Opel Insignia motor A20NHT irregular acceleration problem
Hello,
I´m sorry about writing in english. I am from Sweden and bought a Opel Insignia Sportstourer Cosmo 2,0T with engine A20NHT in springtime 2010. Several problems has accured.
* There is irregular acceleration when acceleration is done from low speed and low RPM in mainly the first three gears.
* This irregular acceleration is much increased when the speed cruise control is activated and the motor has to work a bit, when there is some load like a empty trailer with hard housing behind. The acceleration problems is then coming when acceleration is done at the jog wheel for the cruise control in fifth gear and a speed at 70-80kmh.
The local Opel dealer (Kronobergs Bilaffär) said that they could find the problem and that Opel Germany knowed about it and would fix it after the summer vacation 2010. The Opel CCDM Sweden guy later on tested the Insignia and told another story. He said it was normal and the engine system sensed according to him in two steps how much power that is needed to proper acceleration. CCDM guy also told there was no priority from Opels side to fix it, so in other words he admitted that it was some kind of problem. CCDM guy is speaking with two mouths I think, and I have bad experience from this CCDM guy before when I owned a Opel Vectra -08 with servo and gearbox problems.
The problem with this Insignia is that it´s not only irregular in two steps, it´s irregular up to seven-eight times in low speed and low RPM, when acceleration is done by foot-to-pedal, and less than half gas is given.
When accelerating with the cruise control jog wheel the acceleration is standing still and the whole car becomes jerky/spasmodic so much that I don´t dare to keep on giving this commando.
Nothing happens from Opels side and I will let this matter go to Swedish complaint board (ARN).
Have any other Insignia owner here the same experiences?

Last week my Insignia 2,0T A20NHT started to jerk really much (irregular acceleration) and the problem has increased a lot, but the worse jerks has gone away again.
FOH where I bought the car tested it and said "can´t really sure notice any irregular acceleration, it´s maybe because the road" I told him that I see this words as a lie. Then he wanted me to drive and then he could feel it but not for sure.
Drove to another FOH that immediately noticed the irregular behaviour. Now I want Opel definitely taking the car back. It´s more than one year since I told them about the problem and nothing has been done about it after several mail and phone calls from my side.
This week I will drive to a testcenter and get the trouble at paper. Then lawyer/swedish court shall handle the matter.
Have anyone more experienced this problem with A20NHT Insignia?
