See NHTSA complaint number 10949504 Feb 3, 2017 that reflects a second tire in the same driver front position when it lost pressure due to a crack in the sidewall while sitting in the driveway the morning of Feb 3, 2017. The pressure had dropped from about 38 psi to 26 psi over about 2 days it had been parked. I got it to a corner gas station about 1 mile away who where - losing another 2 psi while traveling and the mechanic detected the sidewall problem indicating it was a tire defect and it would be best to take it to the dealer/service dept. It was re-pressurized to 38psi and other tire pressures were checked (no problems). Going the few miles to the dealer, the tire lost 4-5 psi pressure. I was told by the dealer/service manager that the tire needed replacement and that it was something I might have done and not a tire problem. The sidewall defect seems a safer duplicate of the first tire failure (that happened on the interstate during slow moving traffic and with four adults in the car - NHTSA complaint 10706538, 4/19/15). Note that both tire failures the two on the driver's side. Tire rotations are done front/back on the same side, onstar and I both monitor tire pressures, tires have not been driven under or over-inflated, failures have both been in the driver front position (heaviest load).

This is the second Goodyear assurance fuel max 94V tire that came on my 2012 Volt that failed in the same driver front mounted position. See NHTSA id # 10706538 date reported 4/19/15. This incident happened this morning, in the driveway. When I started the care, pressure was reported at 26 psi, down from 37 psi when the car was parked two days ago. Taking the car for check to the corner exxon station, the mechanic checking the tire saw that the sidewall had a crack and mentioned this was a tire defect. He inflated the tire to 38 psi so I could drive the car to the dealer since it was thought that the dealer service department would be the appropriate place to possibly document the tire problem and have it replaced. The tire lost 5 psi on the 3 mile drive and I was told by the service manager that I must have hit something, or driven with the tire underinflated; that if there was something wrong with the tire, there would have been a recall. He mentioned had never seen another Volt with a defective tire. However, in 45+ years driving, I've never had this experience with a tire, knowing the tire had never been underinflated - 34 psi has been the record lowest - (since I monitor the tire pressures). The tire was one of the original tires on the car and the second one failing in the same way. This time, I was not on a highway, the leak started while parked in the driveway and the sidewall crack was apparent in the exxon station.

2012 Chevrolet Volt was purchased new. Tires have about 16,000 miles. Sidewalks are cracking, consistent with "dry rot". one tire the sidewall blew out while driving. Another tire has dangerous looking cracking. Tires are not that old and this level of deterioration is abnormal. Dot number 43br janr 3311 Goodyear assurance fuel max this sort of failure can lead to death or personal injury.

The tires have been on the car with correct pressures since purchase Oct 2012 and proper rotation. Pressures are monitored. On the incident date, I had driven approx 80 miles at speeds under 60 miles/hr with no heavy breaking, on smooth road, when suddenly, on the interstate, the tire began loosing pressure from 40 lbs to <34 lbs (with car warning). With pressure going steadily down, I was able to safely get off the interstate onto a side road and church, where I saw the sidewall had split with air escaping (now 24 lbs pressure). I called onstar and used the emergency pump and rubber goo to try and stop the air escaping and was successful at halting the leak, building pressure back to 29 lbs. I drove the care with onstar on line to drop off my passengers living nearby, and then had the tow truck come to pick up the car to take to the dealership. The car was delivered at the dealership with the tire pressure still at 23 lbs. I was told I would have to buy a new tire and canister, and that the occurrence was not a design problem of the tire. I had never noted any prior problems or defects in this tire, and in 45 yrs driving, have never experienced a tire failure like this. Noted is that the tire pressure is much higher than any tire I have owned. There is considerable salt put on the roads and I've had other tires I've had to replace at 5 yrs. While I knew I would need to pay for the tire, I'd asked that the tire and others be taken for a better investigation and that I had strong concerns about safety given how the tire had failed. I have notified Goodyear (ref number 145-9946) and Chevrolet - chat advisor and Volt advisor group. I also notified my insurance company usaa. On the Volt forum, there is a similar description of a sidewall leaking escaping air with the car at home.
