general problems of the 2012 Acura TSX

Check engine transmission abs vsa tpms all lights went on suddenly. While I was driving suddenly all lights came on dashboard. I’ve used obd scanner to find the root cause but the problem can’t be detected. I went to Acura dealer in NJ and paid $250. They inspected, and said it could be this instrument cluster or that ecu. But they did not said anything concrete what could be faulty. Both are expensive to replace around $2000-$4000 each the lights comes and goes. These lights are not persistent. I’ve been driving with it. Sometimes when the lights are on ac doesnt work, steering loses control for a second. When it loses control car swerves. It’s dangerous but I’ve been driving with caution ?? in past, electric power steering was malfunction and I had it replaced for $1500. I will never purchase Acura or Honda for lifetime it should be recalled.

For about a year or more, on cold start,(3-6+ hours of engine rest) rattle occurs for a brief period of time (usually 1-2 seconds) then ceases. TSB 09-010 is associated with various Honda models up to 2012, but does not include Acura. Car delivers no dtcs for this issue currently. Have not had the vehicle inspected by the dealer for this issue. Following the TSB, the symptom is the same. Replacement of vtc actuator will happen shortly, in which the part can be available for inspection.

On 7/3/2013, I took my car in to the dealer for service because it had demonstrated several episodes of engine hesitation. I have always used premium gas. The car was checked, but the symptoms were not observed and no cause could be determined. On 9/19/2013, I returned for an oil change (annual service) and also asked if any engine hesitation service bulletins or advisories had been issued. None had been. These episodes: •have occurred about 15 times while owning the car. •have all occurred when accelerating moderately from below 20 miles an hour. •have occurred under all combinations of engine and air temperatures. •last from 2 to 3 seconds, while the engine does nothing. •are intermittent and cannot be summoned upon demand. On some occasions, the hesitation has put me at risk of collision, where I could not go forward but had to brake. The risk of nonperformance is always present and is a constant source of dissatisfaction for me. Based on my limited understanding, my guess is the cause involves a sensor or computer.
