On the other hand, let me share anyway! The letter was addressed to his staffer. I am certainly not a lawyer, so read at your own risk:

Dear Erica,
As per our conversation on 2/25/14, I would like to bring a matter of highway safety and consumer protection to the attention of Congressman Sires regarding the Jeep Wrangler (2 door) and Jeep Wrangler Unlimited (4 door) from model years 2007, 2009, 2009, and 2010 manufactured by Chrysler Group LLC.
The issue I wish to share is regarding the front suspension and steering of these vehicles. These model year Jeeps are known to become suddenly unstable while at highway speeds due to what is commonly call a Speed Wobble (Reference #1), also known as a “Death Wobble”. When this occurs, the front wheels and the steering wheel shake violently until the vehicle is slowed well below approximately 35 miles per hour. Until this violent shaking is stopped, it is extremely difficult to hold the steering wheel as it shakes back and forth up to 10 times per second.
I recently experienced this sudden and dangerous “death wobble” situation firsthand. I own a 2008 Jeep Wrangler Unlimited. It is important to state that I have owned my vehicle since it was new, and I have always taken it to a Chrysler dealer to perform recommended service and mechanical inspections. Additionally, my Jeep has only 48,000 miles and has not been modified, involved in any accident, nor used for anything other than normal road use. This past January, my vehicle suddenly and without any warning began to violently shake while driving at 65 mph on a highway. I immediately reacted by reducing my vehicle’s speed but was only able to stop the shaking after I slowed my vehicle below 35 MPH. After explaining my experience with this “death wobble” issue to the Jeep dealer service department, I was extremely surprised and concerned that the dealer was not properly informed of this problem. Relying on my (i) personal experience spanning 13 years with vehicle suspension modifications, (ii) college education in physics, and (iii) professional experience in heavy machinery failure diagnostic processes, I took it upon myself to research what could be the root cause of such an issue. (I share my qualifications only to highlight that the average consumer may not have knowledge of or practice with relevant resources to study and understand the mechanical issues at hand, forcing most consumers to be reliant on the dealers’ service capabilities.) From this research, I was most disappointed to learn that a common source of this Speed Wobble can be traced to Chrysler designing the steering components using a 14mm bolt through a 15.5mm hole in a key component of steering stability. While such a design can be perfectly acceptable if regularly inspected for appropriate torque setting, Chrysler fails to provide any recommended inspection interval or procedure to ensure that these or any steering component bolts are properly tightened. In spite of sharing this additional knowledge with my dealer service department, they were unequipped to properly diagnose the issue. Not realizing the depth of this whole matter at the time and relying on their assurance, I allowed the dealer to perform the service they recommended. I was further concerned when I experience this same problem very shortly after, confirming that the Jeep dealer did not successfully correct this dangerous situation.
Through further research, I have come to learn that Congresswoman Ashoo and Congressman Waxman of California have jointly addressed this issue to the NHTSA (Reference #2.) and Chrysler (Reference #3.). I have discovered that the National Highway Traffic Safety Administration (NHTSA) has reviewed this matter and determined that such an event does not pose a hazard because they believe that it does not result in a loss of control. Having experienced this situation myself, I must respectfully disagree with the opinion of the NHTSA on the grounds that needing to suddenly slow a vehicle to below 35 mph while on a 65 mph roadway is a hazard in itself. Furthermore, it stands to reason that not all drivers who experience this Speed Wobble will have the adequate presence of mind to be able to safely operate a vehicle while the steering wheel is violently shaking.
The only clear advantage that I was able to learn through my research for a smaller bolt being inserted into a larger hole is for expediency on a factory assembly line. While this ease for manufacturing may not be the reason for this design, such a simple oversight which contributes to this dangerous “death wobble” condition is an unacceptable allowance. In acknowledgement of this design weakness, many aftermarket companies offer simple kits to replace the applicable bolts for the Jeep steering system, ranging from $40 to $80. Additionally, Chrysler has redesigned the key component mentioned above to have a matching 14mm hole with the 14mm bolt for the 2011 and newer model years.
In response to this Congressional inquiry, Chrysler has issued a Technical Service Bulletin (TSB) (Reference #4.) Unfortunately, this TSB is extremely vague and initially puts responsibility upon the consumer by assuming this issue is caused by modifications after the purchase of the vehicle. Also, the TSB does not provide for inspection intervals or recommend an upgrade to enhanced bolt design. Chrysler’s response to this matter is a clear indication that Chrysler understands that this matter needs to be resolved. It is my experience that it has failed to do so.
Beyond causing a sudden and immediate safety hazard, experiencing a Speed Wobble can have permanent damaging effects to the vehicle that are beyond normal wear-and-tear. Violent shaking similar to a Speed Wobble can quickly damage the major metal steering assembly components as well as causing premature failure of common “wear items” such as bushings and joints. By failing to include the appropriate inspection procedures as part of scheduled maintenance, Chrysler has allowed these vehicles to unnecessarily suffer significant damage costing hundreds of dollars if such a Speed Wobble event should occur.
From this experience, my personal concerns are threefold:
(1) I have lost the confidence to allow my family members to drive this vehicle knowing such a potential hazard exists.
(2) By not properly informing me of appropriate maintenance for this vehicle, Chrysler has caused my vehicle to suffer substantial damage.
(3) There are over 500,000 of these vehicles on our roadways that could experience such a control issue without notice.
For all these reasons, it is clear that Chrysler must take additional action to remedy this situation through stronger communication to its dealers with the possibility of a limited recall on affected vehicles.
After fully reviewing this situation, I realize that my recent experiences fall exactly into the category addressed by the Congresswoman Ashoo and Congressman Waxman. The fact that I experienced this hazard nearly two years following their inquiry confirms that additional attention must be given to this matter. In addition to the apparent safety concern, I think the vehicle damage described above is a consumer protection matter that Congresswoman Ashoo and Congressman Waxman did not fully articulate in their formal public correspondence. As a resident of Hoboken, I would ask Congressman Sires to examine this issue of serious public safety. With the support of his good offices, I would hold myself ready to share additional detailed support for this matter.
