on various concrete roads. This results in a "shaking", "bouncing", "wobbling" that is seemingly severe enough to cause injuries in young or elderly passengers at legal speed limits. Furthermore the wobbling could lead to accidents due to loss of control at higher speeds. I am certain that if this issue is not addressed, it will eventually lead to injury. The dealer has stated that this is "normal". however, using any good judgment at all, I would not consciously expose an infant passenger to this "normal" wobble. This occurs on roads that consist of concrete slabs. Southern California is an area with such highways. I have experienced this issue on I-5, I-405, I-110 to name a few.

Unresolved safety issues with 2007 Toyota Tundra: 1. towing mirrors vibrate, previously reported Toyota case # 200704230738. Mirrors are unusable above 40mph due to vibration. 2. bed bounce is so severe on some roads, particularly I-10 between indio and los angeles, that it is impossible to carry on a normal conversation. Dealer response to both issues has been they all do this, so they cannot make a fix until Toyota comes up with a solution. Internet reports prove that the dealer is correct: All Tundra have these problems. Thus the problem is not with the dealer, but is indicative of first-year production problems. Hopefully Toyota can resolve this to avoid invoking lemon law protection.
