Problems with 1999 Volvo S70 POWER TRAIN

Twice, within 50 metres of the same spot each time, my car has suffered extreme acceleration whilst i was braking as hard as i could. first time, my mechanic checked all computer diagnostics using two different computer testing devices but there were no fault codes. now, as well as happening twice within 50 metres of the same spot, i was at the same set of traffic lights, which i do not suspect as being the problem, but also next to a major hospital with an adjacent helipad. my best guess after 57 years in electronics and 40+ in computers is that some sort of rf interference is upsetting my vehicle. i know volvo check all accidents involving their cars in sweden and wonder whether they have ever come across my problem. both times the engine screamed its head off although i had no time to worry about the tachometer reading. the noise itself was adequate warning and the lack of braking meant that i had to kill the ignition to recover mine and the vehicles composure. switching on the ignition again both times, the vehicle once again idled normally and operated as it should. *tr

My 1999 s70 with approximately 92,000 has the following issues: - sometimes the engines start shaking? - hard to brake - no power even if you pedal is at the max - cruise control stop working my car has a malfunction with the electronic throttle module and i have been to the deal to get the software upgrade. since the upgrade my check engine light came on and have had to replace my front 02 sensor. now the car is undriveable because it will not go more than 20mph with the gas pedal floored. volvo will not repair this know issue because the car is 10 1/2 years old. they state if the car was less than 10years old or under 200k in mileage they would repair it. this is not fair. they could have replaced this etm when i came for the software upgrade but they did not. *tr

Dt*: the contact stated the clutch does not always engage and the vehicle accelerates and decelerates on its own. the vehicle has been taken to the dealership, but there are no codes on the computer.

Car stalls randomly and this time i hit a curb

While the vehicle was parked in the driveway the three year old child was able to shift the vehicle out of park. vehicle was not running, and there was no key in the ignition switch. while the vehicle commenced to roll down the driveway consumer tried to stop the vehicle. driver's door knocked the consumer down, and the child fell out of the vehicle. it continued to roll until it hit against the curb. both driver and child sustained injuries, and were transported to a local hospital. vehicle was not inspected at this time.*ak

The consumer had difficulty controlling the vehicle because of a failure with the rear end and rear tires. the problem worsened when accelerating and decelerating. there's was also a nauseating tar like smell within the cabin of the vehicle. the dealership indicated the transfer case had shredded which caused an oil leak. the part couldn't be replaced for almost three weeks due to a nationwide back order. *jb after 3 and a half weeks the transfer case was replaced. within 48 miles the vehicle began to exhibit symptom of the previous failure. the vehicle was taken to a different dealer. the technician indicated that both failures were secondary to the tire dealer putting an incorrect tire size on the front passenger side of the vehicle. this caused the vehicle to register that the tire was constantly slipping. *nlm
