There is a know defect with the chassis used for several Volvo car models. My car is a Volvo C70, year 2012. My car is affected by this defect. The defect wasn't disclosed to me at time of sale. I only learned about it literally 10 years later when Volvo of Gilbert (dealership) advised me to install a costly part on the rear suspension of my car because of "excessive negative camber". According to the Volvo repair department, they've known for years of an internal repair "recommendation" memo issued by Volvo that Volvo actually pays for on other models, but won't pay for on mine, to correct this "negative camber" on the rear of the car. ***** The negative camber causes tire walls to fail early and abnormally wear the internal edges of the tires. I've experienced early tire failure on multiple sets of tires on my Volvo C70 and never knew why. Now I know. **Volvo has always known.** I have to replace all of my tires almost every two years due to the inside edges wearing out, despite faithfully rotating my tires several times a year. My tires have worn down to the belt on the inside edges despite having plenty of good tread left in the middle of the tire itself. About two years ago I had a dangerous blowout on the freeway because of a tire that failed early -- now I know it's because of the negative camber. More recently, two of my tires wore down all the way to the belts despite being less than two years old. ***** Volvo knows about this issue. There is a good paper trail of the issue being documented both by Volvo and their customers, but they failed to warn us of the dangerous car suspension and failed to provide the fix to all of us (while providing the fix to some of their customers). ***** Please listen to this 2-minute recording with the Volvo technician (Judd) who disclosed the known defect to me: [XXX] ***** This needs to be rectified for all of us with the faulty chassis'. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This occurred after driving for about an hour. While driving at a fairly high rate of speed, I felt the driver's door move slightly. The dome light came on indicating that the door had opened. The windows were down so I cannot state if they would have slightly lowered as they normally do when the door is opened. I pushed outward on the door to see if it was fully open. The latch held the door. Using the interior door handle, I then opened and closed the door. The doors were then locked as extra security. Approximately 30 minutes later this happened again on a busier highway. I then had to worry about the door opening on me again while I was driving, however, there was no further occurrence. Later after returning home, I performed an internet search to see if something like this had happened to others. After seeing other comments of C70 doors opening & door latch problems, I decided to report the problem to get it on record.

Drivers door without warning while driving at high speed suddenly unlatches, hazard light and warning indicator that door is open is shown.Besides being very dangerous it is very scary.My problem has not been confirmed by dealer but was reported to dealer as far back as 7 years ago.

The large coupe doors on this vehicle have a tendency to become unlatched while driving requiring the need to stop the vehicle and re-open and close the doors. This happens when doors are locked as well as unlocked. When this happens on the highway at high speeds, it is very dangerous and difficult to hold the door closed while making your way to the side of the road to correct the problem. This happens with no warning. There are recalls by Volvo for this exact issue on several other models but not the C70. I have reported this issue directly to Volvo customer service. I am also aware this is a widespread issue as I have have seen it identified by several other C70 owners on various Volvo Owner Internet forums.

When driving and operating the vehicle with the top door the door becomes ajar on the passenger and driver side with a slight bump in the rose.

While on highway at highway speed, the driver door moved outward as if it was opening. The open door warning light flashed on the dash. Makes you feel like you're about to fall out of the car. Had to stop and close the door again. Would hate to have this happen while cornering.
