Serious engine speed surging. Jumps to over 8000 RPM. Happens when stopping on occation, not always. I could have got killed while backing into my driveway on a hill. I have seen this at least 4 times and will not drive it. I informed my insurer. At dealer now, they say they have never heard of this and cannot duplicate. Lots of info on web from others who have same problem. It seems to be a throttle control issue and class action suit has been done on years just up to 2016. Volvo have extended warranty for the throttle module and ECM. I asked the dealer to research on this and if they cannot duplicate than replace the likely suspect and software as well as contact Volvo for help. If this is a known issue, Volvo needs get info out as someone is going to get hurt or die due to this known defect and should pay for the repairs. I love the care but will not drive it as it is. 63K miles on it. Please feel free to call or email. Thanks brad lopez lopez.brad@gmail.com 408-332-8846

After driving for about 20 minutes in 77F, sunny, dry conditions, I'd come off the freeway and stopped for about 15 seconds at a light to make a left turn. When I started making the left, someone blew through the red light to turn right coming from the opposite direction right in front of me. I let off the throttle but the throttle did not release. I was going about 15-20mph with the engine around 2,000rpm in, most likely, third gear. Since I was at low speed, I promptly tried gently tipping in the throttle to see if I could close but it did not so I immediately put the transmission in neutral. The motor revved up to about 4,000rpm which is a natural idle for this motor if the transmission is in gear and the motor is under load at 2,000rpm. After seeing it rev up, I put it back in drive and it jerked into gear because the vehicle was still on throttle. Suddenly the throttle cut and it returned to the normal pedal travel vs. Acceleration response relation. It felt as though the car had cruise control on. I could make it go faster but the motor wouldn't rotate any slower than about 2,000rpm.
